Dr Burkitt (1911-1993) is credited with highlighting the role of dietary fiber and giving it a prominent place in our collective consciousness. A biography titled The Fiber Man was published in 1985.
Dr Burkitt was trained as a surgeon. He spent many years in Africa. In 1960s and 1970s, he realized that several modern chronic lifestyle conditions which were commonplace in the West were actually rare in Africa! Which diseases? Atherosclerosis, coronary heart disease, adult-onset diabetes, gallstones, bowel cancer, breast cancer, hemorrhoids, varicose veins, diverticulosis, constipation, and so on. He also observed that the incidence of many of these conditions was low in the West prior to the First World War (1914-1918). However, by 1960s and 1970s, the incidence of these diseases was skyrocketing! And it was skyrocketing in both white and black populations. That led him to believe that lifestyle factors were at play. But what exactly were these lifestyle factors? Dr Burkitt believed that the main factor was the shift away from the unprocessed plant-based diet in rural Africa towards a Western diet rich in animal products and processed foods.
An unprocessed plant-based diet, commonplace in rural African communities, is naturally rich in fiber. In fact, dietary fiber is found only in plants! Animal products (meat, fish, eggs, milk and dairy products) have zero fiber. Whenever we consume an animal product, we lose the opportunity to consume fiber!
