TongRo Images/Thinkstock(NEW YORK) — A new study indicated that six genes in humans could be associated with increased coffee intake.
Previous research had found two human genes that impacted the metabolism of coffee, and the new study, published in the journal Molecular Psychiatry, identified six more. Researchers say that not only do these genes impact the way coffee is processed in the body, but they may also make genetic carriers more attracted to the prospect of drinking coffee.
Researchers did note, however, that those with these genes may drink 0.03 to 0.14 more cups of coffee per day — meaning the impact of these genes on coffee intake is small.
Some of the genes researchers say are associated with coffee intake have previously been linked in some way to smoking, obesity, blood pressure, diabetes, lipid profiles, and liver enzyme profiles. None of those factors, however, were linked to coffee intake in the study.
