Batata seems to be either potato or yam, so yes we do,
Yuca we have, had some today ^_^ (Yuca is a great carb source and it has incredible low GI, however it contains a large amount of carbs, so I recommend to have about 3 to 4oz of it)
Yautia I think we have (called nampi I think) (Very good, high in carbs as well)
Casaba we do not have
Remolacha is yummy and we do have, it's the same as beats(Not too much because of the sugar, however is good to incorporate it occasionally)
Always try new things, but start with a small amount and see how your body reacts. One of my favorite is Batata and is very high in carbs, but my body loves it.
