The areas of "time" and "nutrition" are shaped by changes in the human environment. The technical and civilizational progress of the last century has influenced people's lifestyles and, with them, their nutrition more than ever before. Although people have never had as much free time as they do today due to this progress, many complain about a lack of time. The environment places numerous demands on individuals. Additionally, an oversupply of ways to use free time means that priorities must be set when it comes to time management. This leads many people to feel a sense of time scarcity, which impacts various areas of life. Saving time has become a necessity of modern living. This trend is also evident in the nutrition sector, highlighted by the increasing significance of fast food.
