A certain variety of seeds known as glabrous canary seeds are beneficial to humans because they are bred to be gluten-free, according to the American Chemical Society. Glabrous canary seeds are a cereal bred for human consumption that can be safely consumed by those who suffer from celiac disease, thus expanding the dietary choices available to this population.
Canary seeds are typically used as bird feed and are inedible to humans due to the presence of small indigestible fibers, explains the American Chemical Society. However, scientists engineered a new variety of this grain, referred to as "hairless" seeds because they lack these fibers, rendering them digestible. The seeds are naturally gluten-free, contain a higher amount of protein than other cereals, and remain rich in nutrients even after being modified for human consumption. Glabrous canary seeds can be made into flour that is suitable for making bread, cookies, cakes and other baked goods.
Some other cereals that are gluten-free include quinoa, millet, sorghum and buckwheat, according to the American Chemical Society. At least 3 million people in the United States alone suffer from Celiac disease and so there is a demand for nutrient rich foods that can be safely consumed by those with this condition.
