No, reasonable exercise and a reasonable diet will not make you fat. Teenagers should combine coarse grains with flour and rice. Because of the special demand for nutrients and energy (energy food) in growth and development, and the physiological requirement for hormone level, coarse grains not only hinder the absorption and transformation of cholesterol into hormones, but also hinder the absorption and utilization of nutrients. For example, eating too much "coarse grains" will affect the absorption of protein, inorganic salts and some trace elements, and even affect the human reproductive capacity. So coarse grains should be served with flour and rice.

Coarse grains are simple to process and retain many nutrients that are not found in flour and rice. In terms of nutrients, the content of protein in coarse grains is relatively low, while the content of starch, cellulose, inorganic salts and B vitamins is rich.

Usually eat coarse grains, such as dried beans such as soybeans, red beans, mung beans, black beans and so on. ; Millet, corn, sorghum, oats, buckwheat, wheat bran, etc. Generally, it is solid, and it can be made into a drink with grains, giving people a refreshing feeling.
