Microbiota inhabit nearly every part of our body with the gut microbiota representing the greatest density and absolute abundance. The gut-microbiota-brain axis facilitates bidirectional communication between gut microbiota and the brain. For instance, romantic relationship not only brings joy, it is also associated with increased gut microbiota diversity and health benefits whereas reduced microbiota diversity is related to obesity, cardiac disease, type 2 diabetes, and inflammatory disorders. Research has shown that dietary fibers may increase microbiota diversity and exert antidepressant effect. Among a plethora of life stressors, romantic relationship dissolution is a relatively common and painful experience that people encounter from time to time. Depressed mood, social isolation and poor intake are all associated with romantic relationship dissolution. In this article, it is hypothesized that romantic relationship dissolution is accompanied by decreased gut microbiota diversity which could be corrected with the ingestion of dietary fibers with an additional antidepressant benefit.
微生物群几乎存在于我们身体的每个部位，其中肠道微生物群的密度和绝对丰度最高。肠道-微生物群-脑轴促进了肠道微生物群与大脑之间的双向交流。例如，恋爱关系不仅能带来快乐，还与肠道微生物群多样性增加和健康益处相关，而微生物群多样性降低则与肥胖、心脏病、2型糖尿病和炎症性疾病有关。研究表明，膳食纤维可能会增加微生物群多样性并发挥抗抑郁作用。在众多生活压力源中，恋爱关系的结束是人们不时会遇到的一种相对常见且痛苦的经历。情绪低落、社交孤立和饮食不佳都与恋爱关系的结束有关。在本文中，我们假设恋爱关系的结束会伴随着肠道微生物群多样性的降低，而摄入膳食纤维可以纠正这种情况，并具有额外的抗抑郁益处。
