FORTUNE — The nation's largest food conglomerates are looking to cash in on what was once a tiny niche: the growing number of Americans avoiding gluten, a protein found in wheat, rye and barley.

Their moves are breaking gluten-free products out of the specialty health-food aisle with re-formulations of brands like General Mills' Bisquick, as well as re-branding existing rice-based products like Post's Cocoa and Fruity Pebbles as gluten-free.
