National Granola Bar Day is observed each year on January 21. The day recognizes the granola bar’s evolution from 19th-century health foods to a widely used convenience snack, popularized in the late 20th century by brands such as Quaker Oats.
Its purpose is to highlight granola bars as practical, portable sources of energy that fit modern routines, from outdoor activities to school lunches and busy workdays.
How Granola Bars Developed
Granola’s roots trace back to the 1860s when Dr. James Caleb Jackson developed granula, a health-focused cereal made from graham flour. Decades later, Dr. John Harvey Kellogg adapted this idea, renaming it granola to avoid legal conflicts. Over time, the cereal gained popularity, especially with health-conscious crowds and counterculture movements of the 1960s, including Woodstock attendees who enjoyed granola as a handy, nutrient-rich snack.
By the 1970s, granola’s popularity led to the first commercial granola bar, produced by Nature Valley in 1975. Since then, granola bars have evolved to suit modern dietary preferences, offering options that are gluten-free, organic, and packed with superfoods.
