When it comes to better sleep, advice often focuses on bedtime routines and sleep hygiene—like setting your room to the perfect temperature or limiting screen time before bed. But did you know that what (and when) you eat can also have a major impact on your sleep quality? The good news? These nutrition tips for improving sleep are easy to incorporate into your routine and can make a significant difference.
1. Prioritize protein at dinner
The food you eat closest to bedtime can significantly influence your sleep. Research shows that diets low in protein (less than 16 percent of daily calories) are associated with poorer sleep quality. Surprisingly, this matches the average protein consumption in the U.S., meaning many people are missing the mark.
To combat this, aim for a minimum of 30 grams of protein per meal, though some may benefit from 40 to 50 grams. Protein slows digestion, which helps stabilize energy levels as you wind down for the night. Just be sure to enjoy your dinner two to three hours before bedtime to avoid discomfort that could disrupt your rest.
2. Add fiber to your day
Fiber doesn’t just support gut health—it’s also linked to deeper, more restorative sleep. Unfortunately, 95 percent of Americans don’t meet the recommended daily intake of 25-38 grams, averaging just 16 grams a day.
Fiber plays a key role in calming the body through its impact on the gut-brain axis. According to a 2023 study, fiber metabolism improves the gut barrier, reduces inflammation, and supports serotonin production. Serotonin is the precursor to melatonin, the hormone that regulates sleep. Foods like fruits, vegetables, beans, and whole grains are excellent fiber sources, so consider adding more of these to your meals.
3. Consider magnesium before bed
Magnesium has earned its reputation as a sleep hero, and for a good reason. This essential nutrient supports over 300 processes in the body, including neurotransmitter regulation and muscle relaxation.
Magnesium helps activate gamma-aminobutyric acid (GABA) receptors, which promote relaxation and prepare the body for rest. For the best results, try magnesium bisglycinate, a highly absorbable form often recommended for sleep. Taking it an hour or two before bed can help you unwind, especially when paired with calming ingredients like jujube seed extract.
4. Skip the late-night sugar
Craving a sweet treat before bed? Be cautious. Sugary or carb-heavy snacks can spike your blood sugar, giving you an energy burst when your body needs to wind down. The crash that follows can trigger cortisol—your stress hormone—which should be at its lowest at night.
Instead of reaching for a cookie or candy bar, opt for low-sugar alternatives like a sleep-supporting smoothie or no-sugar chocolate truffles. These choices can satisfy your sweet tooth without interfering with your rest.
5. Time your water intake wisely
While staying hydrated is essential, drinking too much water right before bed can lead to frequent nighttime bathroom trips. These interruptions can diminish your overall sleep quality.
Urologist Vannita Simma-Chiang, M.D., suggests taking your last sip of water three to four hours before bedtime. This allows your body to process the liquid before sleep, reducing the likelihood of waking up during the night.
Optimizing your sleep isn’t just about perfecting your bedroom setup. What and when you eat plays a crucial role in helping you fall asleep faster and stay asleep longer. By prioritizing protein, adding more fiber, considering magnesium, avoiding late-night sugar, and timing your water intake, you can set yourself up for more restful nights and energized days. Sweet dreams await!
