Welcome back everyone, I’m Brian Sanders and I quit my job and have dedicated my life to the investigation of nutrition and lifelong health. I’m creating the feature length documentary Food Lies, this podcast, and a health technology company here in Los Angeles with a doctor and 2 other partners. Today my guest is Dr. David Klurfeld, which is a quite a treat. This is his first podcast appearance and had to get special clearance to be able to participate. He couldn’t talk about certain things because he’s the National Program Leader for Human Nutrition in the Agricultural Research Service of the USDA since 2004. He was also on the working group of the World Health Organization that decided meat causes cancer in 2015. I won’t leave you guessing - he was very opposed to it and called it “the most frustrating professional experience of his life.” He’s accumulated a vast amount of knowledge over his 40 years researching nutrition and dietary factors in cardiovascular diseases and cancer. He wrote an amazing peer-reviewed article defending meat titled “what is the role of meat in a healthy diet” which I linked to in the show notes. https://academic.oup.com/af/article/8/3/5/5048762 He’s not going to support a fully carnivorous diet, but certainly sees past the bogus vegan propaganda Speaking of support - PLEASE support Food Lies on Indiegogo. Thanks for everything so far. The campaign just ended but Indiegogo allows us to keep funding because we hit our baseline goal. We need a bit more help to hit the real goal, however. Pre-order a copy of the film or check out some of the other perks. Also, this podcast has a website that I have barely even mentioned. Check out peak-human.com for all episodes and detailed show notes. A little more about Dr. Klurfeld before we start: He is responsible for the scientific direction of the intramural human nutrition research conducted by USDA laboratories. He has published more than 200 peer-reviewed articles and book chapters. He was Editor-in-Chief of the Journal of the American College of Nutrition for 6 years and is currently Associate Editor of the American Journal for Clinical Nutrition. He is also a member of National Institute for Diabetes, Digestive and Kidney Diseases Advisory Council. Let’s just say he’s done his homework… and still enjoys a good steak… here he is!   Show Notes Dr. David Klurfeld focuses his research on the 3 macronutrients and their effect on health on chronic disease - specifically breast and colon cancer People debate on how much what we eat affects diet and disease A paper published tries to stick all of cardiovascular disease precisely on 10 factors https://jamanetwork.com/data/Journals/JAMA/936095/joi170008f1.png Full article: https://jamanetwork.com/journals/jama/fullarticle/2608221 David and I spoke earlier and are on the same page - there’s no one-size-fits-all solution for how to eat, and nobody should pretend they have all the answers. There’s a framework and some general guidelines, however, that people should be aware of (if this isn’t already abundantly clear, this is the goal of the Food Lies film They have high salt as #1 factor of “cardiometabolic mortality attributable to dietary habits” and #2 being “low intake of nuts and seeds” There’s no evidence to support these specific quantities like amount of PUFAs Residual confounding is a big problem that’s not really addressed The thing that meat consumption correlates with most is not living a healthy life and ignoring doctor’s recommendations. Smoking, not exercising, etc. Eating meat made us human - why would it be killing us? Dr. David Klurfeld: Red meat is somehow blamed for a multitude of varying diseases and cancers. Imagine if one medication was purported to cure all of these disparate things? It’s just not plausible You can get half your daily requirement of protein in just 3.5 ounces of meat Dr. David Klurfeld: there are 8 essential amino acids which are in animal foods but absent in all plant food
