Smoothie

A smoothie's histamine impact depends almost entirely on what's in it — some combinations are fine, others stack multiple triggers.

• Ingredient stacking — common smoothie ingredients like strawberries, pineapple, and citrus juice are well-established or strongly suspected histamine liberators; banana also appears on some intolerance lists due to its biogenic amine content, though its classification as a histamine liberator is less consistent than citrus or strawberries; blending several higher-risk ingredients together can multiply the potential effect

• Better base choices — mango, blueberries, pear, and coconut milk tend to be lower-histamine options for building a smoother smoothie

Building your smoothie around lower-histamine fruits and a neutral base like oat milk or water gives you more control over what you're taking in.
