Grapefruit juice and cancer

Grapefruit juice could help fight cancer.

A glass of it every day could help boost the effect of an anti-cancer drug in some patients.

A study finds eight ounces of grapefruit juice helps slow the body’s metabolism of a drug called sirolimus, which treats some types of cancer.

The juice would allow patients to take a lower dose of the drug, helping them avoid it’s side effects.
