The short answer
Start with serving-level fiber grams, sugar grams, and carbohydrate composition. That decides whether a label is readable or intentionally dense. FDA changes to the Nutrition Facts label FDA dietary fiber label guide
A product can be rich in fiber and still overdo sugar or sugar substitutes. The math is on the label, not in the product story. FDA dietary supplement labeling guide FDA changes to the Nutrition Facts label
