Hot on the heels of the second anniversary of her “Let’s Move!” campaign, first lady Michelle Obama is gracing the cover of the journal “Childhood Obesity” in a special edition featuring a forward by the first lady and a piece from Agriculture Secretary Tom Vilsack about the Healthy, Hunger-Free Kids Act of 2010 — which focuses on improving nutrition standards for school lunches. The issue, which is available in print and online, features articles about treating and preventing childhood obesity with BMI screening in schools, after-school obesity prevention programs, better nutrition standards for school lunches, gaming and technology for weight control, a “roundtable discussion” about some of the mysteries surrounding the epidemic itself, and success stories from the first lady’s “Let’s Move!” campaign.
