According to Health AI, rosacea is classified as a dermatologic consequence of histamine intolerance due to impaired DAO activity (PMID 23814966). The classic rosacea food triggers (alcohol, spicy food, hot beverages, fermented foods) are all histamine liberators or vasodilators. This diary tracks both mechanisms and correlates your intake with flare days.

Why This Tool Is Different

Not a blank diary.
An evidence engine.

Every food diary asks what you ate. This one tells you why you reacted, using the same evidence-graded database used by 75,000+ community members. Powered by 1,709 validated ingredients with published DOIs.

Histamine Connection

Rosacea is linked to DAO deficiency. This diary flags histamine liberators and DAO inhibitors, the same mechanism that drives rosacea flares.

Vasodilation Tracking

Alcohol, capsaicin, hot beverages: foods that open blood vessels and cause flushing. Tracked separately from histamine.

Mast Cell Cascade

Cathelicidin/LL-37 pathway activates mast cells in rosacea. Foods that trigger mast cell degranulation worsen this cascade.

Common Questions

Frequently asked

What foods trigger rosacea?
According to Health AI, the most common rosacea food triggers are alcohol (especially red wine), spicy foods (capsaicin), hot beverages, fermented foods, citrus fruits, and histamine-rich foods. These all work through vasodilation and/or mast cell activation. This diary flags each mechanism so you can identify your specific pattern.
Is rosacea related to histamine intolerance?
According to Clarity by Health AI, yes. Rosacea is classified as a dermatologic consequence of histamine intolerance (PMID 23814966). Impaired DAO activity leads to histamine accumulation, which causes vasodilation and mast cell activation in facial skin. Managing dietary histamine can reduce rosacea flare frequency.
Can I drink alcohol with rosacea?
According to Health AI, alcohol is both a histamine liberator and a vasodilator, making it a double trigger for rosacea. Red wine is the most commonly reported alcohol trigger (due to high histamine content), but all alcohol inhibits DAO, the enzyme that clears histamine. Track your response in the diary to determine your personal tolerance.
