Discovered in 1989, grapefruit has the ability to raise the effects of drugs by increasing the power of its potent compounds. It contains naringenin, bergamottin and dihydroxybergamottin, which slows down the protein isoform CYP3A4 in the intestine.

This enzyme glimmers a response within the liver which helps in producing noxious compounds more water soluble for emission from the body. Citrus pulp like grapefruit contain glucarates, compounds that may help prevent breast cancer.

The persistence and bioavailability of Limonin are potential substance which could help in the prevention of cancerous cells from reproducing.

• Delicious, grapefruits are very low in calories but rich in dietary insoluble fiber, pectin which by acting as bulk laxative helps to protect the colon mucous membrane by decreasing exposure time to toxic substances in the colon as well as binding to cancer causing chemicals in the colon.
• Pectin has also been shown to reduce blood cholesterol levels by decreasing re-absorption of cholesterol binding bile acids in the colon.
• It contains very good levels of vitamin-A and flavonoid antioxidants such as naringenin, beta carotene, xanthin and lutein. Studies suggest that these compounds have antioxidant properties and are essential for vision.
• Vitamin A also required maintaining healthy mucus membranes and skin. Consumption of natural fruits rich in vitamin-A and flavonoids helps to protect from lung and oral cavity cancers.
• Fresh fruit is very rich in potassium. Potassium in an important component of cell and body fluids, helps controlling heart rate and blood pressure.
