Carbohydrates & fiber
Carbohydrates are the main source of energy. Organic compounds known as sugars composed of carbon, hydrogen and oxygen. Sugars are divided due to the size of the molecules into simple and complex.
The main source of carbohydrates in the diet should be complex carbohydrates. They are, the slower digestion, and it helps to keep a constant level of sugar in the blood.
The best source of complex carbohydrates is bread with wholemeal (whole wheat, graham), vegetables and various types of cereal. The main source of simple sugars: products from purified white flour, sugar, food, sweets, fruit and potatoes.
The carbohydrates in the form of sugar or starch can be found in many types of foods, including milk and fruit where they are accompanied by a lot of very valuable nutrients, such as calcium or vitamin C. But they are also included in products such as sweets and cakes, where nutrient content is negligible, and sometimes they are completely devoid of them, which means that you should limit their consumption. Among the starchy foods you should avoid those that contain purified starches (white bread, rice) and more likely to reach for products containing crude starches such as whole grain bread and pasta, bran or brown rice (these products are also rich in fiber).
Dietary fiber and pectin
Dietary fiber is a building material and supporting plants, and is a major component of cell membranes. It is practically non digestible by the human body, but its presence is necessary in the diet. The role of dietary fiber consists primarily of filling out the gut and stimulate their movement appendicitis (peristalsis), which facilitates the excretion of undigested food.
Sources of fiber are vegetables, legumes and outer layers of cereal grains.
Pectin present in the largest amounts in slots seed unripe fruit, and also in berries, carrots, fruit juice and beet. Regulate the composition of the bacterial flora of the gastrointestinal tract and, like fiber facilitate the excretion of undigested food. Pectin apple treat diarrhea and constipation. Additionally neutralize toxic substances and positively affect cholesterol metabolism.
