Oca & Jerusalem Artichokes

[noj89]

Hello all, my name is Jon and im a very long time lurker

I tryed the search on this topic but it doesnt appear to be working at the moment, im very sure this question has been asked before

Ive getting sucked into everyones excitement about growing Oca and it makes me want to have a go aswell, but i have some doubts, due to my expericences with Jerusalem Artichokes (JA),

As far as i can work out both these plants have a sugar known as inulin, which im led to beleive is the reason why JA makes me so "windy" after eating them, i was wondeirng if Oca has a similar effect on the body?
Usually these things wouldnt worry me but we got some JA last year and each of our 7 tubers has produced about 3/4's of a large plastic trug in return, This is obivoiusly way to many and as much as i like them, the pain (yes real pain, thats another story from mistakenly eating a large amount one night has sort of put us off them for the moment,

So as much as Oca sounds amazing and something id like to try,can anyone shed anylight on this ?

Many thanks

Jon

Oca has never given me any wind, honest They taste like potato with no ill-effects.

I know what you mean about Jerusalem Artichokes - only eat them at the weekend now!!

I too fancy the idea of oca and hadn't thought of this? Jerusalems don't have this impact on me, but they do on my OH! So this has dampened my enthusiasm for them abit Have read that they are a little pricey too? May be large price to pay for for windy consequences?

I don't think Oca contain inulin, although they do contain Oxalic acid, which is what gives them the lemony-zing. I've not had any 'windy' problem eating them and I don't know anyone who has.

I think they are worth trying, easy to grow and the tubers are v. pretty

Here's a nice blog mentioning Oca and JAs: Growing Unusual Edibles

and a bit more info on growing and eating: http://ecofarm.ie/oca/

I can't find any mention of oca containing inulin though. Onions and garlic are apparently high in it: http://en.wikipedia.org/wiki/Inulin
