A. Jerusalem Artichokes majorly contains a starch component-inulin. This inulin is a non-digestible starch component, hence is not digested by the digestive tract of human bodies. Also, this can be a problem as most people are intolerant to inulin. If the upper limit of consumption exceeds, this inulin will not be digested, thus leading to gas formation. Thus limiting the consumption of Jerusalem Artichokes will not make you gassy.
