Why We Eat

This article explores the complex relationship between eating behaviours and mental health, emphasising the role of the gut-brain axis in regulating both. It discusses how gut microbiota influences mental health, including conditions like anxiety, depression, and eating disorders. The article highlights the importance of maintaining a healthy diet and understanding the biological mechanisms behind eating, such as the roles of neuropeptides like ghrelin and orexin, which regulate hunger and sleep. It also touches on the impact of modern societal changes on eating habits, suggesting that understanding these biological processes can help mitigate disorders related to both under-eating and over-eating.
