Grapefruit (star ruby)

Grapefruit trees produce the best quality fruit on sandy, relatively fertile soils.

Grapefruit is a tropical citrus fruit known for its sweet and somewhat sour taste. It's rich in nutrients, antioxidants and fiber, making it one of the healthiest citrus fruits you can eat. Research shows that it may have some powerful health benefits, including weight loss and a reduced risk of heart disease.

Grapefruit has become popular as breakfast fruit in various parts of the world, and production has expanded to most citrus-growing countries. As a source of vitamin C, the grapefruit is exceeded among common fruits only by the orange and lemon.

Most varieties are yellow when ripe. The fruit ranges from 100 to 150 mm (4 to 6 inches) in diameter, its size depending upon the variety and upon growing conditions. Its pulp is usually light yellowish, tender, and very full of juice, with a distinctive mildly acid flavour. Several varieties have pink or red pulp.
