>>3746994Bread is a staple food prepared from a dough of flour and water, usually by baking. Throughout recorded history it has been a prominent food in large parts of the world; it is one of the oldest man-made foods, having been of significant importance since the dawn of agriculture; and plays an essential role in religious rituals and secular culture.
Bread may be leavened by naturally occurring microbes, chemicals, industrially produced yeast, or high-pressure aeration. In many countries, commercial bread often contains additives to improve flavor, texture, color, shelf life, nutrition, and ease of production.
