饮食脂肪量增加非霍奇金淋巴瘤风险

二〇一七年八月二号星期三(健康中心 JKZX.com)– 高脂肪饮食 (high fat diet)在西方很常见,该饮食被认为对一些西方疾病如心脏病,糖尿病,自身免疫性疾病和癌症如非霍奇金淋巴瘤(non-Hodgkin’s lymphoma)等疾病负有责任。

今年发表在“营养与癌症”杂志上的一项新研究表明,食用太多的脂肪特别是动物脂肪可能会增加一些特定类型的淋巴瘤,如非霍奇金淋巴瘤。

以前的研究暗示高脂饮食涉可能是非霍奇金淋巴瘤(NHL)的病因之一。但研究结果并不一致。

现今这个研究回顾了221篇发表的研究和病例对照研究,并分析了来自其中10份报告的数据,该分析确认总的饮食脂肪量与非霍奇金淋巴瘤风险增加26%相关。

就非霍奇金淋巴瘤种类具体说来,高脂肪摄入增加扩散性大B细胞淋巴瘤风险41%,滤泡淋巴瘤风险21%,T细胞淋巴瘤风险12%。 相比之下,高膳食脂肪与小淋巴细胞淋巴瘤/慢性淋巴细胞性白血病无关。

该研究得出结论:“总脂肪消耗,特别是动物脂肪,增加NHL(非霍奇金淋巴瘤)的风险”。

Dietary fat raises risk for Non-Hodgkin’s lymphoma

Wednesday Aug 2, 2017 (JKZX.com) — High fat diet is commonly used in the West, which some claim is responsible for Western diseases like heart disease, diabetes, autoimmune diseases and cancers such as non-Hodgkin’s lymphoma.

A new study published in Nutrition and Cancer this year suggests that eating too much dietary fat particularly animal fat can increase some specific types of lymphoma like non-Hodgkin’s lymphoma.

Previous studies hint high-fat diets are implicated in the etiology of non-Hodgkin’s lymphoma (NHL). But the results were inconsistent.

The study reviewed 221 published cohort and case-control studies and analyzed data from 10 out them only to confirm that the total fat consumption was linked to 26% increased risk for non-Hodgkin’s lymphoma.

Specifically, high fat intake was correlated with 41% increased diffuse large B-cell lymphoma and 21% increased risk for follicular lymphoma and only marginally associated with T cell lymphoma (12%). In contrast, high dietary fat was not associated with small lymphocytic lymphoma/chronic lymphocytic leukemia.

The study concluded “Total fat consumption, particularly animal fat, increases the risk for NHL (non-Hodgkin’s lymphoma)”.

The study was conducted by Tian-Jie Han at Shandong University in China and colleagues. (David Liu)
