What is the link between cow’s milk and diabetes?

Early exposure to cow’s milk formula has been linked to an immune response that can lead to type I diabetes in some children. The immune response involves the body’s immune system reacting to a trigger (which may be cow insulin or a protein called casein from cow’s milk). Structural similarities between the triggering molecule and the insulin-producing pancreatic beta cells confuse the human immune system and it attacks the cells in the pancreas. This limits the ability to produce insulin and may lead to diabetes. The avoidance of cow’s milk during the first few months of life may reduce the risk of type I diabetes in some children.
