#09 – Cholesterol Deficiency, Eating for Mental Health, Optimizing the Carnivore Diet, and Benefits of Inflammation with Chris Masterjohn, PhD

Despite a shifting scientific landscape, dietary cholesterol is still a hotly debated topic. Joe Rogan and Chris Kresser eat eggs every day, while the plant-based community still loves to highlight the supposed dangers of dietary cholesterol. High cholesterol has historically been associated with poor health, but is there a range where cholesterol levels get too low? Our guest in this episode of the podcast believes the combination of a genetic predisposition combined with a strict vegan diet caused him to develop a dangerous cholesterol deficiency. A former assistant professor of Nutrition Science at Brooklyn College, Chris Masterjohn, Ph.D. is one of the smartest minds in nutrition.

Chris shares a fascinating story of how going vegan caused him to develop nutrient deficiencies which led to a battle with mental illness and anxiety. Chris’ subsequent focus on nutrient-dense, animal-based foods restored his health and changed his perspective on how the foods we eat play a large role in cognitive function. We cover a wide range of topics with Chris and he takes a number of controversial positions in this episode, including who shouldn’t eat eggs, nutrient deficiencies that are most likely to arise on a carnivore diet, whether “fancy” blood testing metrics like LDL-P are necessary to gauge cardiovascular health, why some people fail on vegan diets and much more.

Discussion:

There are actually quite a few studies which have found an association between strict Vegan diets and issues with mental health. This is NOT to say that all, or even most, Vegans and Vegetarians are depressed. However, there is growing evidence that mental illness may be a bi-product of Vegan diets for some people. The issue is well summarized in this blog on the Psychology Today website. We also touched on some of these issues in our episode with Dr. Kahn.

This is a good article discussing the concordance / discordance issue for LDL-P and why measuring LDL-P is important.

Here is the commentary I discuss with Chris by a physician who believes LDL-C greater than 190 mg/dl can be a sign that a patient may have undiagnosed sitosterolemia.

    Another great interview!

    It’s always interesting to hear what Chris has to say and I think he has the most well-balanced overview of nutrition.
