I grew some yacon in the garden last summer for the first time. The root being the part of the plant you eat, I had thought it might pass the FODMAP test. However, it was on the ‘do not eat’ list. I wanted to know why, so did a bit of searching and this is what I came up with – it seems yacon contains inulin, which is a fibre that can aid digestive health (in those without IBS and for who FODMAP diet doesn’t improve symptoms). It is often contained in fibre supplements. It can be made synthetically in labs, but also occurs naturally in yacon.
Well, I tasted the yacon anyway as I had never had it before. It was quite juicy and sweet, a bit like a cross between an apple and a carrot. The small bit I ate didn’t seem to affect me, but I left the rest for other family members to eat.
