A meal high in carbohydrates will most likely trigger the release of the hormone insulin. Insulin secretion significantly increases following ingestion of a carbohydrate-rich meal. This hormone plays a critical role in stimulating blood glucose uptake into cells and promoting anabolic processes such as protein synthesis. The response of insulin to carbohydrate intake is well documented and is a key mechanism for regulating blood glucose levels after eating.
Other hormones like cortisol and glucagon may also be affected by food intake, but insulin is the primary hormone released in response to a high carbohydrate meal to help manage blood glucose.
