Nutrition and Oncology
Nutritional epidemiology is continually developing as a consequence of the consummation of late studies, the collaboration with atomic and hereditary research, and the improvement of nourishment creation databases for micronutrients and non-nutritive components in foods. Nutritional epidemiology is the investigation of the nutritional determinants of disease in human populations. It can give understanding into the causation and avoidance of a large portion of today's most vital wellbeing issues, including the chronic diseases of aging. The overall goal of nutritional epidemiology is to contribute to the prevention of disease and the improvement of public health, but this goal cannot be reached through the sole use of epidemiology. Nutritional epidemiology studies can generate information of great relevance to public health. Statistical modelling of the dietary data and the diet-disease relationships can refer to complex programmes that convert quantitative short-term measurements into habitual intakes of individuals and correct for the errors in the estimates of the diet-disease relationships by taking data from validation studies with biomarkers into account. Scientists and policy makers need to appreciate the inherent limits of epidemiology in the detection of weak associations and the complexities involved in measuring dietary intake, avoiding bias, dealing appropriately with confounding factors, analysing data and assessing causality.
