Do I Eat This?

The companion app to the book D.I.E.T.? Do I Eat This? The book explains the reasoning. The app puts it to work in the grocery aisle: one food list, seventeen ways of seeing it — histamine, oxalates, lectins, mold, FODMAPs, hidden gluten and allergens, candida, detox support, glucuronidation, anti-inflammatory picks, bioenergetics, fiber sources, metabolism, resistant starch, polyunsaturated fat, paleo, and a Nutrient Rich index of 30 nutrients. What you get • A verdict on every one of 386 foods: which categories flag it and why, with swaps for each • Search any food — or any nutrient. Type "copper" and its best food sources come back with amounts per serving • A nutrient index that jumps you straight to the table you want — calcium to zinc, amino acids included • Mark your allergens once and every food containing them turns red everywhere in the app • Your own list: favorites, foods you avoid, and a private note on any food • Lower- and higher-histamine lists, high/moderate/low FODMAPs, oxalate flags, prebiotic foods, paleo by food group Works entirely offline. No account, no sign-in — your notes and picks stay on your phone. The book carries the full story behind every table in this app — the 2026 revision is on its way.
