What Are NutriCircles?: "NutriCircles were developed at the University of Texas, Austin by Donald R. Davis in collaboration with Roger J. Williams for his book, The Wonderful World Within You (1977, 1998). They show the nutritional quality of foods in a diagram that is far easier to grasp than a long list of numbers. They illustrate how Nature helps us get the nutrients we need, if we cooperate with her in our food choices. Similarly, they help us understand the value of limiting certain man-made foods that unfortunately dominate most Western diets.
NutriCircles are bar graphs bent into a circle so that the bars are like the petals on a flower. Each bar represents one nutrient in a food, and its length shows the amount of that nutrient. The amounts are expressed in amounts per calorie (known as nutrient density). This method shows the basic quality of a food, which does not depend on serving size."
