The quality, state, or practice of having or promoting good digestion; a medical philosophy emphasizing digestive health.
From eupeptic plus the suffix '-ism' (a system, practice, or condition), created following 19th-century medical terminology patterns that turned descriptive terms into philosophical schools or conditions.
Eupepticism was basically a real medical movement—doctors believed perfect digestion was the key to all health, leading to obsessive dietary advice that predates wellness culture by 150 years.
