"This study is based on a very large number to show that the perception of bitterness affects the consumption of tea or coffee," said Daniel Liang-Dar Hwang of the University of Brisbane, one of the study's authors.
Strangely, it is precisely the people who are most sensitive to the bitter taste of coffee who drink most of the coffee. This shows & # 39; that coffee drinkers develop a feeling or ability to detect caffeine & # 39 ;, Marilyn Cornelis, professor of preventive medicine and study co-author.
"Genetics is responsible for a slightly higher level of sensitivity to bitterness than the perception of sweetness," said Daniel Liang-Dar Hwang. But the perception of tastes is also influenced by our behavior.
& # 39; Even though people naturally don't like bitter taste, we can learn to appreciate bitter food. Because coffee drinkers generally can tolerate bitter taste better, they will also appreciate the bitter taste of other foods such as green vegetables, "the researchers said.
This study was based on genetic data of around 438,000 Britons who participated in this study. This can not only be generalized to other countries and cultures, the authors said.
