Feeling restless at night? What you eat might be the key to unlocking a good night’s sleep. Certain foods contain nutrients and compounds that can naturally promote relaxation and improve sleep quality. This guide explores the best foods to help you fall asleep, backed by scientific research and expert insights.
Why Food Choices Matter for Sleep
The connection between food and sleep is undeniable. Just as coffee can keep you awake, certain foods can encourage drowsiness and relaxation. This isn’t just about feeling full; it’s about the specific nutrients and compounds in food that interact with your body’s sleep-wake cycle.
However, the nutrient profile can vary significantly among different cultivars and growing conditions. Red grapes, for example, can have high melatonin levels in some varieties, while others contain virtually none.
Diet plays a significant role in overall health, impacting weight, cardiovascular health, and blood sugar levels. Consulting a doctor or dietitian is crucial before making major dietary changes to ensure these choices support sleep and overall well-being. A balanced diet can often support better sleep.
Top Foods to Promote Sleep
Let’s delve into specific foods that have been shown to aid sleep:
Kiwi
This small, flavorful fruit, known for its vibrant green flesh, boasts an impressive nutritional profile. Rich in vitamins C and E, potassium, and folate, kiwis offer a range of health benefits, including improved sleep.
Research suggests that eating kiwi before bed can significantly improve sleep quality. A study found that individuals who consumed two kiwis an hour before bedtime fell asleep faster, slept longer, and experienced enhanced sleep quality.
The sleep-promoting effects of kiwis are attributed to their antioxidant properties, ability to address folate deficiencies, and high concentration of serotonin, a neurotransmitter that plays a crucial role in regulating sleep.
Tart Cherries
Unlike their sweeter counterparts, tart cherries offer a distinctively sour flavor. These cherries, often enjoyed whole or as a juice, have been linked to improved sleep in multiple studies.
Studies have demonstrated that drinking tart cherry juice can lead to increased total sleep time and improved sleep efficiency, especially in individuals with insomnia.
The high melatonin content of tart cherries is believed to be responsible for these benefits. Melatonin helps regulate the circadian rhythm, promoting healthy sleep patterns. Additionally, the antioxidant properties of tart cherries may contribute to their sleep-enhancing effects.
Malted Milk
Malted milk, a blend of milk and a powder containing wheat flour, malted wheat, and malted barley, has been a popular bedtime drink for generations.
While the exact mechanisms are not fully understood, studies suggest that malted milk can reduce sleep interruptions. This may be due to the presence of B and D vitamins, phosphorus, zinc, and magnesium, which can promote relaxation. Furthermore, milk contains melatonin, and milk harvested at night has higher melatonin levels, potentially enhancing its sleep-inducing properties.
Fatty Fish
Incorporating fatty fish into your diet may lead to better sleep. A study found that consuming salmon three times a week resulted in improved overall sleep and enhanced daytime functioning.
The benefits of fatty fish are attributed to their high vitamin D and omega-3 fatty acid content. These nutrients play a role in the release and regulation of serotonin, a neurotransmitter essential for sleep. The study particularly highlighted the benefits of fish consumption during winter when vitamin D levels tend to be lower.
Nuts
Almonds, walnuts, pistachios, and cashews are often recommended as sleep-friendly snacks. These nuts contain melatonin, omega-3 fatty acids, magnesium, and zinc, all of which can contribute to better sleep.
Clinical trials have shown that a combination of melatonin, magnesium, and zinc can help older adults with insomnia sleep longer and more deeply.
Rice
While research on carbohydrate intake and sleep is varied, some evidence suggests that rice consumption can improve sleep.
A study conducted in Japan found that individuals who regularly consumed rice reported better sleep compared to those who ate more bread or noodles. While this study only showed an association, it aligns with previous research indicating that consuming foods with a high glycemic index around four hours before bedtime can help with falling asleep.
It’s important to note that not all carbohydrates are created equal. Sugary beverages and sweets have been linked to worse sleep, suggesting that the type of carbohydrate and what it’s consumed with can impact its effect on sleep. Combining carbohydrates with tryptophan-rich protein may facilitate tryptophan’s access to the brain, promoting sleep.
The Bigger Picture: Diet, Sleep Hygiene, and Overall Wellness
While incorporating these foods into your diet can be beneficial, it’s crucial to focus on overall healthy eating patterns and sleep habits. As many as 35% of American adults experience insomnia symptoms, so leveraging food and drinks for better sleep is a worthwhile endeavor.
Prioritizing a balanced diet rich in fruits and vegetables provides a stable source of essential vitamins and minerals, including those that promote sleep. The Mediterranean Diet, for example, has been associated with both heart health and improved sleep.
Good sleep hygiene plays a crucial role in your ability to sleep well. Ensuring a comfortable sleep environment with the right mattress, pillows, and decor is essential.

While sleep-promoting foods can be helpful, they may be less effective if you have poor sleep hygiene. Addressing factors like noise, light exposure, and electronic device use in bed is crucial for optimizing sleep.
By reviewing your sleep hygiene practices and incorporating sleep-friendly foods into your diet, you can create a comprehensive plan to achieve more consistent and replenishing rest.
