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 collard greens

Collard greens are the answer to the question people usually arrive with: they are a sturdy cooked green that grades clean on oxalate, which spinach and chard do not. They also grade clean on histamine, salicylates, nickel and gluten. The only real notes are mild fructans from the cabbage family and the fact that the traditional pot of greens is rarely just greens.

Watch for

Mild fructan content from being a brassica, so a very large bowl of a long simmered pot can still produce gas even though the overall FODMAP grade is clean / The classic Southern preparation simmers them with smoked ham hock, bacon or salt pork, and cured smoked meat is a strong histamine and nitrite source. If a plate of greens sets you off, suspect the pork and the pot likker before the leaf / The vinegar or hot sauce splash at the table adds its own histamine and salicylate load / Collards are one of the richest vitamin K foods there is. If you take warfarin, the goal is steady intake rather than avoidance, and that is a conversation for your prescriber
