The Mercury News reports on the rise of products catering to those with lactose intolerance. There’s a website, No-Dairy.com, devoted to lactose-free groceries and food products. According to this page: “There are an estimated 50 million lactose intolerant adult Americans, including 70% of the black population, 15% of the white population, and 80 to 97% of Jews of European descent and Asian-Americans. Eskimos, Native Americans, and South American Indians are other highly lactose intolerant groups.” Also, there is a correlation with the presence of lactase in populations with a long history of herding animals and relying on their milk for food. No big surprise there!
