Nutritional meals, originally used in hospitals, refer to preparing meals according to patients' physical needs, so that patients can recover as soon as possible. Later, this concept was introduced into rehabilitation, health care, health preservation and other fields. The latest use is proposed for school children with dietary problems in remote areas.
Food provides human energy, while physical activity consumes energy. The human body is like a bank. Energy and nutrients necessary for human body, such as fat, carbohydrate, protein, etc., are equivalent to funds, and the more funds are stored, the better. The human body needs to consume energy every day, but it eats more than it consumes, so fat keeps accumulating in the human body.
Extended data:
After hulling of brown rice, the inner layer is chaff layer, accounting for about 5% of rice, which is mainly composed of protein and vitamins. The white fat part is endosperm, accounting 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 10% of the endosperm. The brown rice in the nutritious meal retains the husk, endosperm and germ, and retains most of the nutrients. This is different from the refined white rice and refined white flour we usually eat. White rice and flour are stripped of bran and germ rich in protein, minerals and vitamins, leaving only 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 intake in the past, but this time it is suggested that adults should control their daily sodium intake below 1.5 grams, that is, about 5 grams of salt.
Potassium can prevent stroke and help normal muscle contraction. When high sodium intake leads to hypertension, potassium also has the effect of lowering blood pressure. 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 caused by various reasons. Previously, the Institute of Nutrition recommended that adults take vitamin C100 mg every day; Now, in order to achieve the effect of preventing chronic diseases, the Nutrition Society has set the recommended amount of vitamin C as 200 mg per day for adults.
