Nutritional epidemiology is a relatively new field of medical research that studies the relationship between nutrition and health. It is a young discipline in epidemiology that is continuing to grow in relevance to current health concerns. Diet and physical activity are difficult to measure accurately, which may partially explain why nutrition has received less attention in epidemiology than other risk factors for disease. Nutritional epidemiology uses knowledge from nutritional science to aid in the understanding of human nutrition and the explanation of basic underlying mechanisms. Nutrition The development of dietary recommendations, including those tailored specifically for the prevention of certain diseases, conditions, and cancers, is influenced by these studies' findings, which have an impact on public health. Western researchers say that nutritional epidemiology should be a core part of training for all health and social service professionals because of its growing importance and past successes in improving public health. However, they also say that nutritional epidemiological studies don't always come up with reliable results because they rely on the role that diet plays in health and disease, which is known as an exposure that is prone to a lot of measurement error.
