Continued Feeding of Healthy Things

Brother being dosed with healthy things continues, and tomorrow we are thinking of poking a spice that is supposed to be good for you down him.  Do you think we need to give him any sort of warning about that, or spring it on him before he can escape?  Really, it looks yummy to us, so we don't know why he would object.  And haven't the last two things we have feed him for his health worked out well so far?
