Global review of whole grain definitions and health claims

Abstract

Abstract Recommendations to increase whole grain consumption are part of dietary guidelines around the world. To assist consumers in meeting this recommendation, some countries, and health-promoting organizations, have defined qualifying criteria for a whole grain food for product labeling or health claims. Other countries have not yet developed similar guidelines. Existing whole grain definitions and health claims are reviewed here. While there appears to be increasing consensus for defining a whole grain, significant disparity exists in defining a whole grain food when a product is not 100% whole grain. Moreover, while whole grain health claims have been approved in a few countries, other countries have concluded there is insufficient evidence to substantiate such claims.
