Sleep & Pumpkin Seeds – Expert Opinions

Above we said, ” According to studies and medical experts; eating pumpkin seeds before bed can help promote sleep”.

Firstly, let’s find out what medical experts have said about the relationship between pumpkin seeds and sleep. Then, we will analyse the related studies.

Food can be a strong support in the quest for a good night’s sleep, — Trouble staying asleep? Try pumpkin seed or pumpkin seed powder as a solution, — Those who cannot stay asleep and wake throughout the night are typically low in serotonin, — And, pumpkin seeds are rich in tryptophan that the body uses to make serotonin,– said Dr Pina LoGiudice – co-founder and director of InnerSource Natural Health and Acupuncture – in an article published on doctoroz.com (4),(5).

Pumpkin seeds are rich in magnesium and tryptophan, which has been helpful in treating insomnia. The human body converts tryptophan into serotonin, then melatonin, the relaxing sleep hormone,” said Tracee Yablon Brenner – a registered dietitian nutritionist and trained culinary professional – who talked to Food Network (6),(7).

Pumpkin Seeds and Better Sleep

Potassium, tryptophan and zinc. These are the nutrients making pumpkin seeds an ideal late-night snack for those who want to get a good night’s sleep.

So, how do these nutrients affect sleep? What do they do in the body and induce sleep?

In this section, we will scientifically explain the role of each of these nutrients in sleep. Please keep on reading…

 

1-) Tryptophan in Pumpkin Seeds Promote Sleep

It is safe to say that the main reason pumpkin seeds are associated with better sleep is that they contain a substantial amount of tryptophan.

Tryptophan is an essential amino acid that cannot be produced by the human body. So, it has to be taken from animal and plant food sources, according to WebMD (10).

If you often feel sleepy or relaxed after consuming certain foods such as turkey, kiwi or milk, this is mainly because they contain a considerable amount of tryptophan (11),(12),(13).

 

How Does Tryptophan Promote Sleep?

Firstly, it is important to say that tryptophan doesn’t directly affect your sleep. It rather starts the process.

Tryptophan is required for the production of serotonin and melatonin hormones (14),(15). Both of these hormones, especially melatonin play a crucial role in sleep. 

 

Seratonin

According to different reports and medical articles; while serotonin is exactly involved in wakefulness, it may also contribute to sleep by relaxing the body (16),(17),(18),(19).

However, one thing is certain about serotonin! It is necessary for the production of melatonin (19),(20).

 

Melatonin

The human body uses tryptophan to produce serotonin, then uses serotonin to produce melatonin. Shortly, tryptophan > serotonin > melatonin (21).

In the evening melatonin production starts rising and it is released into the bloodstream and reaches all body tissues, thereby, promoting sleep (22).

Melatonin puts you into a state of quiet wakefulness that helps induce sleep,” says Johns Hopkins sleep expert Luis F. Buenaver (23),(24).

 

How much tryptophan for sleep?

According to multiple studies, consuming 1 to 2 mg of L-tryptophan each night over several nights can significantly improve sleep quality and quantity (28),(29).

According to the USDA Food Composition Database, 100 gr pumpkin seeds have 0.58 g tryptophan (30).

 

Summary

The conclusion is, in order for both melatonin and serotonin to be produced in the body, tryptophan is necessary.

It bears repeating, the human body can’t produce tryptophan, therefore, has to be taken through the diet.

This is why tryptophan-containing foods such as kiwi, turkey, almond milk and pumpkin seeds are heavily associated with better sleep.

 

2-) Zinc in Pumpkin Seeds May Aid Sleep

After iron, zinc is the second most abundant trace mineral in the human body and has many roles (31),(32).

Growing evidence tell us that zinc may also have sleep-inducing properties.

Let’s look at a couple of these studies.

 

Zinc Supplementation Improved Sleep Quality – Study Found

In one study, researchers aimed to evaluate the impact of zinc supplementation on the sleep quality of intensive care unit (ICU) nurses.

One group were given zinc tablets while others were given a placebo. After a month, researchers assessed the sleep quality of ICU nurses.

It was found that the zinc-supplementing group of nurses slept better compared to the nurses in the placebo group.

 

Zinc Deficiency May Lead Insomnia – Study Suggests

In one review of studies on zinc and sleep, researchers aimed to examine the potential role of zinc in sleep.

A survey – carried out by the National Health and Nutrition Examination – revealed that people who sleep less than 5 hours a night were found to consume less zinc than those who sleep 7 to 9 hours a night.

In the review, researchers also cited other studies and articles, showing the potential relationship between sufficient zinc intake and reduced sleep problems.

Researchers concluded; more research is needed to understand the mechanism of how zinc aids sleep; however, zinc appears to have a role in regulating circadian rhythm and inducing sleep (33).

 

Zinc Helps Convert Tryptophan to serotonin – Healthline Says

According to Healthline; zinc – which is found in great quantities in pumpkin seeds – help convert tryptophan to serotonin (34).

And, as we discussed in detail above, serotonin is the precursor of melatonin, the sleep-inducing hormone.

 

How Much Zinc is Available in Pumpkin Seeds?

Pumpkin seeds are an excellent source of zinc. It is suggested that 100 g of pumpkins seeds contain around 8 mg of zinc (35),(36).

The recommended daily intake of zinc is 8 mg for women 11 mg for men (37),(38).

 

Summary

Although it may not be direct, zinc appears to impact sleep quality. So, it should be safe to suggest that the high amount of zinc in pumpkin seeds may contribute to sleep quality.

 

3-) Magnesium in Pumpkin Seeds Help Sleep

It is reported that up to 80 per cent of Americans do not consume enough magnesium, leading to a high number of magnesium-deficient people in the country (39),(40),(41).

What’s obvious is, magnesium deficiency can lead to serious medical conditions if left untreated.

It is suggested that consuming less magnesium the body needs can also cause various sleep problems (42),(43).

So, if you live in the USA or other countries where the western diet prevails, then you, too, might be lacking magnesium and suffer from insomnia as a result.

If that is the case pumpkin seeds can help because they are one of the most magnesium-dense natural foods.

 

How Does Magnesium Help Sleep? 

When experiencing too much stress, getting a good night’s sleep is not easy at all. Good sleep requires the body and brain to be relaxed and stress-free. Essentially, this is where magnesium comes in handy.

Studies and medical experts suggest that magnesium help sleep longer by relaxing the body and reducing stress (44),(45).

In addition to its relaxing feature, magnesium also regulates the melatonin hormone (46).

What’s more, it is claimed that having an optimal level of magnesium in the body can reduce the symptoms of restless legs syndrome, a condition that can severely hinder sleep quality (47),(48).

 

How Much Magnesium Available In Pumpkin Seeds? 

It bears repeating, pumpkin seeds are one of the most magnesium-dense natural foods.

According to Medical News Today; A 100-gram (g) serving of pumpkin seeds can contain over 90 mg of magnesium (49).

Please note that a healthy adult man requires around 400 mg magnesium intake while a healthy adult woman requires around 310 mg of magnesium (50).

That is to say; 100 gr of pumpkin seeds can meet almost one-third of your daily magnesium need.

 

Summary

With their high magnesium content, pumpkin seeds can help your body relax, which in turn, may help you sleep better.

 

Final Verdict

Multiple studies have reported that a lot of people around the world suffer from various sleep problems (50),(51),(52).

However, since sleeping medications associated with some side effects, many people seek natural solutions (foods) for their sleep problems.

In this article, we have discussed one of these natural solutions for insomnia; Pumpkin seeds

With their potassium, tryptophan and zinc content, pumpkin seeds can help you get a good night’s sleep. And, we profoundly explained how these particular nutrients positively impact sleep. 

Certain foods like pumpkin seeds, kiwi fruit, almond milk or chamomile tea may improve sleep especially when consumed before bed.

Having said that, if you suffer from a sleep problem for an extended period of time, we strongly recommend you work with your doctor to find the underlying cause and get the best treatment possible.
