The range and medium of iodine content in each type of product were given. <b>Results:</b> After merging samples with close value in the same style of the same brand, and screening out samples with no added salt or low sodium content (≤120 mg/100g), total 725 data were sub-grouped and analyzed. In comparison with the 95<sup>th</sup> percentile of the iodine distribution in relative nature source, assessed by our previous study, nearly 77% of products made from grains, potatoes, beans, nuts, livestock and poultry meat were presumed to be processed with iodized salt. In somewhat, related with sodium value marked on food labeling, the median iodine ranged from 1.1 mg/100g to 149 mg/100g. The variation of iodine in egg, milk and fish made products, and seaweed or with seaweed products was greatly affected by the background of ingredients, the median content most floated between 12.8 mg/100g and 86.8 mg/100g, even up to 1800 mg/100g in seasoned seaweed. Based on the frequency of iodine digital and the ratio of iodine to sodium, it was speculated that nearly 90% of soy sauce and 73.5% of other seasonings like vinegar, sauce, paste, etc., were not added iodized salt, with overall median iodine 4.0 mg/100g an</span><span>d 12 mg/100g respectively. <b>Conclusion:</b> Using iodized salt in processed foo</span><span>ds is an approach of USI police.

Methods:One hundred and three male weanling rats were fed with feedstuff containing 0,0.5.1.2.5,and 5- fold higher dosage of iodine in standard iodine-additive salt,i.e.200,300,400,700,and 1200μg/kg,respectively, for 130-136 days.The number of rats taking different dosages of iodine was 20,21,21,21,20 respectively.The rats fed 200μg/kg of iodine were taken as the control group.For all groups,their structural changes of reproductive organs and sperm quality were evaluated. Results:The three experiment groups fed with 1,2.5,and 5-fold higher dosage iodine showed apparent reduction in testicular weight(P<0.05-0.01) by 10.76%,14.58%and 25.35%,respectively,compared with the control. But significant reduction in testis/body weight ratio was only observed in the 5-fold higher dosage group.The sperm concentration and total sperm count declined in four experiment groups fed with 0.5-5 fold higher dosage of iodine.The sperm concentration was reduced by 6.59%,22.53%,17.35%and 18.06%respectively.The percentage of sperm with normal and abnormal form significantly changed(P<0.05).The addition of different doses of iodine showed no apparent adverse effects on other reproductive organs or sperm viability. Conclution:These results indicated that excessive iodine intake might cause potential hazards on reproductive organs of male rats with respect to spermatogenesis.展开更多
