The bill aims to enhance the nutritional quality of school lunches in Massachusetts by establishing new standards and designating March 21 as Massachusetts Child Nutrition Day. It introduces a new section in Chapter 6 of the General Laws, which mandates the governor to issue an annual proclamation for this observance. Additionally, it amends Chapter 71 to ensure that food service management companies provide healthier meal options in public schools. Specifically, at least 50% of the entrees served must be healthy foods rich in whole grains, vegetables, fruits, and legumes, while limiting ultra-processed foods and those high in cholesterol and saturated fat.

Furthermore, the bill establishes a School Meal Nutrition Standards Advisory Council to guide the implementation of these new nutrition standards. This council will consist of 11 members, including school nutrition operators and representatives from various organizations, and will meet at least four times a year. The council's responsibilities include developing comprehensive nutrition standards, conducting feasibility assessments, and addressing barriers to implementation. The bill emphasizes transparency by requiring food service providers to maintain and publicly share itemized nutrition data monthly to demonstrate compliance with the new regulations.
