Research has explored various dietary factors influencing sleep patterns. A study in Nature Health suggests that plant-based diets rich in fiber and nutrients, such as fruits, vegetables, whole grains, legumes, and nuts, are linked to deeper, more restful sleep and increased REM sleep. The consumption of minimally processed plant foods was also associated with lower nighttime heart rates.

Further research published in the British Journal of Nutrition examined the potential benefits of asparagus extracts. A systematic review involving 16 studies suggested that these extracts might improve sleep quality, anxiety levels, and certain cognitive functions. However, experts noted that these findings were based on small, short-term studies using concentrated supplements rather than whole vegetables, and results regarding specific sleep parameters remained mixed.
