Influence of diet on personal nutrition and health

Human life must be maintained by diet. People's quality of life and mental psychology are closely related to diet and nutrition. People's intelligence, physical strength, learning ability, sports ability, disease prevention ability, rehabilitation ability, reproductive ability, life expectancy, height and weight are also inextricably linked with nutritious diet.

Unbalanced nutrient intake can cause many diseases. Therefore, reasonable nutrition and balanced diet are important measures to prevent diseases.

For the human body, nutrition is the whole process of ingesting food from the outside, digesting, absorbing and utilizing the substances needed by the human body in food to maintain life activities. These substances needed to maintain the normal growth, development and metabolism of the body are called "nutrients".
