Not only are eggs loaded in high-quality protein and important nutrients, but these breakfast favorites are a natural source of tryptophan, an amino acid that plays a role in creating serotonin, a chemical that helps regulate sleep cycles.
Although the results are based on adult subjects, data published in British Journal of Nutrition suggests improvements in sleep after 19 days of tryptophan-rich egg-white protein hydrolysate was consumed versus those who did not eat the egg whites.
When it comes to children, a 2022 study in the Journal of Family Medicine and Primary Care shows that dietary protein intake in children aged 2-5 years are associated with better quality of sleep and appetite. Since one medium egg contains a whopping six grams of protein, eating these nutritional powerhouses before bed may offer some benefit.
