Is it healthy to drink coffee? Drinking coffee to fight cancer also causes cancer.

Many people like to drink coffee, but many nutritionists have put forward different views. some people think that coffee can fight cancer, but it is said that coffee hurts the stomach, so is drinking coffee good or bad? Is coffee really what people say it is? The editor will explain it in detail below.

Coffee is the extract of coffee beans, which contains no less than hundreds of ingredients. Among them, caffeine is undoubtedly the most important. Although there is decaffeinated coffee, for most coffee lovers, it is not "real" coffee. Caffeine can stimulate nerve excitement, so the role of coffee is first of all "refreshing". In particular, caffeine plus glucose can promote each other to make the pick-me-up effect better. Caffeine is also added to many sports drinks as a legal "stimulant".

Whether caffeine has other "health functions" has also attracted a lot of attention from scientists. There are a lot of such studies, and on the whole, some studies have shown that they may be effective. For example, some old people will get dizzy because of low blood pressure after a meal. If you drink a drink containing caffeine, it may relieve this symptom. The so-called "caffeinated drink", in addition to coffee, tea or cocoa can also be. Parkinson's disease is a common geriatric disease, and studies have shown that caffeine is effective in reducing the risk of Parkinson's disease. Men drink three to four cups a day to achieve the maximum effect, while one or two cups a day also have a significant effect. Women, on the other hand, have little to do with consumption and achieve maximum results with one to three cups a day.

Interestingly, however, this effect does not exist for smokers. In addition, caffeine can also help reduce gallstones. 400 milligrams of caffeine (about three or four cups of coffee) a day can show an effect. Interestingly, the relationship between the effect on type 2 diabetes and intake has much to do with race. Among people in Europe and the United States, drinking six cups of coffee a day can reduce the risk by more than 50% for men and about 30% for women. Among Japanese, drinking three drinks a day can be reduced by 42%.

Besides caffeine, coffee also contains many other "active ingredients", such as antioxidants. Especially roasted coffee beans, the content of antioxidants will increase. Antioxidants are good for cardiovascular health, but coffee also contains "harmful substances", such as diterpenes, which increase the risk of cardiovascular disease. In this case of "fighting between the left and the right", it depends on which side takes the lead. Fortunately, diterpenes can be filtered out by coffee paper, so unfiltered coffee or metal mesh filtering is not recommended. The "anti-cancer" effect has a similar situation, with studies showing that three cups of coffee a day may reduce the risk of rectal cancer. However, baking not only increases the content of antioxidants, but also produces acrylamide, and high doses of acrylamide show carcinogenicity in animal experiments.
