The amount of food pyramid recommended by China Nutrition Society, in today's fast-paced living environment, due to the pressure of work, environmental pollution and the reduction of nutrients in the food we eat, it is difficult for us to achieve a balanced and sufficient nutrition to ensure the daily needs of the body, so we need to add some extra nutrients to fight against the free radicals brought by pressure and environmental pollution. Professor He Zhiqian, a leading expert of the World Food and Agriculture Organization, gave us several principles to pay attention to when choosing nutritional supplements: first, supplements that are safe, natural and contain various plant factors; second, don't blindly believe advertisements and friends' introductions; and third, have healthy knowledge to choose and distinguish.

The scientific method of eating every day:

1. Oil, salt and sugar are less than 25g (salt and sugar are not more than 6g).

2. Fish, meat, beans, eggs and milk100-250g

3. Vegetables and fruits 500---800g

4. Grains 300---500g (heavy physical strength, light physical strength reduction)

Four elements of human health:

1. Optimistic attitude (it is very important to keep a peaceful attitude at all times for physical and mental health. Anger hurts the liver. Besides the heart, the liver is the lifeblood of the human body)

2. Adequate sleep (8 hours of deep sleep every night, deep sleep means not dreaming, not staying up all night, sleeping till dawn, and human bone hematopoiesis and children's brain development begin at 10 at night, so sugar should rest in bed at 10 at night).

3. Moderate exercise (45 minutes of aerobic exercise every day, it is advisable not to feel tired, but not to exercise excessively. Walking 10000 steps every day, walking faster and sweating slightly is the best aerobic exercise. Cardiovascular and cerebrovascular patients do aerobic exercise for 30 minutes, which is equivalent to producing 200cc immunity by themselves)

4. Balanced nutrition (this step is the most important for the body. With the diversification of food, the human body needs 40 kinds of nutrients every day, and taking 40 kinds of nutrients every day can maintain the most basic nutritional standards of the body. Eat more fruits, vegetables and coarse grains, and choose low-fat and low-cholesterol foods). The bad cholesterol in quail eggs is higher than that in eggs, and squid is higher than quail eggs, which is the highest cholesterol, while eating the cholesterol of an egg every day will not affect blood vessels.

Olive oil is good for cardiovascular system, but don't heat it. Patients with cardiovascular and cerebrovascular diseases can drink a little olive oil.

Second, the human body seven nutrients:

1, water (accounting for 60%-70% of the human body, drinking 2.4 liters of water every day, 1.6 liters is the basic metabolism of the human body every day)

2. Carbohydrate (2%)

3. Fat (15%)

4. protein (20%)

5. Vitamins (1%)

6. Minerals (5%)

7, cellulose (found more than 7 years)
