Ube & Taro?

As we know, regular potato (NOT sweet potato) tends to negatively affect most HS-sufferers. Unforutnately, I suspect that ube & taro aren't good either because they're BOTH starchy root vegetables. It's a real shame because I LOVE taro & ube smoothies, even though I have them make it w/ non-dairy almond or coconut milk.

Have you guys noticed how ube & taro affect you?
