Have you ever noticed your autoimmune symptoms flare after certain foods… or even after a 🍷 ?
Foods like aged cheese, fermented foods, processed meats (and even leftovers) are naturally high in histamine.
And for some people, especially those with autoimmune conditions, they can trigger symptoms like:
👉 Rosacea flares
👉 Rashes or hives
👉 Flushing
👉 Headaches
👉 Joint pain
👉 Fatigue
👉 Even worsening PMS symptoms
Histamine is a natural immune chemical involved in inflammation, gut health, and immune defense.
But when you have an autoimmune condition, your immune system is already overactive and primed to react.
High-histamine foods don’t cause autoimmune disease, but they can add fuel to an already inflamed fire, amplifying symptoms and worsening flares.
There’s also a gut connection.
Histamine is normally broken down in the gut by an enzyme called DAO (diamine oxidase).
But when you have issues like leaky gut, dysbiosis, or SIBO, your body may not produce enough DAO to break down histamine properly, allowing levels to build up.
Some people may also have Mast Cell Activation Syndrome (MCAS), in which immune cells release excess histamine, further intensifying symptoms.
See the slides for testing options and supportive strategies to help reduce your histamine load.❤️
