"Is this food high in histamine?" If you ask yourself that question before every meal, this app was built for you. Look it up in the food list, or scan it with your camera.
Histamine Food List is the most complete histamine food reference on the App Store: over 1,000 foods rated by histamine level with detailed descriptions, mechanism tags, and peer-reviewed citations. Now you can also scan any food with your camera to check it instantly.
SCAN ANY FOOD WITH YOUR CAMERA
Not sure if a food is safe? Point your camera at a meal, a single ingredient, or a packaged product and get its histamine level in seconds. The scanner reads plated dishes, identifies whole foods, and looks up barcodes, then gives you a clear Low, Moderate, or High rating with an explanation. Every scan is saved to your history with its photo. Your first 3 scans are free.
HIGH HISTAMINE FOODS: KNOW WHAT TO AVOID
Every food is rated Low, Moderate, or High histamine so you can see at a glance which foods are safe and which are trigger foods to avoid. Each entry includes:
- Histamine level rating
- Description explaining why the food affects histamine intolerance
- Mechanism tags: DAO Blocker, Histamine Liberator, Dairy, Gluten
- Peer-reviewed citations from published research
LOW HISTAMINE DIET: BROWSE BY CATEGORY OR LEVEL
Browse low histamine foods by category: fruits, vegetables, proteins, fish and seafood, grains, dairy, beverages, nuts, legumes, condiments, and more. Or switch to the Level view and search across all 1,000+ foods at once.
Filter by histamine level to see only Low, only Moderate, or only High histamine foods. Search is instant across every category.
MEAL IDEAS AND GROCERY LIST
Browse 50 curated low histamine meal ideas across breakfast, lunch, dinner, and snacks. Each meal shows its full ingredient list with quantities. Add ingredients to your built-in grocery list with one tap, check them off while shopping, and clear completed items.
HISTAMINE INTOLERANCE REFERENCE
Whether you're newly diagnosed with histamine intolerance, managing mast cell activation syndrome (MCAS), dealing with DAO enzyme deficiency, or maintaining an elimination diet, this is the histamine food reference you've been looking for.
Common symptoms of histamine intolerance include bloating, migraine, skin reactions, hives, digestive issues, and nausea. If you suspect a food sensitivity, knowing which foods are high histamine, which are histamine liberators, and which block DAO is the first step.
ANTIHISTAMINE FOODS AND SAFE FOODS
Not sure which foods fight histamine and which make it worse? The database covers antihistamine foods, low histamine safe foods, and high histamine trigger foods across every food category. Look up any food in seconds, or scan it.

Managing histamine intolerance is hard enough. Your tools shouldn't make it harder.
