Teeth of teenagers are corroded, and drinking sparkling drinks (coke, soda) is one of the main reasons.
Composition and harm of cola
Carbonated drinks-affect your calcium and iron.
Carbonated drinks include all kinds of soda, flavored soda, cola, flavored cola, and all kinds of carbonated drinks.
There are four reasons why carbonated drinks should not be drunk often:
Carbonated drinks contain gas, namely carbon dioxide.
Carbon dioxide can stimulate the secretion of gastric juice, and hyperacidity can easily lead to bloating, loss of appetite and reduction of daily food intake. Insufficient intake of nutrients in diet will affect normal growth and development, learning effect, sports performance, work performance and health.
Carbonated drinks contain sugar.
A can of 355 c.c cola contains about 35 grams of sugar, equivalent to 140 calories, equivalent to half a bowl of rice. However, only the calories are equal, but the nutrients are quite different, because sugar has only calories and no other nutrients at all. It is empty card food or junk food with calories. If you drink regularly, every little makes a mickle, you will gain weight and easily develop a bad eating habit of being sweet. You only like sweet water, not boiled water. In addition, sugar has a bad effect on dental health.
Phosphoric acid, another component of carbonated drinks
Phosphoric acid can reduce the absorption of calcium in the body and affect the normal development of bone growth and height. Children and adolescents in growth and development need enough calcium to make bones grow and develop normally, maintain good bone metabolism and achieve the best bone density, so it is even more inappropriate to drink carbonated drinks. In addition, phosphoric acid will hinder the absorption of iron, which is one of the main substances for making blood. Once iron is not enough, it will cause iron deficiency anemia. Children who are growing fast need enough iron to make blood quickly. Especially adolescent girls, the demand for iron is higher, because a lot of iron is lost every month during menstruation. Therefore, girls who love carbonated drinks are more prone to iron deficiency anemia.
Caffeine contained in various colas.
Caffeine can stimulate myocardial contraction and accelerate heartbeat and breathing; It will stimulate gastric acid secretion and harm the stomach; It has diuretic effect, and the elderly are prone to dehydration; Long-term drinking will be addictive. Once you don't drink it, you will feel uncomfortable, listless or have a headache. If you drink too much for a long time, that is, caffeine exceeds 200 mg every day, there will be chronic poisoning phenomena such as indigestion, headache, insomnia, nervousness, trembling, irritability and rapid heartbeat. Caffeine is found in cola, tea and coffee. A can of 355 c.c cola contains 65 mg of caffeine, a can of 350 c.c oolong tea contains 80 ~ 120 mg, and a cup of instant coffee contains 85 ~ 200 mg. Therefore, if you drink more than three cans of coke a day, or drink a can of coke, plus a can of oolong tea and a cup of coffee, you will consume more than 200 mg of caffeine, which will easily lead to chronic poisoning if you drink it for a long time.
Tooth corrosion (the protective layer becomes thinner and the teeth become brittle) is caused by acidic substances, while dental caries is caused by eating polysaccharides. Dr. Locke observed that the teeth of 12-year-old teenagers who drank 28 grams of sparkling drinks every day were obviously eroded; Drinking 4 glasses of sparkling drinks every day, the tooth damage of adolescents aged 12 is as high as 25.2%, and that of adolescents aged 14 is as high as 5 1.3%.
Nowadays, all kinds of drinks have become indispensable necessities for people. Different people should choose different drinks according to their needs, so as to relieve summer heat and thirst and supplement nutrient loss. However, experts worry that some people like to drink coke to relieve the heat in summer. Professor Wang Xudong, member of the Chinese People's Political Consultative Conference and director of the Nutrition and Rehabilitation Committee of Jiangsu Traditional Chinese Medicine Association, pointed out that when carbonated drinks represented by cola were first introduced, because of their good taste, the gas produced could take away the heat in the stomach, giving people a feeling of comfort and excitement. With drinking habits, people will have a certain dependence on carbonated drinks. Actually, carbonated drinks have no nutritional value.
According to reports, all kinds of carbonated drinks are high in sugar, and long-term drinking can easily lead to obesity. Coke contains caffeine sodium, similar to caffeine, and also contains preservatives. Whether the content of these ingredients is harmful to human body is hard to say at present, but it is definitely bad for the body and has no nutritional value. Drinking these drinks for a long time will definitely cause problems.
Try to drink less carbonated drinks, especially children, women and the elderly, and it is best not to drink them.
It is harmful for children to drink coke. Cola contains caffeine, and 1 bottle of 340g cola beverage contains 50-80mg caffeine. Someone has done experiments. Adults who take caffeine more than 1 g at a time can cause central nervous system excitement, accelerated breathing, tachycardia, insomnia, dizziness and tinnitus. Even if the dosage of 1 time is less than 1 g, poisoning symptoms such as nausea, vomiting, dizziness, palpitation and precordial pain will occur due to the stimulation of gastric mucosa. Children are more sensitive to caffeine than adults, so don't give them cola drinks.
Young girls beware of osteoporosis. A study shows that soda can accelerate bone loss, especially for girls who love to drink cola, and the probability of fracture is five times that of those who don't drink soda!
Experts pointed out that phosphoric acid in cola may be the cause of easy fracture. Phosphoric acid is harmful to bones because it has adverse effects on calcium metabolism and bones. On the other hand, young girls who drink cola may have insufficient milk intake, which leads to calcium deficiency, so they are prone to fracture.
The newlyweds drink coke carefully. The doctor advised the newlyweds to drink less or no cola drinks. Because most cola drinks contain high content of caffeine, caffeine can easily enter the fetus through the absorption of placenta in the body, which will harm the brain, heart and other organs of the fetus, and also cause fetal malformation or congenital diseases. Therefore, experts suggest that newlyweds and couples who want to have children should not drink cola drinks except smoking. Even after the baby is born, lactating mothers can't drink cola drinks. Because caffeine will also enter the baby indirectly with milk, which is harmful to the baby's health.
Old people shouldn't drink coke. Cola has diuretic effect, which can reduce the absorption of calcium by half. Old people often drink caffeinated drinks, which will aggravate the lack of calcium in the body and easily lead to osteoporosis and fractures.
In addition, drinking too many caffeinated drinks will increase blood lipids and easily aggravate arteriosclerosis. Patients with hyperlipidemia and hypertension drink more alcohol, which will accelerate the deterioration of their condition. For smokers, caffeine can easily mutate some tissues of the body and even lead to cancer cells under the action of nicotine mutagen. In order to avoid the above hazards, we should change the habit of smoking and drinking coke.
