Why Countries Are Color-Coding Healthy Foods at Grocery Stores
Briefly

"Nutrient profiling systems, or NPSs, support clear front-of-package labels that assess food quality based on nutrient content. In contrast, the U.S. lacks a front-of-package ranking system for food."
"Food Compass was recently developed out of Tufts University to help address this gap and shortcomings in other systems but it uses nutritional information not currently available for most foods and consumers."
"Drawing on this research, I developed Nutrient Consume Score, or NCS, which rates foods from 1 to 100 using nutritional information available for all foods and incorporates factors important for a healthy microbiome."
"Each nutrient profiling system uses different scoring algorithms, but most assign positive points to nutrients and foods that are typically underconsumed, such as fiber, fruits and vegetables."
