Yes, if you are allergic to it ...

Maize flour-induced rhinitis
Persistent rhinitis due to eating maize (e.g. cornflour, corn-meal, corn-flakes etc.) is described in a 50-year-old patient. Fifteen years after the onset of the rhinitis, symptoms and typical reactions of food allergy to maize flour occurred: abdominal cramp-like pain and diarrhoea, and urticaria, following ingestion of polenta (cornmeal cooked in water and salt). Rhinitis resolved after stopping maize flour ingestion. The skin test to maize was strongly positive and so was the maize allergy blood test.
