Coffee can drink healthily when drunk scientifically.

Drinking coffee is best after breakfast and lunch, because it can promote gastrointestinal peristalsis, help digestion, can break down high-calorie, high-fat foods, and will not cause irritation to the stomach like drinking coffee on an empty stomach. It's best not to drink coffee after dinner, for fear it will affect your sleep. If you want to stay up all night by drinking coffee, you may drink too much without knowing it, which is bad for your health.

The amount of coffee

Coffee is good for the body, but you can't drink more than 2 cups a day. For people who are prone to tension and anxiety, drinking too much may be harmful.

Help to lose weight

I believe many people have heard that drinking black coffee can help you 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 the excess fatty acids into heat energy. Without matching exercise, the excess fatty acids flow back down the bloodstream and re-accumulate fat. So after drinking coffee, you need to be active at the same time in order to play a real weight loss effect! Coffee itself has calories, but not much. The main calories are the cream and sugar you add when you drink coffee.

Antioxidant capacity

In recent years, as long as foods with antioxidant functions are popular in the market, well-known vegetables and fruits that are rich in A, C, B vitamins, as well as tea, which is quite popular in Japan, are regarded as healthy foods because they are rich in antioxidants, which can resist the harm of free radicals to the human body. Coffee contains four times more antioxidants than tea and is more resistant to cardiovascular disease, and coffee itself conforms to the principle of antioxidants and has a bitter (dark) color. Each coffee contains different antioxidants depending on the way it is brewed. For example, American coffee contains the least antioxidants, while Espresso contains the most antioxidants. After the addition of cream, coffee will not affect its antioxidant effect.

Improve dryness of the eyes

Coffee drinkers are significantly less likely to develop xerophthalmia than non-coffee drinkers. This is mainly related to the purine ingredients in coffee (purine-containing eye drops that stimulate glands to secrete fluid and have some protective effect on the eyes). This is of course good news for computer users 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, but for people who already suffer from xerophthalmia, and those who take any drugs containing diuretics, caffeinated beverages must be prohibited so as not to aggravate the loss of water in the body.

It relieves pain.

Headache caused by a good night's sleep, or pain caused by vasoconstriction on the temple side, the pain caused by these non-organic factors can be relieved with coffee, but it must be drunk in the morning or noon (note: prohibited from afternoon to night).

Aid digestion

Everyone knows that there is caffeine in the coffee. It is well known that caffeine can stimulate nerves and muscles, invigorate the spirit and fight fatigue. In fact, coffee can help digestion for the stomach and intestines.
