For a long time, the role of dietary fiber was not significant in the digestive system. And only a few decades ago it was recognized that without them a person cannot exist. Despite the fact that fiber itself does not contain any vitamins or minerals, it is absorbent and removes harmful substances and toxins from the body.
Instructions
Step 1
Dietary fiber reduces the risk of developing diseases of the cardiovascular system. Numerous studies by European scientists have proven the fact that people who systematically consume fiber are less susceptible to diseases such as heart attacks and strokes.
Step 2
Normalization of the digestive system directly depends on the presence of dietary fiber in food. At their core, they are prebiotics that feed the beneficial bacteria in our gut. They contribute to the normalization of stool, carry out the synthesis of vitamins and useful microelements, and also maintain a good state of immunity.
Step 3
Dietary fiber reduces blood cholesterol levels and thereby protects against atherosclerosis and vascular wear. The fact is that cholesterol forms bile acids, which, together with bile, are excreted into the digestive tract. Some of them are able to be absorbed back and form cholesterol again. Dietary fibers inhibit the process of their absorption and thereby protect our blood vessels.
Step 4
Recently, research has shown that fiber can prevent the development of malignant tumors. This is especially true for colon cancer, as well as breast and ovarian cancer. In this case, dietary fiber simply does not allow carcinogens to be absorbed and affect the activation of cancer cells.
Step 5
And, of course, fiber is simply irreplaceable for losing weight. Firstly, it is able to retain water in the stomach and thereby increase the volume of food, but at the same time receive a minimum of calories. Secondly, foods with dietary fiber require thorough chewing, so the feeling of fullness will come on time and you will not be able to overeat. And thirdly, fiber slows down the absorption of sugars, and this in turn helps to maintain blood glucose levels at the required level.
