About foodindex.co

foodindex.co answers one kind of question well: “Is this product vegan? Keto? Gluten-free?” — for real, branded grocery products, all diets on one page, from real ingredient data.

Every verdict shows its work. A “no” names the deciding ingredient. A computed check (keto, low-carb, low-sugar) shows the actual number against the threshold it was compared to — and says plainly whether that threshold is a real regulation (like the FDA’s high-protein definition) or our own disclosed methodology (like our ≤5g net carbs per serving keto bar; no official keto standard exists anywhere). When the data can’t support an answer, we say “can’t determine — worth a quick check against the label before you buy” instead of guessing.

Product data comes from Open Food Facts (ODbL) — see attribution. Data can be incomplete or out of date; always verify against the physical label, especially for allergies.
