Recent studies have suggested that drinking too much coffee may increase the risk of high blood pressure, and studies have shown that coffee can prevent diseases such as diabetes or dementia. From such a bipolar evaluation, people can not help but start to worry about whether to drink coffee or quit coffee. But coffee does have many benefits, contrary to the negative perception. First of all, let's start with the misunderstanding of coffee.

Caffeine is a colorless and odorless bitter ingredient. After being absorbed by the body, it will attach to the peripheral nerves, accelerate the smooth blood flow in the brain, promote brain activity and metabolism, and have the effect of boosting the spirit. However, everyone reacts differently to coffee. Some people drink only one cup of coffee and their heart beats faster and they can't sleep at night.

In 2007, the Food and Drug Safety Agency stated that the recommended daily caffeine intake for adults was 400mg. 400mg of caffeine is equivalent to 4 cups of American coffee, 6 cups of three-in-one coffee, or 5 cans of canned coffee. More importantly, caffeine does not accumulate in the body, ingested into the body after a certain period of time, will be excreted.

There is a saying that caffeine is addictive, but this is not the case. The World Health Organization also states that caffeine is not a dependent substance. It is only when the raw beans are over-roasted (instant coffee, for example) that they produce substances equivalent to those in cigarettes that addictive symptoms occur. Some coffee drinkers will drink only a certain brand of coffee, or will not be able to work without drinking that coffee, most likely due to the addiction caused by heavy roasting of raw beans.

Caffeine is not addictive.

Caffeine is not considered an addictive substance in the International Classification of Diseases established by the World Health Organization. Authorities studying caffeine also found no dependency or abuse in caffeine.
