Any dietary approach claiming remarkable health benefits naturally sparks widespread attention. In this article, we scrutinize the validity of one such regimen – Dr. McDougall's dietary framework.
The McDougall Diet
John A. Mcdougall is an American internist who is best known for his book, "Health Without a Prescription, A Styrofoam That Cures". The author's diet has gained immense popularity and has been credited with many health benefits.

Rules of the starch-based diet
The McDougall diet is a diet based on starches, i.e. carbohydrates present not only in cereals, legumes, potatoes. It is a vegan diet devoid of all animal products meat, fish, eggs, milk and dairy products. What distinguishes the McDougal diet from the vegan diet is very strictly limited fat intake. However, fats, not only of animal origin, but also of vegetable origin are not recommended. The basic dietary principles of this diet are: acid-based animal products.
McDougall's diet is indicative
The McDougall diet is a vegan diet. The starch-based diet does not provide enough fat. However, this nutrient is often incorrectly presented as a daily dietary supplement that should be consumed. Although not all of the ingredients in the McDonald's diet appear to be rationally justified. The diet based on starches does not deliver enough fat in a healthy way.
Is this even a starch-based diet? What to eat, what to avoid?
Basing our diet on starch products to obtain beneficial effects, we must at the same time eliminate or limit certain vegetable potatoes.
