1. Dietary principles
1. Pay attention to nutritional balance. Pupils should eat all kinds of food, fruits, vegetables, fish, eggs, milk, etc. in their daily diet, and don't be partial to food.
2. Eat more soy products. Beans are rich in high-quality protein with high nutritional value, which is cheap and easy to digest.
3. chew slowly. Don't eat too fast, especially young children, and chew food carefully, because chewing more is beneficial to improve the digestibility of food and protect the stomach.
4. Don't eat too much. Eating too much will hurt the stomach and reduce the digestibility.
2. Precautions for purchasing food
1. Do not buy food sold in the open air. Because the ingredients of all kinds of food are very complex, after sun exposure, photochemical and exothermic decomposition, it will cause internal changes and deterioration.
2. Don't buy food with incomplete packaging labels. The national Food Hygiene Law clearly stipulates: "The name of the product, the name of the factory, the address of the factory, the date of production (batch number or code number), specifications, formula or main ingredients, shelf life, eating method or using method should be clearly printed on the food packaging." Generally, the above situation will not occur if the label content is incomplete and unclear, and the quality is not guaranteed, and the packaged food that has passed the inspection will not appear. Therefore, it is found that this kind of food is not suitable for purchase.
3. Don't buy food with abnormal sensory characteristics. Abnormal sensory characteristics refer to the phenomena of off-taste, discoloration, precipitation, turbidity, impurities, flocs, mildew, insects, caking, foreign bodies, rancidity, stickiness, corruption and deterioration. No matter what kind of food, it has its own color, fragrance, taste and shape, and the products that are not qualified in sense are the manifestations of deterioration.
4. Don't buy fake or adulterated food. Fake, fake and adulterated food refers to some illegal means such as adulteration, substitution, extraction, whitewashing, mixed filling, counterfeiting, etc., which reduce the quality of food, and some even carry poison, seriously endangering the health of consumers.
