What to know about kale
Kale earns its superfood reputation on the trigger data: it is strongly anti-inflammatory, low in histamine, and, unlike spinach, genuinely low in oxalate, so it is a rare leafy green that oxalate-sensitive and kidney-stone-prone people can usually enjoy. The caveats are real but specific. It is a cruciferous vegetable that ferments heavily in the gut and so grades poorly for SIBO; it is moderate FODMAP by the plateful; and it carries a moderate amount of nickel that matters if you have systemic nickel allergy.
Watch for
- Low in oxalate, which sets it apart from spinach, chard and beet greens: a good swap if oxalate or kidney stones are your issue
- Cruciferous and highly fermentable, so it grades poorly for SIBO and can cause gas and bloating in larger raw servings; light cooking helps
- Moderate FODMAP by volume, so a small side is fine on low-FODMAP but a big raw bowl may not be
- Contains a moderate amount of nickel, relevant if you have systemic nickel allergy and are combining several nickel-rich foods
