Abstract
DURING our investigations1 on the biological value of the proteins of typical Indian diets, it was found that the proteins of the Madras diet gave a biological value of 44 at 10 per cent protein level, though rice with a biological value of about 83 formed the major item of the diet. In the course of an informal discussion with Dr. W. R. Aykroyd, director of the Nutrition Laboratories, Coonoor, he suggested that the low biological value might be due to a low content of calcium in the diet. Experiments were conducted with addition of calcium in the form of calcium carbonate to the Madras diet. Results are given below:
