Count the pros and cons of drinking coffee

What are the advantages and disadvantages of drinking coffee? Modern people like to drink coffee more and more, not only because it is refreshing, but also because it is unique and mellow. But there are always two different voices in the outside world of coffee. Some people think that coffee is a good thing, while others think that drinking more coffee is useless. In fact, coffee has both advantages and disadvantages. Let's take a look at the advantages and disadvantages of coffee.

1. Help lose weight

I believe many people have heard that drinking black coffee can help you lose weight. Indeed, caffeine can speed up fat decomposition. But drinking coffee to lose weight must be combined with exercise, so that the excess fatty acids can be converted into heat energy consumption, otherwise excess fatty acids will flow back along the blood and accumulate into fat.

It has been reported that coffee contains four times more antioxidants than tea and can fight cardiovascular disease. And even if cream is added to coffee, its antioxidant effect will not be affected.

3. Improve the dryness of eyes

There are reports abroad that coffee drinkers are significantly less likely to suffer from xerophthalmia than non-coffee drinkers. This is mainly due to the purine ingredient in coffee. Many eye drops contain purines, which can stimulate glands to secrete fluid and have a certain protective effect on the eyes. However, it should be noted that coffee itself has a diuretic effect, and people who already suffer from dry eyes must prohibit drinking caffeinated beverages so as not to aggravate the loss of water in the body.

4. Relieving pain

If you don't sleep well at night, or a headache caused by vasoconstriction on the temple side, coffee can be used to relieve discomfort. But it must be drunk in the morning or at noon. If you drink it from afternoon to night, it may affect your sleep that night.
