And close contact with coffee
Caffeine stimulate the central nervous system and muscle due to the role, so you can pull themselves together to enhance the ability to think, to restore muscle fatigue.

So after a cup of coffee need to actively move, can play a real slimming effect! Coffee itself has calories, but not much, mainly the heat is on when you join the coffee creamer and sugar.
Antioxidant capacity
In recent years, as long as the food with antioxidant functions have become very popular in the market, generally well-known fruits and vegetables rich in A, C, B vitamins in the food, and very popular tea in Japan, the reason being as a healthy food, is for their rich antioxidant substances can harm the human body against free radicals. Recent studies have shown that coffee contains more antioxidants than tea 4 times more against cardiovascular disease, and the coffee itself is also in line with the principle of antioxidants, color (deep) also have a bitter taste. Each coffee contains antioxidants also brewing because of differences in the way, such as the quality of American coffee with a minimum of antioxidants, while the Espresso antioxidant contained in the most. After the addition of cream in coffee, it will not affect its antioxidant effect.
Improve dry eyes
Foreign reports that: those who suffer from dry eye coffee chance, obviously lower than those who do not drink coffee. This is mainly and coffee in the purine component (Han Piaoling of eye drops, can stimulate the glands secrete fluid, the role of the eyes with some protection). For computer users who like to drink coffee, which of course is good news, but it should be noted that the diuretic effect of coffee itself, even if some of the components has a protective effect, but for those who already suffer from dry eye, and taking any pharmaceutical composition containing the urine of people, must be prohibited taking caffeinated beverages, so as not to exacerbate the loss of body water.

Caffeine helps increase awareness, sensitivity, memory and concentration. But drinking more than usual than you are used to the amount of coffee drinking, it will have a similar eating the same dose of stimulants, can cause nervousness. For anxiety disorders tend to people, caffeine causes the palms sweating, heart palpitations, tinnitus, the symptoms worsen.
Increased blood pressure
Caffeine because of its analgesic effect has often simple analgesics and other synthetic compound, but the long-term large doses, if you have high blood pressure itself, the use of large amounts of caffeine will only make your situation worse. Because caffeine can make blood pressure alone, when coupled with emotional stress, it will have dangerous effects of multiplying, therefore, the risk of hypertension, particularly among the working pressure should be avoided when drinking caffeinated beverages . There are some perennial coffee habits, the effect of caffeine that they have been immune, however, is not the case, a study, a cup of coffee, the blood pressure may take up to 12 hours.

Caffeine itself has a good diuretic effect, if long-term and a lot of coffee, easily lead to bone loss, preservation of bone mass have an adverse effect, for women, may increase the threat of osteoporosis. But the premise is that normal food was a dearth of adequate calcium intake, or do not always move people, with women after menopause, estrogen lack of calcium caused by the loss of these plus a lot more than caffeine , it may pose a threat to bone. If a reasonable amount in accordance to enjoy, you can still do not unworthy of.
These people drink coffee Shen
Liver disease
Caffeine, caffeine in the body will be extended Xie time. The normal metabolism of caffeine in adults 2 hours, but patients with liver disease or liver dysfunction, the metabolism of caffeine may be 4-5 hours, so patients with liver disease in a cup of coffee would have to be careful, it is best not to After drinking in the evening, to avoid affecting the metabolism of long sleep, and not more than 1 cup a day is best.
Digestive system disease
I believe people often have a stomachache stomach experience is that doctors will asked, do not eat spicy food, including: wine, pepper, coffee, tea, carbonated drinks.
One reason why the inclusion of coffee, which is due to the tannins will stimulate gastric acid secretion, if it is acute digestive disease patients must be avoided. Recovered, if the occasional drink coffee, it is best used in the meal to avoid fasting coffee.
