低碳水饮食可以预防流感

Trendy low-carb diets promoted by celebs protect against flu, a study suggests.

一项研究表明，名人倡导的时尚低碳水化合物饮食可以预防流感。

They activate a special type of immune cell which creates mucus in the lungs, researchers say.

研究人员说，它们可以激活一种特殊的免疫细胞，这种细胞会在肺部产生粘液。

This helps the body trap and kill the virus before it has a chance to cause severe illness. The research is a boost for low-carb keto diets which cut out bread, pasta and rice in favor of meat, fish and non-starchy veg. The findings were published in Science Immunology.

这有助于身体在病毒有机会引起严重疾病之前捕获并杀死病毒。这项研究促进了低碳水化合物的生酮饮食，少吃面包、意大利面和米饭，多吃肉、鱼和不含淀粉的蔬菜。研究结果发表在《免疫学》杂志上。

They have been promoted by stars including actress Gwyneth Paltrow and reality TV star Kim Kardashian.

他们得到了包括女演员格温妮丝·帕特洛和真人秀明星金·卡戴珊在内的明星的推广。

Scientists fed mice the keto diet and others standard grub. Fewer in the keto group died after being infected with flu. Analysis revealed the diet triggered the release of gamma delta T cells, which have not previously been linked to the virus.

科学家们给老鼠喂食了酮类食物和其他标准食物。酮组中死于流感的较少。分析显示，这种饮食触发了伽马-德尔塔T细胞的释放，而这些T细胞之前并没有被发现与病毒有关。

Mice bred without the gene that produced the cells had no protection from flu, even on a keto diet.

没有产生这种细胞的基因的老鼠，即使是吃酮类食物，也无法预防流感。

Researcher Prof Akiko Iwasaki, of Yale University, said: “This was a totally unexpected finding.

耶鲁大学研究员岩崎明子教授说:“这是一个完全出乎意料的发现。

“Harnessing the beneficial effects of a ketogenic diet through gamma delta T cells may offer a potential previously unrecognized avenue for influenza disease prevention and treatment.”

“通过γ- delta T细胞来利用生酮饮食的有益影响，可能为预防和治疗流感疾病提供一种以前未被认识到的潜在途径。”

Dr. Jenna Macciochi, from the University of Sussex, said: “There may be a thread of scientific truth to the old adage ‘feed a cold, starve a fever.’”

苏塞克斯大学的詹娜·马乔其博士说:“‘伤风时宜吃，发烧时宜饿’这句老话也许有一丝科学道理。”

Flu kills around 8,000 a year in England, official figures show.

官方数据显示，英国每年约有8000人死于流感。
