Coffee is currently the longest-used but most misunderstood beverage. Many new research reports show that in many ways, caffeine is not harmful to human health as thought in the past; on the contrary, some ingredients in coffee have many health effects on the human body, which scientists have gradually discovered.

At present, it is known that the physiological responses of the special ingredients of coffee to the human body are as follows:

Antioxidant effect: coffee is rich in caffeine, caffeic acid, chlorogenic acid and other ingredients, which can effectively resist free radicals that threaten our health. Free radicals are the main cause of many diseases (such as cardiomyopathy, arteriosclerosis, stroke, emphysema, Parkinson's disease). Too much free radicals will affect the metabolism of the body, destroy cells and then affect organs and tissues.

Cardiovascular protection: coffee contains high-content polyphenol compounds, which are powerful antioxidants, which can delay the oxidation of LDL by up to three times, dissolve blood clots and prevent the formation of blood clots; coffee can also enhance vasoconstriction and avoid vascular dilatation and headache. In addition, a small amount of coffee can also enhance myocardial contractility, promote blood circulation and prevent cardiovascular disease.

Coffee is good for the skin. Coffee can promote metabolic function, activate digestive organs, and has a great effect on constipation. Taking a bath with coffee powder is a kind of thermotherapy, which has the effect of losing weight.

Coffee has the function of relieving alcohol. Drinking coffee after drinking alcohol will quickly oxidize the acetaldehyde converted from alcohol, decompose it into water and carbon dioxide and discharge it out of the body.

Coffee can relieve fatigue. In order to eliminate fatigue, we must supplement nutrition, rest and sleep, and promote metabolic functions, and coffee has these functions.

The current recommendation for healthy people is to consume 400 milligrams of caffeine a day. This is about four 8-ounce cups of brewed coffee.
