Why oxalates food checker matters
Oxalates are compounds found in many plant foods that can bind with calcium to form crystals. High oxalate intake may contribute to kidney stones in susceptible individuals and can cause other symptoms in those with oxalate sensitivity.
- Stay well-hydrated to help prevent oxalate crystal formation
- Pair high-oxalate foods with calcium-rich foods to bind oxalates
- Cooking and boiling can reduce oxalate content in some foods

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
