The US Department of Agriculture (USDA) suggests the grain category is the largest segment of American dietary consumption, encouraging consumers to eat at least five ounces of grain products every day. From snack cakes, energy bars, cookies, crackers, rolls, donuts, pastries, pie, pizza crusts, cakes and muffins, and fortified breakfast cereals, bakery manufacturing covers a very broad range of foods. Since the average American eats more than 50 pounds of bread and more than a 100 pounds of cereal each year, it represents billions of dollars in revenue for bakers; the worldwide market for bakery products is now greater than $300 billion annually.
