In fact, the combination of omega-3 fatty acids and vitamin D found in fatty fish has the potential to enhance sleep quality, as both have been shown to increase the production of serotonin.
Serotonin is a chemical responsible for stimulating the parts of the brain that control sleep and waking.
In one study, men who ate 10.5 ounces (300 grams) of Atlantic salmon three times a week for six months fell asleep about 10 minutes faster than men who ate chicken, beef, or pork.
This effect was thought to be the result of vitamin D.
Those in the fish group had higher levels of vitamin D, which was linked to a significant improvement in sleep quality.
Eating a few ounces of fatty fish before bed may help you fall asleep faster and sleep more deeply.
If you still want to eat a high-carb meal for dinner, you should eat it at least four hours before bed so you have enough time to digest it, research suggests.
