Some of the nutrients found in bread include protein, thiamine, niacin, riboflavin, iron and calcium. The amount of nutrients differ with the type of bread consumed, with whole wheat and grain bread having higher amounts of nutrients.
Wheat is a component of all types of bread, even white bread. Nutrients commonly found in larger quantities of wheat include B vitamins such as riboflavin and thiamine. One hundred grams of bread can contain approximately 15 percent of calcium and 30 percent of thiamine toward a human's nutritional needs in their diet. A person should eat bread daily — along with other grains — as part of a balanced diet.
