Canned peaches in extra heavy syrup have 96 kcal per 100 g. The densest syrup option nearly triples fresh peach calories. Draining removes some syrup but the fruit absorbs sugar during processing.
How should I track Peach nectar, canned, with added ascorbic acid?
When tracking Peach 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.
