In the early 1980s, a enzymatic-gravimetric method was developed in which the sum of soluble and insoluble polysaccharides and lignin were measured as a unit and considered to be total dietary fibre (TDF). That method is detailed in section 45.4.07 of the AOAC International . Enzymes employed had to meet specific activity requirements and be devoid of contaminating enzymes active on dietary fibre components. The method that evolved was AOAC Official Method 985.29 ‘Total Dietary Fiber in .

The U.S. Food and Drug Administration states that eating a diet high in dietary fiber promotes healthy bowel function and that a diet that is rich in fruits, vegetables, and grain products containing dietary fiber, particularly soluble fiber, and is low in saturated fat and cholesterol may reduce the risk of heart disease.Two general types of methods have been developed for isolating and analyzing dietary fiber: enzymatic-gravimetric and enzymatic-chemical. The food components isolated vary depending on the method used. Both the enzymatic-gravimetric and enzymatic-chemical methods have undergone a number of modifications and improvements, most occurring over the last 20 .
Three methods have had sufficient collaborative testing to be generally accepted by such bodies as AOAC International and the Bureau Communautaire de Reference (BCR) of the European Community (EC) (FAO, 1998): the AOAC (2000) enzymatic, gravimetric method - Prosky (985.29); the enzymatic, chemical method of Englyst and Cummings (1988); and the .
