People love coffee and beer for the buzz, not the taste – study

The truth may be that our preferences for caffeine or alcoholic beverages — or indeed sugary sodas — derive not so much from the way they taste but how they make us feel, according to a new study by genetic scientists at Northwestern University that was published in Human Molecular Genetics on Thursday.

But to her and the team’s surprise, people’s preferences weren’t based on variations in taste genes but rather the genes that are related to the beverages’ mind-altering effects. The researchers then performed a genome-wide association study of the consumption patterns, which were in turn validated in three US populations.Coffee, because of its bitterness, “is something which we should be avoiding on an evolutionary level,” she said. “But we’re consuming it because we learned to equate the taste with the caffeine effect.”

Calling the finding “counterintuitive,” Cornelis said: “FTO has been something of a mystery gene, and we don’t know exactly how it’s linked to obesity.The study’s overall findings could eventually help researchers find ways to intervene when consumption patterns become unhealthy.
