Im not sure how Michelle Obamas changes were negative? Seems that 2018 started rollbacks.
Since improved nutrition standards for school meals were put into action across the United States in 2012, children – especially those from low-income households – have been eating healthier school lunches with better overall nutritional quality, a study published July 28 in JAMA found.

From the article:
The Healthy, Hunger-Free Kids Act changed nutrition standards for the National School Lunch Program by requiring that schools serve more fruits, vegetables, whole grains and fat-free and/or low-fat milk more frequently and less starchy vegetables or foods high in sodium and trans fat. The Obama-era policy has since seen a series of rollback measures.
The U.S. Department of Agriculture (USDA) altered the nutritional standards in 2018 to allow for fewer whole grains and more sodium and flavored milk. Then in January 2020, shortly before schools closed in response to COVID-19, the department proposed yet another set of changes to the policy to reduce the servings of vegetables students had to eat every week.
