To ensure health, you must first pay attention to nutrition. To have adequate nutrition, you must pay attention to the combination of food.

As early as 2000 years ago in the "Huangdi Nei Jing", some people proposed that five grains should be used as food supplements, five fruits should be used as food supplements, five animals should be used as food supplements, and five vegetables could be used as food supplements. These five are pungent, sweet, bitter and salty, and each has its own benefits.

The main nutritional component of whole grains is carbohydrates, followed by plant protein, which can best nourish the vitality of the five internal organs. Fruits are rich in vitamins, inorganic salts and cellulose, which can assist the "five grains" and "five livestock" and enable the human body to obtain more comprehensive nutrition.

Five animals such as meat, milk and eggs are the most nourishing and can nourish the human body’s essence and blood. Supplementing essential amino acids for the human body, complementing the staple food, can promote human health. Vegetables contain a lot of water and vitamins, especially fiber. Generally speaking, a clever combination of grains, fruits, vegetables, meat, milk, poultry, and eggs is the most nutritious and beneficial to health.

Some diseases can also be treated without medication. As long as dietary therapy or drug diet is carried out reasonably and scientifically, you can achieve twice the result with half the effort.

In addition to paying attention to diet, moderate exercise is also crucial. There is a folk proverb that "leaving a mouthful behind when eating, walking a hundred steps after a meal, can live ninety-nine years."

Exercise can promote blood circulation, enhance cardiopulmonary function, improve disease resistance, and maintain health and vitality.

Finally, I will introduce a song about diet and longevity to encourage everyone: If people want to live a long and healthy life, they should eat less late at night. If you eat 80% full, your stomach will be healthy when you are old. If you want people to live longer, eat more tofu and less meat.
