Nutritious meal, originally used in hospitals, means preparing diet according to patients' physical needs, so that patients can recover as soon as possible. Later, this concept was introduced to rehabilitation, health care, health preservation and other fields. The latest use is put forward for school children in remote areas who have problems eating.
Food provides human energy, while physical activity consumes energy. The human body is like a bank. The energy and nutrients necessary for the human body, such as fat, carbohydrate and protein, are equivalent to funds, and the more funds stored, the better. The human body needs to consume energy every day, but eating more than the amount consumed by the human body, so fat is constantly accumulating in the human body.
Extended data:
After the shell of brown rice is removed, the inner layer is chaff layer, which accounts for about 5% of rice and is mainly composed of protein and vitamins. The white fat part is endosperm, which accounts for about 92% of the rice volume, and the main component is starch; The top of rice is germ, which accounts for about 3% of the grain. It is rich in B vitamins and vitamin E, and also contains a lot of protein, fat, carbohydrates and various minerals.
The nutrients in each part account for 90% of the whole rice, 20% of the bran layer and 0/0% of the endosperm/kloc. Brown rice in nutritious meals preserves chaff layer, endosperm and germ, and retains most nutrients. This is different from the refined white rice and refined white flour we usually eat. White rice and white flour remove the bran and germ rich in protein, minerals and vitamins, leaving only the endosperm with little nutrition.
Reducing sodium intake can reduce blood pressure and the risk of chronic diseases related to blood pressure without side effects on blood lipid and renal function. China recommended 2.2 grams of sodium in the past, but this time, adults are advised to control their daily sodium intake below 1.5 grams, which is about 5 grams of salt.
Potassium can prevent stroke and help normal muscle contraction. Potassium also has the effect of lowering blood pressure when high sodium intake leads to hypertension. Healthy people will automatically excrete excess potassium, but patients with kidney disease need to control their potassium intake. People in China don't pay enough attention to potassium. In the past, the recommended amount of nutrition society was 2 grams of potassium per day for adults.
Vitamin C is one of the important antioxidant nutrients necessary for human body. Many studies have shown that high levels of vitamin C in the body can help prevent coronary heart disease, stroke, cancer and death from different causes. Previously, the Institute of Nutrition recommended that adults take vitamin C 100 mg every day; Now, in order to achieve the effect of preventing chronic diseases, the Nutrition Society has set the recommended amount as 200 mg of vitamin C per day for adults.
