* In December 2024, the Scientific Report for the 2025-2030 Dietary Guidelines for Americans (DGAs) was published by the Dietary Guidelines Advisory Committee. This is the report that goes to the US Departments of Health and Human Services (HHS) and Agriculture (USDA) and, following other input, the 2025-2030 DGAs will be published later this year.
* The 2025-2030 publication will be the tenth edition of the DGAs.
* This note covers the background to the DGAs, when the Committee was formed, what the Scientific Report is and where it fits in the process, what has changed since last time and – ultimately – what is the recommended diet for Americans.
* I posit how the diet for Americans should be determined (which nutrients do human beings need to consume? and ii) which foods provide those nutrients?) and then question why this has not been done in 45 years of DGA committees. I explore competence, conflict, beliefs and what’s at stake to opine what went wrong.
