Pistachio Consumption for Insomnia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if eating pistachios can improve sleep quality in individuals with sleep problems. Researchers are testing whether pistachios, which contain compounds that might aid sleep, are more effective than a control food like muffins and cookies. Ideal candidates for the trial are middle-aged adults who have trouble sleeping but do not have chronic diseases, excessive caffeine consumption, or conditions like sleep apnea. Participants should also be willing to stop taking vitamin supplements and avoid time zone travel during the study. As an unphased trial, this study offers participants the chance to contribute to groundbreaking research on natural sleep aids.
Do I have to stop taking my current medications for the trial?
The trial requires participants to stop using medications that influence CYP1A2 and selective serotonin reuptake inhibitors. If you are taking these types of medications, you would need to discontinue them to participate.
Is there any evidence suggesting that pistachio consumption is likely to be safe for humans?
Research has shown that eating pistachios might help improve sleep. One study found that consuming 57 grams of pistachios as a nighttime snack was easy to digest and did not negatively affect blood sugar or blood pressure. Another study found that pistachios might even help lower blood pressure at night.
Additionally, older adults who eat pistachios seem to feel less anxious, suggesting calming effects. These findings indicate that pistachios are generally safe and may offer benefits for sleep and overall health.12345Why are researchers excited about this trial?
Researchers are excited about using pistachios to treat insomnia because pistachios are a natural source of melatonin, a hormone that helps regulate sleep. Unlike typical insomnia treatments like prescription medications or over-the-counter sleep aids, pistachios offer a dietary approach that might have fewer side effects. Additionally, pistachios are packed with nutrients, including magnesium and vitamin B6, which also support healthy sleep patterns. This makes pistachios a potentially effective and holistic option for those struggling with sleep issues.
What evidence suggests that pistachio consumption might be an effective treatment for insomnia?
Research shows that pistachios are rich in compounds that aid sleep, including phytomelatonin, a natural form of melatonin found in plants. Melatonin is a hormone that regulates sleep-wake cycles. Some studies have found that certain pistachios contain up to 223 micrograms of phytomelatonin per gram. Although eating pistachios doesn't significantly alter melatonin levels in saliva, their high phytomelatonin content suggests they might improve sleep. Additionally, some observational studies have linked increased nut consumption with better sleep quality. This trial will compare pistachio consumption with a control group receiving muffins and cookies to evaluate their potential impact on sleep improvement. While direct studies on pistachios and sleep improvement are lacking, these findings suggest pistachios could naturally help with sleep issues.13678

What Are the Treatments Tested in This Trial?
Interventions
- Pistachio
Trial Overview
The study aims to see if eating pistachios can help people sleep better compared to a control food, which doesn't contain sleep-promoting compounds. It's a randomized controlled trial, meaning participants will be randomly assigned to one of the two groups.
How Is the Trial Designed?
2
Treatment groups
Active Control
Placebo Group
During the experimental (pistachio) intervention period, participants will be given 2 servings of pistachios (28 g each) to consume once in the morning (within 3 hours of wake time) and once in the evening (3-6 hours before bedtime) every day.
During the control food intervention period, participants will be given muffins and cookies (one serving each/day) to be consumed once in the morning (within 3 hours of wake time) and once in the evening (3-6 hours before bedtime) every day.
