Sugar ki lls probiotics leading to obesity and disease | 糖會殺死導致肥胖和疾病的有益腸道細菌益生菌

An animal study conducted by researchers at Columbia University in New York suggests that ingesting too much processed sugar from processed foods such as chocolate, cookies, ice cream, cakes increase risk of obesity and other diseases by killing good gut bacteria that help protect against obesity and disease.

The study in mice published in the journal Cell finds that  sugar can have a negative effect on the gut microbiome in which some good bacteria or probiotics influence our immune system.

Good bacteria, bad bacteria

Many bacteria live in the gut and are responsible for increasing certain immune cells, specifically so-called T helper cells, or Th17 cells .  In the current study, the researchers observed that these immune cells regulate fat absorption in he mice’s gut.

The researchers also found that a sugar-loaded diet promotes the growth of certain bacteria, which in turn kills the immune-boosting probiotics. As a result, more fat is absorbed in the study mice through the intestinal mucosa, and the mice eventually became not only overweight but also sick.

紐約哥倫比亞大學的研究人員進行的一項動物研究表明，從巧克力、餅乾、冰淇淋、蛋糕等加工食品中攝入過多加工糖會殺死有益於預防肥胖和肥胖的腸道細菌，從而增加肥胖和其他疾病的風險。疾病。

發表在《細胞》雜誌上的小鼠研究發現，糖會對腸道微生物群產生負面影響，其中一些有益細菌或益生菌會影響我們的免疫系統。

好細菌壞細菌

許多細菌生活在腸道中，負責增加某些免疫細胞，特別是所謂的 T 輔助細胞或 Th17 細胞。在目前的研究中，研究人員觀察到這些免疫細胞調節小鼠腸道中的脂肪吸收。

研究人員還發現，含糖飲食會促進某些細菌的生長，進而殺死增強免疫力的益生菌。結果，更多的脂肪通過腸黏膜被研究小鼠吸收，最終小鼠不僅超重而且生病。
