America faces an obesity epidemic. 68% of adults and nearly one-third of children are considered at least overweight. Childhood obesity is at such high levels that First LadyMichelle Obama has started a national program called ‘Let’s Move’ to help reverse the trend. Lack of exercise, too much sugar added to too many foods, a lack of healthy food choices in schools and workplaces, urban food deserts, and a lack of understanding of how to choose and prepare healthy, low-fat foods have all been blamed.
