Too mainstream?

Peanuts are composed mostly of polyunsaturated fat (mostly omega 6 and very low omega 3) and macademia nuts are mostly monounsaturated fats. If you care about your omega 6 to omega 3 ratio in the diet then macademia nuts are probably better for you.

I am not redefining Candy, I am using non food definition of candy to make a point. "Something that is pleasing or pleasurable, usually in a superficial way"

Peanuts are frequently used as part of a wide range of sweets for texture. But, they are also sweet enough to not be out of place and in no way make them heathy by proxy. Similarly, eating a full serving of penuts regularly is generally a bad idea.
