 The suggested method for calculating dietary fiber content in foods is more accurate than the current methods used by the Codex Alimentarius Commission, CAC, and the U.S. Food and Drug Administration, FDA. The suggested method takes into account both the reference amount customarily consumed, RACC, and the energy content of the food, while the other two methods do not. This means that the suggested method ensures that the food meets the recommended daily intake of dietary fiber without exceeding the energy requirements. Additionally, the suggested method allows for the selection of foods that meet the dietary fiber requirement without exceeding the energy requirement.
