Do you like coffee? Then it may be due to your genes. Scientists have found six new genetic variants associated with habitual coffee drinking. The new findings could explain why some people crave coffee in the morning, while others are less prone to seeking out the brew.
"Coffee and caffeine have been linked to beneficial and adverse health effects," said Marilyn Cornelis, one of the researchers, in a news release. "Our findings may allow us to identify subgroups of people most likely to benefit from increasing or decreasing coffee consumption for optimal health."
