Abstract
1) Oxalic acid, calcium, and protein content, caloric value, and calcium/oxalic acid ratio have been determined in different types of diets in Rajasthan. Oxalic acid consumption by the urban upper socioeconomic group is higher as compared with the lower socioeconomic group. The highest content of oxalic acid has been recorded in the seasonal rural diet. 2) The calcium/oxalic acid ratio lies on the safe side of the toxic level in the hospital and urban diets. It is clearly unfavorable in the seasonal rural diet. 3) A food calendar is suggested as a guide to the proper selection of food items for normal individuals and those suffering from urolithiasis or calcium deprivation states.
