The adage “You are what you eat” is considered to be fairly universal, but researchers at the University of Pittsburgh say it’s what you don’t eat that might make the bigger impact.

According to a new study, diets lacking omega-3 fatty acids can have negative effects over generations, especially on teens.

A team led by Bita Moghaddam, a professor of neuroscience at Pitt, found second-generation deficiencies of omega-3s caused heightened states of anxiety, hyperactivity and slower learning ability.
