Help a child choose healthy food and show him how it can benefit his body and encourage him to eat healthy food. Plus, in the long run, when that child becomes an adult, he or she will know what's good for his or her body and will make healthy choices about food. For me being Mexican, there is so much delicious food; I've learned that I can have this food but also that I need to make sure I eat healthy and know that I'm taking care of my body. When I was a freshman in high school I remember taking a class called Health. In those lessons I learned a lot about how our body works to break down food, but I demonstrated that our body is not always able to break down the food we eat.
