Sensitivity notes
Why dairy proteins food checker matters
Dairy proteins (casein and whey) can cause reactions in people with milk protein allergy or intolerance. This is different from lactose intolerance and can cause both digestive and systemic symptoms.
- Dairy protein allergy requires complete dairy avoidance
- Casein and whey are the main proteins to avoid
- 'Non-dairy' products may still contain casein
- Ghee may be tolerated as proteins are removed
- This is different from lactose intolerance - treatment differs

What to know about rye
Rye is a cereal grain in its own right, sold as rye berries, rye groats, cracked rye and rye flakes, and cooked like a chewy, nutty rice. It is also one of the highest-fructan foods anywhere in the grain aisle. Our data grades rye fructans E and gluten E, so it carries two unrelated problems at once: the fructan FODMAP that drives bloating, wind and cramping in IBS, and the gluten protein secalin, which rules rye out completely in coeliac disease. Lectins are graded E as well, with oxalate and nickel sitting borderline at C. The other side of rye is why Northern and Eastern European kitchens built entire cuisines on it: no common grain is richer in viscous soluble fibre, which is what makes a bowl of cooked rye berries so unusually filling. Rye is clean on histamine, salicylates, sulfites, glutamates and tyramine, so if rye reliably sets you off, the fructans or the gluten are almost certainly why.
Watch for
- Fructans graded E, the top of the scale.Rye is more fructan-dense than wheat, and the levels are highest in the outer layers of the kernel, so whole rye berries are if anything a bigger fructan dose than sifted rye flour.
- Contains gluten.Rye sits with wheat and barley in the coeliac triad, and no amount of soaking, sprouting or long slow cooking makes rye berries safe in coeliac disease.
- Fructans are water soluble, so boiling rye berries in a generous pot of water and draining it away leaches some out.It is a genuine reduction, not a rescue, and a normal serving stays high FODMAP.
- Lectins graded E.A hard boil breaks down most cereal lectins, but rye still lands at the high end if you are tracking lectin load specifically.
- Borderline on oxalate (C) and nickel (C).Whole grains are a quiet daily background source of both, which matters far more if rye is your everyday breakfast grain than if it is an occasional side dish.
