Overview
About Egg
Is egg a trigger food?
On food chemistry it is one of the cleanest things on the plate: graded clear for histamine, histamine liberation, salicylates, tyramine, lactose, gluten, nickel and free glutamates, and clean on FODMAPs, so a plain egg is rarely why a sensitive gut complains. The reason egg still appears on almost every elimination list is immune rather than chemical. Egg is a top labelled allergen, it grades as incompatible with an eosinophilic esophagitis (EoE) elimination diet, and the proteins people actually react to (ovomucoid and ovalbumin) sit mostly in the white. Our data grades white and yolk identically, so if you are separating them, keep treating both as egg until an allergist says otherwise.

How Egg scores
Watch for
What trips people up
- Graded incompatible with an EoE elimination diet: egg is one of the six foods pulled in the six-food elimination protocol, along with milk, wheat, soy, nuts and fish
- The major egg allergens (ovomucoid, ovalbumin) are concentrated in the white, but the grades treat white and yolk the same, so a yolk-only trial is an allergist decision rather than a kitchen experiment
- Baked egg is a different exposure from scrambled. Long baking inside a wheat batter, as in a muffin, is tolerated by many egg-allergic children while a soft-cooked egg is not. Only ever test that under medical supervision.
- Hidden egg turns up in mayonnaise, meringue, the egg wash on bread, fresh pasta, nougat and many ice creams, and hides on labels as albumin, globulin, lysozyme or lecithin
- Graded borderline for lectins and pro-inflammatory on an inflammation-focused diet, which is a diet-pattern note rather than a sensitivity trigger

FAQ
Common questions about Egg
Is egg high in histamine?
No. Egg grades clean for histamine content and is not graded as a histamine liberator, so plain egg is usually fine on a low-histamine diet. If eggs upset you, look at the company they keep: the aged cheese in the omelette, the leftover cooked egg that sat in the fridge for days, or a genuine egg allergy, none of which are histamine problems with the egg itself.
Why can some children with egg allergy eat cake but not scrambled eggs?
Sustained baking inside a wheat matrix changes the shape of several egg proteins and traps others in the crumb, so a muffin or sponge presents far less recognisable allergen than a lightly cooked egg. A large share of egg-allergic children tolerate baked egg while still reacting to soft-cooked egg, and regular baked-egg eating is often part of outgrowing the allergy. Ovomucoid is the stubborn one that survives heat, which is why some children react to both. This is an allergist-supervised challenge, never a home test.
Is it the egg white or the yolk that causes an allergy?
Overwhelmingly the white. Ovomucoid, ovalbumin and ovotransferrin all live there, which is why egg-allergic people react more to whites and why some tolerate yolk once separation is clean. In practice a home-separated yolk always carries a little white with it, and our grading gives white and yolk the same allergen rating for exactly that reason.
Are eggs low FODMAP?
Yes, in practical terms. Plain eggs carry no fructans, lactose, polyols or excess fructose and grade clean overall, so they are a standard protein on a low-FODMAP plan. If eggs seem to trigger IBS symptoms, the usual culprits are the onion, garlic, butter or milk they were cooked with rather than the egg.
