Pink and red grapefruit has 42 kcal and 6.9 g sugar per 100 g. The pink-red color signals plant pigments linked to health benefits. Track without extra sugar — many people sprinkle sugar on grapefruit halves.
How should I track Grapefruit, raw, pink and red, all areas?
When tracking Grapefruit, raw, pink and red, all areas, 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.
