You'll Sleep More Soundly

The science: The more sugar people ate in a day, the more often they roused from sleep that night, per research in the Journal of Clinical Sleep Medicine.

The takeaway: If you want better sleep, watch your added sugars. You'll wake up more rested, and research suggests that getting adequate sleep is associated with better control over your eating habits. You can also try adding more fiber to your diet—high fiber intake was associated with more time in deep, slow-wave sleep, which is highly restorative.
