Check out this resource page from the Dairy Council of California about the balance of nutrition and physical activity. This resource can be a great starting point for engaging children in conversations about their health, positive relationships with food, and ideas for trying new foods.
A main feature of this handout is asking questions of the person reading it to determine how much calcium may be necessary in their diet. It also includes information about incorporating more calcium into their diet. While this resource is mainly targeted to kids (who need more calcium at young ages for bone development), it can be helpful for people of any age.
