Do you prefer to drink coffee or tea? One study shows that the answer to this question may be related in part to your genes. Our taste genes play a key role in determining the amount of coffee, tea or alcohol we drink. Our preference for drinking tea can be seen as a result of our abstinence from coffee consumption because our genes can make us feel that coffee is bitter than our taste, according to a new study by The Guardian. Scientists have explained that the genetic readiness to recognize the bitterness of certain substances plays a role in defining our approach to drinking a drink at the expense of another drink.
Are meals a gene?
"Our study increases our understanding of the factors that lead people to prefer to drink beverages at another cost," said Dr. Marilyn Cornelis, author of research at Northwestern University in Illinois. We still see differences in people's preferences for some beverages and the quantities we consume from these products. "The study, published in the Scientific Reports, included two sets of data, the first in two studies showing, at least in the European population, specific genetic variables related to our perception of different tastes.The first genetic variable is associated with slightly higher gall bladder rates for caffeine, the second variable has a higher rate of gallin quinine and third genetic variable is higher rate of bitterness of a drug known as propyl thyrosili.
In a second phase, the research team looked at the data from British Biobank, a study of hundreds of thousands of participants aged 37 to 73 between 2006 and 2010, which collected some genetic information and health information, including answers to a question about Different glasses of drinks that they drink every day.
Caffeine and bitterness of quinine
Scientists have found that people who have higher genetic predisposition to recognize the bitterness of caffeine drink more coffee. While people with greater awareness of quinine and propylene propers consume less coffee. These results were counterproductive when scientists looked at the relationship between genetic variables and their effect on people who ate tea.
The influence of knowledge on coffee and alcohol
"Although the effect of knowledge on the amount of coffee we drink daily may be relatively small and not more than 0.15 cups a day, it does more to you," said Joesheng Aung, head of the study of the Institute of Medical Research at University of Berghofer, Australia. It is preferred to become someone who drinks a lot of coffee, more than four cups a day, by 20%. "Scientists have also come to the conclusion that the stronger perception of the thyrosyl proline diode makes you less likely to be among those who drink too much alcohol.
Despite the limitations of the study, such as the adoption of the questionnaire, it can help to highlight our preferred drink.
What is the explanation?
"Because people tend to avoid drinks with bitter taste, we interpret these results as being obtained," said Marilyn Cornelis. If we are able to recognize caffeine well, it is related to the properties of activated caffeine. Therefore, it will prompt us to look for more coffee. "
But tea is not
"It's hard to explain the results for tea, but it's partly because people who drink too much coffee tend to be people who drink a little tea," Cornelis said. "Tea results can be due to tea containing small amounts of bitter substances, which means that its ingredients make it more suitable for coffee for people who are very bitter about the gallbladder," said Gui Sheng-ung.
