A study in the January issue of the Journal of Clinical Sleep Medicine suggests that diet can influence nighttime sleep propensity, depth and architecture. Results show that a greater intake of saturated fat and lower intake of fiber were associated with a lighter, less deep sleep profile. Additionally, increased intake of both sugar and non-sugar/non-fiber carbohydrates was associated with more nocturnal arousals during sleep.
