About

Find the foods that work for your body, in one list matched to everything you react to. Seven main triggers across 500+ whole foods, with levels based on published research: Histamine, FODMAPs, Lactose, Gluten, Salicylates, Oxalates and Sulfur. HOW IT WORKS • Set your triggers and decide how strict to be with each one: avoid, limit, watch or eat freely. • Know which chemicals are in whole foods and which of them work for you. • See iron, magnesium and 20+ nutrients in the foods you tolerate. • Match any food to how your body really reacts. • Look back on how your food list changed each month. Free to download and use. Rio is a lifestyle and educational app, not a medical device. It doesn't diagnose, treat, cure, or prevent any illness, and it's never a substitute for professional medical advice. If you suspect a food intolerance or plan major changes to your diet, talk to a qualified healthcare professional first.
