The 2025–2030 Dietary Guidelines for Americans are drawing sharp criticism from liver specialists. A new study published in the American Journal of Gastroenterology, analyzing data from nearly 11,000 adults in the National Health and Nutrition Examination Survey (2017–2023), found that several elements now emphasized in the guidelines — including high total protein intake and red or processed meat — are associated with greater prevalence of steatotic liver disease (SLD) and fibrosis.

Meanwhile, components that were removed from the updated guidelines — such as recommendations for greens, beans, seafood, and plant-based proteins, plus specific alcohol limits — were found to be protective for liver health. Researchers noted that limited alcohol use was "strongly protective" for all liver outcomes, making the omission of clear drinking limits a significant concern for the liver community.

Key Takeaways:

• A clear protein source hierarchy emerged for liver health: plant-based > seafood > poultry > red meat
• Removing alcohol limits (previously: ≤2 drinks/day for men, ≤1 for women) leaves patients without critical guidance
• For patients with cirrhosis, protein intake of 1.2–1.5 g/kg/day is still recommended, but should favor plant and seafood sources
• The updated guidelines no longer distinguish protein by source, and experts warn this could be misinterpreted as a green light for red meat consumption

Why it matters: Millions of Americans rely on federal dietary guidelines to make everyday food choices. When those guidelines overlook liver-specific risks — especially around protein type and alcohol — clinicians are left without clear tools to counsel patients, and patients may unknowingly increase their risk of serious liver disease.
