This diversity is crucial for a balanced gut environment, which in turn supports digestion and immune function. Furthermore, kefir contains tryptophan, an amino acid that promotes relaxation and improves sleep quality. By drinking kefir at night, you not only introduce beneficial bacteria to your gut but also support restful sleep, creating a symbiotic relationship between gut health and sleep quality.

Additionally, bananas contain magnesium and potassium, which help relax muscles and nerves, preparing the body for sleep. The fruit's high tryptophan content also supports serotonin production, a precursor to the sleep hormone melatonin. Consuming a banana in the evening can thus act as a natural sleep aid while simultaneously nourishing gut bacteria, making it an ideal nighttime snack for those seeking to enhance gut health.
