Are fortified juices helpful?
Could juices protect against specific diseases?
"Historically, fruit and vegetable juices have been tied to a number of specific health claims," Ritz says. "For example, consider the long-standing association between cranberry juice and urinary tract health. Although data is limited, daily consumption of cranberry juice does appear to help prevent recurrent urinary tract infections in some women." Studies also suggest that pomegranate juice may help lower total cholesterol and reduce systolic blood pressure.
Must I give up juice if I'm taking a prescription medication to lower my cholesterol?
"Grapefruit juice can interfere with the metabolism of a number of prescription drugs, including certain cholesterol-lowering statins, antidepressants, and even Viagra," Ritz says. Grapefruit contains a natural substance that inhibits the liver's ability to metabolize (break down so the body can utilize) certain drugs. That can result in increased levels of the drug in the body, and with that increase, an elevated risk of harmful side effects.
Also, cranberry juice may interfere with warfarin (Coumadin), a blood-thinning medication. Talk to your physician or pharmacist about the potential for interactions between any medication you're taking and the juices you drink.
