Earlier this month, the nonprofit Physicians Committee for Responsible Medicine (PCRM), filed a petition asking the USDA to remove milk as a required food from the national school lunch program. The PCRM petition argues that milk should not be included as part of a healthy school lunch because one in eight Americans is lactose intolerant, there is limited proof that milk improves bone health or reduces the risk of osteoporosis, and because dairy can lead to other health risks, among other reasons.
