Choosing a plant-based diet may lead to more rest, with some followers sleeping up to 48 minutes longer per night than average.

The Connection Between a Plant-Based Diet and Sleep Quality

Dietary choices significantly influence how long you sleep and the quality of that rest. Survey data shows that vegans and vegetarians sleep an average of 36 minutes more per night than the general population, with 90% reporting excellent or good sleep quality. Those who follow a raw food version of a plant-based diet see even greater benefits, averaging 48 additional minutes of sleep and a 97% above-average quality rating.

In contrast, people who do not follow a specific nutritional plan sleep 12 minutes less than average, and only 36% rate their sleep quality as above average.

The Role of Plant-Based Foods and Other Nutrients

Incorporating specific plant-based foods and other nutrient-dense options can support better slumber:

Fruits: Eating kiwi or tart cherries can increase sleep by 24 and 30 minutes per night, respectively.
Proteins and Fats: Consuming fatty fish 4 to 6 times a week is linked to 42 more minutes of sleep.
Probiotics: Yogurt snackers average 18 more minutes of sleep than average. This may be because gut bacteria help create neurotransmitters like GABA.
General Nutrients: Foods rich in potassium, magnesium, fiber, and protein are recommended for better sleep quality.

To avoid disrupting your cycle, experts suggest stopping eating two to three hours before bed. If you are hungry, a small amount of nut butter or half a banana may help.

Foods That May Disrupt Sleep

Certain eating habits can trigger a “vicious cycle” where poor diet leads to poor sleep, which then increases cravings for comfort foods.

Processed Sugars: High-sugar treats and processed foods can cause blood sugar spikes. This may activate the kidneys, leading to bathroom trips and “micro awakenings” that fuel insomnia.
Salty Snacks: Popcorn eaters reported some of the worst results, sleeping 12 minutes less than average.
Heavy Meals: Large portions or heavy foods eaten within two hours of bedtime can worsen nighttime awakenings.

Sleep Disorders and Plant-Based Protein

There is a link between nutrition and chronic sleep conditions. Research indicates that people who prioritize plant-based protein and healthy plant-based foods—such as nuts, whole grains, vegetables, and fruits—have a 17% lower risk of developing sleep apnea compared to those who eat mostly animal-based foods. This risk is higher for those who eat unhealthy plant options, such as salty chips or refined grains.

Conversely, some specific dietary patterns show higher rates of insomnia. About 48% of intermittent fasters and 47% of those on diabetic or gluten-free diets report struggling with insomnia.

When to See a Doctor

Consult a healthcare provider if you experience the following:

Regular difficulty falling or staying asleep (insomnia).
Excessive snoring or gasping for air during sleep.
Significant weight gain that may precipitate sleep apnea.
Persistent daytime fatigue despite attempting dietary changes.
