Digestion is the process through which the body breaks down food into smaller molecules that can be absorbed and used for energy and nutrients. This process involves the mechanical and chemical breakdown of food in the mouth, stomach, and small intestine, with the help of enzymes and bacteria. Research in the field of digestion focuses on understanding the mechanisms and factors that influence the process of digestion, such as enzymes, hormones, gut microbiota, and other digestive processes. This research area also explores how digestion is affected by various health conditions, such as gastrointestinal disorders, food allergies, and obesity, and how diet and lifestyle factors can impact digestion and overall health. Additionally, researchers investigate strategies to improve digestion and promote better nutrient absorption, such as through the use of probiotics, prebiotics, and dietary modifications.
