Carbohydrates (saccharides) are involved in the processprocessing of fats and proteins in the body, help the liver function. For dinner, experts recommend eating protein foods. A carbohydrate-rich food is preferable to take in the morning, as in the afternoon carbohydrate metabolism in the body slows down.
The saccharides in the body are absorbed in the form of glucose.Specialists share fast and slow carbohydrates, depending on the rate of cleavage and conversion to glucose. The speed measurement is carried out by a special indicator - the glycemic index (GI). Slow carbohydrates have low GI. These products are considered useful. These include, in particular, unrefined rice, pasta made from whole grains flour, porridge (except manna) and other slow carbohydrates. The list can also be supplemented with bread of coarse grinding.
Products with a low glycemic index(less than forty) contribute to a gradual increase in glucose in the body. This, in turn, prevents sharp jumps in blood sugar levels, as well as a rapid change of mood for unknown reasons. Thus, experts advise to use slow carbohydrates to maintain calm.
An important is the process of digestionproducts with a lowered glycemic index. Slow carbohydrates begin to be assimilated in the process of chewing food thanks to the enzyme contained in the saliva.
Products that have elevated glycemicindex, not so useful. Of course, they are not poison, but experts do not recommend them every day. It should be noted that, along with desserts, pastries and other products, alcohol is also classified as "fast carbohydrates." This group should be added to mature bananas, white bread, turnips, mashed potatoes and baked potatoes, melon, fritters and the like.
Thus, experts recommend that allproducts, the glycemic index of which is more than sixty, count for "festive food." This will not only help maintain the figure. This attitude to the products will help the body. The fact is that fast carbohydrates have a detrimental effect on the pancreas involved in the production of insulin. This changes the concentration of sugar in the blood, and mood.
Slow carbohydrates are especially important in the winter. In cold weather, saccharides contribute to an additional stimulation of the production of a special hormone, serotonin, responsible for a good mood.
Separate place in the carbohydrate classification is occupied by such products as sugar, fruits and vegetables.
One of the varieties of carbohydrates is fiber ("dietary fiber"). Sometimes it is insoluble and soluble.
In fruits (for example, pears and apples) contains pectin. It is a soluble dietary fiber that helps lower blood cholesterol levels and slow the digestive process.
Insoluble fiber is considered to be the husk of cereals.It is not digested in the body and goes unchanged in an unmodified form. These dietary fibers prevent the appearance of constipation, normalize digestion, reduce the likelihood of cancer in the colon.
It should be noted that the fiber is contained only in plant products. In addition to improving the work of the digestive tract, dietary fiber stimulates lipid (fat) metabolism.
Another sugar product is carbohydrate.Modern industry produces it so pure that there is nothing but calories in it. It should be noted that sugar contributes to the excretion of calcium from the body. Thus, lovers of sweet can not only gain extra pounds, but also get osteoporosis.
Dietitians advise to limit the consumption of sugar to 30-35 kilograms per year, given that it is now contained in almost all products.
