Nutrition is the foundation of health, and food is the source of nutrition. Our bodies need all kinds of nutrients in food to regulate their physiological functions every day, so it is very important to match food reasonably and evenly. Cereals are the foundation, and the energy we need mainly depends on them. Under normal circumstances, light manual workers should consume 300-500 grams a day. Followed by vegetables and fruits, 400-500 grams of vegetables and 0/00-200 grams of fruits should be eaten every day; Then there are animal foods such as fish, poultry, meat and eggs. The usual ratio is 50 grams of fish and shrimp, 50- 100 grams of meat and 25-50 grams of eggs. In addition, you should consume100g milk and dairy products and 50g beans and bean products every day; And the daily intake of oil should not exceed 25 grams.
We should choose a variety of foods, because one food can't provide enough nutrition. Besides cereals, we should eat more vegetables and fruits. Fruits and vegetables are rich in vitamins and minerals, especially vitamin C and carotene. For people who eat less animal food, they lack the direct source of vitamin A. They can eat more green and orange vegetables to get carotene, which can be converted into vitamin A in the body. Fruits and vegetables are also rich in dietary fiber and are indispensable.
The amount of the above foods should be reasonably matched, not partial eclipse, so as to achieve a balanced nutrition.
