Insulin

Definition

Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels by facilitating the uptake of glucose into the cells.

Scientific / Technical Definition

Insulin is a peptide hormone produced by beta cells of the pancreatic islets, and it is considered the main anabolic hormone of the body. It regulates the metabolism of carbohydrates, fats, and protein by promoting the absorption of glucose from the blood into liver, fat, and skeletal muscle cells.

Benefits

• Helps maintain normal blood sugar levels.
• Promotes the storage of glucose as glycogen in the liver and muscles.
• Supports protein synthesis and muscle growth.
• Helps regulate fat storage by promoting lipid synthesis.

Examples

• Insulin is not directly found in foods; it is a hormone in the body.
• Foods that influence insulin release include carbohydrates like bread, rice, and pasta.
• High-protein foods can also influence insulin response, such as lean meats and legumes.

Additional Information

• Importance: This hormone is crucial for maintaining energy balance and muscle development, especially in response to nutrient intake.
