Across the country this morning, kids are heading off to their first day of school. Hopefully, they're hitting the books with a solid, nutritious breakfast in their stomachs. Research shows that not only do breakfast eaters tend to eat fewer calories overall during the day, but kids who eat breakfast are more alert, do better academically, and feel better all around.

Not everyone is a morning person, however, and not everyone is a breakfast eater. That can make getting a good breakfast into a child or teen challenging. One way around a reluctant eater is the smoothie. Smoothies can pack an enormous nutritional punch, are easy to make, and are simple for kids to grab and go.

Diet-Blog has the basics on smoothie-making for beginners, as well as a few easy recipes. Once you get the hang of making smoothies, it's easy to play around with flavor and ingredients. You might even be able to turn a tween or teen on to the process, and before you know it, they'll be whipping up their own smoothies!

If cleaning a blender scares you off of smoothies, consider a product like the Shake and Take blender, which allows smoothie-lovers to mix up a single serving smoothie in a grab-and-go cup with straw and lid.
