1 Results are not guaranteed. This Calculator uses JavaScript, which we understand in some circumstances may truncate or round to produce an approximate result. One can always make the calculation by hand, using the formula found in the Dietary Reference Intakes book. We used the recommendations for adults 18+ years, table 10-24. Please advise us at Service@UNJURY.com if you discover any discrepancy in calculated result.

i Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids (Macronutrients) (2005) Food and Nutrition Board (FNB). (Chapter 10, notably starting page 682).

ii Code of Federal Regulations, Title 21, 101.9 (c)(7)(ii). The page we viewed has a red header stating: "e-CFR Data is current as of September 18, 2008"

The FDA applies this methodology to protein foods whose PDCAAS is below 20. UNJURY Protein proposes that it should be applied to all protein foods regardless of whether the PDCAAS is below 20, or 25, or 50 or 100.
