History of USDA nutrition guidelines
open-in-new
<p>The history of USDA nutrition guidelines includes over 100 years of <a href="/facts/Human_nutrition/GntDW6oo">nutrition</a> advice promulgated by the USDA (<a href="/facts/United_States_Department_of_Agriculture/3PK2rx7C">United States Department of Agriculture</a>). The guidelines have been updated over time, to adopt new scientific findings and new public health marketing techniques. The current guidelines are the <a href="/facts/Dietary_Guidelines_for_Americans/dK56GDSP">Dietary Guidelines for Americans</a> 2020–2025. The 2015–2020 guidelines were criticized as not accurately representing scientific information about optimal nutrition, and as being overly influenced by the agricultural industries the USDA promotes. </p>
