Talk:Prune juice

Nutritional value per 1 cup
This is very cool that everyone in the US knows how many grams one cup contains. (Or don't they?) But for other people this may become a s mystery. For example, my teacup is around 0.5 liter, my coffee cup is something like 180 ml. The cups my wife uses are of different size that mine. Would it be possible to specify the volume of the "cup" used as unit here? Xpoback (talk) 21:17, 19 January 2023 (UTC)


 * We have an article entitled Cup (unit) explaining the US vs. metric vs. various international differences, which unfortunately are not clarifying when assessing nutritional values in a food or beverage. The standard for nutrient comparisons between foods or beverages is 100 g (or 100 ml), which is the unit used by the USDA for its nutrient database - values for prune juice are here where one can select the unit desired for nutrients from the "Portion" pick list, including 256 g = 1 "cup", a confusing value given the Cup (unit) article explanations of cup volume. Some differences for beverages would exist in the amount of sediment, which might be relatively high for prune juice. With this revision, I changed the presentation of the nutrition information to a standard amount of 100 g and added a section to the article. Zefr (talk) 22:36, 19 January 2023 (UTC)
