Good new, Bad News on Grapefruit

Good news first, then the bad news.

From the Keynoter:
"Scientific evidence is beginning to stack up in favor of long-held claims that grapefruit helps fight obesity, lower cholesterol and reduce the risk of certain kinds of cancer."

Then the bad news. From ScienceDaily.com and from a study atthe University of Rochester.
"Grapefruit juice can be dangerous for people on certain medications, nurse researchers remind doctors, nurses, and everyone who takes medicine and enjoys grapefruit juice, in a paper in the American Journal of Nursing, a journal of the American Nurses Association."

How?
"Karch, an expert on drug interactions, explains that grapefruit juice is one of the foods most likely to cause problems with drugs, because it is metabolized by the same enzyme in the liver that breaks down many drugs. The cytochrome P-450 3A4 enzyme breaks down grapefruit juice into useful components for body, just like it breaks down dozens of medications. Karch says when the system is overloaded, the grapefruit juice can “swamp” the system, keeping the liver busy and blocking it from breaking down drugs and other substances."

So if you are on medications (especially cholesterol lowering medication), be sure to ask your doctor is Grapefruit is soemthing you can eat!
