High-Fiber Thanksgiving Side Dishes

Thanksgiving is a holiday filled with gratitude, family, and—of course—food. But between buttery mashed potatoes, rich casseroles, and sugary desserts, many traditional dishes are low in fiber and high in refined ingredients. This combination often leaves us feeling sluggish, bloated, and ready for a nap long before dessert is served.

The good news? With a few thoughtful swaps, you can enjoy all the flavors of Thanksgiving while adding fiber-rich side dishes that support gut health, stabilize blood sugar, and leave you satisfied without the crash.

In this post, you’ll find a collection of gut-friendly, high-fiber Thanksgiving sides that bring nutrition and flavor to your holiday table.

Why Fiber Matters at Thanksgiving

1. Supports Digestion
   Fiber keeps things moving smoothly and helps prevent constipation during heavy holiday eating.

2. Feeds Your Gut Microbiome
   Prebiotic fibers in foods like beans, apples, and squash fuel beneficial bacteria.

3. Balances Blood Sugar
   Fiber slows the breakdown of carbs, preventing spikes and crashes from Thanksgiving sweets.

4. Promotes Satiety
   High-fiber dishes help you feel full and satisfied, reducing the temptation to overeat.
