吃了抗生素或出了肠胃问题,很多人都会急着喝几杯益生菌,恢复肠道微生物的“自然平衡”。益生菌成为食品行业增长最快的1种产品,现已经融入酸奶、饮料和儿童食品中。然而,并非所有人都需要益生菌才能保持健康。1项对非洲狩猎采集者体内肠道细菌的新研究揭示,他们体内并没有大多数益生菌食品中的某种关键细菌成分,但仍能保持身体健康。这个世界上仅存的狩猎采集部落之——坦桑尼亚Hadza族人身上并没有西方国家现代饮食习惯所带来的结肠癌、结肠炎、克罗恩病或其他结肠疾病。
Ate antibiotics or stomach problems, many people will rush to drink a few cups of probiotics to restore intestinal microbial “natural balance.” Probiotics has become one of the fastest growing food products in the food industry and is now integrated into yogurt, beverages and children’s foods. However, not all people need probiotics to stay healthy. A new study of gut bacteria in African hunter-gatherers revealed that they do not have some of the key bacterial components in most probiotic foods in the body, but still maintain their health. The only remaining hunter-gatherer tribe in the world-the Hadza tribe in Tanzania-does not have colon cancer, colitis, Crohn’s disease or other colon diseases associated with modern eating habits in Western countries.
