This is a nice colour poster that you can use at a lesson about nutrition or just hang on the classroom wall. It shows a pyramid with several different colours - each depicting a food group: grains, vegetables, fruits, milk, meat & beans.
There are also bright and attractive pictures for the foods in each group.
This nutrition poster (The Food Pyramid Nutrition Poster) is kindly provided by the US Department of Agriculture, Food and Nutrition Service, and is also available from their website for free download.
Enjoy!
