Foreign reports point out that people who drink coffee are much less likely to suffer from dry eye than those who don't drink coffee.

No more than a few cups of coffee a day.

I want something with actual data!

Recently, Professor A.P. Smith of the University of Bristol, England, published his ten-year report, studying the influence of coffee on brain nerves, especially on discrimination and mood. Their discrimination and alertness were measured 30 minutes before and after drinking coffee. Smith found that after drinking a cup of coffee, they became more alert and more focused. Professor Smith said that coffee can really refresh you, especially when you don't get enough sleep, and if you have to concentrate on work or exams during the day, drinking a cup of coffee will definitely improve your alertness and help you tide over the difficulties, and coffee will stay in your body for three to five hours, so coffee will keep you awake for a long time.

Further experiments also found that the average person can absorb 300 milligrams (about three cups of brewed coffee) of caffeine every day, which will have a positive impact on a person's alertness and mood.

A cup of coffee every day may lead to obesity. Drinking coffee properly can reduce weight, but if you drink coffee every day, you will not lose weight, but you will get fatter and fatter.

The method of not getting fat after drinking coffee:

1, reduce the composition

Although adding cream flowers to coffee will make the taste more fragrant, in fact, these cream flowers are difficult to decompose after drinking, but they will be converted into body fat, which is difficult to lose easily. Nuts, chocolate syrup and buttered flowers have the same fattening effect as ingredients, so we must put them as little as possible or not at all.

Step 2 refuse to buy a large cup

The price of a large cup is similar to that of a small cup, and it will be replaced by a large cup because of its higher cost performance, but this is equivalent to intaking too much sugar invisibly.

You will be healthier yourself.

Buying coffee outside is the same as eating out. Merchants will add a lot of additives such as sweeteners to make coffee taste better. In fact, household honey and sugar can also make the same taste, and the calories will be less.

4. Reduce the frequency of drinking coffee

Whether you buy coffee according to the above standards or not, the most fundamental way is to reduce the frequency of drinking coffee from one cup a day to two or three cups a week. If you feel thirsty or sleepy and want to boost your spirits, you might as well drink some pure water or lemonade, which is both healthy and fat-reducing.

It is good for women to drink several cups of coffee every day.

Nowadays, coffee has become a fashionable drink, and there are more and more cafes. Young people like to go to cafes for parties, and coffee has become a must-have drink for many families.
