First lady Michelle Obama applauded food and beverage makers that have cut 6.3 trillion calories from their products since the launch of her Let's Move campaign. A coalition of 16 food brands including General Mills, Kraft Foods and PepsiCo spearheaded the calorie cuts. "Over the past five years we have truly changed the culture around health and living in this country," she said at the Partnership for a Healthy America Summit last week.
