Whether you refer to them as protein bars, energy bars, nutrition bars snack/meal bars or food bars, these food supplements share one important factor: convenience. Nutrition bars serve a wide variety of purposes for different populations:

  • Pre- or post-workout nutrition for athletes or active individuals
  • Between-meal snack to quickly curb hunger or low blood sugar
  • Increase daily protein or calorie consumption
  • Meal replacement

Additionally, these power-packed food bars have been shown to potentially support weight-loss programs. Several studies have suggested that protein-rich snacking may boost satiety and actually help to facilitate weight loss. In a 2011 longitudinal study, researchers gave 17 men and women with type 2 diabetes moderately high protein snacks in the morning and afternoon (7 to 12 grams of protein) for four weeks, and compared the results with their normal eating habits for four weeks. The subjects who ate the two high-protein snacks lost a modest, but significant amount of weight (1 kg) during the four-week period. Significantly, researchers noted that the subjects' weight reduction occurred without changes in total energy intake.

The nutrition and snack bar industry has seen a dramatic rise in sales in the last five years, and many predict that this market will reach $6.2 billion in sales by 2018.

With so many bars on the market, how do you choose which one is right for you? Here are five key factors to consider when choosing a bar:

  1. Quality of ingredients – The first thing you should look at is the ingredient list. What type of protein, sugars and fat does it contain?
  2. Purpose and application to goals - Will these bars help you meet your goal, such as weight loss/gain, fuel or energy, or improved health? Will the bar replace or supplement a meal (regular meal or pre-/post-workout)?
  3. Brand reputation – Does the brand have a good reputation? Reading online reviews of protein bars can help you identify high-quality brands.
  4. Value for the money – How expensive are the bars? Protein bars typically cost between $1 and $3 each, depending on the quality and brand. Compare ingredients and claims to make sure you don’t sacrifice quality for cost.
  5. Taste and flavor – Does the flavor sound good to you? Obviously you’ll want to choose a good flavor, so you actually want to eat the bars. Take advantage of consumer reviews and ratings, as these can be a great starting point for choosing the best flavors.
