First, what problems should students pay attention to when buying food?
1, go to a regular store and don't buy the "three noes" food around the campus and in the streets.
2. Buy food produced by regular manufacturers and try to choose brands with good reputation.
3. Check the product label carefully. Food labels must be marked with: product name, ingredient list, net content, factory name, address, production date, shelf life, product standard number, etc. Don't buy products with nonstandard labels.
4. Whether the food is suitable for your own consumption.
5. Don't blindly follow advertisements. Advertising does not represent science, but reflects the interests of businesses.
Second, what food hygiene habits should students pay attention to?
1, boiled water is the best drink, and some drinks contain preservatives, pigments and so on. And regular drinking is not good for children's health;
2. Develop good hygiene habits to prevent the spread of intestinal parasitic diseases;
3. Wash raw vegetables and fruits before eating to avoid pesticide poisoning;
4. When choosing food, pay attention to the production date and shelf life of the food;
5. Try to eat less or not eat leftovers. If you eat leftovers, you must heat them thoroughly to prevent bacterial food poisoning;

Third, do students eat sweets as much as possible?
Drinks contain high sugar content, and children who eat too much are prone to skin inflammation and various diseases. Excessive intake of sugar will also produce a lot of acidic substances, thus breaking the normal acid-base balance of blood and turning children into acidic people. Medical data show that 70% of diseases occur in people with acidic constitution, which undoubtedly makes children the "number one bed for slimming in Korea". In addition to the above functions, many drinks also lack protein and fat necessary for children's development. Drinking too much will affect children's eating dinner and cause malnutrition, so it is best not to drink more than 100 ml every day.

7. Don't eat food that you know that preservatives or pigments have been added, but you are not sure whether the added amount meets the food hygiene and safety standards.
6. How to distinguish the shelf life and shelf life of food?
The so-called shelf life (the best edible period and the shortest applicable date) refers to the period specified in the label to maintain the quality under storage conditions. Shelf life (suggested last edible date) refers to the expected date of termination of consumption under the storage conditions specified in the label, after which the product is no longer edible.
Seven, how to buy drinks correctly?
First of all, it depends on whether the label, QS mark, production date, shelf life, factory name and address are complete, and whether the ingredients in the ingredients meet the standards of this kind of beverage.
Secondly, choose the products that have been produced recently. When buying carbonated drinks, try to choose products that have been produced recently and whose tanks are hard and not easily deformed.
Third, the choice of drinks should vary from person to person. Fruit juice drinks have certain nutrients and are suitable for teenagers and children, but they cannot be drunk in large quantities for a long time or at one time.
