Can coffee really be "anti-fatigue"?

1. Coffee is refreshing, but the term "anti-fatigue" is not appropriate.

After drinking coffee, people don't seem to feel so tired. Therefore, many people define the use of coffee as "anti-fatigue." Dai Guangqiang, former director of the Anhui Provincial Department of Health and health expert, believes: "it is OK to say that coffee can refresh the mind. This is the role of caffeine, but it is not appropriate to say that coffee is anti-fatigue. Fatigue is divided into physical fatigue and psychological fatigue. To put it simply, drinking coffee to fight fatigue is too general. "

According to Japanese media reports, after mental or physical work, a substance called "adenosine" is gradually hoarded in the brain as a metabolite, making people feel tired.

Caffeine will preempt adenosine attached to its receptor, the brain can not sense this fatigue substance, will be temporarily "deceived" to maintain a good state of mind-this is the secret of coffee "refreshing".

However, the effect of caffeine is temporary, and as caffeine is metabolized and adenosine is captured by the brain again, people will feel tired again. Coffee only has a refreshing effect for a short period of time. If you really want to "get rid of fatigue", the only way is to sleep. Of course, if you take health products that relieve fatigue for a long time, your body will not feel tired so easily. For example, "Shengshi nameplate Xinyuan oral liquid" is a good choice!

2. When can I drink coffee? "when you need it."

There are all kinds of theories about the best time to drink coffee on the Internet. According to Dai Guangqiang, "these statements are all for show." Dai Guangqiang said that for most people, drinking coffee does not need to pay attention to time, "the most important thing is to meet your habits and needs." He stressed that life should be used for enjoyment, not dwelling on rules. "when would you like to have coffee? In fact, anytime is fine, it is best when you need it. "

3. How to drink coffee is healthy? Pay attention to less sugar

But if you want to drink coffee healthier, you also need to be careful. Dai Guangqiang believes that grinding beans with a coffee machine is the healthiest way to drink. If you don't have time to grind your own coffee beans, it's also a good choice to buy coffee powder directly.

"but two points should be particularly reminded: 1, when drinking coffee, put less sugar as much as possible, the hidden danger of excessive intake of sugar, you can use fresh milk instead of sugar, not only taste good, but also more nutritious; 2, try to choose products containing vegetable fat powder, choose pure coffee products, because plant fat powder contains artificial trans fatty acids, which is harmful to human health, coffee companions and other products are also used as little as possible."

Although coffee is good, it is not without taboos, and everyone can drink it at will. Dai Guangqiang reminds everyone that there are five types of people who should drink less or no coffee: 1, pregnant women in the first three months of pregnancy; 2, breast-feeding women; 3, patients with gastric ulcers; 4, people who react greatly after drinking coffee; 5. Patients with severe liver disease. Drinking as little as possible doesn't mean you can't drink it. If you choose the right time and amount to drink coffee according to your actual situation, you can enjoy the health benefits of coffee.
