Analysis:
1, cola drinks: Many people like to drink cola in summer, which tastes sweet and refreshing. However, cola contains high caffeine, which is a central stimulant, which can increase gastric acid secretion, make people's brains excited, their breathing accelerated and their heart rate accelerated, 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 beverage is rich in nutrition, extremely rich in taste and low in calories, which is suitable for most people to drink. However, it should be noted that pure juice drinks are easy to deteriorate in summer. Pure fruit juice drinks are good, but people with high gastric acid secretion and diabetics are not suitable. Fruit juice drinks are made of pure fruit juice, pigment, sugar and water, but the harm of artificial pigment can not be ignored, especially for children who often drink drinks containing artificial pigment, because fruit juice drinks have high sugar content, which can also lead to obesity.
3. Beer: Beer is rich in vitamins, such as vitamin B 1, B2, B6, B 12, folic acid, nicotinic acid, mineral potassium, etc. *** 1 1 minerals, so moderate drinking has the effects of appetizing, improving eyesight, invigorating spleen, quenching thirst and diuresis. The optimum drinking temperature of beer is 8-65438 05℃. If the temperature is too high, it will be rough to drink, and the miscellaneous taste of beer will be easily exposed, while if the temperature is too low, the taste will be uncomfortable and the mouth will feel frozen. Especially when beer is frozen below 3℃, the flavor of beer will change and it is difficult to foam. More importantly, the volume of beer will increase after freezing, which will easily lead to the rupture of the bottle, so don't put the beer in the freezer. Here, I also want to remind everyone that it is not appropriate to eat pickled and smoked food at the same time, do not drink strong liquor, do not drink beer after sweating, do not drink old beer, and do not drink beer for people with high uric acid.
3. carbonated drinks: most carbonated drinks are bright in color and refreshing in taste. The biggest feature of carbonated drinks is that they contain "carbonated gas", which endows them with special flavor and irreplaceable functions of relieving summer heat and quenching thirst in summer. However, carbonated drinks contain no vitamins and minerals. The main ingredients are sugar, pigments, spices and carbonated water, and there are almost no nutrients except calories. Another study shows that drinking carbonated drinks regularly is not conducive to the healthy development of human bones. Teenagers who drink carbonated drinks regularly have three times the risk of fracture as other teenagers who don't drink carbonated drinks regularly. In addition, carbonated drinks contain more sugar, which can easily lead to obesity, especially for children.
4. Tea beverage: Tea contains many ingredients such as tea tannin and tea polyphenols, which has a good health care effect on human body. In addition to quenching thirst, diuresis, heatstroke prevention and cooling, regular drinking also has the effects of preventing coronary heart disease, losing weight and bodybuilding. Therefore, it is best to drink tea in summer, but the polyphenols in tea have a certain astringent effect on gastrointestinal mucosa, so constipation patients will aggravate constipation if they drink tea. People with neurasthenia or insomnia should not drink tea. Because the alkaloids in tea will inhibit the absorption of calcium by duodenum, it will also lead to calcium deficiency and osteoporosis. People with canker should not drink tea. Because theophylline in tea will reduce the activity of phosphodiesterase and make gastric parietal cells secrete a lot of gastric acid. Hyperacidity will inevitably affect the healing of ulcer surface. People with urinary calculi should not drink tea.
5. Pure water: It is a colorless and odorless beverage that can promote energy release and metabolism. Its osmotic pressure is close to normal saline, which is beneficial to cell absorption, and its ability to dissolve fat is much higher than that of ordinary water. However, pure water has no minerals, which can not prevent the occurrence of cardiovascular and cerebrovascular diseases, but will promote 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.
6. Special functional drinks: Now you can often see some drinks with special functions on the market, which have special functions that other drinks do not have. For example, sports drinks are suitable for drinking after strenuous exercise, especially in summer when people sweat a lot. Electrolytes, vitamins and inorganic salts in it can quickly replenish human functions, which is beneficial to energy supply during exercise and physical recovery after exercise. But this drink is not suitable for drinking without exercise and sweating a lot, because the sodium contained in it will increase the burden on the body, causing heart load and blood pressure to rise. Therefore, patients with hypertension should pay attention to their choices. For some nutritious drinks, because the vitamins contained in them are water-soluble and easy to be absorbed and excreted by the human body, they can be drunk in moderation. There are also functional drinks with anti-fatigue, slimming and beauty functions. Some health-care ingredients are added to these drinks, some of which contain LGT and Bifidobacterium proliferation factors, which are safe for the human body to lose weight, and help to tidy up the stomach, promote fat metabolism, detoxify and beautify the face. Special functional drinks need targeted selection.
