Methods The constructions of food, the varieties and amounts of food absorption in 3 consecutive days were investigated. Each 50 families respectively from town, rural area, fishery region and district producing salt were chosen as random stratified sample during off-and peak seasons for seafood. The averaging daily IAC of each crowd was calculated based on the statistical forms of food composition and iodine concentration in food reported previously. The results were analyzed with SPSS software and then compared with Recommended Dietary Allowance recommended by ICCIDD.
