Coffee contains caffeine, and whether it reacts to caffeine varies from person to person. For example, some people are allergic to pollen, while others are not suitable for eating seafood. And these two situations, for most people like you and me, will not have any impact. As for how much coffee to drink every day, in some coffee-consuming countries, people consume about 250-600 milligrams of caffeine every day on average. After repeated scientific research and analysis, this dose has no side effects on human body. So you can drink 4- 10 cups of instant coffee every day.
What effect does drinking coffee have on health?
Your main concern is whether the caffeine contained in coffee has an impact on health. In fact, caffeine is a mild stimulant in coffee, which can improve human sensitivity and attention, accelerate human metabolism, and improve human mental state and physical quality. At present, caffeine has been found in about 60 kinds of plants, of which tea and coffee are the most well known. In some coffee-consuming countries, people consume about 250-600 milligrams of caffeine every day on average. After repeated scientific research and analysis, this dose has no side effects on human body.
You can't drink too much coffee every day.
People often ask, how much coffee is excessive? In some coffee-consuming countries, people consume about 250 to 600 milligrams of caffeine every day on average. After repeated scientific research and analysis, this dose has no side effects on human body. Because the caffeine content in a cup of coffee (150ml) is generally:
-Ground coffee: about 80-90 ml.
—— Instant coffee: about 60ml.
In some coffee-consuming countries, people consume about 250-600 milligrams of caffeine every day on average. After repeated scientific research and analysis, this dose has no side effects on human body. The caffeine content of a cup of instant coffee (about 150 ml) is generally about 60 mg, so drinking 4- 10 cups of instant coffee every day will not be excessive.
The efficacy of coffee
Alcohol or tobacco can make people feel intoxicated and stimulated, and caffeine can also make people feel excited. Caffeine can stimulate the central nervous system or muscles, restore muscles or fatigue, improve work efficiency, have a sober effect, and make the brain more active and sensitive.
On the other hand, it can also improve heart function, dilate blood vessels, have good blood circulation, have a calm headache and feel comfortable. And asthma can inhibit the excitement of parasympathetic nerve by stimulating sympathetic nerve. Other coffee also helps digestion, especially when eating too much meat, which can promote digestion and prevent gastroptosis. Because caffeine can break down fat, westerners must want to drink coffee after eating energy-enhancing food. Caffeine can not eliminate garlic flavor, but also contains betel nut, so coffee is an indispensable drink after taste compensation cooking.
In addition, coffee also has a deodorizing effect. Residues brewed with ground coffee can be dried in containers and used as deodorizers in refrigerators or shoe boxes. Sprinkling on the ashtray can also eliminate the smell of tobacco. And coffee can also be used to hide the taste. For example, instant coffee can be turned into a sweet and delicious meat dish if it is melted with boiling water and its taste is stained with meat.
Coffee contains a lot of caffeine, will it affect your health? Maybe some people will have such concerns. However, the amount of two or three cups of coffee is no problem. On the contrary, drinking coffee in moderation is effective for the body. Understand coffee correctly, so that everyone can drink coffee happily and enjoy coffee time!
Coffee and the influence of people's mood
Recently, Professor A.P.Smith of the University of Bristol in the United Kingdom published his ten-year report on the influence of coffee on brain nerves, especially the influence of coffee on discrimination. 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. If you have a cold and have to concentrate on going to work or coping with exams during the day, drinking a cup of coffee will definitely promote your alertness and help you tide over the difficulties. Coffee will stay in the body for 2 to 5 hours, so coffee has a long-term refreshing effect. Further experiments show that the average person can absorb 300 mg (about three cups of brewed coffee) of caffeine every day, which will have the following effects on a person's alertness and mood. But when caffeine exceeds 400 mg (four cups), it will bring side effects, such as bad mood, irritability, aggression and trouble. If you only want to take polyphenols in coffee to resist oxidation, you only need to go to "fdecaf" coffee!
Studies have found that people who drink coffee are less likely to get Parkinson's disease. Scientists at the Veterans Management Medical Center in Honolulu, Hawaii, found that people who don't drink coffee are five times more likely to develop Parkinson's disease than those who drink more than five cups of coffee a day. Researchers have followed more than 8,000 men for 30 years, and their findings have been published in the Journal of the American Medical Association. Parkinson's disease (PD) is an senile disease with six kinds of pathological changes in the nervous system. Its typical symptoms include tremor, stiffness and decreased voluntary activities of limbs. It is not clear why researchers may reduce the risk of Parkinson's disease by drinking coffee. But they speculate that caffeine contained in coffee may play a role in preventing nerve cells that cause Parkinson's disease from being damaged. Scientists point out that their current results are preliminary and need further research to confirm. They stressed that it is too early to suggest drinking coffee as a treatment for Parkinson's disease.
