Ever wonder why fiber is the talk of the town recently? Well, your gut microbiota, which is the community of bacteria living in your intestines, may be one reason why.
This review suggests that dietary fiber may help support weight management by feeding beneficial gut bacteria. In turn, those bacteria can produce helpful compounds like short-chain fatty acids, which are substances made when gut bacteria break down fiber. These compounds may help support gut barrier health, reduce inflammation, and influence appetite and metabolism.
Want to try it in real life?
• Add one more high-fiber food to your day, like beans, oats, berries, or vegetables.
• Swap some refined grains for whole grains, such as brown rice or whole wheat bread.
• Build meals that include a mix of fiber sources instead of relying on one “superfood.”
Important note: this was a review article, meaning it summarized existing research rather than testing one new intervention. The authors also noted that fiber’s effects can vary by fiber type, dose, and a person’s existing gut microbiota, and that more human studies are still needed.
