Is a LUNA Bar a Healthy Snack?

LUNA Bar balances positive nutrition attributes with mouthwatering flavors and textures — making it a bar you can feel good about reaching for when you need a tasty snack. LUNA Bars contain gluten-free whole grains and plant-based protein, and most flavors provide a good source of fiber,* which is a beneficial nutrient many of us need more of in our diets.

*Contains 6-10 grams of total fat per serving. Blueberry Bliss does not provide a good source of fiber.

You may notice that we don’t label our products as “healthy” on the package. That’s because the Food and Drug Administration (FDA) has an official definition for the term “healthy.” According to the FDA, healthy foods are low in total and saturated fat, have limited sodium and cholesterol, and provide a good source (at least 10% of the daily value) of specific vitamins or minerals.1,2 LUNA Bars do not meet this FDA definition, but they can still contribute to an overall healthy diet.

The Dietary Guidelines for Americans encourage us to build healthy dietary patterns by choosing foods and beverages that contribute positive nutrients (i.e., vitamins, minerals, fiber) and foods groups (i.e., fruits, veggies, whole grains, lean protein) to our day.

At LUNA, we are dedicated to bringing you delicious on-the-go snacks that fit your lifestyle anytime you need a feel-good break.

Is a LUNA Bar a Sustainable Snack Option?

With our focus on sustainability, a LUNA Bar is both nutritious and good for the planet. In every bar, you’ll find plant-based, organic ingredients like rolled oats and cocoa. While a LUNA Bar doesn’t bear the USDA organic seal, the majority of the ingredients are organic. Organic farming conserves and restores biodiversity, and it stores carbon in the soil where it increases soil fertility instead of releasing it into the atmosphere.3,4

All LUNA Bars are also non-GMO and plant-based, meaning they’re suitable for vegetarians.

Are LUNA Bars a Meal Replacement?

At about 200 calories per bar, LUNA Bars are intended to be a snack, not a full meal replacement. With whole-grain carbohydrates and 7-9 grams of plant-based protein, LUNA Bars are a wholesome snack that can be eaten on the go whenever you need to satisfy your tastebuds with balanced nutrition — whether you’re on your way to work, school, or an event, commuting or traveling, or when you simply need an in-between-meals snack.

Are LUNA Bars for Women?

LUNA Bars are for everyone! Men can absolutely enjoy a LUNA Bar, and they’re appropriate for adults of all ages, too. LUNA was founded for women, but it can be eaten by all genders.

LUNA is a brand with a long history of supporting women. Since its founding in 1999, LUNA has been on a mission to create momentum, champion women, and spark change — to fuel women’s ambitions as well as their bodies. Our longest running program is LUNAFEST®, a traveling film festival that celebrates and showcases women in film, with over 2,700 screenings and 170+ women filmmakers featured. To date, LUNAFEST has raised over $6.5 million to directly benefit local women’s causes. Learn more about LUNAFEST 2022.

What Is the Role of Sugar in a LUNA Bar?

Depending on the flavor, there’s between 6 and 10 grams of added sugar in a LUNA Bar — which helps contribute to their delicious flavor and texture as well as helping to give you some energy for your busy day. Their good source of protein and fiber† and wholesome ingredients all contribute to their low-glycemic status.‡ Low-glycemic foods digest slowly and help maintain blood sugar levels for steady energy.

†Contains 6-10 grams of total fat per serving; Blueberry Bliss Flavor does not provide a good source of fiber.

‡LemonZest® Flavor, Blueberry Bliss Flavor, and Mash-Ups flavors are not low glycemic.
