Yes, there are certain foods that could promote better sleep, but the best choice overall is to eat lightly before bed (if at all) and avoid alcohol or stimulants like caffeine. Save larger, protein-rich meals for breakfast and lunch when your body needs the daytime energy.
The connection between food and sleep is complex. You know that what you eat affects your sleep, but did you know that the reverse is also true? Studies now show that people who are sleep deprived tend to eat more fat-rich foods, simple carbohydrates, and fewer vegetables, possibly because sleep loss alters chemical signals connected to metabolism and hunger. In fact, some researchers believe sleep deprivation to be a factor in the rising rates of obesity. Eating and sleeping well are two vital components of health that are tied in surprising ways.
