A scientific team at the Friedman School of Nutrition Science and Policy at Tufts has developed a new tool to help consumers, food companies, restaurants, and cafeterias choose and produce healthier foods and officials to make sound public nutrition policy.
Food Compass is a new nutrient profiling system, developed over three years, that incorporates cutting-edge science on how different characteristics of foods positively or negatively impact health. Important novel features of the system, reported Oct. 14 in Nature Food, include:
“Once you get beyond ‘eat your veggies, avoid soda,’ the public is pretty confused about how to identify healthier choices in the grocery store, cafeteria, and restaurant,” said the study’s lead and corresponding author, Dariush Mozaffarian, dean of the Friedman School. “Consumers, policymakers, and even industry are looking for simple tools to guide everyone toward healthier choices.”
The new Food Compass system was developed and then tested using a detailed national database of 8,032 foods and beverages consumed by Americans. It scores 54 different characteristics across nine domains representing different health-relevant aspects of foods, drinks, and mixed meals, providing for one of the most comprehensive nutrient profiling systems in the world. The characteristics and domains were selected based on nutritional attributes linked to major chronic diseases such as obesity, diabetes, cardiovascular problems, and cancer, as well as to risk of undernutrition, especially for mothers, young children, and the elderly.
Food Compass was designed so that additional attributes and scoring could evolve based on future evidence in such areas as gastrointestinal health, immune function, brain health, bone health, and physical and mental performance; as well as considerations of sustainability.
Potential uses of Food Compass include:
Each food, beverage, or mixed dish receives a final Food Compass score ranging from 1 (least healthy) to 100 (most healthy). The researchers identified 70 or more as a reasonable score for foods or beverages that should be encouraged. Foods and beverages scoring 31-69 should be consumed in moderation. Anything scoring 30 or lower should be consumed minimally.
Across major food categories, the average Food Compass score was 43.2.
Food Compass is the first major nutrient profiling system to use consistent scoring across diverse food groups, which is especially important for mixed dishes. For example, in the case of pizza, many other systems have separate scoring algorithms for the wheat, meat, and cheese, but not the finished product itself. Consistent scoring of diverse items can also be helpful in assessing and comparing combinations of food and beverages that could be sold and consumed together, such as an entire shopping basket, a person’s daily diet pattern, or a portfolio of foods sold by a particular company.
“With its publicly available scoring algorithm, Food Compass can provide a nuanced approach to promoting healthy food choices–helping guide consumer behavior, nutrition policy, scientific research, food industry practices, and socially based investment decisions,” said last author Renata Micha, who did this work as a faculty member at the Friedman School and is now at the University of Thessaly.
