The nutritional value of coffee these people should pay attention to when drinking coffee.

Do not underestimate a small cup of coffee, it can contain a variety of healthy ingredients! Modern medical research points out that coffee beans contain sugars, protein, fat, hydrochloric acid, potassium, crude fiber, water and other nutrients. In addition, coffee also contains caffeine, tannic acid, alkaloids and other beneficial ingredients.

The health effect of coffee on human body

The question of whether coffee is good or bad for the human body has always been concerned by everyone. Some people think that drinking more coffee is good for health, while others think that drinking too much coffee is very harmful to health.

In the "Antioxidant effect" report, coffee is rich in caffeine, caffeic acid, chlorogenic acid and other ingredients, which can effectively resist free radicals that threaten our health. free radicals are the main cause of many diseases (such as cardiomyopathy, arteriosclerosis, stroke, emphysema, Parkinson's disease). Too much free radicals can affect the body's metabolism, destroy cells and then affect organs and tissues.

There is a theory that caffeine can increase the rate at which the body consumes calories. A study found that 100mg of caffeine (about a cup of coffee) can accelerate fat decomposition and increase the body's metabolic rate by 3% to 4%. Drinking in moderation can achieve weight loss. Caffeine can also stimulate the sympathetic nerve and increase gastric juice secretion. If you drink it in the right amount after a meal, it will help digestion. In addition, when it is used as a medicine, it also has the effect of relieving pain (can relieve migraine). According to a new study from the Harvard School of Public Health, people who drink 3 cups of coffee a day are on average 40% less likely to develop gallstones than those who never drink coffee.

The caffeine in coffee can stimulate the central nervous system of the brain, prolong the awake time of the brain, make the mind clear, sharp, and focused, which can improve the efficiency of work and study.

However, for most people who are in coffee, it is to have a relaxed and happy mood and reduce the great pressure of work and study.

These people should be careful when drinking coffee.

At present, there is no clear statement about the harm of coffee to the human body. However, some people should be careful when drinking coffee, especially when they have a physical illness:
