By Craig Stellpflug(NaturalNews) We have the wrong cows! Black and white milk cows produce milk that contains a portion of protein called beta casein type A1, which behaves like an opiate. Studies implicate this bad-for-human protein in heart disease, cancer, Type I diabetes, autism and schizophrenia. This maverick protein also causes milk addiction. But addicted drinkers are repeat customers that increase profits, making the bad milk the sweetheart that producers prefer to sell.A few thousand years ago, the majority of milk cows were the wholesome beta-casein A2 type until the genetically mutated beta-casein A1 strain appeared. Today, over 90 percent of US milk cows are the errant A1 type cows.
