Granola (originally 'Granula') was invented in 1863 by Dr. James Caleb Jackson in upstate New York as a health food for sanitarium patients; John Harvey Kellogg later developed his own version. The name 'granola' was popularized in the 1960s American counterculture, which is why the word also doubles as a stereotype label for crunchy/health-conscious lifestyles. In Chinese supermarkets you'll see
格兰诺拉麦片 ('granola cereal') or
燕麦麦片 (yànmài màipiàn, 'oat cereal') as the typical packaging label.
