BMJ: 膳食脂肪的质量和遗传风险对2型糖尿病发病率的影响

2019-09-13 不详 MedSci原创

本项研究旨在探讨2型糖尿病的遗传负荷是否改变了膳食脂肪质量与2型糖尿病发病率的关系。

背景及目的:
本项研究旨在探讨2型糖尿病的遗传负荷是否改变了膳食脂肪质量与2型糖尿病发病率的关系。

方法:
研究人员收集了1970年1月至2017年2月期间的所有人群的全基因组遗传数据以及关于膳食脂肪质量和欧洲血统参与者2型糖尿病发病率的信息。对2型糖尿病遗传风险特征进行了68个变异的多基因风险评分,通过使用经验证的群组特异性饮食评估工具记录饮食。主要观察结果是2型糖尿病的总体调整风险比率,以及脂肪类型与多基因风险评分的相互作用。

结果:
本项研究共纳入102305名参与者中,共记录了 20015例2型糖尿病病例的发生。每10个风险等位基因增量2型糖尿病中的多基因风险分数的危险比为1.64(95%置信区间1.54至1.75)。多不饱和脂肪和总ω-6多不饱和脂肪摄入量代替碳水化合物的增加与2型糖尿病的风险较低(危险比:0.90;95%CI:0.82?0.98)和(危险比:0.99;95%CI:0.97?1.00)。代替碳水化合物的增加的单不饱和脂肪与2型糖尿病的高风险相关联(危害比1.10,95%置信区间1.01至1.19)。未观察到膳食脂肪和多基因风险评分对2型糖尿病风险(相互作用P> 0.05)之间的显着相互作用。

结论:
本项研究表明遗传负担和膳食脂肪的质量都与2型糖尿病的发病率有关。

Clin Translational Gastroenterology: 增加膳食纤维摄入可以改变食管微生物群

越来越多的证据表明某些微生物组分会影响食管疾病。饮食,尤其是纤维和脂肪的摄入,是结肠微生物组的有效改良剂,因此,本项研究假设膳食纤维和脂肪摄入量与独特的食管微生物组有关,并对此进行了研究。

Inflamm Bowel Dis:膳食铁与血红素铁的消耗与炎症性肠病发生率的关系

膳食铁与血红素铁可以通过对患者肠道共生菌和肠屏障功能的影响来调节结肠炎症,但是膳食摄取铁总量和血红素铁对于克罗恩病(CD)与溃疡性结肠炎(UC)发病率之间的关系还没有研究报道。

Clinical Nutrition:健康的饮食模式及其相应的肠道微生物群特征与2型糖尿病风险较低有关

糖尿病前期和老年人都是发生二型糖尿病(T2D)的高危因素,而肥胖是引发该疾病的最重要因素之一。营养干预是预防T2D的最有效工具,因为它可以促进/抑制肠道微生物群的增长。然而,到目前为止,没有具体的饮食建议来延缓老年人群中T2D的发展。因此,本项研究的目的是了解饮食模式对肥胖和非肥胖老年前驱糖尿病受试者的肠道微生物群特征的影响以及对T2D发生风险的影响。
