I know that it is not recommended to drink grapefruit juice when
taking certain medicines, such as certain antidepressants, since
apparently the grapefruit juice blocks metabolism of some meds by the
liver.  However, does the same issue apply, or to the same degree, if
one simply eats grapefruit?  (And especially if one only eats a slice
of two of grapefruit at a time?)

Thanks in advance....
