As early as 2000 years ago, in the year of Huangdi Neijing, it was proposed to supplement five grains, five fruits, five livestock and five vegetables. These five kinds are bitter, bitter and salty, each with its own merits.
The main nutritional components of whole grains are carbohydrates, followed by protein and protein, which can nourish the qi of five internal organs. Fruit is rich in vitamins, inorganic salts and cellulose, which can assist "five grains" and "five animals" and make the human body get more comprehensive nutrition.
Meat, milk, eggs and other five animals are the most tonic, which can nourish human essence and blood. Supplementing essential amino acids and staple foods can promote human health. Vegetables contain a lot of water, vitamins, especially cellulose. Generally speaking, the ingenious combination of cereals, fruits and vegetables with meat, milk, poultry and eggs is the most nutritious and healthy.
Some diseases can be cured without taking medicine. As long as the diet or drug diet is carried out reasonably and scientifically, we can achieve twice the result with half the effort.
Besides paying attention to diet, moderate exercise is also important. There is a saying in the folk proverb that "you can live for 99 years after eating a bite."
Exercise can promote blood circulation, enhance heart and lung function, improve disease resistance and maintain health and vitality.
Finally, I will introduce a song of longevity in diet, encouraging everyone: people should live a long life, be safe, and eat less at night. Eat to 80% full, and the old stomach will be fine. If you want to live a long life, eat more tofu and less meat.
