Key takeaways:
- A high-fiber diet increased response to immunotherapy for patients with melanoma compared with a normal healthy diet.
- A high-fiber diet could improve response for other tumor types, too.

Individuals who ate up to 50 g of fiber every day had an objective response rate nearly 50% higher than those who consumed a health-control diet of 20 g in a randomized phase 2 trial.
