Serving size, prep, and portion notes for walnuts
Walnuts are genuinely anti-inflammatory thanks to their plant omega-3s, but they are also very high in oxalate and high in nickel, so the same handful that is good for your heart can be a real problem if you are prone to kidney stones or have a nickel allergy. That trade-off, a strong nutrition upside sitting on top of two clear triggers, is what sets walnuts apart from a plain snack nut.
Watch for
Very high in oxalate, one of the higher-oxalate nuts, worth limiting if you are managing calcium-oxalate kidney stones / High in nickel, a common flare trigger for people with systemic nickel allergy (nut, seed and wholegrain foods tend to be nickel-rich) / A tree nut, so a top allergen and not eosinophilic-oesophagitis friendly if nuts are on your elimination list
