Clue to grapefruit drug reaction

Scientists say they have the best evidence to date pinpointing the substance in grapefruit that can interact dangerously with some drugs.

Grapefruit is known to increase the rate at which some drugs - including cholesterol and blood pressure medications - enter the blood stream.

It was thought the flavonoids that make grapefruit taste bitter were to blame.

But a US study in the American Journal of Clinical Nutrition suggests other chemicals - furanocoumarins - are key.
