Turkey Day is around the corner and many of us are gearing up for a big Thanksgiving feast. As a registered dietitian and associate nutrition editor of EatingWell Magazine, I’m often asked about the healthiest and worst holiday foods. (Green Bean Casserole or Sweet Potato Casserole? Gravy or Cranberry Sauce? Find out the Best & Worst Thanksgiving Foods.)

I’m lucky that I don’t (usually) have trouble falling—or staying—asleep. But there are definitely nights, sometimes even stretches of nights, where I don’t get enough sleep—and I’m not alone: an estimated 50-70 million Americans, according to the Centers for Disease Control, don’t get enough sleep. (Get 3 simple tips to help you beat insomnia here.)

If you’re looking for the easiest possible dessert to whip up for Thanksgiving, it doesn’t get any simpler than pumpkin pie. If you can open a can, you can make pumpkin pie. And unlike other Thanksgiving desserts, it’s relatively healthy (or at least it can be). Pumpkin, like all orange foods, is a rich source of beta carotene, which your body converts to vitamin A. Vitamin A plays an important role in bone growth, reproduction and immune function and, perhaps most notably, vision. One slice of our pumpkin pie provides 137% of the daily value of vitamin A.

I’m a big believer that Thanksgiving is not a day to diet. Once a year, you get to gather ’round the table with family and friends, count your blessings and eat delicious holiday dishes to your heart’s content.

I’m not saying you should go nuts and have three servings of turkey, four different types of potatoes and two slices of pie with double the whipped cream. But I do think that you should definitely go ahead and eat a little of everything you like.
