Graham crackers have changed a lot since their creation. Most "graham crackers" made today contain refined, bleached white flour, with sugar, honey and other sweeteners; sometimes cinnamon or chocolate to enhance the taste. Commonly considered a snack food.

Technically, graham crackers are not really "Graham Crackers" unless they are made with graham flour, which is simply a coarsely-ground hard whole-wheat flour.

A bit of History:
The graham cracker was created in 1822 in New Jersey, and named after Presbyterian minister Rev. Sylvester Graham, one of the earliest health food evangelists. Originally created as a health food, was more like a digestive biscuit than a cracker. The true graham cracker is made with graham flour, which is unsifted and coarsely ground wheat flour. He used this due to its high fiber content and to suppress what he considered unhealthy urges. These urges were believed to be the source of many maladies at the time.
