Dr. Uma Naidoo, welcome back to the podcast. It is an absolute honor to have you back and huge congratulations to you on your latest book.
Dr. Uma Naidoo 03:02
Thank you so much, Elizabeth. I'm always happy to speak with you. We always have such fun conversations. So, I'm looking forward to it.
Elizabeth Stein 03:09
Well, I thought we would just dive right in and start with a question to summarize the book. What is the one thing that you want readers to take away from reading your new book, Calm Your Mind With Food if you could only pick one?
Dr. Uma Naidoo 03:26
I would pick one thing it is that we do have the power at the end of our fork to impact the level of anxiety. It's a gap that most people are overlooking, turning to pose two very important forms of therapy and other means. But food is also something that is within our power. And I want people to understand that first and foremost.
Elizabeth Stein 03:50
I love that. Certainly, the mission of the book resonated with me. I know it'll resonate with our community. And as the last couple of years where anxiety has just been on the rise since COVID and we have this mental health epidemic, I would love just to kind of ground us in. Where are we today? What are some of those kind of stats on anxiety? And probably all of that spurned to, I'm sure, inspired you to write the book.
Dr. Uma Naidoo 04:23
So true. Anxiety disorders are the most common mental illness in the world and this has consistently been shown in research. After the COVID-19 pandemic, the level of anxiety disorders has grown from about 298 million people affected to 374 million people, which was in rise of about 25% which is just a huge marker and understandable that when we turn left or right in anyone in our lives, everyone's experience something of a tinge of anxiety with a small, medium, or large, so to speak. But there's a lot to it, as well as that the American Psychological Association shows that three-quarters of adults report symptoms of stress. And this was before COVID. So, they were already reporting that many people are just reporting symptoms of stress. So we can only imagine that has also increased, right? But I also was concerned that about 70% of people, and this has been shown in research with mental illness, have no treatment from an actual healthcare provider, and don't have access, so perhaps the stigma associated with it, but they're not necessarily getting treatment. I think this is where tools like food and nutrition become additional tools in their toolkit to help us through what we know has become, a mental health crisis, but anxiety has become its epidemic of sorts.
Elizabeth Stein 06:01
And would you say that even if you're someone who has identified that you have anxiety, and you are taking medications, or seeing someone eating the wrong foods, I'd imagine, isn't helping and is deterring from perhaps the other path that you're going down with medications and things like that?
Dr. Uma Naidoo 06:26
Absolutely correct. You've heard the expression you can't exercise out of a bad diet. Similarly, it's great you're seeing a provider, and you're taking medication for anxiety. But if you're eating unhealthy foods 100% of the rest of the time, you are not helping yourself. Because what you're doing is you may be taking medication, but the foods that you're eating bring inflammation to your body, especially your gut and your brain, and just setting you up to fail. So cleaning up your diet, no matter what, whether you may be seeing a therapist, or maybe you're taking medication and seeing a therapist, whatever it might be, and the food can always only enhance and improve upon what you're already doing. And it's also, in some cases, a solo treatment, along with more of a holistic and integrated model of care, like exercise, movement, meditation, mindfulness, fresh air, hydration, and that type of thing. So, it's also meant to be something that you can do in combination with other things as well.
Elizabeth Stein 07:33
Now, how do we define anxiety? Is there a great definition that you can share? Sometimes I wonder if am I stressed. Is this anxiety? What is this?
Dr. Uma Naidoo 07:46
Right. Anxiety usually comes out of nowhere. Sometimes when you're stressed, we often may know the source, we are having a difficult workday, or we have a difficult project, or something is going on at home that's stressing us out. But within society, very many people will report just that it comes out of nowhere. It's a feeling of waking up. Of course, there's a clinical definition, as kind of outlined in DSM-5-TR, which is the Diagnostic and Statistical Manual, but I'll give you a working explanation, that people can identify. You wake up with a feeling in your stomach, wake up with a feeling of worry, not even sure what the worry is about. But every day they just wake up worried. Having an increased heart rate, sweaty palms, just feeling so overwhelmingly worried and stressed about something. Very often my patients will say that they can't take a sock lead to something specific, it just comes on. Then of course it’s things like panic, which can be very frightening. The feeling of your heart racing, sweaty palms, just feeling sometimes dizzy, sometimes nauseous. It feels like a physical, physiological change in your body. So I feel that one of the things I want people to know is when you are slowly and steadily working on the nutritional psychiatry plan to clean up your diet and improve, it doesn’t have to be 100% perfect. None of us are perfect. But for the most part, adding in those healthy foods and those gutrich foods that are healthy, that have fiber that is helping nurture your gut microbes, when you're adding in the foods that are helping you, you are fending off oxidative stress and inflammation. So, you are going to be supporting yourself in many more ways, not just in one way. So it's about finding that balance for every one of us.
Elizabeth Stein 09:46
You mentioned an inflammation. In the book, you talk about how anxiety is rooted, and they're all interconnected in our brain, our gut, our immune system, and metabolism. I thought I was familiar with the brain, the gut, the immune system, and the metabolism was an interesting add-on to that, I'd love to dive into each of those, perhaps we start with our gut, and how our gut health and anxiety are connected.
Dr. Uma Naidoo 10:14
Sure. We know that the guts in the brain are connected. And we know that the gut and brain are connected in the embryo. What I mean by that the gut and brain arise with the same cells in the human embryo, then divide apart to form two separate organs, which remain connected by the 10th cranial nerve, the vagus nerve, and that acts as a messaging system, especially for neurotransmitters between these two organs bidirectionally and also allows for that communication that goes on. So the food that we eat, and oftentimes what I'll say to people, what happens when you have a headache? Headache is usually perceived somewhere in your brain or your head, what do you do? And they'll often say, “Wel,l I hope I have a Tylenol in hand, and I take the water, and I swallow. And I sit down.” And I say that then, “Well, what happens? Did you ever think about the fact that you’re just swallowing the pill, but it's working on your neural tissue because it's reducing some pain or whatever the cause of that pain is? In a very similar way, just that simple example is meant to take us to the fact that when we eat food, food is something that may be chewed, swallowed, we digested in our gut, but it also has effects on other parts of the body. One of those parts is the brain and the evolution of the science around the gut microbiome, the gut-brain connection, especially over the last few decades, has helped us understand that. So the foods that we eat are broken down into more positive substances, like short-chain fatty acids, which reduce inflammation and have antioxidant properties. Or if we are choosing water or fast food, processed, ultra-processed diet, those breakdown products are more toxic to the gut, and they feed the negative microbes, and then those microbes thrive, they set up for inflammation and dysbiosis in the gut that leads to damage of the gut lining. So once the gut planning is damaged, these toxins into the circulatory system, and they also reach the brain. It's an ecosystem that we want to understand and has been one of the bases for just improving our mental health or worsening our mental health. We have control over that through the choices we make when we eat. And that's one way to understand how the gut and the brain are connected.
Elizabeth Stein 12:43
What I thought was important in this conversation about the gut is understanding that it's not just the foods that we eat, that are affecting our gut. And therefore, if we have an imbalanced gut, that could lead to anxiety. But on the other side of it, anxiety can lead to poor gut health, right? So it's like a vicious cycle. Am I understanding that correctly?
Dr. Uma Naidoo 13:12
It is a vicious circle because what I often find is, say we don't know the chicken and the egg story. People come to me and they say, “I'm so anxious that all I do is I turn to these ultra-processed foods all the time, I turn to these junk foods and only eat fast food because that's the only thing that suits me.” One of the things to understand is that in the short term, those types of meals may suit someone because they allow for some conversion of serotonin in the brain. But it's a very short-term effect. Unfortunately, since it also increases sugar in the bloodstream and allows for insulin to be involved, the long-term effects are not very good, not only on our metabolism but also on brain cells. So you're right, if I also have people who are unable to control even a glass of wine or other foods that they are craving, often sugar-laden foods, the added sugars from those foods, because they want to feel calmer, they want to calm themselves and they want to soothe themselves, unfortunately, that's just driving the symptoms in the wrong direction.
Elizabeth Stein 14:23
It's fascinating. And also, I just had some gut issues. I had SIBO I was just diagnosed with which was super surprising to me. I'm a very health-conscious eater. So it just made me think if I'm having these issues, how many other people have some unknown gut issue that we don't know about that is perhaps really affecting them mentally? And there's just so much to learn and discover through that.
Dr. Uma Naidoo 15:01
That's exactly right. I'm sorry that you're dealing with that. But you make such an excellent point many of us are walking around with possibly undiagnosed symptoms or an undiagnosed condition. But so much can be worked on through healing the gut because it involves so many conditions. Those gut microbes, the trillions of microbes that reside in the gut microbiome, they take care of many different things. They take care of our immunity, they take care of infection control, they deal with sleep, and circadian rhythm, which is our internal body clock, they deal with vitamin production and hormone production, and mental health. So they have multiple functions that they're involved in. And some of the time, we may unknowingly have a condition that's affecting the gut, which therefore may be affecting other parts of our body. So it's important to check in with the doctor and make sure that we are asking the right questions and getting the right tests done so that we understand what might be going on.
Elizabeth Stein 16:01
For sure, I will say I've been completely gluten-free and dairy-free now for two and a half months. And I have no symptoms, I had bloating symptoms that I didn't realize. And after three weeks, I felt completely better.
Dr. Uma Naidoo 16:20
That's impressive. Good to know that those might have been causing such inflammation for you.
Elizabeth Stein 16:25
Absolutely. So when you think about or when you hear patients coming to you, what are some of the biggest food offenders that you often hear? Particularly, my mind goes to kids. As we think about the rise of kids having anxiety, there are a million external factors, social media, and all of this, but I'm sure there's also the influence of the kids' diets today. They're loaded with sugars and refined flours and lots of gluten and then all those other things. So, what do you see are the biggest offenders when it comes to food anxiety and kids today?
Dr. Uma Naidoo 17:09
I think that for kids, probably the leading one is going to be those added sugars that we don't even realize. Sometimes unsavory foods like pasta sauces, ketchup, or even salad dressings, or just something, the stuff that they're consuming, the cookies, candies, the snack foods. Sometimes savory snack foods also have added sugar for flavoring because a lot of food companies will add bad sugar. They spend a lot of research and development adding sugar to french fries from fast food restaurants that are engineered to be a particular way to tap into our cravings for food. Children are a very vulnerable age group because they reach out for food or go to a vending machine. I know some schools have vending machines, so they are reaching out the snack foods that are just not best for them. It's also ultra-processed industrialized seed oils. Artificial sweeteners are some things labeled low sugar and people think of it as a healthy choice, but they may be loaded with the wrong types of the older artificial sweeteners or some newer ones that have better evidence related to them. And then the wrong types of fats. The trans fats, the hydrogenated fats are often found in those shelf stable cookies and pastries and things that they may be junk for. One of the things to be aware of is eating poorly. Not only is driving anxiety of amping up the sugar in their body, but the amping up the sugar leads to inflammation in the body, gut issues, and inflammation in the brain. But the other thing is that they're not eating just for the 80-20. One of the pillars of nutritional psychiatry is finding consistency and balance. 80% of the time, if they're not trying to or eating more whole foods, they also are setting themselves up for nutritional deficiencies. And it turns out that iron deficiency is pretty common in children. Iron deficiency especially in children and infants, children, teenagers, and adolescents is associated with anxiety. One of the ways that gets set up is if you're just not eating proper foods. Because you get iron from beans, legumes, and healthy whole grains. You can also get it from animal proteins and things like that, altogether from leafy greens and spinach and foods like that. You get iron in a lot of places. But if you're mostly eating a diet of processed foods, you're just not getting those basic nutrients that your body needs. Even with things like magnesium, many of us may be deficient in magnesium, but again, if we are just rushing out for processed foods, that's a problem and they Increase inflammation in the body without even realizing it.
Elizabeth Stein 20:05
So those foods that you just mentioned for kids, I'm sure are also the top foods to avoid for adults as well for anxiety. As you mentioned some of those nutrients, what are some of the if any supplements that you recommend for adults whether helping to strengthen your gut or to supplement if you are someone who has anxiety?
Dr. Uma Naidoo 20:28
Some supplements that I think are worth looking into and discussing with your doctor include things like ashwagandha because there's a good amount of evidence associated with anxiety. It's been used in Ayurvedic traditions for eons. It's bitter tasting so it's better in a pill form and worth speaking to your doctor about something like that. Saffron, while we cook with saffron, it's an expensive spice and we'll use very little when we cook with it. Although it's delicious and worth using, one has a good amount of evidence and clinical trials with supplemental saffron and it helps mood and anxiety. In the supplemental formula, you get enough saffron in that capsule or that supplement. So, that's worth talking to your doctor about. Other ones include vitamin D. In the northeast, a lot of people may be deficient in vitamin D, because of the level of sunshine, worth checking in with your doctor.
Elizabeth Stein 21:24
How much vitamin D do you usually recommend to take?
Dr. Uma Naidoo 21:28
My easy hack for vitamin D is spending 10 minutes outdoor time in daylight, without sunblock or sunscreen, which gives you 80% of your vitamin D for that day. I think every one of us should be doing that. And then of course, apply sunscreen, and use sunblock after the 10 minutes, but not through a window, really spending 10 to 15 minutes outside. But I always go to food first. With the vitamin doses, they usually recommended doses of vitamin D for different age groups. So obviously check it if you're worried about the symptoms, once you have a blood test. The doctor can help you supplement with the right form and the right dosage. My easy hack is food first and also outdoor time.
Elizabeth Stein 22:21
So let's get into food. We know that there's not one approach for everybody. But overall, what is the best diet approach that you recommend to your clients and to the community to manage symptoms of anxiety? And then we'll get into a few of your favorite kinds of all-stars.
Dr. Uma Naidoo 22:43
It's funny because I like to make it easy for people. In the book, I go through an anxiety shopping list. I go through a food protocol and make it actionable after unpacking the science with people. How can they put it to use and why is it that we should pay attention to micronutrients and macronutrients? But rather than give everyone too much information, I have an acronym that I developed called CCCALMS. And what I did is I pulled from the book what I think people should have on their fingertips so that these are things that they're kind of always thinking about, then there are many more foods that they can fall in. So the C is for colors. And by the colors, I mean all those different colors of food, fruits, and vegetables, they bring those different plant polyphenols, which nurture the gut microbes. They bring fiber and carotenoids. They have these different nutrients that are great, and we should be eating them. The other C is vitamin C, and the third C is chocolate. By chocolate, I don't mean candy bars. But I'd like people to know that they can eat extra dark natural chocolate because it's rich by the way, in a plant-based source of iron and very rich in things like magnesium and even serotonin. So really nutrient-dense. Dark chocolate has been shown in studies to improve mood. We know that mood and anxiety run together all the time. So just worth getting into the colors, the dark chocolate, and the vitamin C. Then the A is for anthocyanins and ashwagandha. Anthocyanins bring out a beautiful hue in blueberries but are great for the gut, anti-inflammatory, and antioxidant properties. And then ashwagandha we touched on already, when people remember that there's a choice. And then the L is for your liquids. And by that I mean add your teas. People often overlook the fact that things like lavender tea, passionflower tea, chamomile, and things with turmeric and a pinch of black pepper, all are calming to the mind and shouldn't be forgotten. But before anything, I want people to be hydrating adequately, because when we are dehydrated, we can experience anxiety. So the liquids are about remembering the water and remembering that you can lean into these very calming teas that can help you. I love to make a little infusion of dried lavender and add fresh mint to a slice of lemon. It's just great for me, it's a very big pick-me-up, so I have coffee in the morning. But in the afternoon, I reach for something like that, which kind of sets me up for a little bit of energy, but also not a buzz that’s gonna get me anxious. It offers calming as well. The M is for more omega. Omega three fatty acids have a significant amount of evidence for anxiety disorders and they're worth adding in. Many people get their biggest omega-3 three fatty acids from fatty fish like salmon. But you can also get it from chia seeds, flax seeds, and walnuts, so plant-based sources as well. And then the S is for spices. So turmeric with the pinch of black pepper, oregano, and capsaicin, many of the spices have good properties and qualities that can help us and they're just worth adding. I want people to remember that there are different types of foods from different food groups, keep them at their fingertips, and try to eat them as much as possible. As you know, there are hundreds more foods in the book. But you also want to be able to go into the world with a few ideas that you can turn to all the time.
Elizabeth Stein 26:35
That’s a great tip and a good one to remember. As you think about it, I love that you have the 80-20 approach to your diet suggestions. That's 100% how I live as well, really having that balance. So as you work with clients who are coming to you with anxiety issues, and maybe they're coming to you and they're eating a lot of sugar and processed foods, how do you approach making the changes in their diet and lifestyle? It's certainly not easy going from eating 100% that way to being at 80-20 that way.
Dr. Uma Naidoo 27:12
That's such a great question. Because I think that part of my protocols evolved as I did more and more clinical work and research. I realized that giving people a list of things to do is very overwhelming. So to your point, Elizabeth, we want people to make slow and steady changes. And now I use the expression, it's a marathon and not a sprint. So let's start with the one thing that you have started to do that is we know it's not helping. And often I'll tell you, it's a great conversation starter for this type of work. Because someone will be worried about one food, it might even be a glass of wine that they began drinking during COVID. Or it might be the cookies that they stocked up on during COVID. It might be something that evolved during this phase of the pandemic. They often want to change it, but they're not quite sure how, and they know that they like it, and they look for it, and they crave it. So how do they work with it? So often, it's about first identifying it, and then what we can swap out, can we make a healthy version of that food, that beverage, that snack that they're looking for? And can they start to change that most nights of the week? If they can't give it up completely, can they start by doing this every other night? So swapping out that for a fruit with a piece of dark chocolate, one of my favorites is dark chocolate with a clementine. Can we do that instead of the bowl of ice cream? What I noticed is you take one habit like that that's top of mind for the person, and you can work with them to switch out just that habit. The moment that they start to feel better, that they start to notice they’re sleeping better, they feel calmer, something is changing, they want to do more. That's really when one can accelerate the plan to say, let's try these three things. So in addition to one habit, let's try two more things that you do. And you can slowly build it up from there. What has happened is the person now understands the link between changing how they eat and the impact and how they feel. And that's very powerful. Once we get there and that happens, if someone's following the plan, it happens for most people. And then we build up a nutritional psychiatry plate from there, using those guiding principles. Because if someone is only eating at a fast food restaurant every day, we can't just put this nutritional psychiatry plan in front of them and say, “Do this.” Because there's not going to be something they want to eat. They're going to have to build towards it. So, I find that that's a good way to work it out with someone.
Elizabeth Stein 29:52
That's a great tip and I think for anyone whether they're seeing a professional or not being able to self-identify and write down a list of all of those items that you're having issues giving up or swapping and start at the top of the biggest offenders and go one by one to give you that confidence. How long would you say you typically see with your patients that it takes for, maybe two questions, one to make that change, but then secondly, to really start to feel the effects of eating better, therefore helping to lower their anxiety?
Dr. Uma Naidoo 30:36
The effects can be as short as a few days to a week and as long as three weeks. Usually, by about two to three weeks, someone is noticing a change if they've been consistent, meaning that they made the effort. You can't do this once a week and then go, “Dr. Naidoo, why am I not feeling calmer?” You got to try it out once and do it today and do it next Monday and it's gonna work. It has to be consistent most days of the week. So there's a range of that and remembering that our gut microbiome is like a pumpkin. It's pretty individual response for each person. But in terms of how they implement this, they have to leave my evaluation, an action plan related to what it is we want to tackle first. So say I've started to eat a bowl of ice cream, this is a pretty common one. A bowl of ice cream, and different flavors every single night, we started this as a family tradition during the pandemic. I've heard this a lot. So what are we going to do now? Well, can we cut down on portion size? That's one thing. Can we have one scoop instead of three? And every other night, can we switch that out from a recipe that I wrote in This Is Your Brain on Food, my first book, and that's made from bananas? And you can even make it a chocolate flavor with extra dark, natural cacao. Again, all of these ingredients are helping your brain. Can we make a batch of that ice cream keep it in the fridge and switch it out? So every other night, can we have the fruit-based ice cream? Still, we want to control the portion, and we want to not be eating a massive bowl of it, and not adding tons of things to it. Can we enjoy that flavor? Can we save it? And can we switch it up? So that's just an example. Someone else may be turning to crunchy pretzels and a salty snack every single day. That's what they are looking for after dinner when they're watching television. Can we make a batch of spinach or kale chips in the oven, make them hot, take 20 minutes, sprinkle on your favorite spices, make it on sheet and the whole family has a crunchy snack made from a healthy whole food that they can eat? So what are the actionable ways? It's a recipe. It's an idea, it's a concept of changing it out, it's portion control. So they are living with a practical plan to make that work because eating this, not that mentality that we live in, in the United States is what helps people to fail. They can't sustain that habit. Unless there's a medical reason or there's a food allergy and intolerance. If they suddenly give up an entire food group, sometimes it's a healthy version of a food group, they tend to fail because they start to crave that food group and then they come back to it. So one has to be flexible, but also understand the motivations behind why they're doing it and help them stay on the plan as best they can.
Elizabeth Stein 33:46
As you think about advising patients, but they're eating it, certainly eating is a piece of it. But as we look at it holistically, many other pieces go into the factors of helping with anxiety. One close into what we're eating is how we're eating. So how do you advise, what tips can you share on how to be more mindful? Because I think so many of us, I can speak certainly to myself sitting, multitasking, eating at my desk, and doing work at this time. And then all of a sudden, I realize like, oh, I finished this lovely meal that I created for myself, and didn't even take a moment to enjoy it.
Dr. Uma Naidoo 34:30
It happens to all of us. In fact, as a resident in psychiatry, as a horrible leader, and as an intern, I would be eating while walking. I would be eating while standing. I would be eating something in the call room that wasn't healthy. We all learn from our different experiences. I think, first and foremost, we all live busy lives. Is there a way that we can take even 10 minutes at lunchtime? Maybe you combine your 10 minutes outside with eating whatever you have a lunch. And even if you haven't finished all of your lunch, because you're having a busy day, you eat some of it in that nice environment, and you eat the rest of it maybe at your desk. Sometimes it's hard for us to put aside more time. But I think when we start to do it for ourselves, we kind of put lunch into our schedule. I started doing that when I began writing my second book. I started to schedule lunch into my schedule because I found that between work phone calls meetings, and writing, if I didn't put it in, it was four o'clock, and I hadn't eaten. I think that becomes important. Scheduling it in, putting some time aside, changing sets. So going outdoors for 10 minutes, or sitting with your family for that 10 minutes, if they're available. I did the same for dinner. Putting in the time as much as possible. If you do have families, maybe you're on your own or you do Zoom with a friend, or you connect with someone so that you're sitting mindfully eating, you're enjoying it and saving it, you share the experience, maybe you cook the same dishes a friend is cooking. I often have my patients do that. Because not only does it encourage them along that healthy path, teaching their friend the recipe, they doing it together, it's kind of like pottering around those healthy habit changes. The thing is being in a mindful space, which is hard to do when you're in the middle of a busy day. I often have to change rooms, change my location, and put my laptop, and my phone aside for that period. Sometimes I'll speak to someone in our household, and I'll make sure that I'm not at my computer working when I'm eating, but I also find that when I do that, I'm enjoying my food. And I know it's affecting my digestion, I know, I'm chewing differently. I know I'm enjoying the flavors differently. And it's so worthwhile that I want to do it again. So that's when I started. It's not perfect, but most often at least, I look at my schedule, I know I've carved that timeout for a break. The other thing I like to do is build in stretch breaks and walking breaks and things that just help you pack up your day because, during the pandemic, it was just so hard. Many of us were at our desks and our computers for hours on end and had to walk ourselves back from the habits that came out of the pandemic too.

100%. I was looking at my schedule today. And it is every hour without a stop until seven o'clock. So I quickly get my food and then sit right back in front of the computer. Sometimes, it's unavoidable. But I do think being able to at least slow down and savor that meal certainly has to have, as you said, a better impact on our digestion and therefore our gut, and the anxieties that we might be feeling.
Dr. Uma Naidoo 38:26
Especially right now, I have days like that, and it's not perfect. I make many errors all the time. But I do find that if I close my computer and leave my phone in another room for 15 minutes, sit and eat in my kitchen or dining room, I might have to return immediately to my meetings and work. But even that little gap makes a difference to how I feel. Because you are taking care of yourself and you do that.
Elizabeth Stein 39:01
Absolutely. So I'd love to jump back a little bit more into the science and talk about metabolism. So you talked about the connection between the brain and the gut and anxiety. But as I said before, what was interesting to me was metabolism. And I'm sure this is one that you hear often or I feel like is more common where someone might say, “I'm having difficulty losing weight, and I don't know why and I'm anxious.” So those are all connected pieces. So if you could help uncover that for us, that'd be wonderful.
Dr. Uma Naidoo 39:40
Sure, it turns out that some of the research and the work I did on anxiety, some of the things that helped me understand my work more was understanding as well that metabolism and the parts of the brain that are dealing with metabolism, but also the same parts of the brain that are where anxiety is centered. The amygdala is a flashpoint for anxiety in the brain. The amygdala and hippocampus are involved with anxiety, but they're also actually involved with metabolism. One of the things I want people to understand is that when we make the connection between disorders like anxiety, and metabolism, there's science behind it. There's a way in which these are not just some things that we talk about. But they are connected. So if you are making an effort to eat healthier, move yourself away from those foods that are going to lead you towards metabolic disease and problems with type two diabetes, so you can have your diet, swapping out the foods that you weren't drawing for healthier versions. You are starting to not only help you improve your metabolism and your metabolic health, but you're also going to be impacting your anxiety. And I thought that was just super helpful for people to know because it's not a connection that we usually talk about.
Elizabeth Stein 41:11
One other connection is on the immune system. And if I'm more anxious, does that mean that I'm more prone to immune deficiency? Or how should we be thinking about that?
Dr. Uma Naidoo 41:28
So we talked about the gut and brain, we talked about inflammation. One of the things I should have said about the gut and brain as well is that 90% to 95% of the serotonin receptors are in the gut, and a large portion of serotonin is made there, a major neurotransmitter often called the happiness hormone. Well, another factor that we tend not to think about is that 70% of our immune system is actually in the gut. It's in the same area where food is being digested and our immune system is involved. Now the system is more complicated. So what I do in the book is break it down for people in terms of the different types of immune systems, different parts of the immune system, and the ways that it impacts us. But the bottom line about this is that the way that we eat impacts our immune system, impacts our anxiety. That's a very simple way of categorizing it. But I wanted them to understand that the immune system is involved in all of this, it's not separate from what we're doing if we're trying to work on anxiety.
Elizabeth Stein 42:43
So in this book, you've certainly uncovered so much research, over the last 20 years, as you were saying, like how much is involved in our understanding of the gut and the brain and how everything is connected. What's next in your research? Where do you think we're going in the next couple of years?
Dr. Uma Naidoo 43:02
What I'm most excited about is just the research around the gut microbiome, because we’re finding new solutions, especially some newer companies doing fantastic deep-level research. So beyond just the testing that we're doing in the gut microbiome, we are looking at the DNA and RNA of the microbe microbiome, and looking for patterns of how we can improve what your gut is giving us and the solutions that we can find through foods and supplementation, because we don't need perfect lives, and we don't eat perfectly even if we're healthy eaters. So, none of us is perfect. That's where supplements do fill in the gap, where we may just need a certain nutrient or a certain bit of help with a certain nutrient. That's where I'm excited because what I feel is that if we can get to the point of psycho-biotics, which is using food and other nutrients to work on mental health solutions, I think we'll be in a much better place. Research has shown that when we take the medication, not everyone receives permission or a full response. There are a good percentage of people who would prescribe medication, but just don't get better. And because we know that, we know that we need more solutions.
Elizabeth Stein 44:29
Your solutions of what we're putting at the end of our fork is just such an incredible point in our time to be able to make it more approachable. And as you said if you're not able to see somebody or get prescriptions or have insurance cover, what we're doing with our fork is of the utmost importance and impact that we can do every day. So thank you for all of your work and bringing your new book everyone must go read it. And we're gonna finish off with some rapid-fire Q&A.
Three things that you are currently loving. It could be a product, a TV show, a podcast, or anything.
Dr. Uma Naidoo 45:20
Alright, so I'll start with a really weird one. When my mom visited in July, she lives overseas, and she and I got into watching this really interesting BBC crime drama, called Midsomer Murders. And I like certain crime dramas, because they're clever, it's kind of like a fun thing to watch. I love that just because when my brain is stimulated, and I'm thinking, oh, well, who did it, that idea, I've enjoyed that. So we're way off from what I usually do. I love some of the ways that I've developed some recipes for lavender tea. I've been practicing them and trying them at home, and gotten into it and found it. Until I dug deeper into the work for this book and the research, I thought that there was often a stench of oil if I went from massage or spa treatment. But there are ways to make it into tea. That has been very exciting for me. I've enjoyed that. And the third thing I've been trying is to spend time growing a little garden. I don't have that much space, but I've been trying my hand at it since the summer. It's been fun. I am hoping I can keep up and tend to these little herbs because even if I have a little fresh batch every week, it uplifts my life, it uplifts my salad, it uplifts my food and it's just fun. It's a fun activity to garden a little bit and enjoy that.
Elizabeth Stein 47:06
Love that. What's your favorite medicinal herb that you're growing?
Dr. Uma Naidoo 47:10
I have to tell you, I love basil. I can't give it to one. I love cilantro, I love mint and I love basil. And relatively, I've had some luck with some of them. So if either one of them were in a spurt right now, I'd be happy always to integrate them into something.
Elizabeth Stein 47:32
Favorite words to live by.
Dr. Uma Naidoo 47:36
I would say, love, gratitude, and kindness.
Elizabeth Stein 47:43
Three foods that are always in your grocery shopping cart.
Dr. Uma Naidoo 47:49
Any type of leafy green. I'm a big leafy green person. So you'll find dandelion greens, romaine lettuce, and arugula. Cruciferous vegetables, you will always find me with either broccoli, cauliflower, or brussel sprouts. The third would be always refreshing my nuts, my seeds, and whether it's the flax seeds or needing more hemp seeds to make hemp milk. Those are usually things that I will need regularly because I go through them all the time.
Elizabeth Stein 48:27
A favorite book or podcast for growth.
Dr. Uma Naidoo 48:31
One of the books I've continued to rely on is Deepak Chopra’s The Seven Spiritual Laws of Success because I just find it has always granted me throughout my life since I was a teenager. I go back to it because I learn something new every time and it's not a huge long book. So, it's been a very meaningful part of, my journey.
Elizabeth Stein 48:57
And lastly, what are your top three anxiety-lowering techniques?
Dr. Uma Naidoo 49:03
I love breathwork. I encourage people to find a breathwork exercise that they can do and learn so that if they ever have a feeling of panic or anxiety that goes through their body they can turn to this breathwork exercise. So, that's a huge one.
Elizabeth Stein 49:27
What’s your favorite? Do you have a favorite breathwork technique?
Dr. Uma Naidoo 49:29
Yes, I like alternate nostril breathing, because I find it pretty easy to do. One can pretty much find a YouTube video on it to learn how to do it. So, I like that. Also, by the way, just the power of deep breaths. Just stopping taking that mindful moment in your day and taking a deep breath can just kind of help you reset as well. I like taking a walk, just being outdoors and I make every excuse to do that. And the other one is just having a mindfulness practice. It doesn't have to be a meditation. It can be words or thoughts or a peaceful scene that you close your eyes and meditate on, it doesn't have to be structured as what other people may be doing. But I've had different practices, and different types of meditation throughout my life.
Elizabeth Stein 50:28
