Cranberry juice has 46 kcal and 12.1 g sugar per 100 g. A Cochrane review of 50 RCTs (Williams et al., 2023) found cranberry products reduced UTI risk by 30%. Most retail "cranberry juice" is heavily sweetened — check the label for 100% juice if that's what you want.
How should I track Cranberry juice, unsweetened?
Liquid calories from Cranberry juice, unsweetened are easy to overlook because drinks do not trigger the same fullness signals as solid food. A meta-analysis (Wehling & Lusher, Am J Clin Nutr 2021) confirmed that people underreport beverage intake more than solid food. Most people pour 30–50% more than the label serving size without realizing it. Use a kitchen scale to weigh your glass or bottle once — you will know your exact pour going forward. This one calibration step can save you from hundreds of untracked calories per week.
