Disclosed embodiments provide methods and compositions for improving the metabolic health of consumers. Bovine beta-casein, a major component of milk from cattle, has a variety of genetic variants. Certain genetic variants, A1 in particular, have been associated with type 1 diabetes. The disclosed methods and compositions include reduced amounts of genetic variants of beta-casein that have been associated with diabetes. In some embodiments, the compositions display improved emulsions due to the solubility and hydrophobicity of the genetic variants of beta-casein used therein.
