Summary

This study tested whether taking a daily mix of dietary fiber and probiotics for 12 weeks could improve gut bacteria, immune function, and nutrition in 80 malnourished patients with advanced colorectal cancer. Participants received either the supplement or standard nutritional advice. The goal was to see if this simple addition could help their bodies fight cancer better.

What this could mean

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

Active substance
Combined dietary fiber powder (inulin, pectin, β-glucan) and multi-strain probiotic capsule (Lactobacillus acidophilus, Bifidobacterium lactis, Streptococcus thermophilus)
What this could lead to
If it works, this could point toward a simple dietary supplement to boost immune function and nutritional status in advanced colorectal cancer patients.
What could go wrong
This is a small, single-center trial with only 80 participants, so results may not apply to all patients. The supplements may cause digestive discomfort or allergic reactions.
