Diets containing 0.40 or 0.75 per cent. H3PO4 or 1.20 per cent. citric acid had no harmful effect on rats, as shown by growth, reproduction, blood analysis, gross and microscopic appearance of the organs and teeth, mineral and N metabolism and tissue composition in 2 successive generations. Rats receiving H3PO4retained more P and excreted more P in the urine. The acid was neutralized by the excretion of ammonia by the kidneys, a phosphate shift resulting in an increased titratable acidity and a decreased pH of the urine and by the excretion of more acid calcium phosphate in the faeces. All extra citric acid was metabolised
