In summer, high-temperature and hot weather can easily cause food to spoil and deteriorate. People can easily cause intestinal diseases and food poisoning after eating. Therefore, consumers must take precautions and pay attention to summer diet hygiene.
First, daily attention
1. Choose products correctly, and don't try to buy foods that are of low quality. Try to go to large shopping malls to buy foods produced by regular companies. When purchasing foods, check the outer packaging labels to see if the contents of the labels are complete and exceed the shelf life; buy foods marked with the QS mark; buy meat, poultry, aquatic products, etc. When fresh foods are inspected, in addition to careful inspection of the labels, it is also necessary to check whether there are swelling bags, color changes, odors, etc.
2. Try not to eat raw or unheated food. Fish, shrimps, crabs, snails and other meat and aquatic products must be thoroughly cooked before they can eat; they do not drink raw water or eat raw vegetables; they do not use containers filled with fresh aquatic products to hold other directly imported foods. Fresh water products, such as cutting tools and cutting boards, must be cleaned and disinfected before they can be reused; do not eat dead shrimp, snails, soft-shelled turtles, crabs and other aquatic products; refrigerators must be strictly separated from the storage of raw cooked food.
3. Eating cold drinks can have a cooling effect, but it cannot be eaten too much. Because of the high temperature, most of the body's visceral blood vessels are in a state of relaxation. After eating a large amount of cold drinks, it will cause blood vessels to shrink rapidly or even cause paralysis, which can easily lead to abdominal pain, diarrhea and other symptoms.
Second, beverage knowledge
1. Coke Beverage: Cola taste is sweet and stimulating. Many people like to drink Coke in the summer, but Coke contains higher caffeine, and caffeine is a central stimulant that stimulates the increase of gastric acid secretion and makes the body's brain excited and quick to breathe. Heart rate is faster, so children and those who often suffer from insomnia should not drink.
2. Juice drinks: Juice drinks are divided into pure juice drinks and juice drinks. Pure fruit juice drinks are rich in nutrients, and the calories are low for most people to drink. However, pure summer juice drinks are prone to deterioration, and they must be taken care of during storage. People with more gastric acid secretion and diabetics are not suitable for drinking pure juice drinks. Fruit juice drinks are made from certain pure fruit juices plus coloring matter, sugar and water. The harm of artificial colors cannot be ignored. In particular, children often drink beverages containing artificial colors. Fruit juice drinks contain more sugar, often drinking can lead to obesity.
3. Tea beverages: Tea beverages contain tea tannins, tea polyphenols, and other ingredients that have a health-care effect on the human body. In addition to thirst-quenching, diuretic and anti-heating cooling effect, Changyin also has the effect of preventing cardiovascular diseases, losing weight and bodybuilding. However, the polyphenols in tea beverages have a certain convergence effect on the gastrointestinal mucosa, so constipation patients will increase constipation if they drink it. People with neurasthenia or insomnia are also unfit to drink. Alkaloids in tea inhibit the absorption of calcium in the duodenum, and can also lead to calcium deficiency and osteoporosis. Theophylline in tea beverages causes the gastric parietal cells to secrete a large amount of gastric acid, and hyperacidity inevitably affects the healing of ulcers. Therefore, people with ulcers should not drink.
4. Pure water: It is a colorless, odorless drink that promotes energy release and metabolism. Its osmotic pressure is close to normal saline, which is beneficial to cell absorption. However, there is no mineral in pure water and it cannot prevent cardiovascular and cerebrovascular diseases. Therefore, when drinking pure water, it is necessary to add more minerals and eat more foods rich in calcium, magnesium, and potassium. High-quality pure water is clean, colorless, transparent, free of suspended solids and sediments, non-viscous and odor-free.
Third, cold drink knowledge
Cold drinks include popsicles, ice cream, ice cream, and ice, which are the best-selling foods in summer. Buy cold drinks must choose the regular manufacturers to obtain QS certified products, do not buy unlicensed manufacturers of "three no" products.
1. Ice cream: High quality ice cream is cool and delicate, sweet and palatable. It has unique aromas of various fragrances, uniform milky white or uniform color consistent with its flower variety, no holes with a diameter of more than 1.5cm, and no freeze fastening. phenomenon.
2.
