Will coffee be hot?

That kind of appropriate bitterness, rich and mellow taste, makes people fascinated. This is the charm of coffee. Especially when it turns cold, a cup of hot and fragrant coffee will naturally bring warmth to my heart. Whether you are tired from walking, finding a place to sit down and rest, finding a good place to chat with friends, or finding a good way to refresh yourself in the office, people can't help but want to get close to coffee. However, how to drink coffee is healthy? Who is not suitable for drinking coffee? Close contact with coffee caffeine can stimulate the central nervous system and muscles, so it can refresh the mind, enhance thinking ability and restore muscle fatigue. Acting on the cardiovascular system can improve heart function, relax blood vessels and promote blood circulation. For the gastrointestinal system, it can help digestion and help the decomposition of fat. I believe many people have heard that drinking black coffee can lose weight. In fact, this is only one of the factors. Caffeine can really accelerate the decomposition of fat, but at the same time, it needs to rely on muscle movement to convert excess fatty acids into heat energy for consumption. If there is no coordinated exercise, excess fatty acids will flow back along the blood stream and accumulate fat again. Therefore, after drinking coffee, you need to exercise actively at the same time in order to have a real weight loss effect! Coffee itself has calories, but not much. The main calories are the creamer and sugar you add when you drink coffee. Antioxidant capacity In recent years, all foods with antioxidant function have become popular in the market. Foods rich in vitamins A, C and B in vegetables and fruits, as well as tea, which is quite popular in Japan, are regarded as healthy foods because they are rich in antioxidants and can resist the harm of free radicals to the human body. A few days ago, a research report pointed out that the content of antioxidants in coffee is four times that of tea, and it has stronger resistance to cardiovascular diseases. Moreover, coffee itself conforms to the principle of antioxidants, with darker color and bitter taste. Each coffee contains different antioxidants because of different brewing methods. For example, American coffee contains the least antioxidants, while espresso contains the most antioxidants. After adding creamer to coffee, its antioxidant effect will not be affected. It has been reported abroad that people who drink coffee are significantly less likely to suffer from dry eye than those who don't drink coffee. This is mainly related to the purine component in coffee (eye drops containing purine can stimulate glands to secrete liquid, which has a certain protective effect on eyes). This is of course good news for computer people who love to drink coffee, but it should be noted that coffee itself has diuretic effect, even if some of its ingredients have protective effect, people who have already suffered from dry eye and those who have taken any drugs containing diuretic ingredients must be forbidden to take caffeinated drinks so as not to aggravate the loss of water in their bodies. So far, no research results show that caffeine in coffee is harmful to beauty. On the contrary, moderate caffeine can accelerate metabolism, promote digestion, improve constipation, improve rough skin, and relieve headache caused by poor sleep all night, or pain caused by vasoconstriction on one side of the temple. These non-organic factors can be alleviated by coffee, but you must drink it in the morning or at noon (note: it is forbidden from afternoon to night).
