Olivani is, as Rachel said, there's also a new one out callied Olivite, you can get it at Pak n Save, New World etc but not at Woolworths/Countdown/Foodtown...I prefer it to Olivani, and it's half the price (except we shop at Woolworths so I never get it

). There's another brand of ice cream called Lite Licks which is dairy free - doesn't taste so much of soy as So Good, and comes in Berry, Hokey Pokey, Vanilla and Chocolate Ripple (which is my fave).
Complan is dairy based, which will be why she can't tolerate it (most shake type drinks are dairy based).
