Find out the difference between serving sizes and portions sizes. Choosing nutritious foods and keeping portion sizes sensible will help keep your family at a healthy weight.

One of the best ways you can help your child live healthy and maintain a healthy weight is to teach them what an actual serving size looks like. They can use this knowledge to make healthier choices when eating at school, having snacks or even choosing from a fast food menu.
