Food is fundamental to everyday living. Without food—the body doesn’t function. Eating too many of some foods, or too much, and omitting others, leads to poor health outcomes. However, food is also part of “living.” Daily routines, habits, and conventions shape what is consumed, and how much—often without immediate or deliberate reflection, meaning choices are embedded within the backdrop of life. Additionally, eating is pleasurable. The experience involves a sense of anticipation followed by physical sensations in response to flavor, texture, and even temperature, meaning some choices are pursued their visceral rewards rather than their functional properties. Moreover, people gather around food and share it—creating daily rituals and elaborate celebrations. For the majority of people, food and eating fulfill several purposes—providing nutrients for the body, a range of enjoyable sensations, a sense of routine or structure to the day, and an opportunity to share connect and bond with others.
