Once upon a time we used to eat food simply because we liked it. Now we buy into diet plans such as Atkins and South Beach, and fill our grocery carts with fish, almonds, orange juice fortified with Vitamin D and other foods we think are healthy. Then, on those special days when we want to treat ourselves for being good, we seek out foods marketed as sinful and indulgent. Double-fudge brownies, anyone? Somewhere in between, however, people are losing touch with the basic joys of the table. To blame? Our Puritan roots, perhaps. Or, new information about the nutrition-related causes of illnesses like heart disease. Then there's the increasing influence of a massive diet industry as well as food manufacturers trying to find new ways to catch our eye. Myth One Fresh Is Best While our grandparents chose canned foods because they were safe and efficient, today, we've gone to the opposite extreme. We tend to think anything artificial is inferior, Glassner says. But flash-frozen vegetables, for example, retain more nutrients than their fresh counterparts, which age during transportation and sitting on the shelf. Myth Two Vitamin-Enhanced Foods Are Better By blurring the line between food and vitamins or medications, we tend to think we're getting a two-for-one deal with products, such as pasta packed with omega-3 fatty acids. But with these extras, foods don't necessarily become better for you. What's more, they are altered in the process. Myth Three A Meal Is Worthy For What It Lacks Glassner believes most people have lost sight of what should be an obvious fact--that what's on the plate is what makes a meal great and a source of pleasure. Too many people, he says, focus on the lack of salt, fat, carbs or calories in a dish, rather than its taste, when sizing it up. Myth Four Natural Means Less Processed Many foods with the word "natural" on their labels are in fact more processed and have less nutritional value than others without it, Glassner says. The only thing the term seems to consistently mean is a higher price. Myth Five Some Foods Are Inherently Bad For You Too much of anything isn't good for you. Eat three meals a day of broccoli and you're probably going to get sick. Gorging only on snack foods likewise is a bad idea. But foods like potato chips, which most of us enjoy, can still have a place in our diet. Categorizing a food as inherently bad is unnecessary, Glassner says.
