Not a silly question at all...

I don't juice the rinds for orange and grapefruit, in part because once I remove the rinds I can fit the fruit whole into my juicer, which seems to give best results (more juice). I do leave as much of the inner white pith as possible.

I do juice lemons and limes with the rind as they fit in my juicer. Especially if using organic produce, it's my opinion that the rind is usually good for you - loaded with vitamins. Experiment with different produce, see how it tastes, combines together, and of course how it makes you feel :)

Fresh juice in my diet has definitely helped me detox, lose weight and improve my health. Thanks for the thread Angelic_Warrior, I'm looking for some good recipes too!
