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. Watch the video below to see the app in action.
