It’s possible that America’s biggest threat isn’t terrorism, economy woes or public health care. Instead, our most real threat is an epidemic spreading through the nation’s youth, childhood obesity. It’s estimated that one in five children are obese, marking the first time in recent years that children have a shorter life expectancy than their parents.

It’s commonplace for first ladies to find a public health issue to address. Nancy Reagan and her campaign on drug use is a great example of this. Currently, Michelle Obama is aggressively settting her sights on childhood obesity with her campaign named “Let’s Move.” Obama has set an ambitious goal of eliminating childhood obesity within a generation.

Currently, in our nation, one in three children are at risk of becoming obese. Not to mention that the percent of obese children has tripled in the past 30 years. Our nation also spends a staggering $150 billion each year on treating obesity related diseases.

Obama is striking childhood obesity from various angles including; giving parents support to influence their children’s lifestyles, healthier nutrition choices in schools, getting children more active and making healthy food more accessible. Obama has a comprehensive wealth of information on how to stop or deter obesity in children. The site tackles 4 major aspects of healthy living; healthy choices, healthier schools, physical activity and accessible and affordable food.

The first ladies’ site comes complete with a plethora of social media outlets including; blogs, youtube,  facebook and PSA videos. Let’s move even has a section that is devoted to informing children about living healthy. Complete with downloadable books, planners and videos.  Let’s move has also teamed up with the NFL’s Play 60 campain. Play 60 is aimed at getting children to play for at least an hour everyday, in an effort to fight childhood obesity.
