Q. My husband cannot eat grapefruit due to his medication. Is the Cara cara orange related? I bought some to try (our daughter’s name is Cara!) but they resemble pink grapefruit, so I wonder if he should avoid them also.
A. Furanocoumarin compounds are those found in grapefruit that interfere with some medications. Although Cara Cara navel oranges may appear similar to grapefruit, due to coloring, current literature does not report furanocoumarins being found in Cara Cara navel oranges.
