The latest research showed that people sensitive to coffee bitterness tend to prefer coffee rather than avoid coffee. The preference for "bitter" is influenced by genes, and studies show that people who are sensitive to bitterness such as sprout cabbage are tea schools rather than coffee.

Marilyn Cornelis, who studies preventive medicine at the Northwestern University Feinberg Medical College, who studied, "Marilyn Cornelis, who is sensitive to bitterness, seems to be avoiding coffee, It has been shown that there will be a " positive reinforcement " by caffeine, so people will more like caffeine and acquire the ability to perceive bitterness. " Positive reinforcement means that the behavior is increased by presenting the preferred stimulus as a result of behavior. In general, "bittern" is a warning sign when people recognize harmful substances, so the fact that people with a high ability to perceive the bitterness of coffee, especially caffeine, learn it as "good" is surprising The researcher says that it was things.

This study was led by Mr. Jue Sheng Ong, Ph.D. student of genetics and computational biology at the Queensland Medical Science Institute, and how the genes are consumed in the consumption of beverages with strong bitterness such as tea, coffee and alcohol It was done to understand whether it is affecting.

"Every bitter may seem the same, but we perceive the bitterness of Brussels sprouts, the bitterness of tonic water ( Quinine ), and the bitterness of caffeine as distinctive How much do you feel about these bitterness Whether it is determined by genes, "Ong says.

Researchers surveyed relationships between genetic structure and daily bitter drinks in more than 400,000 people living in the UK. Using genes related to the ability to feel bittern, people who feel bitter tastes who have a high genetic tendency have examined whether they prefer bitterness of tea or coffee.

As a result, it turned out that those who have genes that perceive green vegetables such as Brussels sprouts and bitterns of tonic water prefer black tea rather than coffee. Also, people sensitive to the bitterness of quinine contained in tonic water and vegetables also tended to avoid coffee.

On the other hand, people with genes that perceive bitterness of bittern sprouts tended to not drink alcohol, especially red wine, compared with those without such genetic mutation. Such research results are expected to be useful for research on dependence.

In this study, the influence of things like cream and sugar has not been investigated. "There are many factors that people take coffee by thinking at the individual level.It is social status, metabolic power of caffeine, smoking habit etc. In addition, there are black and white There are a variety of things, including milk, cappuccino, "Mr. Ong said, and this research was surveyed with larger" coffee in general ".
