Over the past century, major changes in the way we live and work have changed what we eat. Since the 1950s, the food industry has developed a wide variety of processed foods, which reduce preparation time. The popularity of these convenience foods reflects the ways in which our lives have changed, and the choice that many of us have made to spend less time in the kitchen.

Many consumers do not have the time, inclination, or skill to prepare complex meals or to make something from scratch. Instead, they choose to buy partially cooked foods, baked goods, frozen dinners, and even precut fruits and vegetables.
