When most people think of wheat, they picture sandwich bread, pasta or baked goods. But beyond being a tasty staple in many meals, wheat offers a lesser-known benefit that your gut will thank you for — it contains prebiotics.
You’ve likely heard of probiotics, the beneficial bacteria that support digestion and immune health. But for those good bacteria to thrive, they need to eat — and that’s where prebiotics come in. Prebiotics are non-digestible fibers that feed the healthy bacteria in your gut, helping them grow and do their job more effectively.
Whole wheat foods, in particular, are a great source of these prebiotic fibers. That means your morning whole wheat toast or hearty bowl of wheat-based cereal isn’t just fueling your day — it’s supporting your gut health from the inside out.
Adding more wheat-based foods to your diet is a simple and delicious way to nourish your body and your microbiome. Pair that with plenty of water and a balanced diet, and you’ve got a gut-friendly routine worth sticking to.
So next time you reach for wheat, know that you’re doing more than just satisfying your hunger — you’re feeding the good guys in your gut.
