A new study shows most American adults are unaware that FDA’s nutrition labels are based on 2,000-calorie-a-day diets, though a simple text message reminder can go a long way.
Researchers at the Johns Hopkins Bloomberg School of Public Health surveyed 246 participants dining at the hospital cafeteria to assess their initial knowledge of the 2,000-calorie value. Food in the cafeteria included calorie labels but no information on daily context. Over the course of four weeks, participants were randomly assigned to receive reminders of the calorie value through text, email or none at all.
