Jerusalem: Eating one whole red grapefruit daily, decreases blood fat levels, researchers in Israel have discovered.

The researchers from the Hebrew University of Jerusalem tested white and red grapefruit on patients who had not responded to the cholesterol-lowering group of drugs known as statins. All had undergone heart bypass surgery.

After 30 days it was found that those who had consumed red grapefruit had lowered levels of blood fats called lipids. Those who consumed white grapefruit also suffered a decrease but the effect was not as marked.
