With this wide variety of industrialized foods, a large part of the population began to consume more and more processed products, rich in lipids, simple carbohydrates and poor in dietary fiber. This food pattern has a strong association with chronic noncommunicable diseases, such as obesity, diabetes and cardiovascular diseases. Increasingly, there is an association between low fiber consumption and intestinal constipation, hemorrhoids, malignant colon cancer, obesity, glucose intolerance, dyslipidemias and cardiovascular diseases. Food fibers are short or long filamentous substances derived from polysaccharides that form the cellulose molecules. Food fibers are substances of plant origin and do not provide energy, but are fundamental to the functioning of the intestines, although they are not digested by the enzymes present in those organs. Therefore, for those who want to lose weight and take care of their health, fibers are more than an option, they are a necessity. The so-called insoluble fibers , found in whole grain breads, cereals, carrots, cabbage and apple peel, increase intestinal transit , reducing constipation.
