Nutritional imbalance refers to obesity and malnutrition caused by high fat and carbohydrate intake.

Malnutrition refers to the lack of nutrition caused by insufficient food intake, increased demand, excessive loss or obstacles in the process of utilization in the body.

What is overnutrition? Overnutrition mainly includes two aspects: one is obesity; The other is over-nutrition.

Nutritional imbalance: the outstanding performance is that the intake of animal food and fat increases, while the intake of cereals and beans decreases. Due to excess calories, overweight and obesity rates have greatly increased, leading to a significant increase in chronic diseases related to nutritional vector balance.

Therefore, a reasonable food mix can balance nutrition, especially for children and obese people. Reasonable collocation includes coarse and fine collocation, vegetarian collocation, acid-base collocation and so on. Reasonable diet is to choose a variety of foods, so that the nutrients contained are complete and the proportion is appropriate to meet the needs of the human body.

Dietetic experts believe that the most balanced goal of diet: daily diet.

55% ~ 60% of grain heat

Protein 70 ~ 75g (animal protein and soybean protein should each account for 20% ~ 25%).

In order to achieve this nutritional goal, everyone eats 12kg eggs, 15kg milk, 24kg meat, 9kg fish and 18kg beans on average. At the same time, the consumption of vegetables and fruits should be appropriately increased. The supply of vegetable oil and sugar as pure heat energy food is 6kg respectively, and the consumption level of finished grain is stable at around 150kg.
