Frozen melon balls have 33 kcal and 31 mg sodium per 100 g. Pre-formed balls are convenient but the sodium is notably higher than fresh (1 mg). Weigh while frozen — thawing releases water.
How should I track Melon balls (frozen)?
When tracking Melon balls, 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.
