Most are confused about the basic food groups, and that is no surprise. I remember learning about them when I was in elementary school, but nothing about them in high school. Perhaps there is not enough emphasis on the basic food groups in schools. What I like to see is that this is a big topic for my daughter, who is now in kindergarten, and she is always talking about the basic food groups when I am making dinner. It would seem that she knows more about them than I do. Perhaps putting a lot of emphasis on them when children are very young is the way to go, but knowing what basic foods and groups are important should be a lifelong learning experience.
