In today's world there are so many options in food. If it's confusing for us adults, imagine how overwhelming for kids. Teaching kids and young adults healthy options and habits sets the stage for a healthy lifestyle later on. We all indulge and love something sweet or something fried. It's not about eliminating foods, but learning the give-and-take of making healthy choices. This is a learned behavior and doesn't happen overnight. But learning how to keep healthy snacks on-hand and nutritious foods available is a great framework to begin with.
Make food fun! Try cooking classes for your kids or for you AND your kids. When something is fun and interesting you're more apt to continue. ESPECIALLY when the immediate gratification is tasty! Health is an investments, so spend wisely. Eating nutritiously and learning healthy habits now beats treating illness later.
