With Treasury Secretary Tim Geithner and USDA Secretary Tom Vilsack in tow, First Lady Michelle Obama traveled to Philadelphia yesterday as part of the Let's Move! campaign, a nationwide effort to rally the country around one goal, ending the epidemic of childhood obesity.

During her remarks at Fairhill Elementary School, Mrs. Obama applauded the city of Philadelphia for their "stand" to end childhood obesity:

Six years ago, when this city had fewer supermarkets per person than almost anywhere in America, all right, that was six years ago, when many folks had no access to healthy foods; six years ago many neighborhoods had alarming rates of obesity-related conditions like heart disease and diabetes -- the folks in this city, you all could have decided that you had an unsolvable problems on your hands, right? You could have done that. You could have decided that these problems were just too big and too complicated and too entrenched and thrown your hands up and walked away.

But instead you all took a stand, a really important, collaborative stand. You decided first that no family in this city should be spending a fortune on high-priced, low-quality foods because they have no other options. You decided that no child should be consigned to a life of poor health because of what neighborhood his or her family lives in. And you decided that you weren't going to just talk about the problem or wring your hands about the problems, but you were going to act.

And that's precisely the kind of determination, the kind of commitment that we need to address the epidemic of childhood obesity in this country. And this issue is an issue of great concern to me, and I've said this before, not because I'm First Lady -- or not just because I'm First Lady of this country -- but because I'm a mother, and I care about my kids and I care about all of our kids. And I know that this issue is a great concern to all of you, everyone around this country. We all care about our kids. That's why last week we enthusiastically and proudly launched "Let's Move." (Applause.) "Let's Move" is a nationwide campaign to rally this country around one single but ambitious goal, and that is to end the epidemic of childhood obesity in a generation so that the kids born today grow up with a healthy weight. Simple but ambitious.

Mrs. Obama also announced a new part of Let's Move! -- the Healthy Food Financing Initiative, a multi-million dollar public and private investment to eliminate food deserts in America within seven years:

So with your success here in Pennsylvania, what you've shown us is that when we provide the right support and incentives, then business leaders like Pat Burns and Jeff Brown, they're going to take the chance to invest in our communities. And when we bring fresh, healthy food to communities, what do we learn? People will buy it, right? People will buy it. These stores are turning a profit. And what's going on is that they're doing well by doing good. Isn't that something? (Applause.)

So it's because of this example that part of "Let's Move" we created this Healthy Food Financing Initiative that's modeled on what's been going on here. And as Secretary Geithner said, with a modest initial investment of about $400 million a year, we're going to use that money to leverage hundreds of millions more from private and non-profit sectors to bring grocery stores and other healthy food retailers to underserved communities all across this country. If you can do it here, we can do it around the country. (Applause.) And our goal is ambitious. It's to eliminate food deserts in America completely in seven years. (Applause.)

Again, we know this is ambitious, but we also know that tackling the issue of accessibility and affordability is key to achieving the overall goal of solving childhood obesity in this generation.
