PARIS, France – In a new research that examines how genetic factors determine taste, scientists now believe they know why some people prefer coffee while others choose tea.
A paper published this week in the Nature Scientific Reports magazine found that people who have been inherently like bitter flavors usually choose coffee because of its higher content of tart caffeine.
But, most importantly for tea drinkers everywhere, that does not do it right.
As people develop, the ability to detect bitterity as a natural warning system has been developed to protect the body from harmful substances.
Speaking in evolution, we should want to trigger the American immediately down the sink.
But participants in the more genetic trial were more sensitive to bitter caffeine flavor more likely to be better from coffee to tea, and more likely to drink more of it.
"You should expect people who are particularly sensitive to bitter caffeine tastes to drink less coffee," said Marilyn Cornelis, an assistant teacher of preventative medicine at the Northwestern Feinberg School of Medicine.
"The other results of our study suggest that coffee consumers acquire a taste or ability to find caffeine due to the positive reinforcement learned by caffeine."
So those who are pre-programmed genetically to like bitter coffee learn to connect "good things with him," says Cornelis.
In the study of more than 400,000 men and women in the United Kingdom, researchers also found that people who are sensitive to bitter cuisine flavors and flavor associated with vegetable compounds are more likely get rid of coffee in favor of its similar tea, tea.
Liang-Dar Hwang from the University of Queensland, Diamantina Institute, who co-wrote the study, told AFP that the fact that some people prefer coffee shows how everyday experiences can ignore genetic trends when it comes to taste.
"The bitter taste perception is formed by not only genetics but also environmental factors," he said.
"Although people naturally like bitterness, we can learn or enjoy bitter tasty food after we come into contact with environmental factors."
Although the love of coffee is basically evolving evolution, there is another possible benefit to like your latte.
Hwang said coffee drinks were less sensitive to bitterness than the warmers of tea, making them "less likely to hate other bitter tasty foods" such as green vegetables. / cbb
