Sarah Kliff summarizes a new study:
Drinking alcohol and eating snacks are far and away the most transmittable food behaviors, the longitudinal study finds. In fact, they’re the only food categories in which friends influence one another’s eating habits. Spouses, meanwhile, transmit these eating habits alongside many others: being healthier, avoiding caffeine, and consuming meat and soda. Brothers stand out as the only social relationship studied in which alcohol consumption wasn’t transmitted, but meat-eating was. For sisters, just alcohol and snacks came up as socially transmissible eating habits.
