Beef Jerky and Sleep: Does It Keep You Awake?

When hunger pangs hit late at night, reaching for a snack is a common recourse. Among the myriad of options, beef jerky might seem like a tempting choice due to its high protein content and savory flavor. However, if you've ever wondered whether beef jerky could impact your sleep or keep you awake, you're not alone. Let's explore the relationship between consuming beef jerky and its potential effects on sleep.

The Connection Between Beef Jerky and Sleep

High Protein Content

Beef jerky is indeed rich in protein, a nutrient known for its numerous health benefits, including muscle repair and growth. While protein is an essential part of any diet, consuming high amounts before bedtime can have mixed effects on sleep. Some studies suggest that protein can promote sleep by influencing the production of serotonin, a neurotransmitter that's converted into the sleep hormone melatonin. However, the digestive process for high-protein foods can be more taxing on the stomach, potentially causing discomfort that might make falling asleep more difficult for some people.

Sodium Levels

Beef jerky is also known for its high sodium content, used as both a flavor enhancer and a preservative. High sodium intake can lead to increased thirst and a greater need to urinate, which may disrupt sleep if you're waking up thirsty or needing to go to the bathroom during the night.

Tyramine Content

Another factor to consider is that beef jerky contains tyramine, an amino acid that can trigger the release of norepinephrine, a brain stimulant. Foods high in tyramine have been reported to cause insomnia or sleep disturbances in some individuals, as the stimulant effect can make it harder to fall asleep.

Caffeine and Other Additives

Some flavored varieties of beef jerky may contain added ingredients like caffeine or monosodium glutamate (MSG), which could potentially affect sleep. Caffeine, a known stimulant, can disrupt sleep patterns if consumed too close to bedtime. While less common, sensitivity to MSG could also impact sleep quality for some people.

Tips for Better Sleep

If you enjoy beef jerky and are concerned about its potential impact on your sleep, consider the following tips:

  • Timing Matters: Try to avoid eating beef jerky or other high-protein, high-sodium snacks right before bed. Giving your body a few hours to digest before lying down can help minimize any discomfort or sleep disturbances.
  • Stay Hydrated: If you do indulge in a salty snack like beef jerky, drinking plenty of water can help offset the increased thirst from the sodium content. Just be mindful not to drink too much right before bed to avoid nighttime trips to the bathroom.
  • Choose Wisely: Opt for beef jerky with lower sodium and no added caffeine or stimulants, especially if you're sensitive to these ingredients.


While beef jerky is a nutritious and protein-rich snack, its high sodium content and the presence of tyramine could potentially affect sleep for some individuals, especially if consumed close to bedtime. Understanding how your body reacts to different foods and being mindful of your dietary choices in the evening can help ensure that your late-night snacking doesn't interfere with a good night's rest.

Short Answer: Eating beef jerky before bed could potentially keep you awake, due to its high protein and sodium content, and the presence of tyramine, which may stimulate the brain. Additionally, additives like caffeine in some flavored jerky varieties could disrupt sleep. To minimize the risk of sleep disturbances, it's advisable to avoid consuming beef jerky right before bedtime, especially if you are sensitive to these ingredients.
