9 Sins Against Superfoods

It's easy to think opting for sweet potato over regular fries is automatically a more nutritious move. And while it's true that sweets offer some extra health benefits over white taters like beta carotene and vitamin A, frying is more often than not bad news.

One of the biggest issues is the temperature of the oil as a fried food cooks: Not hot enough, and your food absorbs excess oil, leading to extra calories and fat on your plate. Your batter or breading could also absorb extra oil, not to mention certain oils are more nutritious than others to begin with. Frying does come in varying levels of unhealthfulness, but even the healthiest frying oil is something to enjoy in moderation. Pick peanut, soybean or canola oil, and use a fry thermometer while cooking for the healthiest possible outcome, according to Cooking Light.

Raisins pack fiber, iron, vitamin C and a hearty dose of potassium, but don't let that white coating fool you. Just because it's called yogurt doesn't mean this isn't candy.

We found one label that includes eight ingredients in that yogurt coating, including sugar and trans fats.

Grilled chicken or lean cuts of beef are excellent sources of protein and some iron to boot.

But how you adorn your meat can be equally important as the cut you select. Just two tablespoons of barbecue sauce -- and that's a pretty paltry amount -- packs nine grams of sugar, about the same as a quarter of a can of soda.

They may be tiny, but blueberries are surprisingly powerful, thanks to high levels of antioxidants for very few calories.

But in a number of store-bought products from manufacturers including Kellogg's, Betty Crocker and General Mills, you may find blueberry impostors. Bagels, cereals, muffins and more come complete with concocted "blueberries" made of "sugar, corn syrup, starch, hydrogenated oil, artificial flavors and -- of course -- artificial food dye blue No. 2 and red No. 40", the LA Times reported.

The low-calorie, high-fiber, antioxidant-rich snack is surprisingly nutritious -- if you air pop your own, that is.

A cup of air-popped kernels has no fat, barely any sodium and only 31 calories. But just one ounce of the buttery, microwaved stuff will set you back 148 calories, 216 milligrams of sodium and 8 grams of fat.

We wish people would stop messing with good ol' H₂O when it's so simple and perfect as is.

The ingredients lists of neon-colored, "enhanced" waters are padded with artificial sweeteners, colors and other chemicals we can't pronounce. We'll stick with lemon slices.

In case you missed it, what's really in your egg-white breakfast sandwich might scare you.

That's right, those are not just egg whites. Many of these breakfast offerings marketed as healthful choices have a whole host of other ingredients -- with some listing as many as 15.

With protein and calcium, you probably think you can't go wrong when it comes to selecting a yogurt. But those fruit-on-the-bottom varieties pose a particular problem: High fructose corn syrup and other artificial sweeteners.

Instead, buy a plain variety of your favorite yogurt and mix in your own real fruit.

The reigning healthiest salad green makes for a tasty, crunchy snack, but the verdict is in that homemade kale chips are leaps and bounds tastier than store-bought varieties. Why? That "thick, gunky coating of unidentifiable flavorings", according to our friends at HuffPost Taste. Depending on the flavor they're going for, manufacturers may add a heftier dose of sodium or sugar than you'd top your homemade batch with.
