Coffee pros and cons debate the pros and cons of drinking coffee

"come on, have a cup of coffee!" For modern people, this sentence has become a familiar social language. From the young to the old, a cup of coffee has become an indispensable part of many people's lives.

The pros and cons of coffee are debated endlessly

Although people have been drinking coffee for more than 1500 years, the word "coffee" is rarely associated with "health". While enjoying coffee, many people can't help worrying about whether they will be addicted to it, will it cause insomnia, will it lead to osteoporosis, and will it endanger cardiovascular health. In spite of this, people never stop chasing coffee.

According to statistics, more than 100 million Americans drink coffee in the morning, an average of 1.64 cups a day, and more and more children drink coffee. Coffee is drunk in every corner of the world, but it has been debated whether it is harmful or beneficial. It was not until the last decade that more and more nutrition experts intervened to make people see the bright side.

The research results are very optimistic.

So far, more than 19000 coffee studies have been carried out in the United States alone, involving a wide range of contents. "We are willing to study coffee only because people drink too much." "and we have reason to believe that there must be something magical about the drinks that people have eliminated over thousands of years," said Dr. Gilbert, a former director of the coffee research institute at Vanderbilt University. "

Now, research on coffee is published almost every day. In the first and middle of August alone, ABC, the Internet Doctor of Medicine, MSNBC and other media reported more than 10 new studies on coffee. Among them, a study by Scranton University in Pennsylvania found that American adults consume the most antioxidants from coffee, at 1299 mg a day, followed by tea at 294mg, and other foods at less than 100mg. Researchers at the Harvard School of Public Health have found that drinking coffee can prevent type 2 diabetes because it stimulates insulin secretion and lowers blood sugar levels. Experts also found that people who drank one or two cups of coffee a day had a half less risk of liver cirrhosis and liver cancer than those who did not drink it.

A variety of research results have been published, but so far, the more definite effects of coffee include: 1. Antioxidants. Caffeine, caffeic acid and other ingredients can effectively fight against free radicals that cause diseases such as aging or tumors. two。 Protect the cardiovascular system. Coffee contains high levels of polyphenols, which can prevent thrombosis. 3. Refreshing and refreshing. The caffeine in coffee stimulates the central nervous system, prolongs the waking time of the brain, and makes the mind clear and sharp. 4. Control your weight. Caffeine can accelerate fat decomposition and have the effect of weight loss. 5. Improve constipation. Coffee can stimulate gastrointestinal peristalsis and produce laxative effect. Other benefits that need to be further studied include promoting digestion, relieving pain, preventing gallstones and preventing memory loss.
