🤯 The Real Reason Red Wine Gives You a Headache & Sneezing Fits (It’s NOT the Sulfites or Tannins!)
I used to be a red wine lover, but one glass would trigger instant headaches, a stuffy nose, and that weird flushed feeling. The next day was a total write-off. Sound familiar?
For years, I blamed the usual suspects: sulfites, tannins, or “cheap wine.” But after a ton of research and trial-and-error, I discovered the deeper, more common culprit: Histamines. 😮
Here is the wine-histamine double-whammy you need to know about:
1. HIGH HISTAMINE LOAD: Red wine is a fermented product, and all ferments contain bacterial byproducts, including histamines. Red wine is significantly higher in histamines than white or rosé. You’re pouring an extra dose of histamines right into your system.🍷
1. DAO Enzyme Shutdown: The alcohol in the wine simultaneously reduces your natural DAO enzyme activity. DAO is the crucial enzyme whose job is to break down and clear histamine from your body.😦
Essentially, red wine is double-trouble: You’re adding more histamine AND slowing down your body’s ability to clear it. If your body is already sensitive (histamine intolerant) or your natural DAO levels are low (which naturally declines as we age!), even one glass can cause a cascade of reactions:
😓Headaches/pressure
😷Flushing/Red face
🤧Congestion/Runny nose
❤️Rapid heartbeat or anxiety
😶🌫️Brain fog the next day
🍷 THE RED WINE RESCUE HACK:
If cutting out wine forever isn’t an option, there’s a simpler way to enjoy your glass without the side effects. We discovered a powerful DAO enzyme supplement called HistaHarmony.
✅The trick is simple: Take 1-2 capsules a few minutes before you have your glass of wine. The DAO gets to work immediately, breaking down and eliminating the excess histamines before they can upset your system. Shay and I used this hack all through our trip in Italy—drinking red wine, eating cheese, and enjoying coffee—and were completely symptom-free.
If histamine overload is your issue, don’t let a glass of wine ruin your evening (or your next day!).
