Why coffee can refresh? Coffee Health

Coffee may keep you awake at night, or it may raise your blood pressure.

But Professor Martin, director of Vanderbilt University's Coffee Institute, said coffee contains hundreds of healthful ingredients that can fight liver damage, various cancers, asthma, heart disease and Parkinson's disease.

2-4 cups per day is appropriate

He noted that drinking 2-4 cups of coffee a day is beneficial. People who do not drink coffee are more likely to suffer from these diseases than coffee drinkers. Nearly 20 years of research have confirmed that caffeine is an active ingredient in coffee that activates the central nervous system and can be used to create long-lasting painkillers that fight drowsiness, colds, asthma and edema. Side effects are addiction, insomnia, stress and elevated blood pressure.

Coffee contains anti-dementia substances

Coffee contains anti-dementia substances that reduce the effects of harmful substances on the body and help prevent some diseases, research shows. When oxygen mixes with other chemicals in the body, it forms harmful substances that blindly destroy cells and body tissues, which is the cause of heart disease, vascular disease, tumors, immune decline and neurasthenia, scientists say. Coffee contains four times more anti-dementia substances than tea, according to the coffee institute. Nutrition plays a major role in strengthening the body's disease prevention mechanisms. Substances that can fight dementia include vitamin E, vitamin C, carotene in soybeans, red wine, certain seasonings, fruits, onions and olives. Roasted coffee beans are more resistant to dementia, and decaffeinated coffee does not weaken or destroy the substance. At the same time, experts point out that a cup of coffee after getting up in the morning can refresh your mind, and a sip of coffee during the day can refresh you.

Boiled water can be used simultaneously.

The coffee can be a little stronger at this point. And after dinner or evening coffee to slightly lighter is appropriate. Coffee is recognized as a healthy drink, but drinking coffee should be controlled for a certain time, to be timely and moderate. Coffee or tea is not suitable for drinking with meals and should be drunk after meals. When drinking coffee, you should drink some plain water, whether it is hot or cold. This is to remove the odor of the mouth, so as to better taste; second, because coffee has diuretic function, drink more white water, can improve the amount of urine, protect kidney function, and do not worry about drinking coffee will "get angry".
