Japan is an exceptionally healthy East Asian country with extended longevity. In addition, the typical levels of several proinflammatory proteins, including both C-reactive protein (CRP) and interleukin-6 (IL-6), are often reported to be low when compared to American and European populations. This analysis determined if blood levels of CRP and IL-6 were associated with 4 cultural practices reflective of Japanese behavior and customs -- drinking tea, eating seafood, consuming vegetables, and partaking in relaxing baths regularly - among 382 adults living in Tokyo. Regression models controlled for demographic factors, adiposity (BMI), physical exercise, smoking, alcohol use, and chronic illness (e.g., diabetes). Consuming a Japanese diet was associated with significantly lower CRP and IL-6 levels. More frequent bathing was associated with lower IL-6, but not specifically predictive of low CRP. This study has confirmed prior evidence for low inflammatory activity in Japanese adults and its association with several behavioral practices common in Japan.

日本成年人的文化和生活方式与低炎症生理相关

日本是一个非常健康、长寿的东亚国家。此外，据报道，与美国和欧洲人群相比，包括 C 反应蛋白 (CRP) 和白细胞介素 6 (IL-6) 在内的几种促炎蛋白的典型水平较低。这项分析确定了居住在东京的 382 名成年人的血液 CRP 和 IL-6 水平是否与反映日本行为和习俗的 4 种文化习俗相关——喝茶、吃海鲜、吃蔬菜和定期泡澡。回归模型控制了人口因素、肥胖（BMI）、体育锻炼、吸烟、饮酒和慢性病（例如糖尿病）。日本饮食与显着降低的 CRP 和 IL-6 水平相关。更频繁的洗澡与较低的 IL-6 相关，但并不能明确预测较低的 CRP。这项研究证实了日本成年人炎症活动较低的先前证据，及其与日本常见的几种行为习惯的相关性。
