Yes, cauliflower is low histamine. It’s one of the many low histamine vegetables you should consider adding to your diet if you’ve been experiencing any symptoms of histamine intolerance. Cruciferous vegetables like cauliflower, kale, and broccoli are highly antioxidant, and the histamine content of cauliflower is very low. It’s also just generally quite good for you overall, rich in vitamin K, choline, folate, and fiber. Both fresh and frozen cauliflower are equally good for you, though keep in mind that it’s always better to buy organic.
