It’s usually the size of several oranges or a melon, depending on the variety. Unripe fruit are green and turn either a light, green yellow, a mellow yellow or pink when ripe. The rind is usually thinner than in oranges and relatively smooth. A white, spongy pith or albedo is located in between the rind and the pulp. The pulp is segmented, like in orange and may or may not contain seeds. Depending on the variety, grapefruit pulp may vary in color from a light yellow or white to and pink to deeper red hues.

Most grapefruit varieties are now seedless, although not all. Why am I telling you this? Because grapefruit seeds extract is believed to have potent antiviral and antimicrobial properties. Although the mechanism has not been fully understood yet, it appears that grapefruit seeds extract stimulates the immune system, making it respond better and quicker to bacterial and viral infections. Normally, one regular-sized grapefruit can have up to a few dozen small, white seeds, similar to apple pips.

Grapefruit seeds, pulp (without juice) and pith are all crushed and mixed together alongside glycerin and other preservatives to form grapefruit seeds extract. However, studies suggest that the antimicrobial properties of the seeds extract are a result of the addition of special preservatives that enhance the action of the antimicrobial compounds naturally present in the seeds.

The fruit is a great mix of vitamins, minerals and phytochemicals with varied and beneficial health effects. Pink and red grapefruit contains lycopene, a bright red pigment also found in watermelons, tomatoes, carrots, papaya and gac fruit (see benefits of gac fruit). Lycopene is an antioxidant that combats free radical damage, especially from UVA/UVB radiation. Studies suggest it may also exert a preventive action against prostate cancer and potentially reduce risks of stomach cancer.
