Caution

Insulin and the Vegetarian Diet

Insulin is a peptide hormone produced by beta cells in the pancreas. It is a critical component in the regulation of glucose metabolism, facilitating the uptake of glucose into cells and thus, lowering blood sugar levels. While naturally occurring in the human body, insulin used for medical purposes is often synthesized using recombinant DNA technology, though it can also be derived from animal sources such as pigs or cows.
