A new study found that eating less fiber, more saturated fat and more sugar is associated with lighter, less restorative, and more disrupted sleep. – diet quality influences your sleep quality.

Published in the Journal of Clinical Sleep Medicine, results showed that greater fiber intake predicted more time spent in the stage of deep, slow wave sleep. In contrast, a higher percentage of energy from saturated fat predicted less slow wave sleep. Greater sugar intake also was associated with more arousals from sleep.

The study also found that participants fell asleep faster after eating fixed meals provided by a nutritionist, which were lower in saturated fat and higher in protein than self-selected meals. It took participants an average of 29 minutes to fall asleep after consuming foods and beverages of their choice, but only 17 minutes to fall asleep after eating controlled meals.

The study can be interpreted that diet and sleep are interwoven in the fabric of a healthy lifestyle and that for optimal health it is important to make lifestyle choices that promote healthy sleep, such as eating a nutritious diet and exercising regularly.
