Carbohydrates are also called sugar. Usually the staple foods we eat, such as steamed bread, rice, noodles, bread, etc., belong to sugar substances. All kinds of foods contain carbohydrates, but the value of carbohydrates in these different foods is different for us. But all carbohydrates are made of sugar.

According to the speed at which the human body absorbs sugar, we can be divided into three categories.

1. Monosaccharide: such as sugar and glucose (the sugar in fruit is mainly glucose and fructose, which belongs to monosaccharide).

2. disaccharides: such as sucrose, lactose and maltose (sucrose in brown sugar and white sugar and lactose in milk are disaccharides).

3. Polysaccharide, starch, glycogen and cellulose (starch contained in rice, flour, corn and sweet potato belongs to polysaccharide).

Monosaccharide has only one basic component, which can enter the blood at the fastest speed and be quickly converted into energy. Glucose enters the blood faster than fructose.

At least 250 grams of carbohydrates a day.

Insulin can break down the sugar produced by carbohydrates, and then stimulate the pancreas to secrete insulin. Therefore, if you eat too little grain and lack carbohydrates, the function of pancreatic B cells will decrease and the secretion of insulin will decrease. If this situation is maintained for a long time, even if the normal diet is resumed in the future, if the insulin secretion in the body can not meet the requirements, the nondegradable glucose will increase the blood sugar, and diabetes will easily occur.

Disaccharides, such as sucrose, are composed of two basic components and split once during digestion. Therefore, it can completely enter human blood in a short time.

Monosaccharide and disaccharide are sugars that can be quickly converted into energy. Monosaccharide and disaccharide are sugars that can be quickly converted into energy.

Polysaccharide is a high molecular carbohydrate which is composed of many molecular monosaccharides bonded by glycosidic bonds. The monosaccharides that make up polysaccharides can be the same or different. Polysaccharides composed of the same monosaccharide are called homopolysaccharides, such as starch, cellulose and glycogen. Because the longer they stay in the human body, the slower they decompose and are absorbed by the human body.

Have some chocolate before. Don't eat if you don't like it. Don't eat for an hour or two before exercise. Don't eat anything or drink water for half an hour after exercise. Eat when you are calm. There is nothing special to add. Eat more beef if you keep fit for a long time. It's good.

Eat more egg whites and high protein.

Because the principle of muscle growth is minor injury and then repair, the main raw materials for repair are protein and water.

So protein must be enough, and the water must be enough. If you exercise, you should consume no less than 3000ml of water a day.
