Summary

This study tests whether eating 3-6 servings of fermented foods daily (like yogurt, kefir, and sauerkraut) can improve how well cancer treatments work in patients with locally advanced rectal cancer or non-small cell lung cancer. The 39 participants are randomly assigned to either the fermented food diet or standard care. Researchers will measure tumor response, gut microbiome changes, and quality of life.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Fermented foods (yogurt, cottage cheese, kefir, kombucha, sauerkraut, kimchi)
What this could lead to: If it works, this diet could help improve how well cancer treatments work and boost quality of life for patients with rectal or lung cancer.
What could go wrong: This is a small, early-stage trial with only 39 participants, so results may not apply to everyone. The diet is an add-on, not a replacement for standard care.
