I. Daily Precautions
1. Choose goods correctly, and don't covet cheap food with low quality. Try to buy food produced by regular enterprises in large shopping malls; When buying food, pay attention to check the product packaging logo to see if the logo content is complete and whether it exceeds the shelf life; Give priority to the purchase of food marked with QS mark; When purchasing fresh food such as meat, poultry, aquatic products, etc., in addition to carefully checking the logo, you should also check whether there is bag swelling, color change, odor and other phenomena.
2. Try not to eat raw or incompletely heated food. Fish, shrimp, crabs, snails and other meat birds and aquatic products should be thoroughly cooked before eating; Do not drink raw water or eat raw vegetables; There is no need for containers filled with fresh aquatic products to hold other foods directly imported, and knives and chopping boards processed with fresh aquatic products must be cleaned and disinfected before they can be used; Do not eat dead shrimp, snails, turtles, crabs and other aquatic products; The storage of raw and cooked foods in the refrigerator should be strictly separated.
3. Eating cold drinks can cool down, but you can't eat too much. Because high temperature makes most of the visceral blood vessels in the human body in a relaxed state, eating a lot of cold drinks will cause rapid contraction and even spasm of blood vessels, which will easily lead to abdominal pain, diarrhea and other symptoms.
Second, the common sense of drinks
1. cola beverage: cola tastes sweet and refreshing. Many people like to drink cola in summer, but cola contains high caffeine, which is a central stimulant, which can stimulate the increase of gastric acid secretion, make the human brain excited, breathing faster and heart rate faster, so children and people who often suffer from insomnia should not drink it.
2. Juice drinks: Juice drinks are divided into pure juice drinks and juice-containing drinks. Pure fruit juice drinks are rich in nutrition and low in calories, which are suitable for most people to drink. However, pure fruit juice drinks are prone to deterioration in summer, so we must pay attention to them when storing them. People with more gastric acid secretion and diabetics are not suitable for drinking pure juice drinks. Juice-containing drinks are made of certain pure juice with pigment, sugar and water, but the harm of artificial pigment can not be ignored, especially for children who often drink drinks containing artificial pigment. Juice-containing drinks contain more sugar, and regular drinking will lead to obesity.
3. Tea beverage: Tea beverage contains many ingredients such as tea tannin and tea polyphenols, which has a certain health care effect on human body. In addition to quenching thirst, diuresis and heatstroke prevention and cooling, regular drinking also has the effects of preventing cardiovascular diseases, losing weight and bodybuilding. However, polyphenols in tea drinks have a certain astringent effect on gastrointestinal mucosa, so constipation patients will aggravate constipation if they drink it. People with neurasthenia or insomnia should not drink it. Alkaloids in tea can inhibit the absorption of calcium by duodenum, and also lead to calcium deficiency and osteoporosis. Theophylline in tea beverage makes gastric parietal cells secrete a lot of gastric acid, which will inevitably affect the healing of ulcer surface, so people with ulcer disease should not drink it.
4. Pure water: it is a colorless and odorless beverage, which can promote energy release and metabolism. Its osmotic pressure is close to normal saline, which is beneficial to cell absorption. However, there are no minerals in pure water, which cannot prevent the occurrence of cardiovascular and cerebrovascular diseases. Therefore, when drinking pure water, you should supplement more minerals and eat more foods rich in calcium, magnesium and potassium. High-quality purified water is clean, colorless and transparent, free of suspended solids and sediments, not sticky and odorless.
Third, common sense of cold drinks
Cold drinks, including popsicles, ice cream, ice cream and ice cubes, are the best-selling foods in summer. When buying cold drinks, you must choose products certified by QS from regular manufacturers, and never buy "three noes" products produced by unlicensed manufacturers.
1. ice cream: high-quality ice cream tastes cool, delicate, sweet and palatable, and has the unique aroma of various flavor types, showing uniform milky white or uniform color consistent with its color variety, without holes with a diameter exceeding 1.5cm and without freezing and fastening.
2.
