Sugar-addicts beware; an affinity for sweets appears to be a marker for those at risk of developing alcoholism. While previous studies have found a sugar-alcohol link in both humans and animals, this study finds that sugar addiction may predict alcoholism.
Lead author Alexei Kampov-Polevoy, an assistant professor of psychiatry at Mount Sinai School of Medicine, recruited 163 college-age social drinkers. Half of the participants had a paternal history of alcoholism while the other half did not.
Kampov and colleagues asked each participant to rate a series of sugar solutions that increased in concentration. They judged each for sweetness and palatability. Our hedonic reaction -- how much we enjoy sugar -- is something we are born with, not something we learn later in life, notes Kampov.
