There are always claims over fruit or fruit drinks and their health benefits. A daily glass of grapefruit juice lets patients derive the same benefits from an anti-cancer drug as they would get from more than three times as much of the drug by itself, according to a new clinical trial. The combination could help patients avoid side effects associated with high doses of the drug and reduce the cost of the medication. Researchers at the University of Chicago Medicine study the effects that foods can have on the uptake and elimination of drugs used for cancer treatment. In a study published in August in Clinical Cancer Research, they show that eight ounces a day of grapefruit juice can slow the bodyâ€™s metabolism of a drug called sirolimus, which has been approved for transplant patients but may also help many people with cancer.
Grapefruit is an excellent source of many nutrients and phytochemicals that contribute to a healthy diet. Grapefruit is a good source of vitamin C, contains the fiber pectin, and the pink and red hues contain the beneficial antioxidant lycopene. Studies have shown grapefruit helps lower cholesterol, and there is evidence that the seeds have antioxidant properties.
