Which hormone is secreted by the F cells of the pancreas in response to food intake?

The hormone secreted by the F cells of the pancreas in response to food intake is pancreatic polypeptide. This hormone plays several roles in the regulation of both the digestive process and appetite control. After a meal, pancreatic polypeptide is released, contributing to the regulation of food intake by serving as a signal to help reduce appetite and control the release of other digestive hormones.

In addition to assisting in appetite regulation, pancreatic polypeptide also has effects on gastrointestinal motility and can influence the secretion of digestive enzymes. The secretion of this peptide hormone is often triggered by the ingestion of food, particularly protein-rich meals, making it an important player in the postprandial state.

Understanding the role of pancreatic polypeptide helps to appreciate how various hormones interact within the complex hormonal ecosystem of the body, particularly in relation to food intake and energy balance.
