Get in touch with coffee
Caffeine stimulates the central nervous system and muscles, so it can refresh the mind, enhance thinking ability, and restore muscle fatigue. It acts on the cardiovascular system, improves heart function, relaxes blood vessels, and promotes blood circulation. For the gastrointestinal system, it can help digestion and help the breakdown of fats.
Helps to lose weight
I believe many people have heard that drinking black coffee can lose weight. In fact, this is only one of the factors. Caffeine can indeed accelerate the decomposition of fat, but at the same time, it depends on muscle exercise to convert excess fatty acids into heat. If there is no exercise in conjunction with it, the excess fatty acids will flow back down the bloodstream and accumulate fat again. Therefore, after drinking coffee, you need to be active at the same time to achieve the real weight loss effect! Coffee itself has calories, but not many. The main calories are the creamer and sugar you add when you drink coffee.
Antioxidant capacity
In recent years, as long as the food with antioxidant function is popular in the market, the commonly known vegetables and fruits are rich in A, C, and B vitamins, and the tea, which is quite popular in Japan, is regarded as a healthy food. It is because they are rich in antioxidants, which can fight against the damage of free radicals to the human body. A recent research report pointed out that coffee contains four times more antioxidants than tea, which is more effective against cardiovascular diseases. Coffee itself also conforms to the principle of antioxidants, with its color (darkness) and bitter taste. Each coffee contains different antioxidants depending on the brewing method. For example, American coffee contains the least antioxidants, while Espresso contains the most antioxidants. After the coffee is added with creamer, its antioxidant effect will not be affected.
Improve dry eyes
Foreign reports point out that the risk of developing dry eyes in coffee drinkers is significantly lower than that in non-coffee drinkers. This is mainly related to the purine component in coffee (purine-containing eye drops can stimulate the glands to secrete fluid and have a certain protective effect on the eyes). This is of course good news for computer people who love coffee, but it should be noted that coffee itself has a diuretic effect, even if some of its ingredients have a protective effect, it is for people who have already suffered from dry eye, and Anyone taking any medicine containing diuretic ingredients must refrain from taking caffeine-containing beverages to avoid aggravating the loss of body water.
