If raw beans are roasted too heavily, they will produce substances similar to those found in cigarettes and may be addictive, but not caffeine addiction.

Some studies have shown that drinking too much coffee may increase the risk of high blood pressure, while other studies have shown that coffee can prevent diseases such as diabetes or dementia. Judging from such bipolar evaluation, people can't help but worry about whether to drink coffee or quit coffee. But coffee is different from the negative view in the past, on the contrary, it has many benefits. 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, caffeine will attach to the peripheral nerve, accelerate the smooth blood flow of the brain, promote brain activity and metabolism, and boost the spirit. However, everyone reacts differently to coffee. Some people only drink one cup of coffee and their heart beats faster and can't sleep at night.

In 2007, the Food, Medical and Drug Safety Agency pointed out that the recommended daily caffeine intake for adults is 400mg. 400mg's caffeine is equivalent to four cups of American coffee, six cups of three-in-one coffee, or five cans of coffee. More importantly, caffeine does not accumulate in the body. After a certain period of time, caffeine is excreted from the body.

It is said that caffeine is addictive, but this is not the case. The World Health Organization (WHO) also points out that caffeine is not a dependent substance. Only if the raw beans are roasted too heavily, they will produce some substances equivalent to cigarettes, leading to addictive symptoms. Among coffee drinkers, some people drink only a particular brand or are unable to work without that coffee, most likely due to addictive symptoms caused by heavy roasting of raw beans.

Caffeine is not actually addictive.

Caffeine is not regarded as an addictive substance in the international classification of diseases developed by the World Health Organization. Institutions that studied caffeine also found no dependence or abuse in caffeine.
