Sweetened frozen blueberries have 85 kcal per 100 g. The added sweetening nearly doubles the sugar compared to fresh (19.7 vs 10 g). Check the label — sugar content varies widely between brands.
How should I track Blueberries, frozen, sweetened?
When tracking Blueberries, frozen, sweetened, weigh the edible portion — after peeling, coring, or removing seeds. The part you throw away does not count, but it can make up 20–40% of the total weight depending on the fruit. A systematic review (Whitton et al., Adv Nutr 2022) found that fruits are among the most commonly misestimated food groups. One more thing to watch: fresh and dried versions have very different calorie density. A handful of dried fruit can have the same calories as a whole bowl of fresh — always double-check which form you are logging.
