Wheat allergen

Back in VPOA Davey mentioned poly phoryia ( sp)— a condition of a wheat allergen that affects the skin. Does he still have this?

I know there’s the track Porphyria on BSITS but i thought it was a kind of allergy to sunlight, no idea about the wheat. I though a wheat allergy was called Celiac’s?

Well on Cereal Wars he sings And Always Stay Away from Wheat
