What are the advantages and disadvantages of drinking coffee to the human body? I think everyone can search for a lot of more unified answers on the Internet. Generally speaking, the benefits and disadvantages of coffee are roughly the same as those stated online. However, with the in-depth study of coffee ingredients by scientists in various countries in recent years, more little-known benefits of coffee have been discovered. Here are some of them to share with you.

Coffee Benefits 1: Decaffeinated Coffee Can Mutual Liver

Previous studies have shown that coffee may help reduce the risk of diabetes, heart disease, fatty liver disease without alcohol, cirrhosis, liver cancer.

Dr. David Bernstein, chief of liver disease at North Shore University Hospital in New York, points out that "several studies have suggested that drinking coffee protects the liver and even prevents the development of liver cancer," and that these studies are interesting and the notion that coffee protects the liver is a tough one to prove,"he stresses.

"Perhaps the most important message from this study, which points out that caffeine doesn't have a protective effect, actually does some research on the intrinsic components of coffee itself," Bernstein said.

"With this information, it will be important for future research to study the composition of coffee in the hope that its protective factors can be produced and used in patients with liver disease," he said.

Coffee benefit 2: Coffee can protect eyes

A new Cornell University study found that drinking a cup of coffee a day reduces the risk of retinal degeneration caused by aging, diabetes and glaucoma. The retina is the most metabolically active tissue in the body, a thin layer of tissue composed of many photosensitive and nerve cells on the back wall of the eyeball. Oxygen deficiency and free radical production in the body can cause retinal damage. Green coffee contains about 9% chlorogenic acid, a highly effective phenolic natural antioxidant that can effectively prevent retinal degeneration.

Coffee Benefit 3: Drinking coffee before exercise helps fat burn

Professor Suzuki divided the subjects into three groups in the study, namely,"exercise after drinking boiled water","exercise after drinking coffee" and "standing after drinking coffee". One hour after drinking a cup of boiled water or a cup of coffee, they ran for 30 minutes (equivalent to moderate intensity running on a treadmill).

Professor Suzuki explained the results of the study: "One hour after drinking coffee, sympathetic nerves are in an excited state, and free fatty acids in the blood change to an energy-supplying form and increase in concentration." In addition, the fat burning index (respiratory quotient) can last up to 5 hours." Even if you just stand and don't exercise after drinking coffee, you can also find that energy metabolism increases."If you start exercising after drinking coffee, the effect of energy metabolism will be better and more lasting."

Coffee Benefits 4: More than 2 cups a day can prevent freckles

Coffee contains polyphenols that can improve the body's ability to resist acidification, thus preventing freckles. Studies have shown that people who drink more than two cups of coffee a day have fewer freckles, and the polyphenols also protect against UV damage.

Coffee also has the effect of controlling blood pressure and preventing arteriosclerosis. Coffee, which is considered to be the enemy of beauty, will bring good auxiliary effects to beauty and weight loss as long as it is ingested in moderation. Of course, if you don't have time to make coffee, you can also choose a more famous coffee drink. For people who don't drink coffee, can you try to let coffee into your life?
