Galactose Ingestion and Urinary Excretion of Calcium and Magnesium

Abstract
Rats ingesting a 60% galactose diet excrete more calcium and magnesium in the urine than pair-fed animals ingesting glucose. The increased excretion of these ions during galactose feeding is independent of the rate of intestinal absorption. Serum calcium but not magnesium levels are elevated in galactose-fed animals. Animals fed a 60% galactose diet do not develop an acidosis to account for the urinary excretion of calcium and magnesium.
