Love for coffee depends on the genes

The journal Scientific Reports published the results of the study that explain why many people have a maniacal love for coffee, despite it, in essence, unpleasant bitter taste. Its authors, scientists from northwestern University in Chicago, concluded that the love for coffee depends on genes – or gene mutations.

As follows from their report, certain gene mutations contribute to the fact that the person in particular feels the bitter taste of coffee, which seems to him anything but just not repulsive or unpleasant. Gradually he gets used even to the very bitter taste of coffee and begins to enjoy the recognition of inherent notes and shades – so there is love to drink.

According to the authors, the results of their genetic analysis surprised them. It turned out that the greatest love of coffee people experience, whose genome has gene variations associated with high sensitivity to caffeine. Although such sensitivity as one would initially assume, could make the coffee too bitter to the taste.

“The bitter taste of foods and beverages usually serves as a warning to mammals about the content of dangerous substances. The love for coffee that occurs due to genetic mutations, appears as something “unnatural” from an evolutionary point of view,” said the authors of the project.
They also found that carriers of the coffee gene mutations are not particularly fond of tea and small compared to the other drink alcohol.
The researchers suggest that differences in the perception of tastes caused by similar mutations in genes can affect human behavior. Further study, according to them, can reveal hiding until now the nature of taste sensations.
