A healthy and diverse population of friendly gut bacteria can help improve digestion and relieve symptoms of irritable bowel syndrome. But probiotics (beneficial bacteria found in certain foods and supplements) only contain a few different strains of bacteria, hardly contributing to the diversity.
Fiber, on the other hand, has a direct impact on constipation. It can help stools move along more quickly. What’s more, fiber feeds the friendly gut bacteria so that they increase in number and kind. Fiber is found in vegetables, fruits, whole grains, and legumes.
健康、多样化丰富的有益肠道菌群，可以帮助改善消化功能并缓解肠易激综合征的症状。但是益生菌（添加到某些食物和补充剂中的有益细菌）仅包含几种不同的菌株，对肠道菌群多样性几乎没有任何帮助。
而另一方面，纤维对便秘有着直接的影响。纤维可以帮助大便在肠道内更快地移动。更重要的是，纤维为有益的肠道细菌提供养分，有助于数量和种类的增加。纤维存在于蔬菜、水果、全谷物食品以及豆类中。
益生菌是用来促进消化系统健康的活细菌
它们有可能在体内进化，并且变成对人体有害的细菌。研究显示，某些益生菌会攻击肠道保护膜，并增加罹患肠躁症候群等疾病的风险。不健康的「垃圾」食物，即不含纤维的饮食方式，会增加益生菌变成有害细菌的机率。富含纤维的饮食，可促进肠道细菌的多样性，为身体提供保护作用。
Probiotics are living bacteria taken to promote digestive health. They have the potential to evolve once inside the body and become harmful. Research has shown how some probiotics can attack the protective coating of the intestine and increase the risk of conditions such as irritable bowel syndrome. Unhealthy “junk” food diets with no fiber boost the chance of probiotics undergoing harmful changes. High-fiber diets, which promote gut bacteria diversity, are protective.
Note:
Probiotics are live microorganisms that provide health benefits when consumed, including enhancement of gut epithelial barrier function, blocking of pathogen binding, and vitamin synthesis. There has been increasing success in expanding the therapeutic scope and efficacy of probiotics through genetic engineering, with prior work demonstrating preclinical efficacy against infectious and metabolic diseases.
