This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"The balance between hunger and satiety plays a key role in metabolic health. Specifically, disrupted appetite can lead to eating disorders or obesity. Appetite control is influenced by a complex web of factors - including our gut microbiota. Gut microbiota influence appetite through a variety of mechanisms, including regulating appetite-related hormones such as leptin, ghrelin, and insulin, influencing the immune system and acting directly on hypothalamic neurons. Recently, there has been interest in exploring the gut-microbiota-brain axis in several research fields. Some research has suggested that the gut microbiota can regulate host body weight and even psychiatric disorders, but the effects of gut microbiome interventions have been inconsistent and require more research. Overall, there are many links between gut microbiota and host appetite, but the interaction is complicated by many outside variables, and the precise mechanisms have yet to be fully deciphered..."

This is a comprehensive overview of eating disorders and associated issues, containing 13 chapters and aimed at an undergraduate psychology or sociology audience.

This course encompasses the study of eating as it affects the health and well-being of every human. Topics include taste preferences, food aversions, the regulation of hunger and satiety, food as comfort and friendship, eating as social ritual, and social norms of blame for food problems. The politics of food discusses issues such as sustainable agriculture, organic farming, genetically modified foods, nutrition policy, and the influence of food and agriculture industries. Also examined are problems such as malnutrition, eating disorders, and the global obesity epidemic; the impact of food advertising aimed at children; poverty and food; and how each individual's eating is affected by the modern environment.
