Can children drink coffee?

Coffee is a common thing in people's daily life. Many times, some people drink coffee to achieve the effect of refreshing their minds. But anyone who knows a little about coffee knows that coffee contains something that can boost people's mood. Many times these things have a great impact on people's physical health. So for children with weak immunity and physical condition, can they drink coffee in their daily life?

1. People who want to lose weight should not drink too much coffee. Common coffee companions contain more milk, sugar and fat. Coffee itself may stimulate the secretion of gastric juice and promote food digestion and absorption. It not only cannot slim the waist, but also makes people fat.

2. Children should not drink coffee. Caffeine can excite children's central nervous system, interfere with their memory, and cause ADHD in children;

3. People who are prone to hypertension. Because of its analgesic effect, caffeine is often combined with other simple analgesics. However, long-term and large-scale use will only make your condition worse if you already have high blood pressure.

4. Menopausal women. Caffeine itself has a good diuretic effect. If you drink coffee for a long time and in large quantities, it can easily cause bone loss and have an adverse effect on bone mass preservation. For women, it may increase the threat of osteoporosis.

Benefits of drinking coffee

Coffee is not only a refreshing drink, but also can prevent gallstones.

Researchers at Harvard University in the United States found that people who drink two to three cups of coffee a day have a 40% lower risk of developing gallstones than those who do not drink coffee. For people who drink more than 4 cups of coffee a day, the risk of developing gallstones will be reduced to 45%. However, decaffeinated coffee does not have this effect. Caffeine can stimulate gallbladder contraction and reduce the cholesterol in bile that is prone to form gallstones. However, beverages such as tea and cola that also contain caffeine cannot achieve this effect because the caffeine content is lower than that of coffee.

Radiation protection

At present, the radiation produced by radioactivity has become a major enemy that endangers people's health. Especially the radiation from household appliances, such as computers, televisions, microwaves and so on. Recent research has found that coffee can protect mice from harmful radiation, a finding that may also apply to humans. Researchers at India's Bhabha Atomic Research Center found that 70% of experimental mice injected with caffeine were still alive 25 days after receiving a high dose of radiation that would normally be lethal, while all the mice that did not receive the injection died. Giorgio Cacciapielli, who led the study, said the findings may also apply to humans. "It does suggest that coffee may help protect against radiation damage," he said.

Protect cardiovascular system

The polyphenols contained in coffee not only have antioxidant effects, but also have the function of protecting the cardiovascular system. Recently, at a symposium on food chemistry at the annual meeting of the American Chemical Society, new scientific evidence was presented to prove that coffee contains powerful antioxidants that can protect the heart and blood vessels. These polyphenols, also known as flavonoids, have strong antioxidant properties.

Prevent gout

Increased uric acid in the blood is the main cause of gout, and increasing daily coffee intake can significantly reduce uric acid levels in the blood. People who love drinking coffee, especially those who drink more than two cups of coffee a day, have significantly lower uric acid levels in their blood, thereby greatly reducing the incidence of gout.
