The One You Feed - Elissa Epel on Telomeres and How our Choices Affect Them and our Health

Episode Date: January 10, 2018

Dr. Elissa Epel knows a lot about the science of stress. As a health psychologist, she specializes in research surrounding the role Telomeres and their length play in our body's response to ...stress. In this episode, she explains how the choices we make emotionally, about our thought patterns, our lifestyle etc directly affects our biology in a very clear and measurable way. It turns out, our thoughts and our behavior have a measurable impact on our biology at a cellular level and there are things that we can do to make that impact a positive one. When it comes to telomeres, in most cases, the longer the better and you can do things to impact that variable of length starting today.

Starting point is 00:00:00 I really like to focus on what we can do now, today, and that's all we can control. Welcome to The One You Feed. Throughout time, great thinkers have recognized the importance of the thoughts we have. Quotes like, garbage in, garbage out, or you are what you think, ring true. And yet, for many of us, our thoughts don't strengthen or empower us. We tend toward negativity, self-pity, jealousy, or fear. We see what we don't have instead of what we do. We think things that hold us back and dampen our spirit.
Starting point is 00:00:41 But it's not just about thinking. Our actions matter. It takes conscious, consistent, and creative effort to make a life worth living. This podcast is about how other people keep themselves moving in the right direction, how they feed their good wolf. Thanks for joining us. Our guest on this episode is Dr. Alyssa Epple, a health psychologist focusing on stress pathways. For the past 15 years, she has studied stress in the lab and in the field using naturalistic stressors and associations with an early aging syndrome. Dr. Epple studied psychology and psychobiology at
Starting point is 00:01:31 Stanford University and clinical and health psychology at Yale University. She also completed an NIMH-funded postdoctoral fellowship at UCSF, where she has stayed on as faculty in the Department of Psychiatry. Her new book is The Telomere Effect, A Revolutionary Approach to Living Younger, Healthier, Longer. Our sponsor on this episode is Health IQ.

And here's the interview with Dr. Alyssa Epple.
Starting point is 00:02:10 Hi, Alyssa. Welcome to the show. Thank you so much, Eric. Your book is called The Telomere Effect, a revolutionary approach to living younger, healthier, and longer. And it's a fascinating book to me because really a lot of it talks about how the choices we make emotionally about our thought patterns and our lifestyle directly affects our biology in a very clear and measurable way. So we'll jump into that in just a moment, but let's start like we normally do with the parable. There's a grandmother who's talking with her granddaughter and she says, in life, there are two wolves inside of us that are always at battle. One is a good wolf, which represents things like kindness and bravery and love. And the other is a bad wolf, which represents things like greed and hatred and fear.
Starting point is 00:02:56 And the granddaughter stops, and she thinks about it for a second. And she looks up at her grandmother, and she says, well, grandmother, which one wins? And the grandmother says, the one you feed. So I'd like to start us off by asking you what that parable means to you in your life and in the work that you do. I think it's profound. I love it that your show is titled after it. It just reminds us of how much of our life experience is constructed by us, how much control we have over choosing what we experience. So, you know, whether it's internal things, negative or positive thoughts and feelings and experiences, or things that happen to us, we all have bad and good all the time. And this question of what are we going to choose to focus our attention
Starting point is 00:03:47 on is just so critical can't be understated because where we decide to put our attention is what we experience what determines how much we're going to remember positive or negative experiences, and of course, build on them and capitalize on them. So it just says so much about really our psychological power to choose our story in a way. Yep. And your book is really fascinating because it talks about the implications of choosing that story and what that looks like. There's a great quote that you say early in the book from a researcher by the name of George Bray. And this really gets to kind of what you said in the intro about things aren't
Starting point is 00:04:35 necessarily fixed. We have a tendency to think of genetic traits as being like, well, I have this genetic trait. And his phrase was genes load the gun, and environment pulls the trigger. And that environment is not just our physical environment, but but our mental environment as well. Absolutely, exactly. It's just so easy for us to feel that our health is determined for us, you know, by our family history, and by our genes. And what we know is that at least 50% of the variance in whether we die early, whether we get sick early from this or that is our behavior. And of course, what shapes our behavior? Much of that is our psychological experience, our volition, and taking a step back from that, it's our social environment, our neighborhoods, our
Starting point is 00:05:28 relationships. So there's all these factors that we can try to shape to be a better life for us and for those around us that we have control over. So we control our aging much more than we ever thought we could. We control our aging much more than we ever thought we could. We can see how people's different experiences on a daily basis are associated with some of the biological aging that they undergo. Well, let's jump into the book in a little bit more detail. What is a telomere?
Starting point is 00:05:58 So people like to think of telomeres as the tips at the ends of their shoelaces. So if you think of those plastic aglets at the ends of shoelaces and you think of telomeres as the tips at the ends of their shoelaces. So if you think of those plastic aglets at the ends of shoelaces, and you think of your shoelaces as the genes, the DNA that makes us who we are. And then at the very tips are these protective caps, still made of DNA, but not genes. And it's very, these caps are very important to protect our genetic code from any damage from fusions. And as our cells divide, these protective caps get shorter and shorter. So there's something that happens to all of us with age, which is telomere shortening. And when they get to a critical shortness, the cells become old and they cannot divide
Starting point is 00:06:41 any longer. And they tend to become pro-inflammatory. So they not only can't do whatever job they were supposed to do, like fighting infections, if we're talking about immune cells, but then they start wreaking havoc on our health by secreting inflammation into our blood. So we really want to keep telomeres long and sturdy and stable throughout our lifespan. And the good news is that while the genetics determine some of how long our telomeres long and sturdy and stable throughout our lifespan. And the good news is that while that genetics determines some of how long our telomeres are, it looks like our lifestyle and social factors and nutrition, all of these factors are also shaping our telomere length.
Starting point is 00:07:20 Telomere is the correct pronunciation. Is that it? Yes. So it sounds like a longer telomere is a better one for us and that there's lots of studies from reading the book about different things that cause us to have a longer or shorter telomere. And we can talk through what some of those are, but one of the things I thought was really interesting in the book was it says that it's been suggested that telomere length may be the holy grail for cumulative welfare. Can you talk a little bit about that? Yes.
Starting point is 00:07:51 That was an animal researcher, Dr. Bateson, titled that as part of his paper. And it was just such a provocative thought. And then it turns out there's some data to support that. So what telomeres are associated with so many different factors in human lives, all the exposures that we're exposed to from our environment, from chemicals, our social environment, our psychological state, our health behaviors, and they all kind of add up to shape the rate of how quickly our telomeres shorten. And when we think about, can we take a person or an animal and measure their telomeres? And what does that tell us about their life history?
Starting point is 00:08:37 It's hard because telomeres are affected by so many things, including genetics. We can't make really accurate direct predictions, but in general, we can look at the telomere length of a person and find that it's associated with their history, their kind of cumulative history of adversity, all of the really difficult things that happen to them. And, you know, there's a few studies on this now. Even a stronger effect is what happens to us in childhood turns out to be really important in shaping our telomere length as adults. So, you know, it's a critical period of growth and vulnerability. So we really want to protect children from toxic stressors like poverty and violence and neglect, because those are the factors that really imprint on telomeres. Now,
Starting point is 00:09:22 Dr. Bateson was asking about animals and animal welfare and suggesting, why don't we apply this to animals and really look at the quality of their life, especially those who are, we control their environments that they grow up in, and they could be in factory farms, they could be in more humane conditions, and their telomeres might tell us a clue of their welfare. So this is not science that's kind of out on the edge. This is pretty well-known, robust science. You wrote the book with Elizabeth Blackburn, who is a Nobel laureate. So this idea of telomeres and their length and how that affects our overall health and the things that can improve those, this is pretty robust science,
Starting point is 00:10:03 right? It is robust. I can tell you where there's questions and controversy too. What's robust is that there are so many studies showing that the length is predicted, the length matters. So in midlife, for example, shorter telomeres statistically predict getting diseases of aging kind of across the diseases earlier. Cancer is an exception. So it turns out for some cancers, longer telomeres put us at more risk of these cancers. There is a question of, well, is this just kind of a factor that, you know, changes with age, like so many things in our body, or is it causing aging? Is it really a mechanism? And so that's been a question for a long time. And now we know
Starting point is 00:10:45 that it is definitely at least a small causal part of our aging. And we know that from these genetic studies, we call them Mendelian randomization studies. So people who have the genes for longer telomeres are less likely to get early heart disease or Alzheimer's dementia. get early heart disease or Alzheimer's dementia. Got it. I'm stepping way out of my knowledge zone here. But do telomeres have anything to do with whether or not genetic mutation occurs? So it's a good question. And most of us have common genes for telomeres. They might be, you know, code for short or long telomeres, but they don't make a big difference. And then there are some people who have these rare genetic mutations that cause them to have very short telomeres. So, you know, maybe half the amount of telomerase, the enzyme that protects telomeres as normal people. And so we have learned from those very sad genetic conditions that people do tend to develop some, you know, pretty severe
Starting point is 00:11:47 health problems like bone marrow failure, and they tend to die much earlier in life. And they tend to transmit very short telomeres to their offspring. And one thing that's so interesting is that while they might transmit the genes, the mutated genes to some offspring, other children don't get the mutation, but they still inherit the short telomeres. And what that means is that we don't have just genetic transmission, which always occurs, but we have an epigenetic or direct transmission of telomere length. If mom and dad have very short telomeres, it appears that's passed on through the sperm and egg to what the child ends up with. I'm Jason Alexander.

And here's the rest of the interview with Alyssa Apple. Let's talk briefly, you mentioned it earlier, talk about the role of inflammation, both in our overall health and then how that ties to telomeres. So inflammation is really important. We think that it's one of the major kind of highways of aging, of how our bodies age.
Starting point is 00:15:21 So when we're cut, we want to have a big inflammatory response to help us heal. But what we don't want is a slow drip of inflammation in our blood as we age. And we call that inflammatory aging. And that's what happens when our tissues get old and we call them senescent. They start secreting these inflammatory factors and that builds up. It comes from fat and from immune cells, from bone. There are many tissues and cells that start secreting pro-inflammatory cytokines. So when this builds up, it's feeding all of our body and organs and tissues and it's creating a fertile ground for diseases such as cancer. So we want to be doing things to reduce inflammation, like
Starting point is 00:16:06 having an anti-inflammatory diet. Now that sounds fancy. And if you look at what's anti-inflammatory, it's simply this, it's a whole food high fiber diet. It's like the Mediterranean diet versus eating a lot of things like red meat, processed meat, soda, a lot of refined carbs. Those are going to be promoting inflammation in our body. It's always interesting to me, there's so much noise about diet and so many different approaches and all that. But it seems like there are a couple key principles that everyone agrees on, like eat less processed foods and eat foods that are closer to being whole foods. Then there's some variations beyond that, but at least that seems to be consistent. I could not agree more. I think that everyone is confused and, you know, we've got some
Starting point is 00:16:55 real issues in nutrition research and one is conflicts of interest. If you look at the different sides battling, you often have food industry funding the side that says sugar doesn't cause disease, etc. Yeah, I agree. It is confusing. I always like when I can find a point of common ground among a bunch of different positions because then I can go, okay, well, that I can at least probably count on to some degree. And I think, you know, these nutritional basics that you just summarized so well, they add up across whatever we're looking at. We know it's this, you know, it's this high antioxidant, high inflammatory diet, let's say Mediterranean diet that causes less of a glucose and insulin spike. So when it's less processed, we have a better,
Starting point is 00:17:44 more stable metabolic response. This is the response that's better for the heart. It's better for the brain and it's better for the telomeres. So it lines up very nicely to be a strong, consistent story about biomarkers in early aging, as well as diseases of aging. These are all fed by the high glycemic, high carb, high meat diet, and the opposite can help prevent them. So it is not new people want the new exciting trend, but really, you know, eating well means going to the store, buying the fresh produce and trying to have less of the tempting, you know, what we call comfort food, not abstinence, but just less of it. You know, we do these studies trying to help people with our, you know, very understandable food drives,
Starting point is 00:18:32 right? We get hooked on the highly palatable food. And so we use mindfulness skills and we try to help people deal with those cravings so that they can make the choices they want to be making. Excellent. Let's talk about depression. Depression comes up in several places in the book, and you sort of summarize it up by saying the arrow likely points in both directions with depression. Short telomeres may precede depression, and depression may speed up telomere shortening. So what do we know about depression and telomeres? Yes, this is a great question. And it just shows the complexity of the mind-body connection, how factors move together. So what we know is that when people have longer depression and untreated depression without
Starting point is 00:19:20 antidepressants or therapy, their telomeres tend to be shorter in a dose response fashion. So it looks like depression is causing faster wear and tear on our cell aging. But then we also know that there are several studies that show that people at risk of depression before they're ever depressed tend to have shorter telomeres. So a colleague, Ian Gottlieb, showed this with young girls. They were at risk of depression. Their mothers were depressed. They'd never been depressed. And when he looked at their stress response, they had exaggerated emotional and cortisol responses to stress, and they had shorter telomeres already, no depression. And the
Starting point is 00:20:01 bigger their cortisol response, the shorter their telomeres. So we know that stress can kind of promote shorter telomeres as well as vulnerability to depression. So it may be that the telomeres came before the depression. It may be that the animal studies suggest that shorter telomeres in the brain and the hippocampus put the rats at risk of depression. And when they can boost up the hippocampus with telomerase, they're more resistant to depression. So there's all sorts of bidirectional pathways. And just to add an even another wild card, in one recent study, when researchers compared people with depression to people without depression, so cases and controls, they found that the people with depression were more likely to have this gene that causes short telomeres. So all of a sudden, now we're looking at, you know, possible genetic predisposition to have short telomeres and to have
Starting point is 00:20:57 depression. It's a complicated web. And I think, you know, these are hard to parse out in humans, we need to study people, you know, in a sense, kind of across the lifespan and the next generation, look at the genetics at the same time as we look at their actual telomeres. people can do that can help increase telomere length. And interestingly, they're the very same things that people would do to deal with depression, to deal with anxiety. So it may be a little chicken and egg, but the good news is we don't have to have the answer in order to do the things that are beneficial. And so the thing that I think is so fascinating about this, a lot of the concepts that we're going to talk about in a minute here are going to be things that we cover on the show fairly regularly. And reminders are always great for these things. What I loved about your book, though, and I think this one line really sums it up.
Starting point is 00:21:56 It says, we can change the way that we age at the most elemental cellular level. elemental cellular level. So everything that we're about to talk about are really good strategies that we've also seen in studies that are truly working at a cellular level. And I think that's such an interesting thing to take these ideas that we think, well, that works, makes my mind better, makes my mood a little bit better, and recognize that we're really able to measure these things, the effect of them at a true biological level. So let's start with something called the challenge response. Can you tell me a little bit about what the challenge response is and how that helps? Sure. So one of the areas of research that we've been doing that looks at the acute stress response is trying to look at how people approach a stressful situation in different ways. And a natural evolutionary-based way is when we feel our survival is threatened, physical survival is threatened, or our social survival,
Starting point is 00:23:03 if our ego is threatened and we feel like we're going to be embarrassed, humiliated or fail, this triggers a threat response in the body characterized by high cortisol and kind of the autonomic nervous system vasoconstricts. Those patterns of reactivity, if we have them over and over, over time, they are causing more wear and tear on our body. They're making us more vulnerable to stress-induced diseases of aging. So what the kind of antidote to that is, of course, we're all going to experience stressful events, little ones and big ones. And what we can do is try to respond with a good, strong stress response and recover quickly. And that profile is going to be
Starting point is 00:23:47 related to slower aging. Now, how do we cause our stress response to recover quickly? Well, think about, you know, number one, when you approach a stressful event, you want to remind yourself that the stress response is your friend, it helps you cope, and it energizes you. And it, you know, helps you problem solve better. So just those thoughts of rethinking the stress response in a positive way can help our body have a more helpful stress response. We call it the challenge response, stronger cardiac output and more adrenaline than cortisol. So we want to have a positive challenge response. And then once the stressor is over, it's very easy to
Starting point is 00:24:27 ruminate about it. We call this perseverative thinking. We continue to think about it long after it's passed. That keeps up the stress response, but we can actually try to notice that we're ruminating and let the situation go and have a quicker psychological recovery, which leads to a quicker physiological recovery. So just, you know, close up, looking at your stress response, you know, how are you feeling? You can cope with the situation. And once it's over, can you help it end with a crisp ending, you know, take a walk, get social support, do something to cut down on rumination. Now there's other things we can do
Starting point is 00:25:05 to boost our stress resilience, like exercise, like getting enough sleep. These things are actually related to less rumination. So ruminative thinking is a natural habit that many of us have that we can kind of notice and try to nip in the bud more than we do. Rumination is an old friend around these parts. I'm Jason Alexander. And I'm Peter Tilden.

And you can find it on the I heart radio app on Apple podcasts or wherever you get your podcasts. There are a couple of these that fall under the category in my mind of perspective of getting a different perspective on things, which I always think is so helpful. And one of them is called linguistic self-distancing. Can we talk about that? Yeah, that's research by colleagues of mine, Oz Adek and Ethan Cross. And so what they've shown is that when they bring people into the lab to kind of rel in a third person, a very analytical way that actually reduces their emotional response, gives them perspective. They can do time distancing and they can ask themselves,
Starting point is 00:27:56 is this situation really going to affect me in five years? Usually the answer is no. So while it seems like a crisis at the moment and our body's responding as if our survival depends on it, when we remind ourselves that we are, this really in the big picture doesn't make a difference, right? And we shouldn't sweat the small things. This helps people rapidly recover from the stressful situation. So it's helpful just to kind of take a step back and, you know, realize it's not about avoiding stress. Stress is inevitable. We all are going to face challenges that are unpredictable, that come up at different times in life. And it's really about coping with
Starting point is 00:28:38 it in a way that doesn't amplify the stress in our mind and continue it the whole day. Even while we're, you know, sleeping, we can be more kind of vigilant and aroused. And really, there's always the next moment when we're not coping when when an immediate crisis is over, when we can find peace in that moment. And we can be finding, you know, joy, even though we might be dealing with a terrible chronic situation. So there's always momentary relief and momentary absorption into the moment that is so important for our bodies and respite from chronic stress. Yeah, I love the time distancing. You don't even have to go out to five years. I think a lot of times I'm like, well, this matter in five hours, five days, five weeks. And in a lot of cases, I like, well, this matter in five hours, five days, five weeks. And in a lot of cases, I'm getting upset about something that in five hours, I probably won't
Starting point is 00:29:29 remember, like being stuck in traffic or other things. So time distancing is a great one. And what you were saying there about the stress response reminds me of some studies I read, where it's not so much the stress, that's the problem, but what we think the stress is going to do to us also. So our belief in what stress does has some of that. And that gets to the challenge response. Instead of thinking this is awful, I'm stressed. And boy, it's going to have so many bad effects on me to look at it as, okay, this is, as you mentioned, priming my body or getting me focused. And even that thinking of it it differently, just lessens the impact that it has. Yeah, exactly. It's beautiful. Is there anything that you think we should talk about
Starting point is 00:30:14 before we wrap up? We've got just a few minutes left, and I want to make sure if there's anything that you want to cover that I get that in there. Eric, I would love to hear from you any reflections on the parable and what that's like to hear different interpretations and soundbites of it every day over time and how you think it relates to this book. Boy, you're turning the tables on me here. Good at that. You're not supposed to answer a question with a question, I think, is the phrase. It's interesting.
Starting point is 00:30:46 The way I think it relates to the book is kind of, as I mentioned a little bit earlier, that, you know, the parable is about making choices. To me, it's hard. And I think the reason it's a parable is because you hear it and you almost immediately understand it on one level what it means. You're like, oh, it means that I have to make choices and decisions what I do with my, you know, my thoughts, my behavior and my emotions to the extent that I can work with those things I should. And I think that the part of the book that I loved was that you're covering a lot of the same ground as far as the things that you do to work with your thoughts, your stress, your emotions. But I really love when it's that concrete ties it back to biology. And I also love that a lot of what you're showing is that these telomere lengths can be modified. So we're not just, if I have shorter telomeres,
Starting point is 00:31:40 doesn't mean that I'm doomed. Right. I'm not doomed. I can actually do things in my day to day life. I can, I can choose to feed the, the good wolf and that will improve those telomere lengths. And so that we have a choice in what we do. And not only do we have a choice, that choice actually makes a difference. Beautiful. You said it so well. That is a huge theme of the telomere story and how our aging is so malleable. Lots of people like to know what their telomere length is and there's nothing wrong with that. I don't know how the tests aren't necessarily that accurate yet. And I'm the type of person who I don't really want to know mine because I know where I've been and they're probably short. And I really like to focus on what we can do now today. And that's all
Starting point is 00:32:35 we can control. And so really, even if someone has very short telomeres because they've had a lot of childhood hardship, that's not worth measuring them to see that because what matters is that what they do today can be changing up that system, can be increasing the telomerase, can be reducing the oxidative stress and the inflammation. These are things we can control. Yeah, that's a great point I was gonna ask.
Starting point is 00:32:58 Can people measure their own? But I agree with you in general. I don't think that's a particularly useful approach. It's much more about what can I do now to improve that situation? Although it would be great to see a lengthening over time so that you knew that what you were doing was having an impact. Right, right. And I think eventually we might get there with more, you know, accurate and frequent
Starting point is 00:33:21 measurements. And that would be, you know, if someone is starting a, you know, a pretty intensive program for health improvement in some way, it would be an interesting experiment to look at pre-post. Yep. Yep. Exactly. So one final question, you've talked about telomerase. Did I say that one right? Close. Telomerase. Telomerase. All right. As a chemical that helps. And is there treatments that we think are forthcoming?
Starting point is 00:33:49 It's a good question. I don't have a good answer. We just don't know enough yet. We do know that at least from observational studies, we know that telomerase tends to be higher. Well, for example, smoking decreases it and being physically active increases it. And we know from a few intervention studies that it looks like we can boost the telomerase with mind-body activities like meditation and Qigong. And so that's super

So just a little bit of a question mark about what the risk benefit ratio is of those kind of over-the-counter products to increase telomerase. And the risk is nothing to take lightly because if you have too much telomerase, if you're prone to cancer, and if a telomerase supplement could kind of push you over that threshold, then you are more at risk of cancer. So it's a possibility is all I'm saying. Yeah. Well, thank you, Alyssa, so much for taking the time to come on. I've, I loved the book and I'm glad we got a chance to sit down and talk about it. Thank you so much, Eric. Wonderful questions. And hopefully something I've said is
