3 Things An Oncology Dietitian Says She Would ‘Never Do’—#1 Increases Risk Of 6 Different Cancers!

2. She Never Takes Supplements Without Her Doctor’s Guidance

Another thing Nichole avoids? Random supplements.

“I do not take any supplements unless my doctor recommends it,” she says. Instead, she focuses on getting nutrients from whole foods, not pills. While it might seem like taking high-dose vitamins could offer protection, she cautions that certain supplements in excess can actually increase cancer risk, rather than reduce it.

“Do not seek out supplements to reduce cancer risk,” she says. “Because in fact, high doses of supplements can increase cancer risk.”

3. She Avoids Processed Meats

Nichole also highlighted the connection between processed meats and colon cancer. Foods like bacon, sausages, and deli meats are classified by the World Health Organization as Group 1 carcinogens—meaning there’s strong evidence they increase cancer risk.

“Processed meats do increase risk for colon cancer,” she says, pointing to the importance of being mindful of what ends up on your plate.

The Bottom Line

Nichole's approach is rooted in science and years of firsthand experience with cancer patients. Her rule of thumb? Stick with real, whole foods, avoid unnecessary risks, and always talk to a trusted medical provider before making changes to your health routine.

“Cancer prevention isn’t about fear,” she says. “It’s about informed choices.”
