Insights

Every figure below has a formula — select any heading to see it. These are properties of the ingredient, so they do not move with serving size: 14% of romaine lettuce, raw’s calories come from fat whether you weigh out RACC or bunch.

These are descriptive ratios, not nutrient content claims. A claim such as “good source of calcium” or “high protein” is evaluated per RACC serving under 21 CFR 101.54 — a different calculation, on a different basis, which this page does not make.
