Balanced protein bar vs. protein only


There are a variety of protein bars on the market to suit your snacking needs. If you’re looking for a balanced snack, aim for a bar with a carbohydrate, fibre, and fat source as well. If you’re looking for a bar to help contribute only your protein intake for the day, stick to a bar that has protein as the main macronutrient. Note: this will likely be a less filling and satiating option. 


Sugar-sweetened vs. Non-caloric Sweetener


Protein bars are flavoured with either sugar or non-caloric sweeteners. Whether or not non-caloric sweeteners are a better option than sugar remains controversial. There is debate as to the impact of these sweeteners on our hunger & satiety cues, whether or not we overcompensate with more calories or sweet foods later in the day after eating non-caloric sweeteners, and the impact on gut microflora and weight.


Whether you choose sugar-sweetened or non-caloric sweetener may depend on your overall health and nutrition goals. In general, I suggest reducing your overall intake of both added sugar and non-caloric sweeteners. Opt for a lower sugar-sweetened option or a bar with only one non-caloric sweetener in the ingredient list.


Ingredient list 


Some protein bars have a very long list of ingredients and tend to be more processed, while others contain a shorter list with more whole-food ingredients (ie. ingredients that you would likely use if you were making a protein bar at home). Consider the quality of ingredients used when looking at the nutrition information on each label.


Protein source 


From soy to whey to egg whites, there are a variety of protein sources available depending on the protein bar that you choose. When comparing products, keep in mind that the majority of protein in your diet should come from whole food sources and not protein bars or other supplements. Getting a variety of protein sources in your diet is best, so this could be an opportunity to try a protein bar with a different protein source than you typically include in your diet.
