Focus on these simple, evidence-based shifts to lower your chronic disease risk
The Dietary Guidelines for Americans aim to translate the most up-to-date nutrition science into practical advice for the public as well as to guide federal policy for programs such as school lunches.
But the newest version of the guidelines, released on Jan. 7, 2026, seems to be spurring more confusion than clarity about what people should be eating.
I’ve been studying nutrition and chronic disease for over 35 years, and in 2020 I wrote “Sugarproof,” a book about reducing consumption of added sugars to improve health. I served as a scientific adviser for the new guidelines.
I chose to participate in this process, despite its accelerated and sometimes controversial nature, for two reasons. First, I wanted to help ensure the review was conducted with scientific rigor. And second, federal health officials prioritized examining areas where the evidence has become especially strong – particularly food processing, added sugars and sugary beverages, which closely aligns with my research.
My role, along with colleagues, was to review and synthesize that evidence and help clarify where the science is strongest and most consistent.
