In the early 1980’s, the Japanese were the first to recognize dairy components as having significant contributions to “physiologically functional foods.” Since then there has been an increasing number of investigations that have supported this view.Current evidence for the health benefits of most dairy foods and dairy components is based primarily on in vitro and in vivo animal studies. Human clinical studies are still needed in many areas. | WHEY PRODUCTS AS FUNCTIONAL FOODS W.
