Breaking the Cancer Myth: How lifestyle beats genetics …
Can Lifestyle Choices Beat Genetics in the Fight Against Cancer? Expert Shares the Facts
Ashley McIntyre, MS, CNS, LDN, Clinical Nutritionist, Holistic Health Coach, and founder of The Elevated Plate, joined Gayle Guyardo, host of the globally syndicated health and wellness show Bloom, to debunk a common cancer myth: genetics alone determine cancer risk. McIntyre emphasized that while genetics play a role, lifestyle factors have a far greater impact on cancer prevention and overall health.
Genetics vs. Lifestyle McIntyre clarified that only 5-10% of cancers are linked to inherited genetic defects. This means that the vast majority—90-95% of cancers—are caused by lifestyle factors.
How Lifestyle Influences Cancer Risk A balanced, nutrient-rich diet is one of the most powerful tools for reducing cancer risk. McIntyre highlighted:
Protective Foods: Cruciferous vegetables (like broccoli and kale) Berries Foods rich in antioxidants These foods help combat inflammation and protect cells from damage that can lead to cancer. Risky Foods: Diets high in red and processed meats Sugary drinks Alcohol These can promote inflammation and potentially increase cancer risk. The Role of Epigenetics McIntyre also discussed epigenetics—how lifestyle choices can influence gene expression. Even for those who inherit cancer-related genes, external factors like stress, diet, and exercise can either activate or suppress these genes. This means that individuals can take proactive steps to reduce their risk, even if they have a genetic predisposition.
Prevention Prescription To lower cancer risk, McIntyre recommended the following:
Avoid processed foods, including alcohol and cigarettes. Focus on whole foods with a variety of colorful fruits and vegetables. Limit foods with added sugars. Manage stress effectively. Stay active with regular physical movement. For those with a strong family history of cancer, undergoing treatment, recovering, or in remission, McIntyre advised working with a specialized nutritionist to create a personalized plan that supports long-term health.
Final Takeaway While genetics can influence cancer risk, McIntyre’s insights remind us that lifestyle choices play a significant role in prevention. By making mindful changes to diet, exercise, and stress management, individuals can take charge of their health and reduce their risk of cancer, proving that lifestyle can indeed trump genetics.
