Sylvester Graham,
A Treatise on Bread, and Bread-making
(1837)
“ It is incontestibly true, that if two portions of the same kind of wheat meal be taken and made, the one into unleavened and the other into leavened bread, and both be eaten warm from the oven, the leavened bread will prove much more oppressive and difficult to manage in the stomach than the unleavened. But aside from the changes that are produced by the process of fermentation, there are many other considerations why unleavened bread of a proper quality and age, is better 29adapted to sustain the alimentary organs and general constitution of man, in their highest and best condition. ”
