Are sweets at bedtime a bad idea?

Jack wrote, “What is the deal with not allowing kids to eat dessert before bed? That’s how I was brought up, and how my kids have been brought up. My fiancée doesn’t allow her kids to have sweets after about 7:30 because she fears it will interfere with their sleep. Any truth to that theory? Or is it an old wives tale like not swimming after eating?”

That’d be one of those handy “little white lies.” Medically speaking, there’s no particular reason not to have sweets before bed, or (gasp!) not to eat prior to swimming.

I suppose if Junior does have a big bowl of ice cream, he’d better be sure to brush his teeth at bedtime. And a full belly at bedtime might just increase the chance of a nightmare. But I don’t think it really matters what the bedtime snack is.

There is a persistent feeling among many parents (and grandparents) that sugary, junky food gets kids hyper. I think that’s because these kinds of foods are often eaten at birthdays and happy occasions, when kids do get worked up. But when it’s been studied, simple carb meals don’t seem to change behavior in children, at least not when the kids and the observers are blinded. One study even looked at a small number of children with attention-deficit disorder, and found that sugar didn’t worsen their behavior. Those authors suggested that the perception of worse behavior may be related to those kids’ difficulty in adjusting back to classroom behavior after a snack.

In any case, I’ve found that it’s just about impossible to dispel the sugar-misbehavior contention, and I suspect it will be just as hard to convince parents that desserts before bed are no worse than desserts with dinner. It’s never bothered me or my kids, but if you’ve found it’s better to not have sweets later, that’s fine with me. It will at least make your dentist happy too.

  1. We have a snack before bed most nights in our home. We all have a big sweet tooth but we eat well for meals, are very active, and are of normal weight. The kids sleep the same with or without a snack. I only have trouble if the phone rings…

    I did want to share the “milk and cookie disease” though: http://www.kumed.com/medical-services/otolaryngology/pediatric-otolaryngology/milk-and-cookie
