That's the paradox noted in a June 30 article by J.M. Hirsch, but he also notes:
Ruth Kava of the American Council of Science and Health said recently that data such as these indicate that despite a flood of nutrition advice, people may actually understand very little about healthy eating.
She has no doubt people believe they are eating good diets, but said the reality probably is quite different, in part because many people confuse eating healthy foods with having an overall healthy diet.
"People say they have a healthy diet, but what does that mean to them?" Kava said. "Does it mean they eat an apple a day and the rest of the day eat burgers and french fries?"
