A PB&J sandwich before bed may help you sleep better at night

Actually, eating a peanut butter and jelly sandwich with whole wheat bread and high-quality, sugar-free jelly at dinner may have beneficial effects on sleep onset, quality, and duration!


Above all, a peanut butter and jelly sandwich before bed may support a good night’s sleep because it’s an excellent dietary source of tryptophan.

This amino acid play a key role in the production of the neurotransmitter serotonin. Serotonin is involved in regulating mood, and sleep. High tryptophan intake may be beneficial for improving sleep latency and obstructive sleep apnea![1]

A good night's sleep and weight loss can be aided by consuming a peanut butter and jelly sandwich a few hours before bed, but make sure to use sugar-free, high-quality jelly, and whole wheat bread.Pin

Furthermore, tryptophan is involved in the synthesis of melatonin. This hormone is the internal clock of the body. It regulates sleep! We can skyrocket melatonin levels in the body by consuming foods naturally high in melatonin.[2]

A PB&J sandwich has about 100 mg of tryptophan. This dose is 23% of the Daily Value:

  • peanut butter has 229 mg of tryptophan per 100g. A tablespoon has about 37 mg of tryptophan. This dose is almost 9% of the recommended daily intake.
  • bread has some tryptophan as well. Most breads have between 90 and 120 mg of tryptophan per 100g. A medium slice has about 30 mg of tryptophan.

Another great snack that supports a good night’s sleep, as it’s particularly high in tryptophan, is turkey sandwich.

Moreover, tryptophan is necessary for the synthesis of niacin.


Additionally, a PB&J sandwich may improve sleep quality and onset because it’s high in niacin. A PB&J sandwich has approximately 4.73 mg of niacin. This dose is 30% of the recommended daily intake! Actually:

  • peanut butter is the vegan food with the highest niacin content per serving! Just a tablespoon provides about 13% of the Daily Value!
  • bread has about 4.8 mg of niacin per 100g. A slice provides 1.3 mg of niacin. This dose is 8% of the DV.

High niacin intake has been linked to sleepiness. It seems beneficial to consume foods high in niacin at dinner. Niacin and magnesium relax muscles.[3]


Furthermore, a PB&J sandwich before bed may have beneficial effects on sleep because it’s a great dietary source of magnesium. A PB&J sandwich has about 85 mg of magnesium. This dose is 20% of the Daily Value!

  • peanut butter has about 193 mg of magnesium per 100g. A tablespoon has about 33 mg of magnesium, or almost 8% of the Daily Value.
  • bread also has some magnesium. White bread has only 27 mg of magnesium per 100g, while whole wheat bread has 77 mg of magnesium per 100g. A slice of whole wheat bread has 25 mg of magnesium, or 6% of the DV.[4]

Adequate amounts of magnesium may improve sleep onset latency, early morning awakening, snoring, sleep duration, and daytime falling asleep. Especially in elderly people.[5,6]

Vitamin E

In addition, a PB&J sandwich at dinner may be beneficial for a good night’s sleep because it’s high in vitamin E. A PB&J sandwich has about 2.4 mg of vitamin E. This dose is 16% of the DV.

  • peanut butter has about 5.4 mg of vitamin E per 100g, or 0.86 mg of vitamin E per tablespoon.
  • whole wheat bread has about 2.8 mg of vitamin E per 100g, or 0.76 mg per slice. White bread has negligible amounts of vitamin E, though.

Vitamin E may play a role in sleep disorders because it has a potent antioxidant activity. Vitamin E has a protective effect on sleep quality.[7]


Most noteworthy, a PB&J sandwich before bed is good for you because it’s one of the few foods high in resveratrol. A PB&J sandwich with high-quality jam made of berries has even more resveratrol.

To support healthy weight management and better sleep, it is recommended to consume a peanut butter and jelly sandwich a few hours before bedtime, using only high-quality, sugar-free jelly, and whole wheat bread.Pin

Resveratrol is a powerful polyphenol which is naturally present only in peanuts, berries, grapes, and red wine.

Eat PB&J sandwich with high-quality, sugar-free jelly & whole grain bread

However, a typical peanut butter and jelly sandwich may not be the best late night snack because it’s particularly high in sugar.

Too much sugar at night may lead to poor sleep quality and frequent arousal. Especially if we eat a carbohydrate-rich meal just one hour before bed. It’s beneficial to avoid foods with added sugar 4 hours before bedtime.[9]

Most common, cheap jellies and jams are high in sugar, though. Eat only jams and jellies low in sugar for a good night’s sleep.

Actually, there are jams, jellies, or marmalades with no added sugar. Natural, low-glycemic sugar substitutes, such as monk fruit or stevia are used, instead. In fact, the top 4 bestseller jams on Amazon have no added sugar.

Eating reasonable amounts of sugar-free jams or jellies a day is also good for weight loss.

In addition, you should prefer eating a PB&J sandwich with whole wheat bread. White bread spikes blood sugar levels. It has a very high glycemic index, as it has too much sugar! On the contrary, whole grain bread is good for you, as it’s packed with fiber, minerals, and vitamins.

After all, diets higher in fiber and healthy fats are associated with better sleep quality. Peanut butter is one of the richest foods in monounsaturated fats.[10]

When consumed in moderation and when replace saturated fat, monounsaturated fats have a beneficial effect on the heart.[11]

A PB&J sandwich is high in fiber as well. Especially if it’s made of whole grain bread and a high-quality jelly.


Moreover, a PB&J sandwich with brown bread and sugar-free jelly can be a great snack before bed because it’s high in protein. Diets high in protein are associated with better sleep quality.[12]
