Nutrition as a science was developed mainly during the second half of this century and despite its constant evolution there is still confusion about what constitutes a healthy diet. The concept of including fiber in our diets actually took importance over the past twenty-five years. Before she was considered an inert element lacking in relevance, but experimental and epidemiological observations drastically changed this view. It is now accepted each day with greater emphasis than is possible to design diets that help prevent disease. Fiber is the part of plant foods that pass through the intestinal tract without being digested.

Why fibers are not digested in the intestinal tract of man?
Because the molecular structures of various fibers (hemicellulose, cellulose, pectins, mucilages, etc.) are unique and can not be digested by our digestive enzymes.

The enzymes produced by salivary glands, pancreas and intestine have unfolded molecules as a function of protein, carbohydrates and fats and have specificity to act on certain structures. This fact that was never awarded importance was the subject of studies in the seventies in which fiber intake linked to cancer and cardiovascular disease and who achieved a great discovery to test the hypothesis that fiber plays a role very important in preventing cardiovascular disease and certain types of cancer.

It has been shown that wheat bran is important for its function and laxative agent in preventing colon and breast cancers. While oat bran and psyllium prevent cardiovascular disease.
