Why it works
- Alpha-gal syndrome: Built on fresh white fish and olive oil, completely free from mammal meat, stocks, or dairy.
- Kid (4–12): Mild Mediterranean seasoning on tender roasted fish with soft zucchini and fluffy rice.
Alpha-gal check: watch for beef, pork, lamb, venison, gelatin, lard, beef stock and, for some people, dairy. Gluten gives food ideas, not medical advice: always check labels for allergens and cross-contact.
