The purpose of the Dietary Guidelines Reform Act of 2025 is to update and improve the dietary guidelines established under the National Nutrition Monitoring and Related Research Act of 1990. The goal is to ensure that these guidelines are based on the latest scientific evidence and are more relevant to the health needs of the population. Key provisions of the act include changing the frequency of updating the dietary guidelines from every five years to at least every ten years. This allows for more thorough and evidence-based reviews.
