Pistachios could contribute to improving sleep quality, according to a scientific review published last September in the journal Nutrition Research Reviews.
Researchers analyzed studies on the nutrients and bioactive components of this nut and their potential effects on sleep.
Pistachios contain vitamin B6, tryptophan, magnesium, fiber, polyphenols, and phytomelatonin. Each of these components could influence sleep by promoting melatonin production, altering gut bacteria, and affecting gut-brain communication.
Researchers consider pistachios a promising food for studying potential nutritional strategies aimed at improving sleep.
However, they caution that clinical trials in humans are still needed to determine whether consuming them leads to direct improvements in sleep duration and quality.
