Dairy & Diet: Foods That May Protect Against Colorectal Cancer

While there is currently no miracle cure for cancer, our diet can genuinely play a preventative role. Carefully composing meals, prioritizing foods with protective properties, helps strengthen our natural defenses.

And among these health allies, some foods often criticized deserve to be reconsidered. Dairy products, rich in calcium, now have their benefits for colorectal cancer prevention supported by science.

Dairy Products as True Anti-Cancer Allies, According to This Physician

As a reminder, colorectal cancer affects the colon or rectum, two parts of the large intestine, and is one of the most frequent cancers in Western countries. Fortunately, recent studies confirm the benefit of regular calcium intake to limit this risk. Contrary to popular belief, dairy products, often criticized, can have a protective role.

Dr. Jimmy Mohamed recalls the importance of these foods: Dairy products get a lot of criticism, but in reality, children should consume three dairy products per day, and adults two, due to the fact that calcium protects against colorectal cancer. A large-scale study conducted in 2025 confirms his statements: each additional 300 mg of calcium consumed daily was associated with a 17% reduction in the risk of developing colorectal cancer.

The protective mechanism appears to involve calcium binding to bile acids in the colon, reducing their potential to damage the intestinal lining, according to research. This process may help prevent the development of colorectal cancer.

Colorectal cancer is the third most common cancer for both men and women, making preventative measures like dietary adjustments particularly important. Smart food choices, alongside regular exercise and maintaining a healthy weight, may significantly lower the risk of developing this disease – potentially by more than a third, according to some studies.

Beyond Dairy: Fruits, Vegetables, and Fiber are Key

But dairy products aren’t the only foods to incorporate into a preventative approach. Dr. Jimmy Mohamed highlights three key families: Fruits and vegetables, it’s simple. There are antioxidants. The more colorful a vegetable, the more vitamins and antioxidants it has. Among them, flavonoids – quercetin and fisetin in particular – found in berries, stand out for their anti-cancer power.

Dr. Mohamed also cites fiber: lentils, legumes, chickpeas, whole grain products…. These elements strengthen the gut microbiome and decrease the risk of inflammation, two major levers in preventing digestive cancers!

The benefits of fiber extend beyond cancer prevention. By keeping stools moving, fiber can help remove cancer-causing compounds from the colon. Aiming for 90 grams of whole grains daily – such as oatmeal, whole wheat bread, and brown rice – is a good starting point.

While the research on fruits and vegetables linking them directly to preventing colon cancer has been mixed, cancer organizations still recommend them as part of a healthy diet. Prioritizing a variety of colorful produce ensures a broad intake of vitamins, minerals, and antioxidants.

It’s important to note that while calcium-rich dairy products and a diet rich in fiber, fruits, and vegetables can contribute to reducing the risk of colorectal cancer, they are not a guarantee against the disease.
