National Granola Bar Day

National Granola Bar Day, observed January 21st, celebrates the compact, portable snack made from oats, honey or other sweeteners, and mix-ins like nuts, seeds, and dried fruit, pressed and baked or set into a bar. Granola itself was invented in the United States in the 1860s by Dr. James Caleb Jackson at a health spa in New York as a whole-grain breakfast cereal, and it was later refined and commercialized by Dr. John Harvey Kellogg. The modern granola bar format, however, is a much more recent invention, emerging in the 1970s as health food and fitness culture grew and companies like Quaker Oats and Nature Valley developed shelf-stable, individually wrapped bars aimed at hikers, athletes, and on-the-go snackers looking for a more convenient alternative to a bowl of cereal. Granola bars quickly became a lunchbox and pantry staple thanks to their long shelf life and portability, and the category has since expanded to include chewy, crunchy, protein-forward, and low-sugar variations. On National Granola Bar Day, people celebrate by snacking on a favorite bar, trying a new flavor, or making homemade granola bars from scratch.
