What Is the Best Diet to Prevent Colon Cancer, New York RDN

Colon Health

What Is the Best Diet to Prevent Colon Cancer?

The numbers are alarming. Colorectal cancer rates are at an all-time high, and The Cancer Research Institute reports that “1 in 5 diagnoses occurs in someone under the age of 55.”


This cancer was once considered a risk primarily for older adults, individuals with a family history of colorectal cancer, or certain racial and ethnic groups. It has now become a leading cause of cancer-related death in younger adults.

The good news is that colorectal cancer is often preventable.

What Are the Symptoms of Colorectal Cancer?

Symptoms can appear in many different ways, though they are not always obvious. If you are experiencing any of the following symptoms, contact your primary care physician right away:

  • Chronic diarrhea or constipation
  • Unexplained weight loss
  • Blood in the stool
  • Cramping or stomach pain
  • Fatigue

Risk Factors for Developing Colorectal Cancer That Are Under Your Control

It is estimated that approximately 50% of colorectal cancer cases may be prevented by modifying lifestyle and dietary factors.

There is strong evidence that the following strategies can help reduce the risk of colorectal cancer:

  • Attain and maintain your optimal body weight
  • Select minimally processed foods

  • Increase fiber intake

  • Include regular physical activity
  • Manage chronic inflammatory conditions
  • Limit alcohol
  • Limit red meat
  • Limit ultra-processed foods

How Can a Dietitian Help You Prevent Colorectal Cancer?

As a Registered Dietitian Nutritionist, Nancy works with patients to improve wellness through individualized nutrition interventions and personalized diet plans. A healthy, balanced diet combined with some lifestyle modifications can help reduce the risk of colorectal cancer.

  • Personalized assessment and goal setting: Nancy evaluates your medical history, diet history, eating patterns, and lifestyle to identify risk factors
  • Tailored nutrition plans: She moves beyond a one-size-fits-all approach, helping you focus on what to add or minimize in your diet to support digestive and colon health
  • Behavioral change and counseling: She works with you to identify triggers, manage emotional eating, and modify unhealthy eating behaviors
  • Nutrition education: You’ll feel empowered to make informed choices for your wellness while understanding the foundations of healthy eating
  • Ongoing support and accountability: Follow-up appointments help assess progress, identify challenges, and adjust plans to support long-term success

Work with Nancy to implement a sustainable, healthy nutrition plan that considers your unique needs, favorite foods, and family traditions. Together, you will focus on practical dietary and lifestyle strategies that support digestive health and overall wellness. Colorectal cancer can be prevented with moderation, balance, and sustainable change.

I was hesitant at first to start seeing a nutritionist. I was very comfortable with my poor eating habits despite being upset about my weight; however I knew I needed to make a change.

Nancy was very understanding from the start. Before meeting with Nancy, I had been in a constant cycle of over-restricting myself to lose weight rapidly, followed by binge eating and gaining it all back plus some more.

Over the past year and a half, Nancy has helped me discover normal eating. She helped me understand my hunger and my fullness in addition to helping me choose better food options.

Nancy is very dedicated to working with you and helping you achieve your goals. She doesn’t just help you reach your goals — she helps you change your perspective of food and eating for the better. What you learn with Nancy is not temporary — you will carry it with you and practice it throughout your life.

I have lost almost 70 pounds since first meeting with Nancy and continuing on my journey. I highly recommend working with her.

Nancy, thank you for all of your help!

Although I was unlucky when I developed some health issues, I was very lucky to find Nancy Mazarin, a skilled, intelligent, caring nutritionist. I saw lots of doctors but she was the one who came up with the diagnosis that finally led to my improved health. She was always available when I had questions and was even willing to meet with me one weekend when I was struggling.
