Sleep and Nutrition
You are what you eat? Or maybe, You are what you sleep???
Are you struggling getting a restful night of sleep? Did you know your diet can affect your sleep? Diets low in fiber and high in saturated fats are linked to poor quality sleep. In addition, poor sleep is linked to increased risk of chronic diseases and weight gain.

Characteristics of poor sleep quality diets
- High consumption of poor-quality carbohydrates (refined/highly processed foods).
- Drinking sugar-sweetened beverages or energy drinks over 1x per month.
- Consuming spicy foods or high protein foods within 3-hours of going to bed.
- What about alcohol? While alcohol is a sedative and can help you fall asleep faster. Alcohol does wear off and is linked to sleep disruption and worsening of sleep apnea(1)
Melatonin
Melatonin is a unique hormone in that it can aid in restful sleep. While melatonin supplements are available over the counter (OTC), several foods are naturally rich in melatonin aiding in sleep (1). Further melatonin reduces risk of neurodegenerative diseases (Parkinson’s and Alzheimer’s disease) and supports eye health (1).
Melatonin rich foods
- Tart cherries- Is an excellent natural sleep aid, plus it helps your muscles repair and recover faster. Look for tart-cherries in the frozen fruit aisle which can easily be added to smoothies. Or head to the juice aisle and pick up zero-sugar-added tart cherry juice.
- Milk and Eggs- both rich sources of melatonin and lean protein.
- Oily fish- what doesn’t oily fish help! Besides being known for beneficial for heart health, brain health, reduce inflammation and aid in sleep! Low-sodium/sodium-free canned or fresh sardines and salmon are excellent melatonin sources.
Serotonin
Serotonin also known as the happy hormone sends cellular messages throughout your body and brain nerve cells (2). Serotonin is a precursor to melatonin meaning, serotonin is used to create melatonin in the body. Which in return can help support restful sleep (2).
Serotonin rich foods
- Kiwi, rich in serotonin along with vitamin C and folate.
- Tart-cherries, not only contain melatonin but also contain tryptophan, a precursor of serotonin. Making tart cherries a powerful sleep aid.
- Oily fish, excellent melatonin sources and support serotonin regulation in the body.
- Nuts, while nuts contain melatonin as well, they are known for aiding in serotonin development.
