Kids often don't eat a healthy diet. They particularly don't get the 7+ servings of fruits and veggies they need every day. It is possible to puree these foods and slip them into other foods such as meat loaf, mac and cheese, and casseroles. This was done in public schools and the kids could not tell the difference, but they ate fewer calories and far more fruits and veggies.
Replacing food with too much carbohydrate, especially high fructose corn syrup, and unhealthy fats, with pureed veggies and fruits may help with the epidemic of obesity and type 2 diabetes as well as minimize the malnutrition many of our kids have.
