While low in calories, grapefruit contains a whole host of nutrients. In particular, they're a good source of vitamin A, which is important for supporting the immune system and keeping the eyes and skin healthy, folate, which is key for a baby's development during pregnancy, and vitamin C, helping to maintain healthy skin.
Grapefruit also contains some magnesium, potassium and calcium.
My friend said he hated grapefruit with a passion.
I asked him if he also hates passion fruit with a grape.
