Serving size, prep, and portion notes for lettuce
Lettuce is a safe base green, clean across nearly every trigger: low histamine, low salicylate, gluten free, and importantly low in oxalate, unlike spinach, which is very high in oxalate. That makes lettuce a reliable salad base when spinach and other leafy greens are off the table. Two small notes keep it honest: it carries a modest FODMAP load in very large volumes, and its nickel content is borderline rather than negligible.
Watch for
Low oxalate, in clear contrast to spinach, which is high oxalate: swapping spinach for lettuce is a common move on a low-oxalate diet / Moderate FODMAP only in large volumes, so a normal side salad is fine while a huge bowl can add up for a sensitive gut / Nickel sits at a borderline level, worth noting if you have a strict systemic nickel allergy but not a concern for most people
