Fruit makes mans mouth water, and even in absence of hunger he will eat fruit because it tastes so good. The importance of roughage Researchers defend that the lack of vegetable fibres in human diets triggers constipation . Constipation is more dangerous than doctors believe. Meat, eggs, cheese, white bread, cakes and chocolates do not contain any roughage at all . Roughage not only helps the bowel circulation but also acts as a tonic for the stomach and intestine walls, which benefit highly from the corresponding massage and cleaning effects.
Roughage helps to keep a clean colon and a clear mind.
Researches opinion Several scientists and naturalists, including Charles Darwin who gave the theory of evolution , agree that early humans were fruit and vegetables eaters and that throughout history our anatomy has not changed. Many defend that it is possible to spend an entire life living just on vegetables and fruit, as many people do. They say that humans mix meat with some roughage in order to allow a quicker evacuation, because meat contains certain poisonous substances like creatine, leaukomine, xanthine, sarcina, uric acid and some more which are highly toxic, for us- but not for carnivores, for which these substances are necessary, in order to keep them healthy . We do not need the help of meat to ease the digestion of vegetables though. They point out that medical science tries to demonstrate that since the dawn of origins, humans have been omnivorous.
