KANSAS CITY — The snack bar market has been on a steady incline over the past two years and is set to surge well into the next four, according to market research company Research & Markets. The U.S. snack bar market was valued at $6.8 billion in 2017 and is expected to reach $8.8 billion by 2023.

“Consumer demand for convenient and healthy on-the-go snack options has by far been the primary attribute for sales of snack bars in the U.S.,” Research & Markets said. “The changing lifestyle of consumers involving the consumption of smaller meals is further leading to the increased consumption of snacks, which is expected to propel the demand for snack bars. Owing to the availability of a wide range of flavors within various snack bar categories, the demand in the U.S. for snack bars grew considerably.”

General Mills, Inc. is taking a bite out of the snack bar segment with its new Nature Valley Crispy Creamy Wafer Bars. Available in peanut butter and peanut butter chocolate varieties, the bars consist of layers of wafers, peanut butter and oats on top. The peanut butter chocolate flavor is topped with oats and a layer of chocolate. Individually wrapped for on-the-go consumption, the bars contain 200 calories apiece.

“Consumer preference for clean label ingredients is evidently high,” Research & Markets said. “Snack bars have various opportunities within functional ingredients, reduced sugar, savory spins and plant proteins, which is a fueling factor for the growth of the U.S. snack bar market.”

Peanut butter provides the plant protein in the J.M. Smucker Co.’s two new Jif Power Ups bar lines: Soft Baked and Triple Stacked. The bars are all individually wrapped and contain five grams of protein and two grams of fiber each.
