All foods were divided in to 12 types and the iodine contents in various diets were determined u sing epithermal neutron activation analysis (NAA). The intakes for Chi na were evaluated. The results indicate that the intakes of iodine in northern areas are slightly higher and in south areas lower than the l owest recommended intake, and the average intake in China is 166 mu g/ person per day, which is within the recommended range. In addition, on e province were chosen from each area groups. The dietary intakes of i odine were investigated in different ages and sex using total mixed di et method. Our results indicate that the average iodine intake of four provinces was lower than the recommended value, which suggests that i f is necessary to supplement iodine in foods in China.
