The contents of the handwritten report on food safety include: balanced nutrition, eating dark food, diverse varieties, not eating thick food, scientific food collocation, eating natural and harmless food, etc.

1, nutrition should be balanced: the intake of various nutrients should be appropriate and balanced with the needs of the body. That is, the balance of heat energy and heat energy sources, amino acid balance, fatty acid balance, acid-base balance, vitamin balance and inorganic salt macro-element and trace element balance.

2, eat dark food: generally dark, thick natural food, high nutritional value, containing vitamins, trace elements, inorganic salts, has a health care effect on the human body. Eating too many light-colored natural foods is harmful to human health, such as light-colored vegetables, refined sugar, refined salt and refined rice.

3, varieties should be diverse: any kind of natural food can not provide all the nutrients needed by the human body, so it is not allowed to generalize. The daily diet must include cereals, potatoes, animal foods, soybeans and their products, vegetables and fruits. The same food should always be changed into different varieties, and it should be eaten together with a variety of non-staple foods and snacks.

4, do not eat thick: burning, roasting, frying, frying and other greasy foods are difficult to digest and absorb in the human body, which not only increases the burden on the gastrointestinal tract, but also destroys the natural flavor. Too salty and greasy food is the inducing factor of hypertension and cardiovascular disease. Too sweet food is closely related to obesity, diabetes and cardiovascular disease.

5. Food collocation should be scientific: staple food, non-staple food and snacks should be reasonably matched, and coarse grains should be combined with flour and rice. The proportions of sugar, fat and protein are generally 58%, 30% and 12%. At the same time, we should pay full attention to the intake of trace elements and dietary fiber.

6. Eat natural and harmless food: advocate eating natural food. Food raw materials and auxiliary materials for food production, including pigments, spices, condiments and additives, should be natural substances, not artificial chemical compounds.

The scientific diet method can be summarized as 16 words: attach importance to nutrition, attach importance to health care, strive for science and ensure hygiene.
