How often are the Dietary Guidelines for Americans updated?

The Dietary Guidelines for Americans are updated every 5 years. This schedule allows for the incorporation of the latest scientific research and evolving health information regarding diet and nutrition. By updating the guidelines periodically, health officials can provide the most current recommendations to promote healthy eating patterns and reduce the risk of chronic diseases among the American population.

This regular update cycle ensures that the guidelines remain relevant and evidence-based, reflecting current knowledge about how different foods and dietary patterns can affect health outcomes. Such updates are particularly crucial as new research emerges, enabling public health officials to adjust recommendations in response to changing dietary trends, nutritional needs, and health issues impacting Americans.
