I don’t quite follow. Peanuts and macadamia nuts have the same amount of sugar per one cup serving, so on what basis are you avoiding peanuts?
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.
