According to Sleep Foundation growing evidence indicates that sufficient nutrient consumption is important for sleep. One large study found a lack of key nutrients, such as calcium, magnesium, and vitamins A, C, D, E, and K to be associated with sleep problems. While this research does not prove cause-and-effect, it supports the likelihood that diet affects hormonal pathways involved in sleep.
High-carbohydrate meals with high glycaemic indexes can also affect one’s energy level and sleep quality. It has been well established that high-carbohydrate meals often can make you feel drowsy. High-carbohydrate meals can also impair your sleep quality. In fact, high carbohydrate intake has been shown to increase the number of awakenings at night and reduce the amount of deep sleep you get. It is not a surprise that frequent consumption of energy drinks and sugar-sweetened beverages is associated with poor sleep quality.
