Cancer is a complex disease influenced by genetics, lifestyle, and environmental factors. Diet is a key aspect, with studies showing that healthy eating habits can reduce the risk of cancers like colorectal and breast cancer. However, understanding the interplay of diet, lifestyle, and biological factors in these cancers remains a challenge. To improve public health strategies, especially in diverse populations, a deeper understanding is essential.
The World Cancer Research Fund (WCRF) has outlined seven factors that reduce cancer risk, including diet and lifestyle elements like body weight, physical activity, and consumption of whole grains, fruits, and vegetables. To assess the impact of diet on cancer risk, researchers use the WCRF score, which includes five dietary components. The study will explore how the WCRF scores relates to the incidence of these cancers, considering various factors like age, socioeconomic status, ethnicity, and family history. In addition, the expansion of the WCRF score to include markers of omega-3 fatty acid (n-3 PUFA) intake, will also be tested to understand their role in modifying the risk of breast and colorectal cancer. These diet-cancer studies help validate the WCRF score’s effectiveness in cancer prevention and assess the importance of omega-3 fatty acids in this context for the next steps.
The field of nutrigenomics examines how genetics and diet interact to influence health outcomes. By analyzing genetic risk profiles and novel genetic markers alongside dietary factors, we aim to understand how diet moderates cancer risk in individuals with different genetic predispositions. This could lead to personalized cancer prevention strategies, offering valuable insights for public health officials and clinicians. This research will clarify the role of diet in genetic susceptibility to cancer, aiding in the development of targeted prevention strategies.
