Review of whole grain and dietary fiber recommendations and intake levels in different countries.Nutr Rev. 2020 08 01; 78(Suppl 1):29-36.NR
This review of whole grain and dietary fiber recommendations and intake levels was presented at the symposium on whole grains, dietary fiber, and public health, convened in Beijing, China, on May 11, 2018. The review reflects on inconsistencies among the definitions of whole grains and fiber as well as recommended intake levels in different countries. The lack of consistent dietary recommendations from authoritative sources may delay the regional implementation and consumer adoption of diets that include whole grains and fiber. Currently, few countries include specific intake recommendations for whole grain, and even among those countries with guidance the recommendations can be vague and qualitative. As a result of the well-documented associations between increasing whole grain intake and reduced disease risk, there is compelling evidence to create clear, actionable dietary recommendations for both whole grains and fiber. Furthermore, work is ongoing to develop uniform standards for whole grain and whole-grain food to ensure recommendations are being met. Health and regulatory authorities are encouraged to acknowledge the public health benefits that could be derived from strong, clear whole-grain and dietary fiber recommendations; examine existing definitions (whole grain as an ingredient, whole-grain food, and dietary fiber); and adopt the most appropriate approach to best serve public health needs for their respective populations.
