A new study found eating less fiber, more saturated fat, sugar is associated with lighter, less restorative, and more disrupted sleep. Results show that greater fiber intake predicted more time spent in 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.

“Our main finding was that diet quality influenced sleep quality,” said Marie-Pierre St-Onge, PhD, assistant professor in the department of medicine and Institute of Human Nutrition at Columbia University Medical Center in New York, N.Y. “It was most surprising that a single day of greater fat intake and lower fiber could influence sleep parameters.”

The study also found that participants fell asleep fas...

The high amounts of dietary sugar in the typical Western diet may increase the risk of breast cancer and metastasis to the lungs, according to a study at The University of Texas MD Anderson Cancer Center. The findings, demonstrated dietary sugar’s effect on an enzymatic signaling pathway known as 12-LOX (12-lipoxygenase).

“We found that sucrose intake in mice comparable to levels of Western diets led to increased tumor growth and metastasis, when compared to a non-sugar starch diet,” said Assistant Prof. Peiying Yang, Ph.D. “This was due, in part, to increased expression of 12-LOX and a related fatty acid called 12-HETE.”
