Graham bread - online puzzles
Graham bread was inspired by Sylvester Graham, a 19th-century reformer who argued that a vegetarian diet, anchored by bread that was baked at home from flour that was coarsely milled at home, was part of a healthy lifestyle that could prevent disease.
Like Graham crackers, Graham bread was high in fiber and made from graham flour free from the chemical additives that were common in white bread at that time such as alum and chlorine. He argued that these chemical additives were unwholesome.
