This infographic illustrates what a portion of various foods (both healthy and unhealthy) looks like using the thumb and the palm(s) of your hand as a guide. The chart is simple and easy to remember and very useful, especially when you are eating out. Before digging into that meal, take a few minutes to study the amount of food that is on the plate and compare it with your hand(s).
