The basis of healthy food is formed by carbohydrates. Only plants are capable to synthesize them. Neither animals, nor the person I am not capable of it. Cellulose is a cover of cages of plants. In a human body there are no enzymes which could split cellulose, but intestinal microflora has such enzymes, in a great gut.
Role of intestinal microorganisms in a human body
Intestinal microbes perform several important functions: constantly keep our immunity in combat readiness; synthesize over ten irreplaceable components of activity (proteins and amino acids); feed an organism with necessary nuriyenta and hormones.
Without cellulose the useful intestinal microorganisms just die and respectively, activity of all organism is broken. Therefore it is necessary to treat microbes with respect and it is obligatory to provide them with food, substances necessary for them, in particular, cellulose or food fibers. They in a large number contain in grain, vegetables, fruit, especially in a cover of grains and their peel. That is why it is so important to use crude, not refined products: porridges from the crude grain, flakes from swaged grain, bread, fruit with a peel. If such food in a diet isn't enough, the deficiency of cellulose can be restored, adding industrially made bran or cellulose to dishes. Adult enough 25-35 g of cellulose a day.
In what processes vitamins and minerals participate
At food, except the essential nutritious ingredients, there are also such substances which are necessary to an organism in very small amount - they are called micronutrients. These are vitamins and mineral substances. Micronutrients are a component of enzymes, hormones, participate in many biochemical reactions of a metabolism therefore they are absolutely necessary for life. The majority of micronutrients in a human body aren't produced, and arrive with food and water.
The long deficiency of separate micronutrients or their constant excessive receipt, causes serious consequences.
The most known example - deficiency of iodine therefore dysfunction of a thyroid gland and - as a result - violation of growth, development, intellectual backwardness develops.
It is important to understand that missing substances can often come to an organism in the form of raw materials. These primary materials as you already guessed, are vegetable cellulose. Consumption of cellulose is a natural and natural way of maintenance of an organism in a healthy state.
