ClinConnect Summary

This clinical trial, titled "Sweet Corn and Carotenoids," is investigating how eating yellow and white sweet corn every day affects certain nutrients in our bodies called lutein and zeaxanthin, which are found in carrots and leafy greens. The study will last for four weeks, during which participants will also have their skin carotenoid levels measured using a device called the Veggie Meter, and researchers will keep track of any digestive symptoms and changes in gut bacteria.

To participate, you need to be at least 18 years old and be able to give your consent in English. It's important that your Veggie Meter score is 250 or lower before starting the trial. Unfortunately, if you have a corn allergy, current gastrointestinal issues, are pregnant, or have taken antibiotics recently, you may not be eligible. While the study is not yet recruiting participants, it offers a unique opportunity to learn more about the benefits of sweet corn and how it might impact your health.
