The front end of the time there is a region of the Bureau of Industry and Commerce released to consumers some drinks (including mineral water) arsenic content exceeds the standard, some barrels of water bacteria content exceeds the standard. These prompt us to choose drinks need to think twice. In fact, it is these drinks hygiene and heavy metal content is normal, we should not drink as much as plain water for a long time, or even use drinks instead of plain water. Here we talk about the harm caused by drinking too many beverages to the human body. Such as the popular carbonated drinks is what we call soda, is a soft drink filled with carbon dioxide gas. In the market, a variety of flavors, varieties are very rich, especially by the young people’s welcome. However, experts remind you that you should drink carbonated beverages in moderation, especially young people should not be addicted to it, because its side effects on the human body will greatly exceed the sensory stimulation it brings. Hou Xiaohua, Department of Gastroenterology, Wuhan Union Hospital, said carbonated beverages contain carbon dioxide, which can stimulate gastric juice secretion, make you feel bloated, reduce your appetite, and reduce your daily diet intake, resulting in insufficient nutrient intake and affecting normal growth and development, learning performance, work performance and health. Carbonated beverages contain sugar, but only the same amount of calories, but a big difference in nutrients, because sugar only contains calories, but no other nutrients, is empty calories of empty food or junk food, often drinking, will accumulate less into more, so that weight gain, long-term fatty liver will also occur; in addition, sugar also has a negative impact on dental health. Another component of carbonated drinks, phosphoric acid, it will reduce the absorption of calcium in the body, affecting the normal development of bone growth and height. Children and adolescents in the growth period need sufficient calcium for the normal growth and development of bones, so it is not advisable to drink carbonated beverages. In addition, phosphoric acid also hinders the absorption of iron, which is one of the main materials for the production of blood, and once iron is not enough, it will cause iron deficiency anemia. Caffeine contained in various colas Caffeine will stimulate the heart muscle contraction, accelerating the heartbeat and breathing; it will stimulate the secretion of gastric acid, hurting the stomach and intestines; with diuretic effect, the elderly are prone to the risk of dehydration. If consumed in excess for a long period of time, i.e. more than 200 mg of caffeine per day, chronic toxicity such as indigestion, headache, insomnia, nervousness, shaking, irritability, and rapid heartbeat can occur. Some functional drinks containing vitamins and electrolytes, such as Red Bull and Pulse, do not have much practical significance if the body is healthy and normal, or if there is no physical exertion and no need to replenish energy, except for quenching thirst by drinking too much of these drinks. In addition, these drinks are more suitable for specific groups of people and adults who are physically exhausted, while children are in the developmental stage and exercise less, so if these ingredients are supplemented in excess, it will increase the burden of self-regulation of children, and excessive drinking will also exceed the capacity of children’s digestive system and kidney, liver and nervous system. For children, often drinking large amounts of these drinks instead of drinking porridge, drinking water and eating fruit will seriously affect their health. So, how do we choose the right beverage for ourselves? When selecting drinks, it is worthwhile to look at the ingredients stated on each drink, and according to the different nutrients, the body needs to be supplemented according to the ingredients, so that the corresponding effect can be achieved. Such as tea drinks, tea contains tea tannins, tea polyphenols and other ingredients, has a very good health effect on the human body. In addition to thirst quenching, diuretic and summer cooling effect, regular drinking can also prevent coronary heart disease, gain weight loss and bodybuilding effects. Juice drinks are not high in calories, such as orange juice, orange juice, fresh fruit into juice, adding a lot of vitamins and other nutrients, extremely rich taste, is the ideal drink. The beneficial bacteria of the “probiotic factor” milk drink, is due to the “probiotic factor” in the daily drinking to solve the absorption of calcium, iron, zinc and other nutrients. However, experts remind that the preferred drink is water. Fresh plain water is the best choice, plain water is the natural state of the water after multi-layer purification process, boiling, the microorganisms in the water has been killed in the high temperature, the calcium, magnesium elements in the boiling water is very beneficial to health, and contains calcium, magnesium and other elements of hard water has the role of cardiovascular disease, and water does not contain heat. Note that when you take plain water in summer, you can take some salt in moderation. In short, fresh plain water is the last method of hydration for the body, various juices can be supplemented as needed, while carbonated drinks should be controlled.
