Choosing The Right Energy Bars

(CBS)  Grocery and convenience store shelves are packed with an ever-increasing number of energy bars — a "grown-up version" of the traditional granola bar — each claiming big benefits in a small package.

Organic Style magazine editor-in-chief Peggy Northrop discussed on Friday's The Early Show how to decide which granola bar is beneficial, and -- just as important -- which are tasty.

Packages proclaim their products are high in protein, low in carb, made for women, fortified for athletes — and the list goes on. So what's the real story here? Are there true differences? Or are all of them just candy in disguise?

Northrop says there are a million different energy bars in stores, all claiming big benefits in small packages. But the first thing to keep in mind, according to her, is that all of the "energy" in energy bars comes from calories.

She says many people mistakenly think they can snack on the bars in-between meals guilt-free. However, eating a calorie-laden bar can potentially result in weight gain, even if the bar does have beneficial vitamins and minerals. While there are plenty of bars out there that have less than 200 calories (110 seems to be the lowest, 160 or 180 more common), there are lots that have 220, 260 and over 300.

Nutritionists say that most don't need a sports bar, protein bar or energy bar before or after a typical workout because it defeats the purpose of burning calories. Northrop says they make more sense for an athlete training for a marathon or a family on an all-day hike.

Some of the bars are touted as meal replacements. While eating one for lunch or breakfast occasionally won't hurt you, Northrop does not suggest doing so on a regular basis. She says you still need nutrients that naturally occur in real food. If you do use a bar as a meal replacement, try to pair it with a glass or milk or piece of fruit.

Northrop does note that the bars are still healthier than potato chips or a candy bars. She says the key to having them is not misusing the bars.

There are several energy bars aimed at women that do provide essential nutrients often absent from women's diets, such as folic acid and soy, according to Northrop.

She says there are three common reasons people eat energy bars. They are:

To Boost Flagging Energy and Fight Hunger Between Meals

Northrop warns when looking for protein, steer clear of hydrolized protein because it's code for animal hooves. Instead, look for soy or other high-quality proteins. Also look for at least 5 grams of protein and 3 or more grams of fat to keep you satisfied. And try to get lots of nutrients and a maximum of 200 calories.

She suggests:

Luna Orange Bliss
AllGoode Chocolate Delight
Organic Real Food Bar
Pria Bar Chocolate Honey Graham

To Sustain Energy During a Long, Low-Impact Walk/Hike

Northrop recommends to look for at least 10 grams of protein and more than 3 grams of fat to slow the digestion and absorption of food. Also try to get bars with more than 200 calories.

She suggests:

Cliff Bar Peanut Toffee Buzz
EAS Results for Women Fresh Wild Berry

To Help Get Through a Sustained, Intense Workout

More than 30 grams of carbohydrates and less than 3 grams of fat is recommended by Northrop. This combo will also be easy to digest so it doesn't upset your stomach.

She suggests:

PowerBar Oatmeal Raisin
Odwalla Bar Cranberry C Monster
