Many people aim to start the year off with healthier food choices. But how do you choose between seemingly similar foods, snacks or beverages? How does a bagel with cream cheese compare to toast topped with avocado, for instance? Or a protein-based shake compared to a smoothie packed with fruits? Or two chicken dishes, prepared in different ways?

As nutrition scientists who have spent our entire careers studying how different foods influence health, our team at Tufts University has created a new food rating system, the Food Compass, that could help consumers and others make informed choices about these kinds of questions.

Food rating systems explained

Many such systems exist and are widely used around the globe. Each one combines facts about different nutritional aspects of foods to provide an overall measure of healthfulness, which can be communicated to consumers through package labels or shelf tags. They can also be used to help guide product reformulations or socially conscious investment goals for investors.
