How Much Fat is Hidden in Your Favorite Foods? BioEd Online (PDF) - See page 6 of this informational student booklet for a simple hands-on activity in which students investigate the relative amounts of fat in different products. Compare similar products, such as white and wheat bread, sugar free and regular cookies, etc. Relate results to the information on the food labels. The booklet contains other fun, useful information and activities related to food labels and nutrition.
