Summary

A study analyzing gut microbiomes of over 12,000 people across 45 countries found that higher fiber intake may promote beneficial bacteria (Faecalibacterium) that suppress harmful ones like E. coli.

These bacteria produce short-chain fatty acids, which are linked to better gut health.

While the study shows associations—not causation—experts emphasize fiber’s proven benefits for diabetes, weight control, and heart health.

Most Americans consume only 58% of the recommended daily fiber (30g). Whole grains, fruits, vegetables, and legumes are key sources for increasing fiber intake.

One of the major reasons eating more plant-based foods is so nutritionally beneficial compared to a typical American diet is that 95% of Americans don't eat a sufficient amount of fiber.
