Effects of Chronic Excess Salt Feeding: Demonstration of Normal Thyroid Function in Salt-Fed Dogs with Hypercholesterolemia 1

Summary

The hypercholesterolemia associated with chronic excess salt feeding is not due to hypothyroidism. As shown by thyroidal ¹³¹I uptake, by plasma protein-bound iodine concentrations, and by histological studies of thyroid biopsy specimens, there were no significant differences in thyroid function between dogs with and dogs without hypercholesterolemia chronically consuming a high-salt diet.
