The role of coffee

What is the charm of coffee that attracts people? The appropriate sour and bitter taste, the fragrant aroma, and the magical effect of caffeine... Alcohol or tobacco can make people feel intoxicated and stimulated, and similarly, caffeine can make people feel excited. Caffeine can stimulate the central nervous system or muscles, which can restore muscle fatigue, improve work efficiency, have a sobering effect, and can make the mind active and sensitive. In addition, by stimulating the sympathetic nerves, it can suppress asthma caused by the excitement of the parasympathetic nerves.

Coffee also helps digestion, especially when you have eaten meat, gastric juice secretion is high, which promotes digestion and prevents gastroptosis. Since caffeine can break down fat, many people will want to drink a cup of coffee after eating high-energy food. However, studies have shown that the digestive effect of coffee can cause false hunger and may lead to an increase in food intake!

1. Coffee contains certain nutrients. The nicotinic acid in coffee contains vitamin B, and the content is higher in roasted coffee beans. It also contains free fatty acids, caffeine, tannic acid, etc.

2. Coffee is good for the skin. Coffee can promote metabolism, activate digestive organs, and has a great effect on constipation. Taking a bath with coffee powder is a warm therapy that helps lose weight. Drinking a cup of coffee after a meal can also help digestion.

3. Coffee can help you sober up. Drinking coffee after drinking alcohol will cause the acetaldehyde converted from alcohol to be rapidly oxidized, decomposed into water and carbon dioxide and excreted from the body.

4. Coffee can eliminate fatigue. To eliminate fatigue, you must supplement nutrition, rest and sleep, and promote metabolic function, and coffee has these functions.

5. Three cups of coffee a day can prevent gallstones. Caffeinated coffee can stimulate the contraction of the gallbladder and reduce the cholesterol in the bile that is prone to forming gallstones. The latest research from Harvard University in the United States found that men who drink two to three cups of coffee a day have a 40% lower chance of getting gallstones.

6. Drinking coffee regularly can prevent radiation damage. Radiation damage, especially radiation from electrical appliances, has become a prominent form of pollution. Indian researchers at the Bhabha Atomic Energy Institute came to this conclusion in a mouse experiment and said it can be applied to humans.

7. Coffee's health and medical functions: Coffee has the functions of anti-oxidation, protecting the heart, strengthening the tendons and bones, benefiting the waist and knees, stimulating appetite, eliminating fat and stagnation, benefiting the orifices and removing dampness, promoting blood circulation and removing blood stasis, and calming wind and stopping spasms.

8. The influence of coffee on mood. Experiments show that if an average person absorbs 300 mg (about 3 cups of brewed coffee) of caffeine a day, it will have a good effect on a person's alertness and mood.

Just like the intoxication and stimulation of alcohol and cigarettes, caffeine has a stimulant effect. Caffeine can stimulate the central nervous system and muscles, so it can relieve muscle fatigue, control sleep, and stimulate the mind.

On the one hand, it improves heart function, dilates blood vessels, promotes blood circulation, calms headaches and makes people feel refreshed.

On the other hand, it can stimulate the sympathetic nerves and control the paroxysmal dyspnea caused by parasympathetic nerve excitement.

Coffee also helps digestion, especially when you eat too much meat, it can increase gastric juice secretion, promote digestion, and reduce the burden on the stomach. Because caffeine has the effect of breaking down fat, you must drink some coffee after eating high-calorie food.

Coffee can also eliminate the odor of garlic. Drinking some coffee after eating garlicky dishes is essential. Coffee also has a deodorizing effect. When using a drip coffee pot, you can dry the coffee grounds in a container and place it in the corner of the refrigerator for deodorization. It can also be placed in the shoe cabinet as a deodorant. If you place it under a cigarette can, it can also remove the odor of cigarettes.

In addition, coffee can also be used as a seasoning for cooking. For example, when cooking ribs, put some instant coffee in the soup, and when roasting meat, dip some coffee on the meat, the roasted meat will taste especially fragrant.

Is the caffeine in coffee harmful to the human body? Many people may have doubts. However, the amount of caffeine in 2-3 cups of coffee is absolutely fine. Moreover, the right amount of caffeine has therapeutic effects.
