Toots & Trots / Does it matter?
Jerusalem artichoke or peeled potato — does it matter?
They look like cousins on the bench and they behave nothing alike. A peeled, boiled potato is mostly gentle starch and one of the lowest scorers in the catalogue. The Jerusalem artichoke stores its energy as inulin instead, which passes through undigested and ferments quickly — it's the reason for its other nickname. If you've seen it suggested as a swap for potato, this is the gap you'd be taking on.
Scores use a standard reference serving via the GASP model. Individual tolerance varies.
Yes — mainly because of gas.
If wind and bloating is a problem for you, Potato (peeled) — boiled & drained is worth trying. If you're tolerating Jerusalem artichoke — roasted (low oil) without issues, the difference may not show up for you personally.
