Pistachios are not only a popular snack but may also offer a potential benefit for people seeking better sleep. A US medical study suggests that eating pistachios may influence biological processes linked to sleep.
Researchers at Columbia University examined the potential effects of pistachio consumption on sleep. The study noted that pistachios contain tryptophan, phytomelatonin and other compounds associated with sleep-related biological processes.
How Pistachios May Affect Sleep
According to the supplied report, pistachios also contain magnesium and vitamin B6, nutrients involved in processes through which tryptophan is converted into serotonin and melatonin.
Melatonin is widely associated with the body’s sleep-wake cycle, and many people use melatonin supplements to support sleep.
The researchers found that pistachios may influence several biological functions connected with sleep. However, the study did not establish how much pistachios should be consumed to improve sleep.
Study Published in Nutrition Research Reviews
The findings were published in the journal Nutrition Research Reviews.
The researchers reportedly noted that consuming pistachios does not appear to cause harm and may provide broader nutritional benefits, although the supplied report does not establish pistachios as a treatment for sleep disorders.
Pistachios Provide Several Nutrients
Pistachios contain a range of nutrients that contribute to overall health. According to the supplied report, a 28-gram serving provides approximately 159 calories, 8 grams of carbohydrates, 3 grams of fibre, 6 grams of protein and 13 grams of fat.
The serving also contains potassium, phosphorus, vitamin B6, copper, vitamin B1 and manganese.
Vitamin B6 is highlighted in the report as an important nutrient involved in several bodily functions, including processes related to blood sugar regulation.
Health note: The supplied study suggests a possible relationship between pistachio consumption and sleep-related biological processes, but it does not establish a specific serving size or prove that pistachios can treat insomnia or other sleep disorders.
