People Drink More Coffee as they are Sensitive to its Bitter Taste


If anyone holds his or her nose and then take a sip of coffee, they would not taste anything a liquid that has got a bitter taste. The reason is that most of the pleasure, which people get out of coffee, is through its flavor. Now a new study suggests that the sensitivity of people to the bitter taste of coffee plays a role in the amount of coffee they drink. Even though it seems to be quite counterintuitive, still the study shows that the more people are sensitive to the bitter taste of coffee, the more quantity of it they tend to drink.

A research team has conducted their analysis on the topic by making use of data, which is stored in something known as the UK Biobank. There have been more than 500,000 people, who have contributed samples of blood, urine as well as saliva to the biobank. These samples can help the scientists to answer different kinds of research questions. The researchers even used genetic analysis of samples from the biobank in order to find people who were more or less sensitive to the three bitter substances like caffeine, quinine and a chemical known as propylthiouracil. The researchers even found that people who were more sensitive to caffeine managed to report a higher level of coffee consumption compared to less sensitive people.

The result of the research was kept restricted to the bitter taste of caffeine. People, who were sensitive towards quinine and propylthiouracil, managed to drink less coffee. Surprisingly, none of the two components is present in coffee. Though taste plays some role in the way people consume coffee, an assistant professor at Northwestern University Feinberg School of Medicine, Marilyn Cornelis said the ability of people to break down coffee and flush it from the body is a much better way to predict as to how much they will drink. For all those, whose genes make them good in breaking down caffeine, actually, go on to drink more amount of coffee? It has even shown that those who drink two or three cups of coffee per day might go on to live longer as well.
