Current definition of dietary fibres created by AACC (American Association of Cereal Chemists) sounds: "Dietary fiber is the edible

parts of plants or analogous carbohydrates that are resistant to digestion and absorption in the human small intestine with complete

or partial fermentation in the large intestine. Dietary fiber includes polysaccharides, oligosaccharides, lignin, and associated plants

substances. Dietary fibers promote beneficial physiological effects including laxation, and/or blood cholesterol attenuation, and/or
blood glucose attenuation

Nutritionists recommend to eat about 30-40 grams of fibre daily, while on average we eat only 15 grams. You can cover missing

volume by changing your diet. Eating high amounts of food rich in ballast substances reduces risk and frequency of appearance of

many diseases and pathological conditions such as arteriosclerosis, diabetes, lingering proctostasis and some kinds of cancer.
