2007 was another banner year for misinformation, swamp remedies, idiocy, and plain outright lies about diet and weight, subjects that obsess Americans far more than the future of Iraq or the solvency of Social Security. Nutritionist and dietician Tanya Zuckerbrot told Foxnews how some foods aren’t as health as people think.

10 healthy foods that aren’t:

1. Olive oil: Sure it’s a heart-healthy monounsaturated oil, but it’s also rich in calories and fat. “Oil is oil,” Zuckerbrot said.

“Whether it’s olive oil or some other kind of oil, it still has 120 calories and 14 grams of fat per tablespoon. You’re better off using a pat of butter (for bread) than dipping it in olive oil because the bread sops up the oil like a sponge. So a little bit of butter is better than a lot of olive oil.”

2. Tuna fish: Think that tuna sandwich is a light lunch? Think again. The average overstuffed tuna sandwich served in a restaurant contains 700 calories and 43 grams of fat.

The reason? The mayo. “Tuna fish has just 35 calories per ounce and it’s full of omega-3s, but mayonnaise has 100 calories per tablespoon,” Zuckerbrot said. “You’re better off having a turkey or even a roast beef sandwich. Even chicken salad is better than tuna salad, because tuna is so fine there’s a lot more surface area for the mayonnaise to fill.”

3. Granola: The term granola may be used to describe health-conscious people, but the cereal itself is actually quite fattening. That’s because granola cereals often contain oils, including high in saturated fat coconut oil, sugar, nuts and other high calorie foods.

“Something like Fiber One has 60 calories per half cup and 14 grams of fiber versus a half cup of granola, which was 240 calories, 5 to 10 grams of fat and just 3 grams of fiber,” Zuckerbrot said, adding that fiber is the key to feeling full and satiated.

4. Organic food: Organic food may be preservative and pesticide free, but that doesn’t mean it’s also calorie-free, said Zuckerbrot. “I mean they make organic potato chips so what does that tell you,” she said.

5. Sushi: Tuna sashimi is very healthy. A California roll or tempura roll, not so much, said Zuckerbrot.

“Japanese food is inherently healthy, but when you Americanize it and start adding things like cream cheese and avocado, that’s when you run into problems,” she said.

6. Pizza: “Yes the sauce is high in lycopene, but all the lycopene in the world is not going to convince me pizza is a heart-healthy food,” Zuckerbrot said. “And mozzarella cheese is a good source of calcium, but it’s also high in calories.”

7. Frozen diet meals: Sure Lean Cuisine and Weight Watcher frozen entrees are fairly low in calories and convenient, but they’re also highly processed and high in sodium.

8. Protein bars: Another convenient food, but not very nutritious. Zuckerbrot describes protein bars as her least favorite food and said they are basically glorified candy bars. They’re also often high in calories, fat and do little to satisfy a person’s hunger.

A better choice, said Zuckerbrot, is hitting the salad bar and grabbing lots of lettuce, artichokes and broccoli, topped with plain balsamic vinegar. For 100 to 200 calories, you get a lot more for a lot less calories.

9. Pretzels: They’re low in fat and low on nutrition. “They’re basically empty calories,” Zuckerbrot said. “Inherently, pretzels themselves are not unhealthy, but they’re basically all sugar so they’ll make you hungrier and you’ll gain weight as a result of over-eating.”

10. Fat-free, sugar-free muffins: Regardless of whether a muffin is fat free or sugar free, they still usually have around 600 calories, according to Zuckerbrot.

“It’s nothing but cake in disguise, especially these double chocolate chip-type muffins,” she said. “But even bran muffins, they’re very dense, very high in calories. The same thing goes for scones.
