"Chew or Die is a free iOS app that encourages people to try new healthy foods. The free app contains a series of healthy food challenges. The challenges include things like removing bread and potato-based starches with rice, trying a new vegetable, removing meat from your diet for a week, and sneaking more fiber into your diet. When you try a challenge take a picture of the food that you try and upload it to Chew or Die to challenge your friends to match your healthy choice"
