Coffee common sense: the source of coffee and the benefits of drinking coffee
What's the advantage of drinking coffee?
1. Coffee contains certain nutrients. Nicotinic acid in coffee contains vitamin B, which is higher in roasted coffee beans. And there are free fatty acids, caffeine, tannic acid and so on.
two。 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.
3. 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.
4. 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.
5. Three cups of coffee a day can prevent gallstones. For caffeinated coffee, it stimulates gallbladder contraction and reduces cholesterol, which is prone to gallstones. The latest Harvard University researchers found that men who drank two to three cups of coffee a day were less than 40% likely to get gallstones.
6. Drinking coffee regularly can prevent radiation damage. Radiation damage, especially the radiation of electrical appliances, has become a prominent pollution at present. Indian Barba atomic researchers have come to this conclusion in mouse experiments and say it can be applied to humans.
7. The health care and medical function of coffee. Coffee has the functions of anti-oxidation and heart protection, strengthening muscles and bones, benefiting waist and knees, appetizer, eliminating fat and accumulation, promoting orifice and dehumidification, promoting blood circulation and removing blood stasis, relieving wind and relieving spasm and so on.
8. The influence of coffee on mood. Experiments show that the average person absorbs 300 milligrams of caffeine (about 3 cups of brewed coffee) a day, which has a good effect on a person's alertness and mood.
I believe many people know that drinking coffee can be refreshing, but do not know that it has many benefits. However, everything goes too far, and drinking too much coffee also has some harm. Countries such as the United States and South Korea seem to be with coffee 24 hours a day, but I believe they are also moderate, which is also something we need to pay attention to.
