Walnut Consumption May Improve Sleep Quality in Young Adults
Imagine you're having trouble sleeping.
This study looked at whether eating walnuts could help.
Researchers gave young adults a handful of walnuts with dinner every day for two months.
They found that those who ate walnuts fell asleep faster and slept better overall.
Walnuts contain nutrients like melatonin, tryptophan, magnesium, and B vitamins that may support better sleep.
This suggests that walnuts might be a simple, food-based way to improve sleep, though more research is needed to confirm these findings.
A study found that eating walnuts daily may improve sleep quality.
The study involved 76 young adults consuming walnuts with dinner.
Walnut consumption increased melatonin levels in participants.
Participants fell asleep faster and reported less daytime sleepiness.
Researchers suggest walnuts may support healthy sleep due to their nutrients.
