Chris Masterjohn — Oxidative Stress & Carbohydrate Intolerance: An Ancestral Perspective

Chris Masterjohn, Ph.D. has just completed his Ph.D. at the University of Connecticut, where his doctoral research focused on the role of oxidative stress in regulating metabolism of methylglyoxal, a major precursor of advanced glycation end products. He created and maintains Cholesterol-And-Health.Com, where he publishes his blog, The Daily Lipid.

The role of carbohydrate in health and disease remains controversial in the ancestral health community. Numerous groups of foragers, pastoralists, and agriculturalists have been found free of the so-called “diseases of civilization” while subsisting on diets rich in carbohydrate, yet clinical trials have shown that low-carbohydrate diets can help reduce disease risk in modernized populations. In this talk I will discuss evidence from my doctoral research suggesting that oxidative stress contributes to carbohydrate intolerance and will review the literature suggesting that oxidative stress is a common cause underlying carbohydrate intolerance in modernized populations. I will conclude by presenting a broad, holistic view of “oxidative stress” that moves beyond “antioxidants” and focuses instead on the density and balance of nutrients in the diet, and the optimization of the hormonal milieu within which those nutrients operate.

The Tarahumara are 94% Vegan. A Hunter-Gatherer Tribe of Marathon SuperAthletes who AVOID Meat & win Long Distance Running Races

These top elite ultra-marathon athletes eat a 75-10-15 nearly entirely plant-based 94% vegan diet and eat 71% of their diet as Grains and are among the healthiest people in the world, with virtually no atherosclerosis, virtually no obesity eating over 75%+ carbs and set Guinness world records in athletic endurance. They are virtually free of many of the diseases plaguing other native hunter gatherer populations such as the Maasai and the Inuit who have among the shortest lifespans on earth.

In contrast the Tarahumara vegan diet based tribe shows virtually none of these meat-based diseases and instead grew to amazing athletic prowess. (See medical study here: Peer-Reviewed Scientific and Medical Sports Nutrition Journal: The American Journal of Clinical Nutrition, 32, April pp. 905-915, 79 . “Food and Nutrient Intakes of the Tarahumara Indians of Mexico” Maria T. Cerqueira, M.S. R.D. Martha McMurry Fry, M.S. R.D. and William E. Connor, M.D — and full Lipid Analysis of the plant based hunter gatherer tribe here: )

Nearly vegan plant-based tribe is healthy. The Eskimo and Maasai meat-eating tribes are now sick and rife with diseases and bad health. 6 Maasai “warriors” who eat a Pastoral Paleo type meat-based diet tried to run the London Marathon. They bragged of chasing a lion before they ran the race. When the News Media reporters showed up this story changed to them claiming they killed several lions. When the race started, 2 of the steak-eating meat-based pastoral paleo diet hunter-gatherers ended up in the Hospital. Two of them had to be taken away in an ambulance. 2 more of them couldn’t finish the race and gave up in the middle. They didn’t make it past the half-way point. They stopped prior to 13 miles and could not go any farther. The last 2 of the maasai slowed down to walking and finally finished the race in a time of almost 5 and a half hours. (To compare, the 98% vegetarian Kalenjin runners who are also from the same country of Kenya but eat a plant based diet usually finish the entire marathon in 2 hours and 15 minutes or faster. The record is 2 hours and 3 minutes. So a vegetarian from the Kalenjin tribe in Kenya could run and finish TWO marathons in the time that one paleo type meat-eating Maasai tribe runner needed to make it to the finish line. Not counting the Masai runners who couldn’t make it to the finish line and ended up going to the hospital.

In contrast, the native aboriginal TARAHUMARA hunter-gatherers avoid meat and eat a 94% vegan practically Anti-Paleo diet bursting full of Grains, Wheat, Corn, Beans and Legumes and have become super-athletes.

The Tarahumara plant-eaters can run distances of up to several ultramarathons, up to an absolutely astounding 400 miles at one time. Their diet is a 96% Vegetarian 94% Vegan Plant-based diet. They eat over 75% of their diet as Carbohydrates, with 12% as Protein and low fat diet of less than 13% Fat. This has resulted in them being one of the healthiest populations on earth with hardly a case of heart disease in their entire population and extreme athletic endurance. Scientists could not find even one case of obesity on their HIGH CARB diet of portions of up to 75% carbs at a time. And they had no cases of diabetes, and no insulin resistance, due to the fact that diabetes is caused by Fat, diabetes and insulin resistance aren’t caused by eating carbs. In fact, a low carb high fat diet will worsen diabetes because it is merely holding back fuel while still exposing pancreating and intra-muscular cells to high levels of the saturated animal fats that caused the insulin resistance and diabetes in the first place, whereas the plant-based diet may prevent insulin resistance or even reverse it due to its healthy high carbs and elimination of harmful saturated animal fat.
