Dr. Uma Naidoo
Episode Overview This episode addresses anxiety, the most common mental health disorder affecting 1 in 3 people. Dr. Uma Naidoo, a pioneer in nutritional psychiatry, discusses how nutrition can aid in alleviating anxiety symptoms.
Key Topics Discussed
Understanding Anxiety
- Definition: Anxiety is characterized by physical symptoms (sweaty palms, racing heart) and can range from mild to debilitating.
- Diagnosis: Clinicians diagnose anxiety based on specific criteria, often noting its manifestation in other symptoms like insomnia.
- Rising Anxiety Trends: Anxiety disorders increased by 25% globally after the COVID-19 pandemic.
The Gut-Brain Connection
- Biological Link: The brain and gut are connected via the vagus nerve, allowing for bidirectional communication. Stress can alter gut bacteria composition, impacting mental health.
- Neurotransmitters:
- Serotonin: 90-95% of serotonin receptors are located in the gut, highlighting the link between gut health and mood.
- Dopamine: Food choices can disrupt dopamine pathways, affecting mood and behavior.
Dietary Influence on Mental Health
- Impact of Food: Nutrition plays a significant role in mental health through its effect on gut microbiota, which in turn influences neurotransmitter production.
- Food Addiction: Comparison of sugar’s effect on the brain to cocaine, emphasizing the addictive potential of ultra-processed foods.
Actionable Tips for Managing Anxiety through Diet
SOAR Approach
- S: Swap out one unhealthy food for a healthier option.
- A: Add more nutritious foods, particularly colorful vegetables.
- W: Walk or engage in any form of physical activity to alleviate anxiety symptoms.
CALMING Foods
- C: Choline (found in eggs and legumes)
- A: Antioxidants (from colorful fruits and vegetables)
- L: Liquids (proper hydration and calming teas)
- M: Magnesium and Omega-3 fatty acids (found in nuts, seeds, and fatty fish)
Practical Advice
- Mindful Eating: Focus on adding nutritious options rather than restricting diets. Acknowledge that all foods can fit into a balanced diet.
- Avoid Processed Foods: Be cautious of misleading food labels (e.g., fruit-flavored yogurts often contain added sugars).
Conclusion Dr. Naidoo emphasizes the importance of a holistic approach to managing anxiety through diet and lifestyle choices. Consistent improvements can be seen within weeks of implementing dietary changes.

0:14One in three people have anxiety. It's the most common mental health disorder in the world. And haven't we all felt anxious before? Palms sweating before a job interview. Losing your appetite before a looming deadline. A pit in your stomach when you get bad news. Anyone who's felt anxious knows it's not just in your head. It's also in your gut. Trillions of gut bacteria send messages to your brain. And these messages influence your mental health and vice versa. And this means that just a few hours of stress can change the composition of your gut bacteria. So if your mind is in a constant conversation with your gut, then the food you eat should be bringing you good news.
0:57So how do you eat to calm your mind? Well, today's guest wrote two books to show you how. Dr Uma Naidoo is a nutritional psychiatrist at Harvard Medical School, who runs the world's first nutritional psychiatry department at Massachusetts General Hospital. Her book, Calm Your Mind With Food, is a revolutionary full-body approach to relieving anxiety. Oh, and to top it all off, Uma's also a professional chef. You'll walk away from today's episode knowing how to gain better control over your anxiety, using the power of the foods you eat every day.
1:38Uma, thank you for joining me today. Thanks so much for having me. I'm excited to be here. Me too. This is a new topic for us and I'm really excited to have you. Now, we have a tradition here at Zoe where we always start with a quick fire round of questions from our listeners. It's designed to be very hard for academics because we have these very strict rules. So you can say yes or no. Okay. Or if you have to, you can give us a one-sentence answer. Willing to give it a go? Yep. All right. A decade ago, did people think there was a link between nutrition and mental health? No. Is there new scientific evidence to suggest that diet can change your mood?
2:16Yes. Does your brain communicate with your gut bacteria? Yes. Can a stressful day at work change the composition of your gut microbiome? Yes. Are there foods that might alleviate the symptoms of anxiety? Yes. So now you get a whole sentence for this one. What is the biggest misconception about anxiety disorders? If you change your diet in a good way, you can help lower your anxiety within one to three weeks. It's real and I've seen it. So we've all felt anxious at some point, whether it's a disorder or not. And I was thinking about when I feel anxious, I feel it like in all parts of my body. So I'm thinking like sweaty palms, my heart's racing, shortness of breath.
3:01And I think most of us also feel anxiety in our gut. So like loss of appetite, nausea, a sprint to the bathroom. But I'm really struck that you said that just 10 years ago, people didn't see much of a link between our gut health and our mental health. Can we start at the beginning? What is anxiety? Many different things, but there's specific criteria by which a mental health clinician can diagnose you. But in clinical practice, often there might be more symptoms. For example, anxiety often hides in things like insomnia. And often when I'm working with someone and we work to improve their dietary measures and through a nutritional psychiatry plan that includes looking at lifestyle and metabolism, their sleep improves.
3:48But most importantly, they realize that the sleep was actually being disrupted by anxiety. So it often hides in other conditions that we may report as a symptom. I think that's important to understand. And it's also important to understand that anxiety occurs along the spectrum. You might have mild anxiety that is somewhat appropriate before writing an exam, taking a test, some big event, but you might also have disabling, crippling anxiety where you can't leave your home or get to work or even get out of bed to a Zoom call because you are so warped by what you're feeling that keeps you frozen in place or unable to function.
4:30And that is a more serious, severe form. And it's important for people to understand that there's this almost linear or longitudinal way in which people can present. Could you help me to understand a bit more the difference between feeling anxious, which I think happens to all of us, and being diagnosed with anxiety. So if you're anxious for an exam, then you write your exam, and you're pretty happy after that, and you're hanging out with your friends, and you're doing okay, you're sort of returning to a normal baseline. Whereas if you are really struggling with anxiety, all moments of your day may be anxious, and there may be times when you actually can feel okay, but it's a short period of time and you start to feel anxious again.
5:17And often it's unprecipitated anxiety, meaning you walking to get a cup of coffee or you going to the gym or whatever it might be. And you start to feel your heart racing or you have the onset of a panic attack. And very often patients will tell me or clients will tell me, you know, it came out of nowhere. So it also has that feeling to it. And it tends to, over time, cause you to be able to function less at your peak. So you might be able to function, go to work, conduct what you need to do, but you may not be working or living optimally. Got it. And this is then diagnosed by a doctor, by a clinician.
5:59Yes. And that's how you distinguish it. So it seems like we should be less anxious than in the past now that most of us don't have to worry about, you know, I'm definitely not going to wander and see a lion in front of me. I'm very unlikely to have to worry about starving to death. It feels like there are all those things in the past that you'd have a good reason to feel anxious like every day all the time. Is there less anxiety now than there was a few hundred years ago? So I think we have to compare it in the more recent times and I'll tell you why. Anxiety has actually always been the most common condition in the world, specifically in the United States.
6:36But depression is more disabling for people, and that is why people talk about that more often. Often, depression and anxiety run together. But despite all of that, anxiety increased by 25 % after the pandemic worldwide. Uma, I just want to confirm, you said it's gone up 25 % since COVID just a few years ago. Yes, 25%. And this was published in The Lancet. And so if you have a friend, family member, colleague, spouse, friend, whoever it might be that's feeling anxious, or you're just noticing it when you go to buy your cup of coffee, it's real. And I feel like that really is what I've been seeing in my practice over the last several years, a real spike in individuals who didn't have anxiety before, who are wondering where this is coming from, developing it at a later stage in life sometimes.
7:28times. And I think it's therefore pretty serious and one of the epidemics in the world that is not being addressed. While mental health is in crisis, some of it is driven by that level of angst and anxiety that everyone is living with. If you're a regular listener to this podcast, you've probably heard me and many of our guests talk about eating 30 plants a week. You may have also heard me talk about Daily 30, Zoe's gut supplement crafted from over 30 plants to support digestion, gut health, and energy. Our gut health scientists developed this supplement to make it easy for you to get over 30 plants in your diet.
8:05Simply sprinkle it on any meal. I begin each day by adding it to Greek yogurt and berries, but many Zoe members tell me they love it on eggs and avocado toast, in fact, a wide variety of meals. And when you scoop daily 30, you can actually see that you're eating real plants. And that's because it isn't a bunch of chemicals reduced to a powder. It's a supplement of 30 scientifically selected plants that carefully retain their cell matrix. As I discussed in a previous episode, when Zoe was first developing Daily30, we ran a randomized controlled trial to see whether a whole new class of supplements could actually work.
8:41And the results exceeded our expectations and helped us create the formulation that we sell today, one that we're continuously refining and iterating. By the way, whenever we talk about Daily 30 as a good source of fiber, we're required to say that it contains four grams of total fat per serving. Obviously, that's all amazing healthy fats from plants. If you tune in regularly, you know what we think about this focus on single chemicals. But honestly, we prefer to let the benefits of Daily 30 speak for themselves. Ready to improve your week? All it takes is a scoop to make every day a good gut day.
9:17Just go to zoe.com slash daily30 to start adding it to your meals. Right now, we're offering our listeners a free Zoe tin and magnetic scoop with every order. So order yours today at zoe.com slash daily30. I feel we often talk about being stressed a lot and I definitely feel that I have a lot of stress at work? Is there a difference between like, I feel quite stressed or like I've got a stressful job that I'm thinking about and anxiety? Yeah. I think of anxiety as more clinical. Okay. Meaning that the symptoms we talked about and then those diagnostic criteria, whereas stress is sometimes used more widely to describe more of a state of mind.
10:02Stress related to my job, travel, commuting, something like that. Whereas anxiety may be much more intrinsic to how you're feeling and carrying that. But stress and anxiety also linked. For example, people talk about stress eating all the time and those things are linked. Can you tell me what's going on in the brain with somebody who's living with this anxiety? Yeah. So the flashpoint of anxiety in the brain is a region called the amygdala. Now we know from the study of the microbiome and study of the gut and the brain that the gut and brain are connected. And it starts with the fact that the gut and brain originate from the exact same cells in the embryonic cell line and then develop into two separate organs that are different parts of the body, but they remain connected by the 10th cranial nerve, the vagus nerve.
10:55And the vagus nerve is really a two-way transmitter for text messages. And these text messages are actually in the form of neurotransmitters between the brain and gut and the gut and brain, it's bidirectional. So the flashpoint for anxiety is this region in the brain. And it might be that you had a very stressful day at work and you were anxious or you had an uncomfortable or worrying situation with your boss and your gut microbes are starting to evolve and change in response to that stress. It might be that that caused you because of what was going on at work in the last week or longer to be ordering junk food at work instead of ordering a healthy salad, getting takeout and eating that consistently.
11:42Maybe you went out with your friends and instead of, you know, usually having a glass of wine once a week at dinner, you're having one to two glasses of wine, maybe a beer every night because of the situation that's happening. So you find over time this buildup of anxiety and that is of course unrelated to everything else that might be going on in your body. But I'm looking at it from the angle of food, nutrition, and how this might be impacting your behavior. So I love this idea. You're saying that like my gut and my brain, when I was a tiny embryo, were like the same thing. And then they separated out, but they sort of stayed in touch.
12:19I think that's brilliant. I've never heard that before. And I think you've also made clear that the amount of anxiety, people living with anxiety has been growing a lot. I'd love to turn now to like how nutrition is fitting into that because I think a lot of people listening to this episode will be quite surprised that then you're saying that the food you eat would affect this because I think many of them like me will naturally have gone to, well, it's really the stress of modern life in the sense of the job and the phone and whatever else. It could be aspects of that too, but it's also food. And that's the part that often gets ignored.
13:02So why does nutrition impact our mental health? It goes back to one of the mechanisms being that gut-brain connection. The fact that neurotransmitters are communicating and the fact that the food we eat is being digested and interacting with the microbes in our gut. And Uma, can you help me to understand a bit more about how these gut bacteria can be having any effect on the brain? Because I know you've mentioned one or two that there's some link, but what's actually going on? They feel like they're a long way away from each other. Gut bacteria are really small. What's going on and how real is this science?
13:40Is this like your own very hypothesis-driven view or is there real science behind what you're describing? Yeah, so there's real science behind it, and it's been researched, it's been studied, and it is evolving science. Nutritional psychiatry, and certainly when I practice nutritional lifestyle and metabolic psychiatry, is an evolving science. It's nascent, and there's new evolving evidence every single day. But what we do know is that the trillions of microbes that live in our microbiome and our gut, as they're helping with the process of digesting our food, their breakdown products are also in the same environment as 90 to 95 % of serotonin receptors.
14:22Now serotonin is often called the happiness hormone. There's serotonin in the brain and other parts, but there's 90 to 95 % of the receptors in serotonin production happens in the gut. So the linkage that I make that's been backed up by science is that as our food is being digested, It's also in the same environment as where these neurotransmitters are being produced, where the receptors are located. So we are therefore really understanding more and more that mental health is not this impact of just the brain. It's the brain in connection with the gut and other parts of the body. And can you explain a little bit more like what is a serotonin receptor?
15:04And if it's in my gut, how's that linked to my brain? and how does that then make me feel different? I think I was brought up, you know, sort of stiff upper lip, like whatever happens in the outside body shouldn't really affect how you feel. I think that the science doesn't really seem to support this as much. What is going on? So I think the best way to think about it is in this way. The microbes, the microbiome is associated and anatomically, physiologically, and biochemically connected to the brain through the vagus nerve, through the enteric nervous system, and through the transmission of these neurotransmitters.
15:46So serotonin exists in more than one place. When I said serotonin is the happiness hormone, medications like selective serotonin reuptake inhibitors or SSRIs are the medications that are used to treat conditions like depression and anxiety, but they also manipulate serotonin. So think about it this way. serotonin is involved in conditions like depression, anxiety, and more. It's first-line medication in mental health that people are prescribed, but food is also involved. And food is involved because it's being digested in the same place where the serotonin is being stored, manufactured, and the receptors are located.
16:25And it therefore can mediate emotion through how those interactions happen as food is being digested. For example, if you are mostly eating ultra-processed foods and sort of a poor diet, not only the breakdown products of that food are really going to lead to conditions like inflammation in your gut. And studies of inflammation in actually a big UK Biobank study of more than 144 ,000 participants showed that participants who had anxiety and depression also had increased markers. And these markers were inflammatory markers, interleukin-6 and C-reactive protein. So we know that inflammation is also involved.
17:10I want people to understand that there's this gut-brain connection, there's the mechanism for how food is being digested. Serotonin is right there, as well as other neurotransmitters in that environment. Another neurotransmitter, for example, is GABA. And GABA is associated it's an inhibitory neurotransmitter. It's also associated with anxiety. It's associated with the hippocampus. It's associated with the brain. Well, we found in a research study that a certain type of bacteria is associated with GABA production. And this type of bacteria's name is Bifidobacterium adalocentis. And when the production, for whatever reason, of that bacterium is low, GABA is low, and anxiety is high.
17:58So there's all of these different connections. I mentioned serotonin because of those receptors, but there are also these other neurotransmitters. And it's a more complex way to understand that anxiety is not just one thing, that the food you eat can impact these microbes and can thereby over time, not always immediate, can impact your anxiety. Let me play about what I think I'm understanding, because this is definitely quite complicated. The bacteria in our gut are creating these chemicals and they're then interacting with our own cells that are in our gut wall, which are available. You mentioned the thing like serotonin, but some other neurotransmitters.
18:44And then somehow this is sending a signal up to my brain that is then changing what's going on in my brain. Is that right? How does that work? So the neurotransmitters are transmitted via the vagus nerve, which is the 10th cranial nerve, which is going directly to your brain. So there's a nerve from my brain to my gut, like there are nerves to my fingers that I'm flexing right now. Exactly. And it turns out that the vagus nerve, another name for it is the wandering nerve. It goes to so many places in the body, but it is actually a direct anatomical connection between the brain and the gut itself.
19:19it gets to my brain. Why does this change how I feel? How's that making me anxious? What's going on in my brain? Can you see a difference between someone who's living with anxiety versus someone who's not? Is that something you can actually see in the brain? I'm not sure that we can see it in the brain, but we have the serotonin hypothesis that has lasted for many years. And a couple of years ago, a very important study published in a British journal actually upended that hypothesis and kind of questioned it, which I think was very interesting, showing us again, that we're not 100 % certain in mental health of some of these pathways, but we work with what we know.
19:57In other words, mental health is never a tissue diagnosis. And what do I mean by that? If you have a cough and a chest infection or pneumonia, your doctor will probably ask you to cough up into a cup, draw some blood tests and make a diagnosis. In mental health, we don't have that. We don't have a brain biopsy that will diagnose something. We have always used these diagnostic criteria that are based on a lot of information that we've put together for these manuals. So I don't want to imply that it's soft science because it's not. Mental health is very real and conditions need treatment. And the medications that have been designed do help that.
20:33But I'm using it as a lens to explain that a medication like an SSRI, like Zoloft or Prozac, exotrin or fluoxetine, the other names, will actually impact those serotonin receptors and change the levels of serotonin in your brain to actually make you either feel better. On a separate note, those medications don't always work. So we clearly need more solutions to help people. I've got it. So I think what you're saying is, firstly, there isn't just like a blood test or something like this where you can figure out a level of anxiety. It doesn't mean that it's not a real diagnosis, but scientists haven't developed a way to sort of measure this in like this just single test.
21:13And that this role that you've been describing is that the bacteria are then really interacting with these receptors in our gut and then they're sending these signals on these nodes to the brain and this is shaping us. And that the very targets that you're describing for the drugs that we've heard of, like Prozac is definitely one I suspect most listeners like me have heard of before. or it's like the same thing that these bacteria are influencing? The bacteria are influencing all of this as well. And the bacteria are impacted. One of the things that impacts, and we mentioned stress earlier, but they're also impacted by the food that we eat.
21:48And that's where food can become something that we can alter to improve how we're feeling emotionally. And I want to come on to that. But just before I do that, I just wonder, is there also something that goes the other way around, which I think you talked about in your book that I thought was really interesting. So can stress affect the bacteria in your gut? Yes. So you may not notice it immediately, but research has shown that, say you have that stressful day at work, an argument with your spouse or partner, the gut bacteria actually respond within a very short time and start to evolve and change.
22:22Not in a good way, because stress does not impact them in a good way. When we're stressed, our cortisol levels go up. It impacts many of our different hormonal systems in the body. and it actually can lead to heightened anxiety. So understanding that the gut microbes are responding all of the time and we want them to really work for us, not against us. And Uma, how fast will my gut bacteria change if I've had that sort of row with my wife this morning? Yeah, so some of the research has shown within two hours, they start to evolve and change. Now, does that mean they produce anxiety? No, not in the immediate two hours, But over time, if a stressful situation persists, they do start to evolve and change further.
23:06And they start to react almost immediately. And is this one of the ways that being under stress for a long time can make you anxious, that it could actually change? It is definitely one of the ways. Can I ask a different question since I've got a world expert here, which I'm really interested in? I think lots of people, and I feel the same way, say, you know, when I'm feeling really stressed and anxious, like I sort of crave unhealthy food in a way that, you know, when I'm feeling calmer, I don't. Is that a real thing? And what's going on? It is a real thing. I'm always going to say there are more than one mechanism because there are.
23:39And I also want to make sure we understand science is evolving. I'm never 100 % certain about one thing at one time, but we follow what that says. And that helps us treat people clinically. But stress actually precipitates habits circuits in the brain, meaning that when you're stressed, you might choose unhealthy foods and you might enjoy that food. And the next day you decide, let me order that again. And it's still an unhealthy food, right? But that stress actually precipitates those habit pathways or circles in the brain. So when someone says to me, I'm stressed and I'm eating poorly, or I have stress eating, they may be using a term that we sort of an everyday term, but it actually has some science behind it.
24:23When that happens, you just continue along a path that you continue eating those unhealthy foods. And it's very hard for people to break that cycle. There's a real reason that your brain is acting that way. And some foods like highly sugared foods, things like high fructose, corn syrup, actual sugars. I'm not talking necessarily about healthy versions of sugar because you always want to have a couple of servings of fruit. Talking about really eating candy and cookies and cake all the time. Research has shown that sugar impacts dopamine reward pathways in the brain in a similar way to street drugs like cocaine.
25:04So when people talk about sugar addiction, it may be a strong term, but they're actually describing how they're feeling and they cannot step away from sugar. So that's real too. I mean, I have to follow up on that But for a minute, when you're saying you can be drinking a sugary drink and it could have a similar impact to cocaine, could you explain a bit more what's going on there? So cocaine is a street drug that will tap into the dopamine reward pathway, another neurotransmitter in the brain. And it kicks into certain behaviors and it makes you feel a certain way. And it also makes you feel, because of the reward system, makes you feel good, so you want more of it.
25:44Sugar does a similar thing. It makes you feel good in the short term. The long-term impacts of sugar on neurons in the brain or the brain cells is not good. But in that short term, people feel great. They have that little feeling after they eat sugar, but then they can't step away from it. They want more and more. When people say they're addicted to sugar, it is a strong term, but it is a real feeling that people feel where I cannot not have my bag of candy or my two chocolate bars after lunch or something like that. And when you say addicted is a strong term, but they do want it, could you just help me to unpack that a bit more?
26:20Sure. All I mean is sometimes scientists say, well, oh, you know, addiction is such a strong term for sugar, because maybe it's just that someone cannot, just is eating too much sugar. But I see individuals who literally, you know, cannot live without it. Now we need, understand that we need sugar in our bodies. It's part of a normal healthy diet, but it's where we obtain our sugar from. That's critical. You know, we don't want our sugar from high fructose corn syrup and added sugars. And the 262 other names for sugars that I found on U.S. food labels are not the sugars that we want because they're hidden sugars.
Read the full transcript
26:56And when we consume them, we get used to them and they taste good. And in the short term, they make people feel good. So they continue to want to do that behavior. So there is like a real thing, which is like, I'm feeling down or anxious. I'm not even talking about somebody who meets your definitions of like a clinical condition that actually like eating a sugary donut or a Coca-Cola with sugar, whatever, that's literally going to trigger something in my brain that's going to give me like a little temporary blip of positivity. Like that is real. And then what I think you're saying is that sort of creates this feedback loop, I get a crash shortly afterwards this, and then I'm like, oh, well, I want to have this again.
27:39So I'm sort of trying to... People don't forget the crash. And they also don't realize what's happening to their insulin and their blood sugar, but they do feel that sort of emotional crash. And then like, well, have you ever wondered why they sell two doughnuts at a time? Well, my theory is that, you know, you have the first doughnut and you experience that and you need that second doughnut. Because you have the high and then the crash from your blood sugar You need another one. And then you need another. And you're not satiated. It's not food that's filling and fiber-filled and nutritious. It's just laid more sugar.
28:10It's really interesting. But you're saying that actually there is this real thing when you're under, you know, if you're anxious, whether you're under stress, it sort of pulls you into this. But then, I mean, your analogy with cocaine is obviously strong. But we all know that if you are feeling stressed, that cocaine is not a good solution to this problem. I don't think anyone listening to this, even anyone who might be using it is going to say, I know it's like, nobody thinks it's a good solution to this. So just to be clear, the connection between sugar and cocaine is this particular research looked at the fact that cocaine tapped into this dopamine reward pathway or reward loop in the same way that sugar does.
28:47What is a dopamine reward loop? So dopamine is a neurotransmitter. And when people use cocaine, it makes them feel good and they want more. Very simply, this research looked at sugar and sugar does the same thing. Makes you feel good, like that donut, and then you want more. So I take it very seriously when people say, you know, I really just can't give up sugar. And I think it's really not about giving it up completely. It's about finding healthy sources and healthy amounts of sugar that you eat. That's fascinating. and I think we just started about like, does stress and anxiety make us crave unhealthy food?
29:27And it sounds like it's in a sense, this stuff that's out there does have this amazing short-term impact on us. And I guess the stress and anxiety is like, it's harder to resist and also like that little buzz that you get, like feels particularly rewarding when you're feeling a bit down. Yes, it does feel rewarding. It's short-lived. Then you might reach out for more or you might not feel good, feel a little bit down, feel more anxious. And it really does create almost a very uncomfortable loop So I can definitely see this pathway where you can get pulled into the ultra-processed food that we're surrounded by.
29:57Just before we talk about switch to, I think, a really positive thing about what are all the things you can do, I just wanted to ask, are there health risks associated with living with chronic stress and anxiety? It's obviously what you're describing as very uncomfortable for how you're feeling. Does it also affect your body and your health? Yes. One of the things that we haven't really touched on is the fact that this is a very integrated and holistic approach to helping people, right? We need to understand that, like I said a few times, the brain and the rest of the body are all connected. Without the brain functioning, the rest of the body cannot work.
30:35So it is, in fact, most important organ in the body. When we are so stressed and anxious, we are doing things that are happening in our body include a heightened cortisol level, heightened level of stress. People may have an impact on metabolism because they are stressed. They may be eating poorly. That may lead to things like leptin resistance over time, which impacts their metabolism. So leptin is the hormone that tells us that before, and eat a plate of food, put it down, put your knife and fork down, and you drink a glass of water and you're done. When you develop leptin resistance, one of the reasons could be extreme stress, you don't feel satiated.
31:17You want a second plate of food. You want cookies after dinner. So I just want to make sure I've got this. You're saying if you're like having long-term stress or anxiety, there's like something you can measure in your body that means you're not able to feel full in the same way. And therefore you're actually going to eat more because it's actually changed the biology of what's going on inside you. So where it's associated with where anxiety and metabolism are associated and where metabolism in our body, which is also associated with mental health. It's a connection that we're really understanding better now.
31:49And the link I'm trying to make is that when we have this chronic persistent stress, one of the ways that it impacts through the lens of nutrition is how we eat. Because if we start to eat poorly over time, it can affect what we call our hunger hormones, and they stop functioning properly. They stop telling us that we're full, that we should stop eating and have a glass of water and maybe watch a television show or take a walk after dinner. It does the opposite. It's, well, I need another plate of food and then I want a dessert. And after dessert, I want a snack. And this is when people start to develop leptin resistance.
32:28So it's one of the consequences of stress through the lens of food. I mean, but this is real science. Like we've really been able to see this change in the leptin resistance that you're talking about? Yes. So leptin resistance can develop. Your metabolism is impacted. Cortisol levels are affected. You may start to gain weight. You may not be able to sleep well. You start to experience more anxiety, all of that. I'd love to switch to like, what are the actionable tips that can help our listeners to gain more control over their mental health? And since this is Zoe Science Nutrition, I'm bound to start by asking about food.
33:03how can we use food to calm our minds? So I would like to answer that question by saying that food is one of the pillars of helping conditions like anxiety, mood disorders, and more. But it is also in conjunction with practices like yoga, meditation, shonyoku or forest bathing, in other words, being close to nature. Maybe it's learning a breathwork exercise. Maybe you like to do Tai Chi, some type of movement, many, many different things. Also things like hydration. Keeping adequately hydrated is critical for really not feeling anxious because dehydration can lead to anxiety. We've talked about the mechanisms and some of the mechanisms, but the way that food can calm the mind is through the selections that we make.
33:56When we're eating fiber-rich, plant-rich diets with healthy fats and healthy proteins from clean sources, we are feeding our body with nutrient-dense foods that are antioxidant-rich, rich in anti-inflammatory substances. You've heard the expression, you know, the color of the rainbow. I like to call it sort of a kaleidoscope of color because it's so many brilliant and beautiful colors. And it represents so many different antioxidants and polyphenols from plants that represent positive substances we are feeding those gut microbes with. And Uma, can you help us understand a bit what happens as you change to this food?
34:36What's going on with these bacteria? And then how does that flow through in a positive way? So I think you've talked a lot about the bad things that could happen. Within these trillions of microbes that live in the gut microbiome, they're the good guys and the bad guys. When we are feeding bad guys, that leads to inflammation. we talked about gut damage, gut lining damage, hyperpermeability or intestinal permeability, that type of stuff, or leaky gut. But when we're feeding the good guys, they are thriving, they're being fed, they're helping us, they break down products called short-chain fatty acids, which take care of the gut, help healing of the gut.
35:12And the moment we start to switch to healthier foods, people will start to notice changes. Sometimes they just notice their sleep starts to improve. Sleep is related to anxiety, or they notice that they don't get up with that horrible pit in their stomach, feeling so anxious about getting to go to work that day. And how fast in your practice when you see people, do you start to see this improvement? Are you seeing that people are waiting, is it years after they start to make these dietary changes that they start to see an impact? Fortunately, it's sooner than that. I have individuals call me within a week to say their sleep is starting to improve.
35:50They're not cured. That would be the wrong term, but they're starting to feel better and they feel much more positive and they want to do more of these nutritional kind of therapies and nutritional treatment plan. But sometimes it's up to like one to three weeks where they really start to notice that they're less anxious. They're waking up better. They're sleeping better. When they're eating healthier, they're satiated or they've eaten a plate of food and they're full. Whereas if they had gotten takeout or other foods, they want more than one bag of fries or whatever it might be that was sort of driving that.
36:25And so they start to feel better. I was thinking, Uma, if you told me that even two years ago, I think I would have been completely shocked. And what's changed between now and then is we at Zoe have something called Zoe Membership, which is our personalized nutrition program. And we ran a full randomized control trial of that that was published in Nature Medicine a few months ago. And so we looked at the outcome of people going through Zoe Membership compared to people following sort of the standard advice in the States. And we got them to report out not just on sort of blood work and waist circumference and things like that, but also on sort of energy and hunger and mood.
37:03And what was totally amazing was we saw these really big improvements in people reporting things about sleep and about mood. And I never would have expected it because it wasn't when the scientists were originally sort of designing this program, it was very much focused on sort of long-term health and improving the microbiome. It wasn't at all thinking about mood or sleep, but there's like these really big statistical changes, which I was shocked by. And so now hearing you talk about this, it sounds as though in a way you're not surprised about that. I'm not because I've seen it in clinical practice for a while.
37:41And I'm grateful that more studies are proving it, like the studies that you all performed. And I also think that science is exciting and evolving, especially around the areas that you all work on at Zoe, because there's this research lab at Harvard associated with Beth Israel Deaconess Medical Center that published the study earlier in September of 2024, where they are looking at a gut first approach for conditions like Parkinson's. So they did a cohort study on, I think it was just over 9 ,000 patients and found that those that had mucosal, so that's the lining of the upper GI tract, that was damaged or problematic, and that can be caused by taking medications like NSAIDs.
38:32Examples are ibuprofen, or it could be GERD, gastroesophageal reflux disease. It could be ulcers from things like H. pylori that can cause damage. They were 76 % more prone to developing a clinical diagnosis of Parkinson's. So by looking at a gut-first approach, all I'm speaking to is sort of the power of the microbiome, they're wondering about where does Parkinson's really originate? We'd always thought it was more of a brain-based disease. But when we look at patients who develop Parkinson's disease early on, they have gut symptoms. They might have nausea, they might have constipation and discomfort in their gut.
39:14And it's often happens many, many years, even more than a decade before the actual diagnosis that has more of a neurological, psychological feel to it, the symptoms that show up. So, you know, it's fascinating work. That's amazing. So you're saying, this is obviously very early science. Yes. It's really exciting that you're sharing with it, that they're actually saying that there might actually be a link, you know, it's issues that are starting in your gut, turning into Parkinson's, you know, maybe 10 years later. And I guess another example of the link you're describing between the gut and the brain.
39:46Correct. Exactly. I think we have to follow the science and we also have to be humble about it because it does change and evolve all the time. Like I think the research done in the UK that in to some extent upended some of the serotonin hypothesis of conditions like depression was very compelling. But that doesn't mean you should stop taking Prozac. It means you should have a discussion with your doctor. And it sounds like there's in fact, from the way you described that, there's a lot we don't understand about how mental health works. There's a lot we don't understand. And to me, that was something that really pushed me in the direction of nutrition.
40:22Not only did I feel compelled to find more solutions for my patients, I felt that it was a stone we'd been leaving unturned. We were prescribing all these heavy hitting medications that in fact had side effects like weight gain or other problems, but we were not really addressing real lifestyle and diet, you know, so other than a checkbox collecting someone's weight and height. We were not really asking about what they were doing that could help them with food. And Uma, if someone's listening to this now, they're saying like, I'm sold, I want to make changes, I am living with anxiety, or even if it's not clinically diagnosed, like I feel like I have a lot of anxiety in my life.
41:01What is the sort of specific advice you would give thinking about food to someone who wants to make changes that would maximize the benefit? If I could just also add to what you said, as I answered the question, that it may not be that you have a diagnosis, but you're feeling this way. And this is a very powerful tool that can help you. Food is one of the things that can help you, including things like breathwork exercise, exercise itself, and other things. Even sunlight are important. So I have three steps that I ask people to take, and I have the mnemonic SOAR, S-A-W. So the one is SWAP. So SWAP, one unhealthy food to get started.
41:39So maybe you started eating ice cream every night during the pandemic. Can you create a recipe that I have, for example, for ice cream made from fruit and swap that out? Or can you start to eat less of it? So the first thing is swap. Swap at least one unhealthy food habit that you have. It may be that you're not drinking enough water. It could be that. The second is add. So add in healthy, add in a healthy food. An easy way to start is adding in lots more vegetables, colorful vegetables to your diet. Things like colorful peppers, lettuces, greens, spinach, whatever it is you might like. Adding those in are low calorie.
42:18So cruciferous vegetables like cauliflower and broccoli and Brussels sprouts, low calorie, and can be added in to your meals that are both going to help you feel full, but they're also giving your body nutrients and antioxidants and anti-inflammatory substances that your body and your brain need. And the third W is walk. And by walk, I mean movement, exercise, a Zumba class, a yoga class, whatever appeals to you to get you going. Because remember, through the lens of mental health, someone who's anxious may not even want to take a walk. So getting them to take a walk, to buy the newspaper, get a cup of coffee, walk their dog is a way to get them moving and move from that almost paralyzed state of feeling so anxious.
43:03We have a lot of podcasts that talk about exercise and people have been sharing amazing impact. Scientists can talk about amazing impact on health. But does exercise have any impact on your mental health? It does. There's a whole body of research on exercise and mental health. Improving mood, depression. For one simple thing, if you've ever had the experience of running on the treadmill and you say maybe you were really pushing yourself, you didn't feel motivated that day and you spent half an hour on the treadmill and you feel really good after that, you're calling your friends to say, what a great day it is, that's often because of the release of endorphins in your body.
43:38So beyond that, there's a lot more evidence to show that exercise helps mental health, improves depression, lowers anxiety. Some of my clients will say they get on a treadmill for 20 minutes if they feel anxious or do some form of exercise because it almost inhibits the anxiety and it kind of catches it because it distracts them and it gives them something else to do when they're so warped or wrapped up in that anxious moment. I try and work out three times a week because I've been sold about the benefit of my health. But I often tell my trainer, I definitely get no endorphins during the session, but I feel like I get a lot at the end after I feel really good that I've done it.
44:11That's exactly right. At the end of the hour, whatever amount of time, you know, you feel sort of good. And it's like, oh, part of it is the accomplishment of doing it. But also it's the way your body is responding. There really is something real. It's not just about long-term health. I can actually affect my mood with it as well. It can affect your mood. So it's an important, that's why I had, you know, the W in for whatever movement it might be that you're doing that helps you. I'd love to talk about people feeling anxious about their diet and how they can avoid that. And I think it's particularly relevant on this podcast, like most of the long-term listeners to this podcast will be Zoe members.
44:45They'll have been paying for this personalized nutrition program that helps them to feel better and be healthier. And one of the things that we've discovered is that we have to spend a lot of time and effort trying to sort of retrain people because they've been told that lots and lots of foods are off limits, that like these foods are bad and that sort of if they want to improve, it's all about sort of restriction, like calorie restriction, removing bad foods. And the way that Zoe membership works, it's really all about focusing on adding things to their diet to be healthier. There's no calorie count, all of this.
45:20And also, one of the core ideas, which comes from a lot of nutritionists who've been involved in it, is that no food is off limits. But what we find is that lots of people are still feeling really anxious about this, even if they've been on the program for quite a while and they're feeling much better. I guess, what's going on around that anxiety about diet? And do you have any advice to anybody listening about how they can reduce that? Well, I'll speak from the perspective of where I live in the US, which is that we have a very eat this, not that mentality, which I argue against as often as I can so that people feel they can embrace all foods.
45:58Maybe it's the quality and quantity of the food, the source of the food that becomes important. We talked about sugar earlier on, eating some berries or a clementine, a mandarin. These are healthy choices as part of not only a fruit serving, but the fiber and other nutrients have faith that you're on the right path to trying to make things better. It may not be perfect, but you are trying to work on consistency, which is one of the biggest things that will help you. Discipline around your food will help you. The moment that someone starts to feel better, they want to do more of those healthy habits and that you can build on.
46:39If you're feeling anxious about the plan, maybe checking in with your nutrition counselor about it. What's driving that anxiety? Is it the quantity of food? Are you maybe not drinking enough water? Are you maybe eating something? Here's a common mistake that people make. I shouldn't say it's a mistake. It's more that they don't realize, for example, yogurt, rich in probiotics, great food, blueberries, delicious fruit, great source of fiber and anthocyanins, good for your diet. Fruited yogurt, so the fruit in the yogurt, not a good idea, because in the United States, a small half cup serving can have six to eight teaspoons of added sugar.
47:18So often someone might be eating something they think and have heard and read is healthy, but the food industry is not necessarily our friend and is labeling food in a way that you think it's healthy, but it's not because of those added sugars. A simple swap would be plain yogurt with berries and a sprinkle of cinnamon. It's super delicious. You get all the benefits from every ingredient, including the cinnamon. So those types of things may be worth discussing with your counselor or whoever you speak to, to check in about what's driving that anxiety. Or maybe it's that you have too much or too little food in your plan.
48:00It could be many different things. I always take it back to when we were first born. What happens when a baby is born? So if you've ever seen it on television or you work in the ER or the labor and delivery, you know that you want the baby to cry. They take a deep breath. And what happens next? Yeah, they clean them up and all of that, but they feed. So think about food as something very primitive. It's very primary to who we are as humans. And I think that when sometimes we're in situations where you can't eat this or there's a media report that you shouldn't eat that, it really drives anxiety.
48:36Food anxiety is a very big thing. And I feel like, understand you're on a healthy path. Remember, so swap, add, walk. Think about calming foods because I have an acronym, calming, and I also add in foods based on that. So very quickly, C is for choline. Choline is in eggs and legumes. A is for something like antioxidants. L is for liquids. Calming teas like passion flour or chamomile, liquid water, very important. And M is more omegas and magnesium. So many more foods on every letter of the list, but just very quickly think about foods you can start to add that help that anxiety. So if you're on the plan and you're worried about the plan, ask yourself why.
49:24Maybe it's something related to questions you have that are not answered or information you need, but you can also add in foods that could help you even more. Uma, I want to just go through that again, just a little bit more slowly, because it sounded great. You're saying like, for people who are having this anxiety, which might be also anxiety about their list, you had this acronym CALM. Could you just talk me through? It's actually CALMING, but I'm going to share CALM with you in the interest of time. C is choline. Choline is a substance, an important nutrient found in eggs, but it's also found in legumes.
49:58I also think of C, two other Cs, extra dark natural chocolate, great source of magnesium, fiber, and serotonin, believe it or not. So extra dark, we're not talking about candy bars, we're talking about extra dark natural chocolate. And another C is vitamin C. A fun fact is that natural chocolate in that way is the highest source of plant-based iron. You usually get iron in meats. But I can get iron in my dark chocolate? You can get it in your dark chocolate. As anyone who's a regular listener to this will know, I'm completely addicted to dark chocolate. So I love that you're giving me, I think, iron.
50:35And did you say I get serotonin from it as well? So now I know why I'm addicted to it. So this really is my cocaine, is that? Sometimes it takes a while for people to get used to that extra dark version, but it's worth it. But here's the kicker. If you have the extra dark chocolate with a piece of citrus fruit, like a mandarin or clementine, it helps the absorption, the vitamin C helps the absorption of that iron. So always pair that together. And by the way, I happened to learn that in culinary school and I didn't know there was, I think they were really teaching it to us because of flavor, the flavor profile of dark chocolate with citrus, but it actually has some science behind it, which I thought was That's amazing.
51:12So if you pair, and I know we haven't managed to get into the fact that you were trained as a chef, but you're saying if I pair the dark chocolate with like some sort of A citrus fruit. It not only tastes good, you're saying, but actually somehow it unlocks the iron better for my body. It helps, that's right. So we were on sea of calm. Tell me about the other three. A is both ashwagandha, one of my favorite supplements for anxiety. It's very bitter tasting, so it's worth looking into a clean supplement or antioxidants. Think colorful vegetables that we've talked about, colors of the rainbow. All of those really bring you the antioxidants we need, but so do spices, spices and herbs.
51:49L is for liquid. So I want people to remember, the reason I put liquid in is water, just plain water is an important part of that. Hydration is really helpful for anxiety or keeping well hydrated, I should say. And other things like a calming tea that you like could be good too. Do you know someone living with anxiety? Why not share this episode with them right now? Uma's practical advice based on the very latest science could really make a difference. I'm sure they'll thank you. Anuma, is that true? Like can a tea, can that actually affect your anxiety? Yes, it can. Passionflower tea, green tea, all of these actually have some science behind them.
52:33So just having or sipping on that calming tea not only helps you, but it's hydrating and it's calming. And M is for a lot of Americans alone, magnesium. And so I want to remind people to maybe talk to their doctors about getting the magnesium level checked if they're suffering with anxiety. And also the other M is more omega-3s because these are important to get from things like salmon or plant-based sources from hemp seeds and flax seeds. Brilliant. Uma, I have so many more questions. We're sort of out of time, so I want to finish with one last one. So you've already just mentioned that you're also a professional chef on top of everything else, which sounds like a high bar if you have any children to keep up with any of this.
53:18To end with, can you share with all of the listeners here one of your favorite ways to maybe eat some of this food that is really good for you and good for your anxiety, but also tastes great? So I love to talk about, and I designed these four forms. This is the fun part of my consultation, design a nutritional psychiatry treatment plan, but a nutritional psychiatry plate. and the anti-anxiety plate is based on a list of anti-anxiety foods and a list of the anti-anxiety protocol that I designed that matches up with recipes. So one of my favorites is a simple plate. I think about it this way. Half of my plate has leafy greens and colorful vegetables.
54:03Maybe it's steamed spinach with good flavorings and a lovely salad along with that. The other component is a healthy fat. I might have some sliced avocado or I have an olive oil dressing in my salad. Another way to get the fat, nuts and seeds always. For a clean protein, I like things like a baked tofu or even air fried tofu for crispiness or something like a cauliflower steak. But I flavor these with, I'll use a tikka masala. It's a great way to flavor up something like cauliflower steak or chicken, whichever might be your choice. That's one of my favorite meals because it has the components, of course, my glass of water, but it has the components that I need.
54:46And my legumes give me my protein and the tofu added protein, a little bit from cauliflower, but it also is all the vegetables, all the fiber my body needs and not seeds, the healthy fats. And for whole grains, I might do like a small serving of quinoa, which brings me fiber and protein, all good for the gut and kind of all in balance. But really 50 % of that plate is the vegetables. Do you have a recipe of that to share somewhere? Can we link to it in the show notes? Yes. Cauliflower tikka masala is in the recipe section of my book. Fantastic. Well, we will share links on the show notes to the book and also where any listeners can find out more.
55:30I know that you're also sharing some things online, so we'd love to do that. we're coming towards the end. I would like to try and do a quick summary if that's all right. And please correct me where I get it wrong. I mean, I think one of the things you made really clear is that the brain and the body are deeply connected. And so this idea that, you know, suddenly I was brought up with that these are separate just isn't true. That's not what the science shows. And that interestingly, you know, the gut and the brain are like deeply connected. And that seems to be so important for understanding things like anxiety.
56:01You told us about this wonderful dopamine reward loop where I'm now thinking about donuts can be like cocaine. They're literally setting my brain on fire. And then I crash and then I want it again. And we know that's not very good with cocaine. And you're saying you can get the same thing with sugar and these foods that have this very freely available sugar, which is different from sugar that would be inside some fruit. It's all sugar, but it's a healthier source. and comes with that. Doesn't trigger this same environment that you're talking about. You helped to explain what anxiety was and the point, what I understood at least as sort of different from just being stressed is like there are these very physical, specific symptoms about sweaty palms and your heart racing, you know, all the way through to not being able to get out of bed, just sort of thoughts racing.
56:50And that interestingly, you know, if you are under a lot of stress or sort of living with anxiety, it actually triggers like, you know, habits in your brain that can be pushing you to eating this unhealthy food, which is then sort of creating this, I guess, sort of negative spiral if you're eating that food that's changing your microbiome, changing how you feel. And if you live with this for long enough, this stress, it actually means, you know, things like your hunger hormones can stop working. And so there really can be this shift that means that then you're going to, you are going to end up overeating as a result of this stress because of like physical changes that you said that, you know, you can measure in the body.
57:24Then I think you shared a whole bunch of like really specific actionable advice, which I love. One that I remember is SOAR, S-A-W. So swap one unhealthy food for something better. Add a healthy food into your diet and then walk. Because sort of surprisingly, exercise isn't just generally good for your health, but it can actually have an impact on your anxiety. Dehydration can lead to anxiety. I had no idea. So you've talked about liquids a lot. You gave me yet another reason why I can eat dark chocolate after dinner. So it has serotonin and iron. And apparently, I just need to add a slice of orange.
58:01I'm going to get all that iron. Calming tea really does work. I had assumed that that was just something that, you know, the manufacturers were selling to convince us, but it's real. And then finally, maybe just to finished, we talked a bit about people feeling anxious about their diet and getting really worried. And I think what you said is people shouldn't feel that food should be off limits. So even like the donut that you're talking about, you shouldn't feel like you can never have it. I'm glad you said that because if I could just say, you know, if it's your birthday and you want a piece of cake, you really should eat it.
58:33I really am opposed to restrictive diets and clinicians who say you should never eat a slice of pizza. It's about what you eat over the longer term, using these different tools to help you that will help balance out your anxiety, your mood, potentially even your weight because you're eating healthier, rather than, you know, worrying about that particular dessert on your birthday or something like that. I absolutely love that. And I think one of the things that we see with everyone who are Zoe members successfully over time is that they are, you know, able to go step by step and they're able to think more about what they're adding in and less about the stuff being off limits.
59:07And I think the other thing, you know, that you mentioned around this is, you know, you don't need to avoid all sugar. Just try and see, could you be taking it more as fruit and less as Coca-Cola? Have faith you're on the right path to make things better, you said. You don't need to be perfect. Sort of work on consistency. And then finally, to wrap up, I just thought you had this great, really concrete example of how hard it is for people to eat well in the modern world. You said, look, plain yogurt is good. Berries are really good. So berries in plain yogurt is really good for you. But if you go to the supermarket and you buy a fruit yogurt, actually, the manufacturer will have very cleverly built this thing that sounds like it's plain yogurt with berries.
59:48But actually, it's this ultra processed food with loads of added sugar and all sorts of other things. So you're in this environment where it's very easy to end up eating food that turns out to be bad for you and I think can create this sort of spiral that you're talking about. That's right. And, you know, I know the amounts of sugar in the US yogurt. So I just want to point out I was quoting that only because you may have a healthier version where you are. Honestly, it's pretty much the same everywhere around the world. I would think. Uma, thank you so much. I thought that was fascinating. I hope that as you continue to do your research, we can get you to come back again in the future.
1:00:23I would love that. Thank you so much for having me. It's a pleasure. Bye-bye. Bye.

1 in 3 people have anxiety. It’s the most common mental health disorder in the world. And many of us know what anxiety feels like: palms sweating before a job interview, losing your appetite before a looming deadline, a pit in your stomach when you get bad news. It’s not just in your head, it’s in your gut.
Today, we’ll learn how food could help us cope. Our guest explains the rising global trend toward increased anxiety: its rise through the pandemic, and explosion among young people.
