With regard to "mood" drinks, people are classified into two types, tea lovers and coffee lovers. How is the human preference for one of these popular drinks?
In this regard, a recent study found that the taste genes found in humans are responsible for the preference of coffee or tea drink.
Researchers from the University of Northwestern, Illinois, said that the genetic predisposition to recognize the bitterness of certain substances leads us to choose a drink, which applies to tea and coffee.
"The study adds important information to our understanding of the motives for selecting a particular beverage, especially taste, and why the individual insists on choosing the drink itself after changing the ingredients in its preparation, without compromising the taste factor," the British Guardian website quoted Dr. Marilyn Cornelis as saying.
People with a greater genetic predisposition to the perception of caffeine bitterness tend to pick and drink large amounts of coffee, while the decreased sense of bitumen alkaline quinine has been associated with a decrease in appetite for coffee, according to the study, published in the Scientific Reports.
Even a modest increase in the daily cup of coffee contributes to the transformation of the drinker from "plain drinker" to "strong tasting", which takes up almost four cups a day.
With regard to tea, the study found that those who drink coffee with greed often tend to be "tea drinkers pale", because of the difference in the degree of gallbladder drink and concentrated in coffee more intensively.
