Do you ever have trouble falling asleep? Maybe you find yourself tossing and turning throughout the night? While many of us can relate, lack of sleep is a topic that often doesn’t get much spotlight in the realm of health.

There is mounting evidence that demonstrates how important restful sleep is to both our mental and physical health.1 In fact, studies show that lack of quality sleep can negatively impact blood sugar regulation, hormone levels, increase our risk for cardiovascular disease, diabetes, and weight gain, decrease immune function and decrease attention and memory.

Poor sleep quality can lead to obesity and other health issues.

The National Sleep Foundation recommends that adults aim for 7-9 hours of sleep per night1. Similar to how sleep can impact food choices we make throughout the day, the food we eat can also impact our sleep quality.1-2 What are some of the key nutrients to focus on when trying to improve sleep?

B vitamins and magnesium: A diet that lacks B vitamins and magnesium may influence sleep quality. Both B vitamins and magnesium play an important role in the synthesis of melatonin – a hormone that is essential for restful sleep.2 Foods that are high in B vitamins include legumes, whole grains, dairy, sweet potato, eggs, nuts, and leafy green vegetables.3 As for magnesium, consuming just a quarter cup of pumpkin seeds meets almost one hundred percent of your daily requirements.4

Turkey is well known for its tryptophan content.

Tryptophan: Tryptophan is a building-block of serotonin. Serotonin is needed for the production of melatonin, which helps to promote sleepiness.Tryptophan is an essential amino acid, meaning you need to consume it from your diet in order to meet your daily requirements.5 Protein foods tend to be great sources of tryptophan, including turkey, eggs, dairy, chicken, soybeans, fish and nuts.6 Consuming these foods with a small amount of carbohydrate such as sweet potato, oats, or whole grain crackers can help make tryptophan more available to the brain. 2,6

Vitamin D: Similar to the above nutrients, vitamin D plays an important role in the regulation of serotonin and therefore sleep regulation.7 Incorporate foods such as fatty fish several times per week to increase dietary vitamin D intake. Should you wish to add a vitamin D supplement, always discuss with your health care provider first.

Red wine may help you get to sleep at bedtime, but not to stay asleep.

While there are foods that can help promote restful sleep, what about foods that may do the opposite? A glass or two of wine before bed might help you fall asleep, but it could actually prevent you from entering the deeper stages of sleep leaving you feeling tired despite being in bed for an adequate amount of time.There also seems to be a correlation between a higher intake of total dietary fat and shorter sleep duration,suggesting that a high fat diet may have a negative impact on sleep.

Overall, when looking at the evidence, a diet that is rich in fruits and vegetables, whole grains, unrefined carbohydrates and contains a variety of protein sources can help improve the quality of your sleep.6,7
