Foods to avoid before bed

Sleep tight, but don't let your snacking bite. Cereal, coffee and pizza are among the foods that can aggravate your sleep cycle.

“Particularly the sugary cereals will spike your blood sugar, and that messes with your sleep,” Catherine Kruppa of Advice for Eating said.

Kruppa said sugary foods make your blood sugar rise and then drop and you don't sleep as well, so almost anything sweet will mess up your sleep, including coffee.

“Six hours before is when you want to cut off caffeine,” she said.

The biggest misconception might be alcohol.

“Alcohol is one many people drink to get them to go to sleep, and it does make you tired initially, but it definitely messes with your sleep ... you don’t sleep as well and as deep," Kruppa said.

She said it also might be painful to sleep if you're prone to acid reflux and eating high-fat foods late at night.

“Pizza, for instance, is greasy but it also has tomato sauce,” Kruppa said. “(The culprits are) the acidic tomato sauce and the high fat in the pizza. So in general, high-fat meals -- burgers, really heavy meals, that kind of thing -- will disrupt your digestive tract so (it) just might be uncomfortable and are more likely to cause acid reflex.”

Kruppa said acid reflux is made worse when a patient is lying down.
Spicy foods and citrus are also known to bother some people.
