The purpose of the Dietary Guidelines Reform Act of 2025 is to update and improve the way dietary guidelines are developed in the United States. The goal is to ensure that these guidelines are based on the latest scientific evidence and are more relevant to public health needs. Key provisions of the Act include several important changes to how dietary guidelines are established. First, the frequency of updates to the dietary guidelines will change from every five years to at least every ten years, although updates can occur more frequently if necessary.
