Hi David, There are a few "Available Carbohydrate" tagnames which are fairly explicit, noting the components, and differentiating "by summation" vs "by difference" and "by weight" vs "as monosaccharide equivalents". Attached are two papers, old but likely still relevant, on this issue. Maybe not highly relevant to you, but they may be to people who have not appreciated the complexity of what we simply call carbohydrate. Burlingame, B.A. (1998). Proximate methods and modes of expression: variability as a harmonization issue. *Proceedings of the 21st National Nutrient Databank Conference* (1996, Baton Rouge), 122-127. Monro, J.A.; Burlingame, B.A. (1996). Carbohydrates and related food components: INFOODS tagnames, meanings and uses. *Journal of Food Composition and Analysis*, *9*, 100-118.
