Summary
This study analyzes the environmental impact of the 2025–2030 Dietary Guidelines for Americans, which recommend avoiding ultraprocessed foods while increasing protein intake primarily from animal sources. The research quantifies that adherence to these new guidelines would result in higher greenhouse gas emissions, freshwater use, land use, and nitrogen fertilizer use compared to previous guidelines, highlighting the environmental trade-offs of current dietary recommendations.

· 3 pulledDietary guidelines form the foundation of federal food policy, informing programs such as the Supplemental Nutrition Assistance Program (SNAP), government food procurement, school meals, and military and hospital food services.
The most recent guidelines, released in early 2026, advise avoiding 'hyperprocessed' (generally known as ultraprocessed foods, UPFs), while also recommending higher overall protein intake chiefly from animal sources.
Here, we quantified the greenhouse gas (GHG) emissions, freshwater use, land use, and nitrogen fertilizer use of adherence to these new guidelines
