4 Breakfast Foods That May Help Prevent Colorectal Cancer. Starting your day right can support digestion and lower your risk of colorectal cancer. Dr. Xu recommends these four high-fiber foods on an empty stomach:
1. Oatmeal
Rich in fiber (5.3g/100g), oatmeal promotes bowel movements and prevents constipation. But don’t overeat—it’s a whole grain that takes time to digest.
2. Sweet Potato
Packed with fiber, vitamin A, and minerals, it relieves constipation. Limit portion size if you’re diabetic—it’s high in starch.
3. Lotus Root
Contains fiber and protein that help remove fats and toxins. Chew thoroughly—it’s starchy and best digested slowly.
4. Corn
High in fiber and magnesium, corn boosts gut movement. Be cautious—moldy corn can produce harmful toxins, so always store it well.
Tip: A balanced, fiber-rich breakfast supports a healthy gut—and may help protect against colorectal cancer.
