Lynn Grieger, a registered dietitian and certified diabetes educator, says, "This is a huge matter for debate. I much prefer that people get their vitamins and minerals from unprocessed foods -- meaning primarily fruits, veggies and whole grains. Just because a food has a name that sounds good for us, doesn't mean it follows through with that claim."

Fast-food salads. Fast-food chains are attempting to shape up their reputations by offering healthy alternatives to the usual burger-and-fries combo. But a number of salads on their menus are extremely high in fat and sodium.

McDonald's Bacon Ranch Salad with Grilled Chicken (no dressing) contains cheddar and jack cheeses, bacon bits and liquid margarine amounting to 260 calories (90 of which come from fat) and 1,010 grams of sodium. A McDonald's Hamburger contains slightly fewer calories with about half the sodium (granted, the salad is nearly three times the size of the burger).

Fruit juices. Though doctors recommend you eat a variety of fruits to meet your daily requirement of vitamins, drinking fruits isn't comparable. Many packaged and processed juice drinks are loaded with sugar or high-fructose corn syrup, artificial flavoring and very small amounts of actual fruit juice. That adds up to nothing more than a lot of empty calories in a single serving. Even drinks that are 100 percent juice lose fiber and possibly nutrients during processing. Try eating a nice juicy orange or tangerine instead!
