Polyphenols are thought to have the effect of inhibiting arteriosclerosis, and red wine and cocoa have been widely known to contain polyphenols. But do you know? Coffee also contains polyphenols that can compete with red wine. According to a survey conducted by scholars at the Graduate School of Tea Women's University in Japan, people consume the most polyphenols from coffee during work and after meals during the day.

According to the determination, according to the content of polyphenols equivalent to 100 ml of beverage, red wine varies from 150 mg to 300 mg, with an average content of 230 mg. Coffee contains 200 milligrams of polyphenols per 100 milliliters, while green tea contains about 115 milligrams per 100 milliliters.

The graduate school scholars surveyed the polyphenols intake of these people from a beverage intake survey of 9000 people and a detailed survey of beverage intake of 109 of them. The results showed that 80% of the polyphenols consumed in a day came from drinks and 20% from food. And half of the polyphenols consumed from drinks come from coffee.

Researchers believe that in developed countries, Japan (caused by arteriosclerosis) has the lowest number of patients with myocardial infarction and has the longest life expectancy in the world. The main reason lies in eating and living, and the other is tea, because tea is rich in polyphenols.

If there is a drink that can replace tea and supply the polyphenols needed by the human body, then the first choice is coffee.

The researchers pointed out that although the necessary intake of polyphenols is not clear, based on the benchmark of the previous survey (1000-1500 mg per day), drink 5 cups of coffee or 10 cups of tea a day, which can roughly obtain the necessary intake of polyphenols. It is now known that when you want to calm your mood or adjust your mood, drinking coffee can not only relax your mood, but also be very beneficial to your health, that is, to achieve a good effect both in mind and body. In addition, studies have shown that coffee can prevent cancer and diabetes.

Researchers also believe that previous studies have shown that red wine and polyphenols in cocoa and tea have antioxidant effects. However, drinking wine has alcohol intake problems, and cocoa drinking has calorie intake problems. What is worrying about drinking coffee is the adverse effects of adding milk and sugar, so it is best to drink black coffee without milk and sugar.
