How often are the Dietary Guidelines for Americans updated?

The Dietary Guidelines for Americans are updated every 5 years to reflect the latest scientific evidence on nutrition and health. This biennial review process involves a thorough evaluation of current research, allowing for necessary adjustments to recommendations regarding dietary intake and overall health practices. The 5-year interval ensures that the guidelines remain relevant and based on the most current understanding of nutrition science, public health issues, and changing dietary patterns in the population.

This systematic approach facilitates the incorporation of new findings, enabling health professionals, policymakers, and the public to make informed decisions about dietary guidelines that can positively influence health outcomes.
