The benefits and disadvantages of drinking coffee-this is a question that most Chinese people will discuss when drinking coffee, but more and more research shows that moderate coffee is entirely a health care product, and the surge in coffee demand caused by the rise of coffee craze is not something to fear for health.

Dr. Fang Xuexian is a member of Professor Wang Fuzhen's research team at Zhejiang University School of Public Health. When sorting out this year's medical and scientific papers, he found that scientists all over the world are particularly interested in coffee research this year.

Is it good to drink coffee every day? What happens when you drink too much coffee? These equivocal questions among ordinary people now have scientific results.

Let's start with the question of whether drinking coffee every day is good.

The answer will please many coffee lovers-drinking coffee every day reduces the risk of death.

This is a study from the National Cancer Institute. The study, which lasted 10 years and looked at blood samples and information about health problems and lifestyle from more than 500,000 British volunteers, found that coffee drinking was associated with a lower risk of all-cause mortality (all-cause mortality), as long as people drank coffee.

The paper was published in the July issue of the Journal of the American Medical Association Internal Medicine. The risk of all-cause death was reduced regardless of whether one drank instant, ground or decaffeinated coffee, the study said. What's more, coffee drinkers had no effect on all-cause mortality regardless of their ability to metabolize caffeine.

Overall, coffee drinkers had a 10 to 15 percent lower risk of death than non-coffee drinkers.

The average age of the volunteers was 57, ranging in age from 38 to 73, and 54 percent were women. Seventy-eight percent of participants drank coffee, 7.3 percent drank less than one cup per day, 20.1 percent drank one cup per day, 31 percent drank two to three cups, 13.4 percent drank four to five cups, 4.1 percent drank six to seven cups, and the remaining 2 percent drank eight or more cups per day.

During the 10-year follow-up, 14225 people died, of which 8294 (58%) died of cancer, 2833 (20%) died of cardiovascular diseases, and 553 (4%) died of respiratory diseases.

"This is a roundup of the effects of coffee." Fang Xuexian said that in nutrition circles, there has been a consensus that moderate coffee consumption is beneficial to overall health.

So how much is "right amount"? "Generally speaking, no more than five cups a day are beneficial to the human body." This was also the amount most people drank. After all, not many people drank coffee as water.

A more accurate figure comes from the U.S. Dietary Guidelines Advisory Committee, which states that drinking no more than five 8-ounce cups of coffee a day is healthy.

"Although studies have shown that instant coffee or ground coffee reduces the risk of death, we recommend drinking less instant coffee." Fang Xuexian said, Instant coffee added too much white granulated sugar, essence, plant fat powder, etc., Cause people intake excessive calories and trans fatty acids,"For coffee lovers, Or choose more ground coffee good."

In addition, a study published in the June issue of the journal PLoS Biology revealed that caffeine can promote regulatory proteins into mitochondria and enhance their function to protect heart muscle cells from damage.

And in the September issue of Nature Communications, there was research suggesting caffeine could help treat diabetes.

In the December issue of the Proceedings of the National Academy of Sciences, researchers found two compounds in coffee that may treat Parkinson's disease.

It seems that 2018 is a year for coffee to gradually move closer to "health products".

"It's very similar to our study of chocolate's benefits to the human body." Fang Xuexian said that coffee is not just caffeine, many of which also contribute to the body."Coffee has a lot of antioxidants, which is why drinking coffee in moderation has more health benefits than disadvantages." It should be noted, however, that these coffee benefits may not apply to women with osteoporosis or pregnancy, as too much caffeine can increase their risk of fractures or miscarriage.
