Like Coca-Cola, Pepsi-Cola and Sprite, they are not only bad for human body, but also harmful!
Coke is mainly composed of syrup and carbon dioxide gas. No nutrition for the body.
Regular drinking of cola will not only lead to obesity, but also lead to dental caries, osteoporosis and heart disease. It is also a potential risk factor for modern diseases such as diabetes.
Not to mention the harm of pigments, spices, caramel and other additives contained in cola to human body, only caffeine is a substance harmful to health. Caffeine is a drug that can excite the central nervous system, heart and blood vessels and damage memory.
For children, caffeine is irritating, which can stimulate gastric peristalsis and gastric acid secretion, causing intestinal spasm. Children who often drink coffee are prone to unexplained abdominal pain, and long-term excessive intake of caffeine can lead to chronic gastritis. Caffeine can dilate capillaries in gastrointestinal wall, stimulate renal function, increase renal water flow, lead to polyuria in children, increase calcium excretion, and affect children's bone development. At the same time, caffeine can also destroy vitamin B 1 in children, causing vitamin B 1 deficiency.
A can of 355 ml cola contains 65 mg of caffeine, and a can of 350 ml oolong tea contains 80- 120 g of caffeine.
A cup of instant coffee contains 85-200mg of caffeine. Normal people should not consume more than 200 mg of caffeine every day, otherwise they may be chronically poisoned. Children should stay away from coffee and drink caffeinated drinks as little as possible.
The pH value is between 1 and 14 degrees, and 7 degrees is neutral. If the acidity of the beverage is lower than 5.5pH, the enamel can be dissolved.
And some chemicals in cola, such as sodium, can raise blood pressure. Experts warn that high blood pressure will increase people's risk of heart disease, stroke and kidney disease, which cannot be ignored.
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. These ingredients are not good for health and have no nutritional value. Drinking these drinks for a long time will definitely cause problems.
