Graham flour

Graham flour is a type of coarse-ground flour of whole wheat named after Sylvester Graham. It is similar to conventional whole-wheat flour in that both are made from the whole grain, but graham flour is ground more coarsely. It is not sifted ("bolted") with a flour dresser after milling. A report from 1913 claimed that bread made from graham flour had a protein content of 12.1% – only slightly less than white wheat flour and essentially the same as whole wheat flour.

History
Graham flour is named after Sylvester Graham (1794–1851), an early advocate for dietary reform. Graham despised the discarding of nutrients such as germ and bran when making flour for white bread. He believed that using all of the grain in the milling of flour and baking of bread was a remedy for the poor health of his fellow Americans during changes in diet brought on by the Industrial Revolution.
