Different β-Casein Fractions in Icelandic Versus Scandinavian Cow's Milk May Influence Diabetogenicity of Cow's Milk in Infancy and Explain Low Incidence of Insulin-Dependent Diabetes Mellitus in Iceland

Abstract

Cow's milk consumption in infancy is not related to IDDM in Iceland. The lower fraction of A1 and B beta-caseins in Icelandic cow's milk may explain why there is a lower incidence of IDDM in Iceland than in Scandinavia.
