Coffee is good for our health. Coffee energizes us.

Coffee energizes us.

The content of caffeine does not come from the taste, but is closely related to its brewing method. Recent studies have shown that coffee contains a large number of antioxidants, pain-relieving compounds and antibacterial compounds. Of course, that doesn't mean you can drink as much as you want-it's the opposite. However, it is necessary to understand the benefits of having a cup of coffee every morning.

Concentrate

Coffee can make you think better. Caffeine, often described as the world's most widely used mood mediator, produces the opposite effect of adenosine as a sedative. Studies have shown that coffee can make you more focused, especially when you are doing boring work. "when you don't get enough sleep, caffeine can improve the performance of a range of cognitive tests, such as mobility, memory, learning and attention," said Dr. Harris Lieberman, chief caffeine researcher at the United States Army. Coffee can also improve your mood and make you feel more energetic. "

Reduce the feeling of sleepiness

French researchers recently conducted a test in which volunteers were organized to test drugs during an eastward flight across the Atlantic. Volunteers who took caffeine felt much less sleepy than those who took N-acetyl-5-methoxysolan (or placebo). The researchers suggest that drinking a cup of coffee every two to three hours from breakfast to four to six hours before going to bed can reduce drowsiness and make people more alert.

Enhance the athletic ability

A new study shows that caffeine can reduce the pain caused by muscle exercises, so that you can increase the intensity and time of exercise. To achieve the best pain relief, you only need to drink 450 grams of coffee before exercise. A small amount will also play a role, but be careful not to drink too much.

Strong teeth

Drinking coffee can reduce the number of times you go to the dentist. Recently, researchers in Italy have found that the antibacterial ingredients in coffee can slow the growth of Streptococcus, which is responsible for tooth decay. The compounds in coffee can also reduce the chances of bacteria sticking to the surface of teeth. Studies have shown that drinking coffee can reduce the formation of dental cavities.

Removal of stones

It's no secret that coffee can make your bladder healthier. The Nursing Health Association claims that coffee can also reduce the risk of kidney stones. In general, the more coffee women drink, the lower the risk of kidney stones. Caffeine can reduce the risk of kidney stones. Decaf has a similar effect.

Stay away from Parkinson's

New research shows that drinking just one cup of coffee a day can reduce the risk of Parkinson's, a brain disease that causes tremors. Women with 1ax 50 are at risk of suffering from the disease. Alberto Ascherio, MD, associate professor of nutrition and epidemiology at Harvard University, said: "caffeine protects brain cells from Parkinson's disease."

Stay away from diabetes

A recent survey found that women who drink three cups of coffee a day can reduce their risk of developing type 2 diabetes by 20 to 30 points. Experts believe that antioxidants in coffee are the key. Dr. Frank Hu, Associate Professor of Nutrition and Epidemiology at Harvard University, pointed out that coffee can help promote the transfer of insulin to tissues. Insulin resistance-the main cause of diabetes-coffee can reduce the likelihood of it.

Cancer prevention

Japanese researchers point out that people who drink coffee every day for ten years are 50% less likely to develop liver cancer than those who never drink coffee. And the more you drink, the lower the risk of liver cancer. Researchers have yet to figure out whether caffeine is at work.
