Coffee and prevention of radiation injury

Indian scientists have found that coffee protects experimental mice from radiation and may have the same effect on humans. Researchers at the Barba Atomic Research Center in India found that 70 per cent of caffeine-injected mice survived 25 days after receiving generally lethal doses of radiation, while all of the uninjected mice died. Caibili George, who led the study, said the findings may also apply to humans. "the study does show that coffee may help prevent radiation damage," he said.

Coffee and prevention of gallstones

Delicious coffee is a refreshing drink, and new research has found that drinking a few cups of coffee a day can prevent gallstones. According to the latest issue of the Journal of the American Medical Association, researchers at Harvard University have found that men who drink two or three cups of coffee a day are 40% less likely to get gallstones than those who do not drink coffee, and if they drink more than four cups of coffee a day, the risk of gallstones is even reduced to 45%. However, decaffeinated coffee does not have this effect. Only caffeinated coffee can stimulate gallbladder contraction and reduce cholesterol, which is easy to form gallstones in bile. Other drinks such as tea and cola, which also contain caffeine, cannot achieve the same effect because their caffeine content is lower than that of coffee.

Antioxidant and cardioprotective function of coffee

In addition to being refreshing, coffee contains polyphenols that not only have antioxidant effects, but also protect cardiovascular functions. At the recent symposium on food chemistry at the annual meeting of the American Chemical Society, there is new scientific evidence that coffee contains powerful antioxidants that protect the heart and blood vessels. The study, led by Professor J. A. Vinson of University of Scranton University in Pennsylvania, found that coffee contains high levels of polyphenols (Polyphenols), sometimes called flavonoids (flavonids), which are powerful antioxidants that fight oxidation and blood clotting.

The influence of coffee on people's mood

Recently, Professor A. P. Smith of the University of Bristol (University of Bristol) in the United Kingdom published his ten-year talk about the imagination of coffee on the brain, especially its effect on discrimination and mood. Measure their discrimination and alertness for 30 minutes before and after drinking coffee. Smith found that after drinking a cup of coffee, they become more alert and more focused. Professor Smith said that coffee can really refresh you, especially if you don't get enough sleep, if a cold makes you sleep badly, or insomnia, and you have to concentrate on your work or exams during the day, then drinking a cup of coffee will certainly boost your alertness and tide you over. And coffee will stay in the body for three to five hours, so coffee has a long-term refreshing effect. Further experiments have found that the average person can absorb 300 milligrams of caffeine (about three cups of brewed coffee) a day and have a positive imagination for a person's alertness and mood. However, more than 400 milligrams (four cups) of caffeine will bring side effects, such as mood deterioration, irritability, aggression and causing trouble. If you only want to eat coffee polyphenols as antioxidants, then all you have to do is drink decaf coffee.

Studies have found that coffee drinkers are less likely to develop Parkinson's disease

Drinking more coffee may help reduce the risk of Parkinson's disease, according to a new study in the United States.

Scientists at the Veterans Management Medical Center in Honolulu, Hawaii found that people who did not drink coffee had a five times higher risk of developing Parkinson's disease than those who drank more than five cups of coffee a day. The researchers followed more than 8000 men for 30 years, and their findings were published in the Journal of the American Medical Association.

Parkinson's disease is a kind of senile disease with neurological lesions. Typical symptoms include limb tremor, stiffness, decreased autonomic activity and so on. Researchers do not know why drinking coffee may reduce the risk of Parkinson's disease. But they speculate that the caffeine in coffee may prevent damage to the nerve cells that cause Parkinson's disease.

Scientists point out that the results they have so far are only preliminary and need to be confirmed by further research. They stressed that it is too early to recommend coffee as a treatment for Parkinson's disease.
