低碳水飲食可以預防流感

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

一項研究表明，名人倡導的時尚低碳水化合物飲食可以預防流感。

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

研究人員說，它們可以激活一種特殊的免疫細胞，這種細胞會在肺部產生粘液。

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.

這有助于身體在病毒有機會引起嚴重疾病之前捕獲并殺死病毒。這項研究促進了低碳水化合物的生酮飲食，少吃面包、意大利面和米飯，多吃肉、魚和不含淀粉的蔬菜。研究結果發(fā)表在《免疫學》雜志上。

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

他們得到了包括女演員格溫妮絲·帕特洛和真人秀明星金·卡戴珊在內的明星的推廣。

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.

科學家們給老鼠喂食了酮類食物和其他標準食物。酮組中死于流感的較少。分析顯示，這種飲食觸發(fā)了伽馬-德爾塔T細胞的釋放，而這些T細胞之前并沒有被發(fā)現(xiàn)與病毒有關。

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

沒有產生這種細胞的基因的老鼠，即使是吃酮類食物，也無法預防流感。

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

耶魯大學研究員巖崎明子教授說:“這是一個完全出乎意料的發(fā)現(xiàn)。

“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.”

“通過γ- delta T細胞來利用生酮飲食的有益影響，可能為預防和治療流感疾病提供一種以前未被認識到的潛在途徑。”

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.’”

蘇塞克斯大學的詹娜·馬喬其博士說:“‘傷風時宜吃，發(fā)燒時宜餓’這句老話也許有一絲科學道理。”

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

官方數(shù)據(jù)顯示，英國每年約有8000人死于流感。
