Diet and nutrition: key factors in cancer prevention

The role of diet and nutrition in cancer prevention has garnered significant attention as a key area of public health research. This review evaluates the impact of various dietary patterns and nutritional factors on cancer risk reduction. We systematically analyze evidence from epidemiological studies, clinical trials, and meta-analyses to identify dietary components and nutrients associated with lower cancer incidence. Key topics include the protective effects of high-fiber foods, fruits, vegetables, and whole grains, as well as the potential risks associated with excessive consumption of processed meats and high-fat diets. The review also explores the role of specific nutrients, such as antioxidants, vitamins, and minerals, and their mechanisms in modulating cancer-related pathways. By synthesizing current findings, we aim to provide a comprehensive understanding of how dietary choices can influence cancer risk, offering practical guidelines for individuals and health professionals to integrate into cancer prevention strategies.
