Serving size, prep, and portion notes for corn grits
Corn grits are naturally gluten free and low FODMAP, and they grade clean on histamine, salicylates, free glutamates, nickel and sulfites, which makes them one of the calmer hot breakfasts for a reactive gut. The one trigger they genuinely flag is lectins, where grits grade high. The other soft spot is not the corn at all: it is cross contamination, because most grits are milled and shipped on lines that also handle wheat.
Watch for
High in lectins, the only food chemistry trigger grits actually flag. Lectins are heat sensitive and grits are simmered wet for a long time, so the exposure from a properly cooked pot is lower than the raw grade suggests, but quick five minute instant grits get far less of that treatment / Naturally gluten free as a grain, yet coeliacs still react to some brands. The gluten comes from shared milling, storage and transport with wheat, which is why a certified gluten free bag is the thing that changes outcomes, not switching corn variety / Moderately fermentable, so a big bowl gives gut bacteria a lot of starch to work on. Relevant if you are managing SIBO rather than plain IBS, since the FODMAP subscores themselves are clean / Borderline on the inflammatory scale and only a middling fit for a Mediterranean pattern, which is what you would expect from a degermed refined starch eaten in volume
