Healthy diets feature both whole- and refined-grain foods, new study shows
- Impact Area
Grain-based foods — both whole-grain and refined, from which the bran has been removed — are a key part of healthy diets, according to a study published in the science journal Advances in Nutrition.
The study, co-authored by Julie Miller Jones of St. Catherine University, Carlos Guzman of the Universidad de Córdoba and Hans-Joachim Braun of the International Maize and Wheat Improvement Center (CIMMYT), reviewed findings of more than 100 research papers from nutrition and medical journals as well as national health recommendations. It presents evidence for positive health impacts from diverse diets that include not more than 50% carbohydrates and the right mix of grain-based foods.
