course, reasonable limitation of the amount of fat entering the body with food is a health effect and causes a reduction of excess body weight.However, in this case it is better to stick to the "golden mean", because the lack of fat in the diet leads to some undesirable consequences.The fact that fats perform many vital functions in the human body.These substances are part of cell membranes, form a protective layer around the internal organs, prevent the body from both the hypothermia, and from overheating.Therefore, the lack of fat in the diet is harmful to human health.
adults should be consumed with food is the amount of fat, which fully meets the needs of human energy, but at the same time does not lead to the deposition of excess fat tissue.This amount is for adult women is about 90 - 115 grams per day, depending on the state of her health, physical activity and health.Vegetable oil in the daily diet should be at least 20 - 25% of the total fat, butter - 25%, margarine and cooking fats - 15 - 20
In no case can not be completely ruled out fat from the diet, as to what good it does not.Even vegetarians consume at least 25 - 30 grams of fat a day, due to their content in vegetable products.The disadvantage of this component in food leads to the appearance of dryness of the skin and pustular diseases of a skin appearance, hair loss, disruption of the gastrointestinal tract.With a lack of fat is reduced resistance to infectious diseases, interfere with the normal flow of biochemical reactions involving vitamins A, E, C, develop deficiency symptoms of food components.It is especially dangerous to limit the use of fats in food to people with pre-existing metabolic disorders.
Lack of dietary intake in the human vegetable fats (oils) cause physiological damage lipids that make up cell membranes.In this case, it changes the permeability of membranes and their strength of binding to different enzymes which, in turn, leads to a change in enzyme activity and thereby disrupts metabolism.
When at physical education and sports body is exposed to intense physical exertion, it leads to the development of a small oxygen deficiency.In this case, the amount of fat in the diet is slightly reduced by increasing the amount of carbohydrates.
Limit consumption of fats is also recommended for certain diseases - atherosclerosis, pancreatitis, hepatitis, cholelithiasis, acute enterocolitis, diabetes and obesity.
Thus, the desire to create a special lack of fat in the diet biologically totally unjustified and, moreover, is extremely dangerous for human health.
