Guava nectar has 63 kcal per 100 g. Nectars contain fruit pulp blended with water and sugar — thicker than juice but still a liquid calorie source. Track as a beverage, not a fruit serving.
How should I track Guava nectar, canned, with added ascorbic acid?
When tracking Guava nectar, canned, with added ascorbic acid, 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.
