There are a number of obvious factors that affect how much coffee you drink. How much sleep do you have for example last night, or how many times have your needy cat woken up to you? Proximity to the nearest Starbucks to your office. The number of urgent and urgent stressful deadlines clog your diary. But before you chastise yourself for your complete caffeine addiction, here’s something else that plays an important role: your genetics. A new study has shown that the amount of coffee you drink is related to your genetically affected sensitivity to its bitter taste – and strangely the more sensitive you are, the more you will drink. Is not it a useful fact to be at your disposal next time your colleague is aiming for your fifth cup of the day?
Researchers from Northwestern University in the United States and the QIMR Berghofer Medical Research Institute in Australia studied the connection between our perception of coffee bitterness and how much of what we drink. Bitterness, the researchers pointed out, should deter us from drinking coffee and other bitter substances at all ̵
1; we still developed the taste to prevent us from consuming harmful things. And yet, a quick glance at the morning queue at the nearest cafe is enough to show that it is far from the case.

The study, published in Scientific Reports examined the relationship between sensitivity to the bitterness of caffeine and coffee consumption in over 400,000 people in Britain. The researchers were looking for a link between the presence of genetic variants associated with the sensitivity of the caffeine and the amount of coffee that the participants themselves reported drinking.
The results? The people who are more sensitive to the bitter taste of coffee drank more of it. “Given that people generally avoid bitter taste, we interpret these findings as possibly a learned behavior,” author Dr Marilyn Cornelis, from Northwestern, told Guardian . “If we can experience caffeine, we will associate it with the caffeine’s psychostimulatory properties and look for more coffee.” Simply put, if you’re more sensitive to coffee, you’re likely to associate it stronger with its precious energy effects – and drink much more as a result.

“Strong Caffeine Probes” is much more likely to become major coffee consumers, author Jue Sheng Ong, from QIMR Berghofer Medical Research Institute, explained. “While the effect of perception of your daily coffee intake can be relatively small – only a 0.15 cup per day increases – from a regular caffeine sampler to a strong caffeine test, it actually makes 20 percent more likely to be a big drinker – to drink more than four cups a day, “he told the guardian .
Taste, researchers say, not only at chance or the environment around you, but is strongly influenced by your genetics. Have you ever wondered why you need a constant supply of caffeine to do it all day, while Katie at the desk next to you seems good with her fruit-based water? The answer may appear in your genes. 19659009]
