↓ Full nutritionPeople love it for its refreshing, sharp citrus punch that cuts through richness and awakens the palate. It's a versatile base for both sweet cocktails and savory marinades, deeply embedded in breakfast and brunch culture.
Its high acidity can bother those with acid reflux or sensitive stomachs. The natural sugars, while not added, can cause a quick blood sugar rise, so pairing it with protein or fat (like eggs or nuts) is wise. A significant caution: grapefruit juice can interfere with the metabolism of many common medications (e.g., statins, some blood pressure drugs). Always consult a doctor or pharmacist about interactions.
The white grapefruit is actually the original variety; the more common pink and red grapefruits were discovered later as natural mutations of the white.

Is unsweetened grapefruit juice high in sugar?
It contains about 7.7g of natural sugar per 100g, which is less than many fruit juices but still significant. A full cup (244g) has roughly 19g of sugar.
Why is it called 'white' grapefruit juice?
It's made from white or yellow-fleshed grapefruits, which are the original, less common variety. The flesh is pale yellow, not pink or red.
Can I use this in cooking if I'm watching my blood sugar?
Yes, but use it in moderation. Its acidity can tenderize meat and brighten sauces without needing much. Pair dishes containing it with a source of protein or fat to slow sugar absorption.
