Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Walnut (Juglans regia) has been used traditionally in some cultures as a food believed to support general health, but its specific use to treat or support insomnia primarily stems from traditional or anecdotal claims rather than robust scientific evidence. Walnuts are a source of melatonin, the hormone that helps regulate sleep-wake cycles, and contain other nutrients such as magnesium and polyunsaturated fatty acids, which have some general associations with improved sleep quality. However, direct clinical studies demonstrating that walnut consumption has a meaningful, reliable effect on insomnia are lacking.

Historical and folk medicine records indicate that walnuts have been consumed as a night-time snack in certain traditional practices, justified by their perceived calming and sleep-promoting effects. Scientific research does show that walnuts contain measurable amounts of melatonin, and a small number of animal and pilot human studies have examined the effect of walnut supplementation on sleep parameters. These studies are limited in size and scope and do not conclusively show that walnut consumption is an effective treatment for insomnia. As such, while there is a plausible basis for the traditional use of walnuts in supporting sleep, the evidence remains weak and largely anecdotal.

In summary, the use of walnut to support or treat insomnia is primarily supported by traditional beliefs and limited, inconclusive scientific data. More rigorous human clinical trials would be necessary to establish efficacy for this indication.
