Refrigerators are a key part of a system that impacts culture and food choices. Firstly, they consume a lot of energy, especially old models, but new ones are more efficient due to stricter standards. Secondly, marketing encourages people to buy more prepackaged foods in the center of supermarkets, leading to a shift away from fresh and healthy options. Thirdly, food wastage is a significant issue, with about one-third of purchased food being wasted. Moreover, the trend of eating out contributes to obesity as restaurant meals are often high in unhealthy ingredients, partially due to people's fear of cooking at home.
