Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase II, randomized pilot trial studies the effect of the consumption of foods made with resistant starch compared to foods made with corn starch on biomarkers that may be related to colorectal cancer progression in stage I-III colorectal cancer survivors. Foods made with resistant starch may beneficially influence markers of inflammation, insulin resistance, and the composition of gut bacteria in colorectal cancer survivors.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants are randomized to 1 of 2 groups.

GROUP I (INTERVENTION GROUP): Participants eat a diet consisting of resistant starch foods daily for 8 weeks. Study provided foods are in addition to their own usual daily diet.

GROUP II (CONTROL GROUP): Participants eat a diet consisting of regular corn starch foods daily for 8 weeks. Study provided foods are in addition to their own usual daily diet.
