# Triggerbites > Triggerbites is an AI-powered food & symptom journal that helps people spot patterns between what they eat and how they feel. It also publishes free food-sensitivity reference data: histamine, FODMAP, salicylate, oxalate and other trigger ratings, plus diet-compatibility ratings, across 900+ ingredients. Triggerbites helps people with IBS, migraines, GERD, histamine intolerance and other food sensitivities identify their triggers. Users log meals and symptoms in plain language ("like texting a friend") and the app surfaces patterns. The free web tools below grade individual ingredients by trigger level (S = best tolerated through E = highest signal) and by diet compatibility. All ratings render as plain text on each page. ## Food sensitivity checkers - [Histamine Food Checker](https://triggerbites.com/tools/histamine-food-checker): Histamine levels across 900+ ingredients, with lower-histamine alternatives. - [Histamine Liberator Checker](https://triggerbites.com/tools/histamine-liberator-checker): Foods that may trigger histamine release even when not histamine-rich. - [Tyramine Checker](https://triggerbites.com/tools/tyramine-checker): Tyramine load across aged, cured and fermented foods. - [Caffeine Checker](https://triggerbites.com/tools/caffeine-checker): Caffeine content across beverages and foods. - [FODMAP Food Checker](https://triggerbites.com/tools/fodmap-food-checker): FODMAP load across 900+ ingredients. - [Fructans Checker](https://triggerbites.com/tools/fructans-checker): Fructan content (a FODMAP subtype) across ingredients. - [GOS Checker](https://triggerbites.com/tools/gos-checker): Galacto-oligosaccharide (GOS) content across ingredients. - [Fructose Checker](https://triggerbites.com/tools/fructose-checker): Excess-fructose ratings across ingredients. - [Polyols Checker](https://triggerbites.com/tools/polyols-checker): Polyol (sugar alcohol) content across ingredients. - [Lactose Checker](https://triggerbites.com/tools/lactose-checker): Lactose content across dairy and processed foods. - [Gluten Checker](https://triggerbites.com/tools/gluten-checker): Gluten-containing vs gluten-free status across ingredients. - [Salicylate Food Checker](https://triggerbites.com/tools/salicylate-food-checker): Salicylate levels across 900+ ingredients. - [Oxalate Food Checker](https://triggerbites.com/tools/oxalate-food-checker): Oxalate levels across 900+ ingredients. - [Nightshade Checker](https://triggerbites.com/tools/nightshade-checker): Identifies nightshade-family foods. - [Lectin Checker](https://triggerbites.com/tools/lectin-checker): Lectin content across ingredients. - [Nickel Checker](https://triggerbites.com/tools/nickel-checker): Dietary nickel levels for systemic nickel allergy. - [Sulfite Checker](https://triggerbites.com/tools/sulfite-checker): Sulfite content across foods and drinks. - [Nitrites Checker](https://triggerbites.com/tools/nitrites-checker): Nitrite/nitrate content across cured and processed foods. - [Glutamates Checker](https://triggerbites.com/tools/glutamates-checker): Free-glutamate (MSG) load across ingredients. - [Dairy Proteins Checker](https://triggerbites.com/tools/dairy-proteins-checker): Casein and whey content across foods. - [SIBO Checker](https://triggerbites.com/tools/sibo-checker): SIBO-relevant ratings across ingredients. ## Diet compatibility checkers - [Anti-Inflammatory Diet Checker](https://triggerbites.com/tools/anti-inflammatory-diet): Anti-inflammatory diet compatibility across 900+ ingredients. - [Mediterranean Diet Checker](https://triggerbites.com/tools/mediterranean-diet): Mediterranean diet compatibility across ingredients. - [DASH Diet Checker](https://triggerbites.com/tools/dash-diet): DASH diet compatibility across ingredients. - [Paleo AIP Diet Checker](https://triggerbites.com/tools/paleo-aip-diet): Paleo / Autoimmune Protocol (AIP) compatibility across ingredients. - [EoE Diet Checker](https://triggerbites.com/tools/eoe-diet): Eosinophilic esophagitis (EoE) elimination-diet compatibility. - [Vegan Diet Checker](https://triggerbites.com/tools/vegan-diet): Vegan compatibility across ingredients. - [Vegetarian Diet Checker](https://triggerbites.com/tools/vegetarian-diet): Vegetarian compatibility across ingredients. ## Reference and tools - [All tools](https://triggerbites.com/tools): Index of every checker and tool. - [Ingredient library](https://triggerbites.com/ingredients): Per-ingredient profiles spanning every trigger and diet rating. - [Ingredient lookup](https://triggerbites.com/lookup): Search any ingredient by name. - [Food Detective](https://triggerbites.com/tools/food-detective): Swipe through foods to build a personal sensitivity profile. - [Conditions](https://triggerbites.com/for): How Triggerbites helps with specific conditions (IBS, migraines, GERD and more). - [Blog](https://triggerbites.com/blog): Articles on food sensitivities, elimination diets and symptom tracking. ## Optional - [Support](https://triggerbites.com/support): Help and contact. - [Privacy policy](https://triggerbites.com/privacy) - [Terms of service](https://triggerbites.com/tos)
