A Sour Note
A daily dose of grapefruit juice may not be a good idea
(HealthDayNews) -- If you're a woman, you could actually do yourself harm by drinking grapefruit juice on a daily basis.
A long-term study of 80,000 female nurses conducted by the Harvard Medical School and Brigham and Women's Hospital in Boston found that the possibility of kidney stones was boosted by 44 percent for those who drank an 8-ounce glass of the juice each day.
On the other hand, researchers found, a cup of tea decreases a woman's chances of getting kidney stones by 8 percent. Coffee cuts it by 9 percent and moderate consumption of wine by 20 percent.
But grapefruit juice does have its proponents. A newly identified compound in it named bergamottin boosts the potency of a wide variety of drugs, according to joint research by the University of Michigan and the Parke-Davis Pharmaceutical Company. In the test tube, bergamottin incapacitates an enzyme that breaks down drugs, hence greatly increasing the amount of the drug available to the body.
