A1 and A2 Milk

Summary of Concerns Regarding A1 and A2 Milk and Dairy Breed Rankings

In a recent Weston A. Price Foundation (WAPF) “Nourishing Traditions All Thumbs Book Review” article describing “Devil in The Milk: Illness, Health and The Politics of A1-A2 Milk”, a statement was made that has been repeated often and is still erroneous. The reviewer states that “old fashioned” cows…(such as Jerseys, Asian and African cows)” are called A2 cows and have the original beta-casein amino acid configuration. He also states that “more modern breeds like Holstein” are called A1 cows. Many WAPF farmers and raw milk consumers have used this statement as guidance in selecting cattle or milk supply sources.
