Drinking black coffee is obviously more beneficial to the human body than very high-sugar drinks such as cola. Coffee is definitely a favorite condiment for office workers. It's great to have a cup of coffee before you start work or when you feel tired and sleepy because of stress. But you should know that everything has two sides, even if the overall properties of an ingredient or beverage tend to be positive, you can't rely too much on it. Please take the right seat. If you are also an experienced coffee maker and want to invigorate yourself with this drink, here are five things you must know.

1 drinking black coffee on an empty stomach will also be "drunk"

It's not just alcoholic drinks, but coffee can also get you drunk. Any doctor or dietitian absolutely does not recommend drinking coffee on an empty stomach because the gastric mucosa absorbs caffeine very quickly on an empty stomach, and as a high concentration of caffeine enters the bloodstream, the heart and nervous system are stimulated, resulting in a series of reactions such as dizziness, palpitations, chest tightness, shortness of breath, night sweats and so on. Therefore, it is best to drink coffee with some small desserts to reduce the absorption of caffeine in the stomach.

2 drinking coffee before exercise can improve the effect of reducing fat

Drinking some coffee before exercise is more likely to boost metabolism and fat burning than exercising without drinking anything, according to a study. This is because when the caffeine in coffee is absorbed into the blood by the gastric mucosa, the body will react to stress, and the concentration of fatty acids in the blood will rise rapidly. the free fat in the body, which is difficult to be well metabolized, will be consumed during exercise.

Drinking some coffee every day can improve the health problems caused by stress

For sedentary office workers, drinking some coffee every day is definitely very beneficial to their health. Caffeine and polyphenols in coffee can increase the concentration of nitrogen oxides, stimulate vasoconstriction and dilation, keep blood vessels elastic, prevent thrombosis, and maintain the health of cardio-cerebrovascular system.

4 Coffee had better be drunk in the morning

After caffeine enters the body, it takes more than 7 hours to be completely metabolized, and the main role of caffeine is to accelerate lymphatic metabolism, stimulate the central nervous system and fight drowsiness, so if the quality of sleep is relatively poor, or if you want to go to bed early at night, it is best to drink coffee in the morning to avoid affecting sleep quality. Of course, if you really like the mellow smell of coffee, you can choose some low-coffee or non-caffeine coffee drinks as a condiment.

5 drinking black coffee around 300ml every day is the healthiest.

Even if there are a lot of benefits, never drink too much coffee. Generally speaking, the amount of coffee you drink every day should not exceed 350ml, and it is best to keep it around 300ml. Drinking this amount of coffee drink can not only prevent health and skin problems caused by excessive caffeine intake, but also supplement sufficient amount of antioxidant polyphenols to combat the invasion of free radicals on the body and skin.
