Ingredient notes

What to know about spinach

Spinach is genuinely nutritious and strongly anti-inflammatory, but it is also one of the highest-oxalate foods on the plate and grades high in histamine and salicylates. That combination is why a daily green smoothie or a big spinach salad can raise kidney-stone worries, itching or headaches even though the leaf itself is a nutrient powerhouse.

Watch for

  • Very high in oxalate, the single biggest reason spinach is limited on kidney-stone (calcium oxalate) diets
  • High in histamine and a moderate liberator, so it can drive itching, flushing or headaches in histamine intolerance
  • High in salicylates and a high-nickel food, extra triggers if you react to either
  • Often poorly tolerated in SIBO even though it is not especially high in the usual FODMAPs
