Advantages and Disadvantages of Coffee (Caffeine)

First, let me introduce the benefits of coffee (caffeine)

• Coffee lowers the risk of developing cancer - how medicine lowers the risk of developing cancer is not yet fully understood in medicine. However, it has been reported that those who become accustomed to drinking coffee have a lower incidence of oral, breast, liver, and prostate cancers.

  Coffee is rich in antioxidants is one of the factors that lowers cancer risk, but it does not seem to be the only one.

• Coffee (caffeine) activates brain and muscle - caffeine in coffee is probably one of the most famous chemicals. And, "caffeine is effective in preventing drowsiness" is something that everyone has heard about once. By the way, caffeine has the effect of activating not only the brain but also the muscles of the whole body and making it hard to feel tired.

  Caffeine works by preventing "adenosine" from binding to "adenosine receptor" in the human body. When adenosine binds to the adenosine receptor, the nerve is sedated, and caffeine that blocks this binding (reduces nerve sedation) can result in nerve excitation. Also, at this time, adrenaline is secreted from the brain, which causes the brain and the muscles of the whole body to become more excited, and the head becomes clearer and the athletic ability increases.

• Coffee is effective in treating and preventing alcoholism - Studies have shown that coffee is effective in treating and preventing alcoholism.

  It is said that coffee does not act directly on alcohol, but rather activates the liver, which is responsible for breaking down alcohol.

  • Some researchers have questioned the theory that coffee is effective in preventing alcoholism.

• Coffee is rich in antioxidants - "Reactive oxygen" is said to be the cause of aging of the skin, brain and internal organs, and has a major relationship with the development of cancer. Reactive oxygen is very toxic to the human body.

  And "antioxidant" is a general term for "a component that counteracts the action of highly toxic active oxygen". Coffee is rich in antioxidants!

  It is often said that fruits and vegetables are rich in antioxidants and are good for beauty and health, but they are far from the antioxidant effect of a cup of coffee.

• Drinking coffee before exercising has an advantage in sports that require endurance - Caffeine works by raising the fatty acid level in the blood.

  Drinking coffee before exercising is particularly advantageous in sports where endurance is needed, as muscles can burn fatty acids and create energy.

  • In international games such as the Olympics, if you take caffeine equivalent to 6 cups of coffee 30 minutes before the start of the game, you may get a doping judgment. Be careful if you drink coffee before the competition.

• Coffee (caffeine) has a fat-burning diet effect - Caffeine has the effect of promoting the action of new metabolism in the body by 3 to 10%.

  Since fat burning is also promoted, coffee (caffeine) can be expected to have a diet effect.

The following introduces the disadvantages of coffee (caffeine)

• Can cause gastrointestinal inflammation - coffee has been shown to cause gastrointestinal harm. In particular, drinking a cup of coffee on an empty stomach can cause gastric ulcer, gastritis, and diarrhea!

  However, coffee enthusiasts say that the pain of gastritis is not a problem compared to the euphoria of drinking coffee.

• Has a diuretic effect - caffeine is known to have an intense diuretic effect. Therefore, it is safer to avoid drinking coffee for the purpose of hydration. Even if you drink fresh water with coffee, the water in the body will come out with pee, so the body will not be rehydrated much. Also, if you go to work after drinking coffee after breakfast, the diuretic effect will work just inside a crowded public transport or while driving your car.

• Drinking coffee makes your teeth yellow and dirty - coffee, like some carbonated drinks, is a great enemy for tooth beauty. The color of the coffee itself and the sugar content in the coffee, such as syrup and creep, increase the risk of tooth decay and tend to cause stains (yellowing of the teeth).

• Increases risk of miscarriage and fetal disability during pregnancy - caffeine passes through the placenta, the natural barrier that protects the fetus. As a result, coffee consumption during pregnancy, even with just one cup per day, increases the risk of fetal childhood leukemia and growth disorders.

  In addition, since the fetus does not have enzymes that break down and excrete caffeine, it seems that metabolites of caffeine that has entered the body of the fetus accumulate in the fetal brain.

• The world's most expensive coffee is made from elephant dung - black Ivory, the world's most expensive coffee, is made from elephant dung. Feeding the coffee beans to the elephant with the food and it will be fermented in the elephant's body. After that, coffee beans are washed and dried. So you might think twice before drinking black ivory.
