Too fine food on the one hand causes excess fat and heat energy, but also causes the lack of some nutrients. For the health of our whole life, we should pay attention to eating more coarse grains when we are young, and we can often give advice to our parents on our own initiative. This is not only related to our own health, but also beneficial to our parents.

Second, breakfast should not be sloppy.

Many of us skip breakfast every morning just to sleep for more than ten minutes. There are also some people who eat it, but they just deal with it casually and don't pay attention to breakfast at all.

We are in the period of growth and development, with faster energy consumption, less stored nutrients and more timely supply of nutrients. Therefore, breakfast needs to be eaten well and full. Because many people don't eat breakfast or eat too little and it's not good, they will feel exhausted from 10 to10 every morning, and their brains will not concentrate easily, which will affect the class effect. Even some individuals may have symptoms of hypoglycemia such as dizziness, dizziness, cold sweat, rapid heartbeat, and even syncope, which directly affects their health.

Third, eat more fruits and vegetables.

Many of our primary and middle school students are constipated because they eat too much animal food and flour and rice, but not enough vegetables and fruits. The harm of constipation to human body lies not only in making people feel abdominal distension and discomfort, but also in the pain of inconvenient defecation. Moreover, harmful substances in feces will be absorbed excessively, and harmful bacteria in intestines will multiply in large numbers. Damage to the body 2 1 century, in order to avoid the old way of unscientific diet and reduce "diseases of wealth" such as obesity, diabetes, heart disease, hypertension and cancer, nutritionists appeal to the public to adopt scientific diet methods. The main points are as follows:

(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 required heat energy and heat energy sources, amino acid balance, fatty acid balance, acid-base balance, vitamin balance and inorganic salt (macro elements and trace elements) balance.

(2) Eat dark food: Generally, natural food with deep color has high nutritional value, contains a variety of vitamins, trace elements and inorganic salts, and has a health care effect on the human body. Excessive consumption of light-colored natural foods is harmful to human health, such as light-colored vegetables, sugar (refined sugar), salt (refined salt of Emperor J) and polished rice.

(3) Diversity: Any kind of natural food can't provide all the nutrients the human body needs, so it can't be partial eclipse. 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) Don't eat thick food: 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 collocated, and coarse grains should be eaten in 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. .
