What exactly is it that vegetarians eat? That's a question asked by researchers in the American Journal of Clinical Nutrition, which devoted much of September's issue to the study of those who eat no meat, poultry or fish. Or, at least profess that they don't. It turns out that a number of people who report being vegetarians actually consume meat, poultry and fish regularly. They just eat these foods less often than the rest of the nation's omnivores. In a study of daily food records from more than 13,000 Americans collected by the U.S. Department of Agriculture, Loma Linda University researchers discovered that fewer than 1 percent of those surveyed (including self-described vegetarians) reported eating no animal flesh when quizzed in detail about their eating habits.
