If you are a coffee lover, you know that the aroma is the main key.
A new study shows how the bitter taste of coffee influences people on how much they drink. An odd fact came as a result, the more sensitive someone is to the bitter taste, the more tends to drink.
Over 500,000 people were involved in this study, by giving blood, urine and saliva samples which were stored in the UK Biobank. There were some questionnaires to complete by the participants. The questions were related to health and coffee usage.
The bitter sensitivity is influenced by the genes acquired from our parents. So the data samples were taken from genetic analyses from people with a sensitivity of bitter substances: caffeine, quinine and a chemical called propylthiouracil. The next step in the research was to find out if these people drink more or less coffee than the ones who do not have any sensitivity.
The results were surprising for the researchers, as they show that people with sensitivity for the caffeine tend to drink increasingly more that those who are not sensitive. Even though the difference of the amount of coffee consumption was more just by two spoons of caffeine per day, the researcher spotted the small differences due to the big amount of collected data.
“Learn to associate that bitter taste with the stimulation that coffee can provide.”
Marylin Cornelis, assistant professor of preventative medicine at Northwestern University Feinberg School of Medicine said.
The conclusion of this study was that people who got genes that are good at breaking down caffeine tend to drink more coffee and surprisingly those who drink two or three cups a day might live longer.
