The U.S. Department of Agriculture recommends children ages 9 and older and adults consume at least 3 cups from the dairy group each day. Active teenagers with high calorie requirements of 3,000 calories or more may require 4 cups from the dairy group each day.
And one of the big differences between its advice and the USDAâs relates to milk and dairy products. In 2005, the USDAâs dietary guidelines increased the recommended servings of milk from two to three cups a day. The latest guidelines, released in 2010, repeat that advice. They specifically urge Americans to get more fat-free or low-fat milk and related dairy products. According to Harvardâs food pyramid, on the other hand, milk isnât an essential part of a healthy diet -- and may pose risks.
