Michelle Obama: Happy 1st Birthday for 'Let's Move!'

“’Let’s Move!’ is far more than just a campaign, it’s so much more than just a slogan, this is a nationwide movement,” she told a large crowd at a church auditorium in Atlanta.

Obama deemed the program an early success, crediting the parents of America who insisted on more information on food labels, more affordable fresh fruit and vegetables and better food in school lunch programs.

“The truth is that executives at Walmart didn’t wake up one morning and decide to promote healthier products just for fun and folks in Congress didn’t write the most sweeping child nutrition legislation in decades because they had extra time on their hands,” she said, “They did this because folks like us stood up and asked for those changes.”

Last month Walmart, one of the nation’s largest grocers, pledged to cut 25 percent of the salt and 10 percent of added sugars in processed products by 2015 as well to cut $1 billion in costs to lower the prices of fresh food.

In addition, Obama said they’re putting salad bars in 6,000 schools, enlisted 2,000 professional chefs to help make school menus more healthy. And they recruited professional athletes to star in commercials that promote exercise and eating right.

“If we can do all this in just one year, just imagine what  we’ll achieve next year,” she said.
