Why Your Body Reacts “More” — And It’s Not in Your Head
If you have MAO-A TT, your body processes serotonin, dopamine, norepinephrine — and histamines + tyramines — more slowly. This isn’t a character flaw. It’s enzyme biology.
What does this mean?
👉 Your bucket fills faster
Foods high in tyramine (aged, fermented, cured) or histamine (leftovers, alcohol, vinegars, certain fruits) stay circulating longer because MAO is one of the enzymes that helps break them down.
👉 Your threshold is lower
When the bucket fills, symptoms show up as:
  • Head pressure or “helmet sensation”
  • Anxiety or irritability that hits suddenly
  • Heart racing or feeling “wired but tired”
  • Flushing, sinus pressure, skin reactions
  • Body aches or inflammation spikes
  • Waking at 2–3am with adrenaline
  • Feeling drained the next day from the overload
👉 It’s not sensitivity — it’s accumulation. MAO-A TT doesn’t mean your body is “fragile.”
It means your clearance rate is slower, so the impact stacks.
🍷🍓 Common Tyramine & Histamine Triggers
You might recognize these patterns:
High-Histamine Foods
  • Leftovers (especially meats)
  • Fermented foods (sauerkraut, kimchi)
  • Aged cheeses
  • Alcohol, especially wine
  • Vinegars & pickled foods
  • Certain fruits: strawberries, citrus
  • Smoked or cured meats
High-Tyramine Foods
  • Aged or cured meats
  • Aged cheeses
  • Fermented soy
  • Overripe bananas, avocados
  • Nuts, seeds (when stored long-term)
  • Chocolate
When these combine with MAO-A TT… the nervous system feels it.
🔍 What This Means For Your Nervous System
Your body is not overreacting — it's reacting because the brainstem enzymes (MAO-A lives heavily there) can’t keep up with the load.
This can look like:
  • Emotional flooding
  • Feeling “too much”
  • Overwhelm from small triggers
  • Mood swings that don’t match the moment
  • Crash after eating certain foods
  • Migraines or tension headaches
  • Gut motility slowing (because histamine affects the vagus)
And most people never connect the dots.
✔️ What Helps Calm the System
These strategies help lower the load before it overwhelms you:
  • Fresh foods instead of leftovers
  • Low-histamine fruit (blueberries, apples, pears)
  • Ground meats cooked fresh
  • Cooking with lemon juice instead of vinegar
  • Taking DAO before high-histamine meals
  • Supporting methylation & antioxidants (for MAO balance)
  • Slow nervous system resets (breath work, grounding, cold/warm contrast)
The goal isn’t perfection — it’s keeping the bucket from overflowing.
💬 Final Thought
If you have MAO-A TT, your emotional and physiological responses make perfect biochemical sense. Understanding this removes shame, reduces fear, and gives you a way forward.
Your body isn’t random. It's predictable. And once you see the pattern…You can learn to work with your design instead of against it.
This is why knowing your genes can help you focus and create the habits and strategies that work best for you.
