American Society for Nutrition Advocates for Robust Scientific Support in Nutrition Guidelines

Strong Advocacy for Scientific Integrity in Nutrition Guidelines

The American Society for Nutrition (ASN) recently voiced their support for the Dietary Guidelines for Americans (DGAs) for 2025-2030, which advocate for a balanced eating pattern focusing on minimally processed and nutrient-dense foods. ASN highlights the importance of dietary approaches that prioritizes whole foods while reducing reliance on highly processed items and sugar-laden beverages. This emphasis on nutrient-rich eating is linked to improved health outcomes over time.

However, ASN has expressed significant concerns over recent changes in the scientific review process that underpins these guidelines. The organization believes that moving away from established scientific review frameworks threatens the integrity of the DGAs, leading to public confusion and distrust. ASN points out that the introduction of a separate Scientific Foundation for the Dietary Guidelines report—rather than using the traditionally relied-upon Scientific Report from the 2025 Dietary Guidelines Advisory Committee (DGAC)—represents a substantial break from established methods.

The ASN has criticized the lack of transparency regarding the methodologies and timelines in these newly introduced scientific reviews. The organization stresses the necessity for a clear, trustworthy approach to developing nutrition guidelines, as this is vital for fostering public confidence in nutrition science. “Transparency is key for the public, stakeholders, and researchers to engage productively with these guidelines,” stated an ASN representative. This shift from historic, rigorous evidence review processes not only raises red flags concerning the DGAs' credibility but also limits opportunities for constructive scientific discourse.

In previous iterations of the DGAs, the Scientific Report of the DGAC has played a critical role, serving as the primary evidence base for forming dietary guidelines. The independent panel of experts involved in the review process has historically adhered to best practices endorsed by the National Academies of Sciences, Engineering, and Medicine. ASN firmly believes that these systematic reviews and the thorough examination of evidence should remain the foundation for developing public nutrition policies.

One significant point of contention raised by ASN revolves around the apparent inconsistencies in the DGAs. For instance, while the 2025-2030 DGAs continue to advise that saturated fat intake be limited to no more than 10% of total daily calories, they simultaneously suggest inclusivity of foods rich in saturated fats, like butter and beef tallow. ASN warns that this contradictory messaging could confuse consumers, complicating their efforts towards maintaining long-term health practices.

ASN strongly advocates for nutrition guidance that leans on scientific findings and articulates its evidence review process clearly. The effectiveness of the Dietary Guidelines hinges on their implementation ease and their applicability to the entire U.S. population. Implementing guidelines that lead to significant health improvements necessitates supportive policies and food environments that facilitate easier and more affordable healthy choices.

In addition to these discussions, ASN welcomes the recognition within the DGAs of the ongoing necessity for investment in nutrition research. Following the release of the DGAs, it has been acknowledged that funding for nutrition research remains inadequate. ASN argues for increased targeted funding to address diet-related chronic diseases through governmental bodies such as the USDA, CDC, and NIH, thereby ensuring future evidence-based dietary guidance.

Founded in 1928, ASN stands as a leading organization for nutrition research scientists and clinicians, uniting close to 8,000 professionals globally. The society emphasizes the importance of collaborative efforts among nutrition scholars, policymakers, and industry figures to enhance the collective understanding and application of nutritional science. ASN publishes four peer-reviewed journals while providing education and professional development opportunities to foster advancements in nutrition research and practice.

As the conversation on dietary guidelines progresses, ASN remains committed to advocating for scientific processes that uphold rigor and transparency, ultimately working to maintain public confidence in nutrition guidance.
