Burkitt attributes low cancer rate to high fiber diet.





Some geographical variations in disease pattern in East and Central Africa.


Important Text:

Thirty years later Dr Dennis Burkitt, while working as a doctor in Africa, discovered that there was a much lower incidence of cancer of the colon among rural black Africans than among Europeans and Americans. He attributed this low incidence to their relatively crude diet. The theory was that fibre hastened the passage of the bowel contents thus allowing less time for cancer-inducing agents to form. This, of course, presupposed that food became carcinogenic in the gut and there was no evidence that it did. Neither was there any evidence that moving food through the intestine at a faster rate decreased the risk of cancer.

Cancer is a metabolic disease where the mitochrondria are no longer able to burn fatty acids and instead rely on fermentation of glucose and glutamine. Ketogenic diets have been used to prevent and cure cancer, as they induce a metabolic stress on cancer cells who cannot use ketones as fuel.
Fiber, also known as dietary fiber or roughage, refers to the indigestible portion of plant foods. It is a type of carbohydrate that cannot be broken down by human digestive enzymes. Instead, it passes through the digestive system relatively intact, adding bulk to the stool and aiding in the regularity of bowel movements. It isn't technically classified as an essential nutrient. The term "essential" in nutrition refers to nutrients that the body cannot produce on its own (or cannot produce in sufficient quantities) and therefore must obtain from the diet
