Neal Barnard: Oh, that’s lovely. Thank you.
Neal shares his pathway and what influenced him as a physician and being plant-based
Kimberly Snyder: One of the things that struck me first about, when I’m reading through your body of work and your bio, is the fact that you’ve authored more than 70 scientific publications. And your overall approach to diet includes being plant-based, as I am. I’ve been plant-based now for over 12 years. So one of the things that I hear about from readers and listeners in our community is objections from their standard doctor when they decide to go plant-based. Concerns about protein and things that have been so widely disproven as not really legitimate concerns. But I’m just curious, Dr. Barnard, when you started out as a physician, were you plant-based, or was that influenced by what you uncovered in your research? Can you tell us a little bit about your pathway?
Neal Barnard: Sure. Well, first of all, I grew up in North Dakota, and I have to tell you, I never met a vegetarian or vegan or anything. I had never even heard about it when I was a kid growing up. However, what actually happened to me, the year before I went to medical school, I had a job in a hospital in Minneapolis, and my job was in the basement of the hospital in a part of the hospital that nobody would ever go to. It was the hospital morgue. And whenever anybody died in the hospital, they would bring the body there, and the pathologist would do an autopsy to determine the cause of death, and my job was to assist at the autopsy.
Neal Barnard: And one day, there was a man who died in the hospital of a massive heart attack, probably from eating hospital food, but that’s another story. Anyhow, so the pathologist cut a big chunk of ribs off the front of the chest so that he could expose the heart, and he set the ribs on the table, and the heart was filled with atherosclerotic plaque. In other words, he would open up an artery, and instead of being wide open, it was all… It was almost like a rusty pipe inside. And he said, “Look, this is atherosclerosis. This is what comes from eating bacon and eggs and whatnot.”
Neal Barnard: And then we looked at the arteries going up to the brain, and it was the same process. So the pathologist wrote down all his findings, and he left the room, and I had to clean everything up. So I put the ribs back into the chest and made them fit with the other ribs, and I sewed up the skin and cleaned everything. And then I went up to the cafeteria when I was done, and they were serving ribs for lunch.
Kimberly Snyder: Oh!
Neal Barnard: And I want to tell you, I thought, “That looks just like a dead body.” And I said… You know, it smelled like a body.
Kimberly Snyder: Ugh!
Neal Barnard: So I realized it is a dead body. It’s just not a human body. And I didn’t become a vegetarian on the spot, but I could not eat that, and it started to play in my mind, kind of the links between what we put in our mouths and what kills us. And as time went on, I learned more about the role of nutrition. I started medical school. I started learning more, and I also started to connect the big picture, because the environmental movement was maturing at that time, and also the idea about how animals are mistreated started coming into my consciousness, which was a 180 degree turn from how I grew up. I realized there’s-
Kimberly Snyder: Did you grow up eating a lot of dairy and meat, I imagine, being from the Midwest?
Neal Barnard: Well, not only that, I hunted. I mean, I hate to tell you this, but it’s true. I grew up in North Dakota, so I hunted. And my extended family raised cattle, and I personally drove cattle to slaughter at the slaughterhouse. And we didn’t… Well, I mean, you could tell that it was kind of a creepy thing to do, but we would just figure this is business.
Neal Barnard: Anyway, I started to rethink all of this, and once I finished my residency training, I thought, “Okay, enough is enough.” And I started a vegan diet at that point. I want to tell you, it was easy and a great decision, and it just makes you start thinking about the world in a really different place. Then, of course, as time went on, then we started to learn that a plant-based diet can reverse heart disease and help people lose weight really, really easily, and it tackles diabetes and things. But then we also started getting involved in doing the research itself to prove these benefits.
What Neal’s family’s reaction was when he chose not to eat any animal products and if there was resistance or curiosity
Kimberly Snyder: Mm-hmm (affirmative), mm-hmm (affirmative). What was your family’s reaction when you said, “Hey, this is so different than how I grew up, but guess what? I’m not going to eat any animal products anymore”? Was there natural resistance? Were they curious? Did they come on board? Maybe not at first.
Neal Barnard: Very, very slowly. I really pushed my mother to follow suit because she had high cholesterol, and she didn’t want to change. And you know what? People don’t take advice from their third-born child, you know?
Kimberly Snyder: Mm-hmm (affirmative).
Neal Barnard: I would give my mother all kinds of advice. I would leave books for her. And you know how you can tell when a book hasn’t been opened?
Kimberly Snyder: Sure.
Neal Barnard: I would go back and visit her six months later, and the book’s in the same spot. And I realized parents just don’t take advice from their kids, especially not those who are in the middle of the pack, like me. Eventually, though, my mother’s personal physician basically threatened her with a statin. He said, “You’re going to have to take cholesterol-lowering drugs because your cholesterol is dangerously high.” So without telling me, my mother started a vegan diet. She went back to her doctor about seven weeks later, and the doctor took her cholesterol again, and it had dropped so much that the doctor was convinced that the lab equipment must have been broken.
Kimberly Snyder: Wow!
Neal Barnard: So he told her she had to come back and check it again because there was some physical problem with the machinery, and she just started laughing about this. Then she… Because she was the cook for my dad, he became vegan by default, and they continued that way for many years.
If there are any changes with how physicians view a plant-based lifestyle and if there is still some resistance
Kimberly Snyder: Wow! It’s powerful. It took my dad about five years to come from a very, very meat-heavy diet, burgers, very traditional, to now I would say he’s about 98% vegan. So to your point, sometimes it takes some time with parents, but I think that you plant little seeds of information from me, and then when they start trying it and they start feeling better is that is… The proof is in the pudding. But, Dr. Barnard, as a doctor, I love your approach, where, again, you’re going to the science of it. And again, to what I was saying earlier, there’s so many physicians that are also MDs and seem to be either, to speak bluntly, clueless about the benefits of a plant-based diet or even resistant because that’s not what they know. It’s not what they’ve studied in school. Do you see it changing with all the research coming out slowly but surely? Do you have hope that other physicians will wake up to this, or do you think the resistance is still very much there?
Neal Barnard: Yeah, it’s interesting. I have to say, I think you’re putting your finger on something really important, that on the good side, there are more doctors and healthcare providers, in general… I’m talking about nurses and dieticians and others. There are more and more of them who really are taking a huge interest in plant-based diets. And the reason I say that is every year we have a conference here in Washington. We just had it in July, and it’s called the International Conference on Nutrition in Medicine. And you look out over the room, and there are a thousand-plus physicians in the seats really, really excited about what nutrition can do. Top researchers come, and they’re comparing notes not just about heart disease or weight loss, but about every kind of condition, from diabetes to rheumatoid arthritis to just better mental health and so forth.
Neal Barnard: So yes, there is more excitement than ever, and I don’t need to tell you that the marketplace is responding with vegan products and vegan restaurants and one vegan film after another. But the other piece of this, Kimberly, that you were, I think, really touching on in an important way, is that there still are people who, to use your word, are clueless, who… I think they would not necessarily have been blamed 40 years ago, because the role of nutrition was not all that clear, but now it is clear. So when a patient comes in and sees some of these doctors and they’ve got a high cholesterol, what does the doctor do? They write… The doctor doesn’t say, “Well, the reason you have a high cholesterol level is because you’re eating saturated fat from animal products. You’re eating cholesterol, which is in animal products. And if you stopped eating those things, your cholesterol would very likely come back to normal.”
Neal Barnard: No, they don’t say that. They say, “Here. Is there a pharmacy near you? Here’s a slip, and you go fill it.” And once in a while, doctors will say, “Well, patients won’t change their diet. They’re resistant. They’re not compliant.” But you know what? Studies have looked at what happens when you give them a prescription for a drug. In maybe 30, 40% of the cases, the patients throw that away. They don’t want to take pills.
Kimberly Snyder: What?
Neal Barnard: Yes.
Kimberly Snyder: 40% of cases, people throw away the prescript sheets?
Neal Barnard: Specifically for statins, when doctors prescribe these cholesterol-lowering medications, in a great many cases, the patients do not want to take them, or they start and then they stop. They think, “Why am I taking this darned drug?” Now, part of it is that these drugs have side effects. Statins… You know what I’m talking about.
Kimberly Snyder: Yes.
Neal Barnard: The typical cholesterol-lowering drug, like Lipitor, they’re a hugely popular drug making lots and lots of money for the pharmaceutical manufacturers. It looked pretty innocuous except that it started causing muscle pains and liver toxicity. Not a lot. You can stop it if those things happen. But then we started to discover that it causes a little bit of weight gain, and it increases the risk of diabetes, not a lot, but a little bit. Then we started to see unusual cases of dramatic memory loss in people taking Lipitor and other cholesterol-lowering drugs. Again, these side effects aren’t in everybody, but they are in enough that you think, “Wait a minute. You don’t have a Lipitor deficiency anyway. What you’ve got is cheese and Spam and pork chops and… “
Kimberly Snyder: Spam.
Neal Barnard: “… these things in your diet. If you take them out, you’ll be better.” You know what I’m talking about.
We discuss high-fat diets and what they do to your body
Kimberly Snyder: Oh, yes, yes. Now, what do you think, Dr. Barnard, about some of these really high-fat diets? For instance, keto is very popular right now. What would you say to someone that’s like, “Oh, well, look at the research about people losing weight on these really high-fat diets,” which there’s plant-based keto, but then there’s a lot of people on animal-based keto as well?
Neal Barnard: Well, I wouldn’t do either one. The diet that we would recommend, that we have shown, and that if you do head-to-head studies of a healthy plant-based diet versus one of these so-called ketogenic diets, the weight loss on the plant-based diet is as good or better over the long run, and it’s much, much… It’s dramatically healthier for you. It started out as Atkins, the Atkins diet. And then it kind of disappeared for a while, and then it came back as South Beach. And now it’s come back as keto, and anything that has four letters becomes very popular instantly. So if people are thinking about a ketogenic diet… And what they mean really is that if you take out carbohydrate, which means fruit, beans, grain products, like bread and pasta, root vegetables, like sweet potatoes and potatoes, if you don’t eat any of that, given that that’s about 50 or 60% of what you would normally eat, you’ll lose weight, because you’re leaving out foods. There’s nothing magical about it.
Neal Barnard: So your body is starving for the carbohydrate it needs. Your body needs carbohydrate to produce glucose to run your brain. So now you’re starving for it, so your body instead is desperate. It makes these ketone bodies, which will power your brain, and you’ll go for a while, and people can eat that. And the only reason they’re losing weight is because they’re not eating the normal amount of food. But there are several things wrong with that, and the reason I would not go that way. The alternative way to lose weight, the better way to lose weight is a completely plant-based diet where you’re eating all the fruit you want.
Kimberly Snyder: All the fiber.
Neal Barnard: All the vegetables you want, because you’re getting fiber now, which gives you a healthy digestive tract and a healthy microbiome, which you need for a healthy brain. In fact, when you look… Speaking specifically for brain function, when you look at people who follow the ketogenic diet, their moods often descend and you… Well, anyway, you’ll see. I mean, when you meet these people, you know.
Neal Barnard: The other thing, though, is that when you look at people who follow plant-based diets, their moods very often improve. We happened to notice this with a study we did at GEICO, the car insurance company, where we weren’t doing the study for that reason. We were doing it for people with weight problems and diabetes. But along the way, we measured their moods, and their moods very often improved. That’s partly because they’re healthier, but partly their gut microbiome is healthier. But it’s more than that.
Neal Barnard: On a plant-based diet, because you’re saying yes to fruits and yes to healthy vegetables, you’re getting vitamins and antioxidants that your body needs for health. When people follow ketogenic diets, they’re afraid to even eat an apple.
Kimberly Snyder: Oh, my God. Don’t even get me started, Dr. Barnard. We have
Neal Barnard: They won’t eat a mango. They’re-
Kimberly Snyder: Oh, no bananas.
Neal Barnard: So what they’re saying no to is not just healthy fruits, but what they’re saying no to is all the antioxidants and natural chemical protectors that our species and even beyond our species, all great apes, have evolved with over the millennia, and you’re saying no to them. So what we presume, but luckily people don’t stick with the diet long enough to really know, but over the long run, you’re going to be at higher risk particularly for certain kinds of cancer. But what happens even over the short run is that, on average, cholesterol levels worsen. Now, not everybody. It’s quite variable. But usually when people lose weight by any means, if you go on just a starvation diet, if you go on a keto diet, even on a vegan diet, any kind of diet, cholesterol levels normally fall when your body gets smaller. For every pound you lose, your total cholesterol drops about a point.
Neal Barnard: But the exception to that is ketogenic diets. On average, cholesterol levels worsen. And about maybe one in three, one in four, maybe… I’m sorry, one in three, maybe even one in two ketogenic diets, their cholesterol levels go up. Especially their bad cholesterol usually rises about 10%, on average, and that means you’re at cardiovascular risk, specifically heart disease and stroke. And then over the longer run, if you follow these people over the long run, people who follow low carbohydrate diets have a much higher mortality over time.
Neal Barnard: So my thought is why do that? Whether you like it or not, you’re a great ape. You’re
