To the Editor: In their categorizations of
dairy products, Dr Pereira and colleagues1
excluded foods for which the "contribution of dairy to the weight or caloric
content of the item was unclear or likely to be minimal." Such "mixed dishes"
included pizza and cheeseburgers. Thus, for example, a study participant could
have eaten 3 double-cheese pizzas in a day, but his daily intake would not
have been counted as a dairy day if he did not drink milk.
