Today the Department of Agriculture’s recommendation for dairy is a mere three cups daily — still 1½ pounds by weight — for every man, woman and child over age 9. This in a country where as many as 50 million people are lactose intolerant, including 90 percent of all Asian-Americans and 75 percent of all African-Americans, Mexican-Americans and Jews. The myplate.gov site helpfully suggests that those people drink lactose-free beverages. (To its credit, it now counts soy milk as “dairy.”)

There’s no mention of water, which is truly nature’s perfect beverage; the site simply encourages us to switch to low-fat milk.
