Fish oil and fiber together reduce colon tumor formation in animals. In humans, there are only studies looking at each separately. We want to understand how the combination works in healthy humans. We will look at changes in health markers and in the gut microbiome.
Participants will take study supplements during two periods. For one month it will be fish oil and corn fiber and for the other, corn oil and a non-fiber corn product (placebo). We will compare the effects within each person.
The purpose of the study is to answer scientific questions. Participants must be able to visit Fred Hutchinson Cancer Center's campus at South Lake Union throughout the 4-month study. Participants will receive $250 for completing the study.
