Grapefruit is part of the citrus family and grows in clusters on the tree, like grapes – this is said to be where the name originates. Grapefruits come in a variety of colours including yellow, pink and red, and they have a variety of tastes from sweet to sour. 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.
