Could Eating White Bread Every Day Ruin Your Sleep?

Older women who eat a lot of sweets and white bread may be more likely to have insomnia.

A study of food diaries kept by more than 50,000 women in the mid-60s revealed processed grains and sugar are linked to the sleep-stealing condition. 

Scientists in New York City suggested eating a lot of sugar could make blood sugar levels vary so much that the body starts to release hormones which keep people awake.

It could also be the case that sleep loss could make people develop cravings and eat more, meaning the effect could run the other way.
