Dietary Reference Intakes of sodium for Koreans: focusing on a new DRI component for chronic disease risk reduction.

Sodium is a physiologically essential nutrient, but excessive intake is linked to the increased risk of various chronic diseases, particularly cardiovascular. It is, therefore, necessary to accomplish an evidence-based approach and establish the Korean Dietary Reference Intakes (KDRIs) index, to identify both the nutritional adequacy and health effects of sodium. This review presents the rationale for and the process of revising the KDRIs for sodium and, more importantly, establishing the sodium Chronic Disease Risk Reduction Intake (CDRR) level, which is a new specific set of values for chronic disease risk reduction.

The Associations of Dietary Intake of High Sodium and Low Zinc with Gastric Cancer Mortality: A Prospective Cohort Study in Korea.

Sodium and zinc display opposite effects on immune cells, such as regulatory T cells (Tregs) and T helper 17 cells (Th17), resulting in an altered immune response. Immune cells have a pivotal role in regulating tumor progression, which may affect gastric cancer (GC) mortality. Thus, this cohort study investigated the associations between the combination of sodium and zinc intake and GC mortality and whether these associations differ by histological type by following up deaths of GC cases in Korea.
