“Reduce Intake, Increase Longevity” – Health Preservation Philosophy
In the Jiaodong Peninsula, the saying “reduce intake, increase longevity” is widely circulated. At first glance, it seems counterintuitive, but from a disease-prevention and health-preservation perspective, it makes perfect sense.
As people age, metabolic functions across all systems gradually decline. If one eats to “ten-tenths full,” it increases gastrointestinal burden, causes energy surplus, and leads to obesity, hypertension, coronary heart disease, etc. By moderately reducing food intake, one not only prevents disease but also delays brain aging. Overeating triggers rapid growth of a substance called “fibroblast growth factor” in the brain—this is the primary culprit behind cerebral artery hardening, a major cause of dementia in the elderly.
Traditional Chinese medicine also states: “Excessive eating is the root of all diseases.” Ancient statesman Guan Zhong said: “Eating with moderation benefits the body and extends life; eating without restraint burdens the body and shortens life.” Moderation in diet is indeed an effective health-preserving practice. Therefore, older adults with heavier builds would do well to restrain their appetites and achieve longevity through “reduced intake.”
