Have you ever experienced difficulty sleeping after a late-night snack? Yup, I’ve been there too. Unfortunately, there are some foods that can negatively impact your sleep.
The connection between your dinner plate and your dreams runs deeper than you might think. While it’s common knowledge that having a cup of coffee after dinner might keep you up, the impact of your overall diet on sleep quality is something many researchers are examining
Recent studies are showing surprising links between our daily eating habits and the quality of our nightly rest. In the United States, where sleep disorders and poor dietary choices are both widespread, scientists are beginning to connect the dots between these two public health concerns.
In this article, we will dive deeper and learn more about how your diet can impact your sleep.

Are There Foods That Can Improve Your Sleep?
Research suggests that certain foods may improve sleep quality. Studies have shown promising results for kiwis and tart cherries in particular.
A Taiwanese study found that participants who ate two kiwis an hour before bedtime for four weeks fell asleep 14 minutes faster and slept 40 minutes longer than those who didn’t.
Similarly, a UK study reported that individuals consuming 8 ounces of tart cherry juice twice daily experienced longer and more efficient sleep compared to those drinking a placebo.
Researchers relate these benefits to the presence of melatonin, a sleep-regulating hormone, in both kiwis and tart cherries. While the exact mechanism remains unclear, scientists speculate that consuming melatonin-rich foods might boost the body’s melatonin levels, which may improve sleep.
Other melatonin-containing foods, such as certain dairy products, may also promote better sleep. However, experts caution that more research is needed to establish definitive links between dietary melatonin and improved sleep quality.
Diet Factors That Might Affect Your Sleep
Sleep and diet are intricately connected with what we eat and when we eat. Many people underestimate the impact of their dietary choices on their nightly rest, focusing solely on obvious culprits like late-night caffeine. However, the relationship between food and sleep goes much deeper.
1. Impact of irregular mealtimes on sleep
Consistent meal timings play a crucial role in maintaining good sleep patterns. Irregular eating habits can disrupt the body’s internal clock or circadian rhythm, leading to sleep disturbances.
Experts who have extensive knowledge of sleeping recommend maintaining consistent mealtimes to support healthy sleep cycles.
2. Nutrient deficiencies and sleep quality
A diet lacking essential nutrients may negatively affect sleep.
Studies show a correlation between poor sleep and lower intake of calcium, magnesium, and vitamins C, D, E, and K, especially in older adults.
While the exact relationship is unclear, a balanced diet rich in these nutrients may support better sleep.
3. Gut Health and Sleep
Research suggests that a diverse gut microbiome may improve sleep for some individuals.
Experts recommend consuming a variety of plant-based foods, high-fiber items, and probiotics to support gut health, which may, in turn, benefit sleep quality.
Foods and Eating Habits That May Disrupt Sleep
Certain dietary choices can negatively impact sleep:
- Caffeine and alcohol consumption
- High-fat and high-sugar foods
- Diets low in fiber or tryptophan
- High-carbohydrate, low-fat diets
- Irregular meal patterns and late-night snacking
- Overeating close to bedtime
Nutrient-Rich Foods for Better Sleep
Tryptophan, an amino acid crucial for sleep regulation, is commonly found in meats, seeds, nuts, and soy products. Pumpkin seeds are particularly rich, containing 60% more tryptophan than turkey or chicken. Cherries and kiwis also offer sleep-promoting compounds.
B vitamins play a vital role in sleep hormone regulation. Vitamin B12, found in animal products and fortified foods, aids melatonin secretion. Vitamin B6, essential for serotonin production, is present in organ meats, starchy vegetables, and fortified cereals.
Foods that may enhance sleep include:
- Whole grains and beans
- Vegetables
- Fatty fish (salmon, tuna, sardines)
- Poultry and eggs
- Pumpkin seeds
- Kiwi fruit
- Tart cherry juice and cherries
- Milk and cheese
Does Meal Timing Matter?
Meal timing significantly impacts sleep quality. Large meals before bedtime can cause discomfort and disrupt sleep. Health experts advise finishing meals two to three hours before sleeping.
While simple carbohydrates consumed four hours before sleep might help you fall asleep faster, this isn’t a recommended long-term strategy. Studies show that high-sugar and high-carbohydrate diets often lead to poorer sleep.
For the best sleep, it’s not about specific foods but a balanced diet. A diet that includes the right amount of carbohydrates, protein, and fat can support your overall sleep quality and duration.
