Consumption of yoghurt and probiotics is associated with a reduced risk of sleep disorders

The research article entitled ‘Association between yogurt and dietary supplements containing probiotic consumption with sleep disturbance in US adults: Results from NHANES, 2009-2018’ explores the relationship between consumption of yogurt and dietary supplements containing probiotics and sleep disturbance in US adults.

Sleep disorders are a common public health problem, affecting a large proportion of the world's population. The gut microbiome, which plays a crucial role in brain homeostasis via the microbiota-gut-brain axis, is increasingly recognised for its involvement in sleep disorders. Probiotics, as living micro-organisms found in fermented dairy products such as yoghurt, have been shown to have potential beneficial effects on sleep quality.
