My friend Justine is Chinese-American, and her parents are doctors who practice holistic Eastern medicine. She shared the following folk belief with me:
“I guess like, it’s a tradition to always eat fruit before going to bed, like you have to eat fruit before you go to bed cause that’s like, it’s better for your body and like it’ll help your immune system too. But I wonder if that’s actually helping, or if it’s more like a- it’s just something that a lot of people do. And I find that that’s like, [a common belief] across all Asian, especially Eastern Asian people.”
Like many folk beliefs and practices in East Asian medicine, this one is not necessarily based in empirical scientific proof, but this does not mean there is no truth to it. Remedies and folk beliefs formerly dismissed as “superstitious” have often been tested and proven effective by the medical/scientific institution, and subsequently incorporated into Western medicine. This belief reflects a general practice in Eastern medicine of focusing on overall bodily wellness rather than quick cures for acute illness.
