Folks who want to eat healthy by choosing whole grain foods aren't helped by product labels that can confuse and mislead consumers, a new study shows. Almost half were unable to identify the healthier whole grain option when asked to rely on food package labels, researchers discovered. A similar proportion of participants were unable to accurately state the whole grain content of different products, according to the study. Terms like "multigrain," "contains whole grains," "honey wheat" and "12-grain" can be used to hawk breads, cereals and crackers as healthier options even if the product mostly contains refined flour, explained lead researcher Parke Wilde, a professor at Tufts University's School of Nutrition Science and Policy in Boston.
