This issue of Sight and Life Magazine focuses on food culture and we have curated contributions that explore the social and cultural domains of food choices and food experiences more broadly. We acknowledge that this is only part of the story. We promise to explore cognition (psychology, brain) and biology (evolution, genes, biochemistry) – factors that also drive food choices – in a future issue of the magazine. For some of our readers trained in biology or chemistry, culture may seem a fuzzy, perhaps non-scientific, topic. Be assured, however, that culture is as much part of nutrition as are biology, biochemistry, chemistry, and genes, and there is a rich body of research on nutrition and culture.
