It's lucky that flu season and grapefruit season overlap – in the cold winter months, the exotic-looking grapefruit is at the height of its popularity. It is particularly rich in potassium and vitamin C and is therefore the perfect immunity boost at breakfast time. A grapefruit meets 60% of your daily requirement of vitamin C. Simply cut in half, sprinkle some Frusano grain sugar on top, and enjoy!
The grapefruit is a cross between the orange (citrus × sinensis) and the pomelo (citrus maxima). It is believed that it originated around 1750 from a spontaneous cross between the two fruits in Barbados.
