Whether you need fuel on a long hike or are craving a chewy snack to power through an afternoon at the office, a granola bar is a convenient, delicious way to pack in some whole grain goodness.

Typically sweet and often flecked with chocolate chips, some granola bars are comparable to candy bars when it comes to sugar. And most products on the market are low in satiating fiber and protein, leaving you hungry for more within minutes. However, there are some excellent options that are packed with fiber, protein, and whole grains that will keep you full and energized for hours.

Here, the best granola bars, as recommended by a dietitian.

What to Look for in a Granola Bar


When looking for a granola bar, consider your individual needs. Some granola bars contain allergens such as nuts, soy, or dairy that may not be suitable for all individuals. Especially for school-age children who are required to pack allergy-friendly snacks for school, an allergen-free bar may be best whether or not the child has dietary restrictions.

When possible, look for a bar made with non-GMO and organic ingredients. Avoid bars with artificial colors, flavors, and sweeteners. Always take a look at the ingredient list to ensure that you recognize all of the components.


Some granola bars are super high in sugar but lack dietary fiber. Dietary fiber helps to keep you fuller longer and is a nutrient that most Americans don't get enough of. Choosing a bar that contains 3 or more grams of fiber can help you meet your recommended 25 to 34 grams of fiber per day. 


It's common for granola bars to be fairly low in protein, Many are made primarily from oats, which are higher in carbohydrates than protein. If you're looking for a granola bar with higher protein, you may want one that contains a natural protein source such as nuts or seeds. In general, choose a granola bar that has at least 2 grams of protein.

Sugar and Carbohydrates

Most granola bars are high in sugar and carbohydrates, as they are made up of oats and sweeteners combined with dried fruits or chocolate. When possible, select a bar that is made up of whole grains, which contain higher levels of fiber than refined carbohydrates and take longer for the body to break down. Choose a bar that contains 10 grams of sugar or less per serving.

Frequently Asked Questions

  • Are granola bars nutritious?

    Granola bars offer many important nutritional benefits.  They are an easy and convenient source of carbohydrates necessary for energy during that 3 p.m. slump.  The combination of protein and fiber in granola bars provides the most staying power to keep you fuller for longer.

    Certain varieties even have added micronutrients such as calcium and potassium.  Be mindful of sugar content in granola bars, as any with over 10 grams may leave you feeling hungry within an hour after snacking. 

  • What is the shelf life of a granola bar?

    Unopened packaged granola bars can generally last anywhere from 6 to 8 months. They should be stored in a cool, dry area of your pantry. 

    While there is likely a “Best Buy” or “Best if Used By” date on the package, this indicates when granola bars are at their peak quality.  They are still safe to eat after this date, but their texture or flavor may change. Check the granola bar for off odors or appearance to determine if it should be thrown away.

    Bars made from almond flour have a shorter shelf life of about 3 months due to almonds’ tendency to go rancid. 

  • How do granola bars impact digestion?

    Granola bars often have a positive effect on digestion as the fiber helps with regulating the digestive tract. Additionally, if the bar is made from oats, it contains a good source of prebiotics, which are food for the good bacteria in your gut.

    Be mindful of granola bars with artificial sweeteners such as xylitol, sorbitol, and aspartame, as they are not broken down in the digestive system and may cause stomach upset.
