1) Nutrition should be balanced: The proportion of various nutrients taken in should be appropriate, and the intake should be balanced with the body's needs.

That is, the balance of required heat energy and heat energy sources, amino acid balance, fatty acid balance, acid-base balance, vitamin balance and inorganic salt (macroelements and trace elements) balance.

?(2) Eat dark-colored foods: Generally dark, rich-colored natural foods have high nutritional value, contain many vitamins, trace elements, and inorganic salts, and have health care effects on the human body.

Eating too much light-colored natural foods is harmful to human health, such as light-colored vegetables, sugar (refined sugar), salt (Jingdi J's salt), refined rice, etc.

?(3) Variety of varieties: It is impossible for any natural food to provide all the nutrients needed by the human body, so there should be no partiality.

Regular meals must include cereals, potatoes, animal foods, soybeans and their products, vegetables, fruits, etc. every day.

The same type of food should also be frequently changed into different varieties, and it should be eaten in combination with a variety of non-staple foods and snacks.

? (4) Don’t eat thick foods: greasy foods such as roasting, roasting, frying, and deep-frying are difficult to digest and absorb in the human body. They not only increase the burden on the gastrointestinal tract, but also destroy the natural flavor.

Food that is too salty and greasy is a predisposing factor for high blood pressure and cardiovascular disease.

Overly sweet foods are closely related to obesity, diabetes and cardiovascular disease.

?(5) Food matching should be scientific: staple food, non-staple food and snacks should be reasonably matched, and coarse and fine grains should be eaten in combination.

The proportions of carbohydrates, fats and proteins are generally 58%, 30% and 12%. At the same time, full attention should be paid to the intake of trace elements and dietary fiber.

?(6) Eat natural and harmless foods: It is recommended to eat natural foods.

Food raw materials and auxiliary materials for food production, including pigments, spices, seasonings and additives, should be natural substances rather than artificial chemical compounds.

?The scientific diet method can be summarized in 16 words: Pay attention to nutrition, pay attention to health care, strive to be scientific, and ensure hygiene.
