”The U.S. Dietary Guidelines for Adult Management recommend 2300 mg sodium/day (equivalent to 100 mmol sodium/day, or 5.8 g NaCl/day) for the average adult individual; however, for individuals with hypertension, diabetes, African-American, CKD, or age >50 years, this should be limited to 1500 mg sodium/day (equivalent to 65 mmol sodium/day, or 3.8 g NaCl/day). Unfortunately, however, the actual sodium intake of adult individuals in the United States has been found to be 3000-3500 mg sodium/day, which greatly exceeds the range of sodium intake in the U.S. Dietary Guidelines for Adults. Our adult salt intake is even higher. In 2013, KIDGO guidelines recommended (evidence level 1C) that sodium intake in CKD patients be limited to 2000mg sodium/day (equivalent to 90mmol sodium/day), which is slightly higher than the USDA recommendation to limit sodium at 1500mg sodium/day (equivalent to 65mmol sodium/day). Excessive sodium intake leads to volume overload of the body and elevated blood pressure; increased peripheral resistance is not the cause but the result of hypertension; hypertension is the result of disturbance of renal water and salt regulation. With the decline of renal function, CKD patients have reduced sodium excretion on the one hand, and reduced taste sensitivity and increased sodium intake on the other hand, both of which together lead to sodium overload in the CKD organism, directly resulting in endothelial cell dysfunction, increased oxidative stress and inflammatory state of the organism in CKD patients, and at the same time, due to extracellular fluid volume overload in the organism, resulting in elevated blood pressure and clinical proteinuria, a variety of factors together, greatly increase the risk of chronic cardiac events in CKD patients.
