Of all the fresh products in the supermarket, grapefruits are all too often overlooked, thanks to their reputation for being slightly bitter. However, the health benefits of these citrus fruits outweigh the disadvantages, making grapefruit juice an excellent addition to a healthy diet. Make sure you make the fruit juice yourself to get all the vitamins and nutrients and none of the unhealthy sugars that come from the variety bought in the store.
