Can eating iodized salt prevent nuclear radiation? Beijing CDC rumors

CCTV News:According to WeChat official account, Beijing Center for Disease Control and Prevention, Japan announced that it would start discharging nuclear polluted water from Fukushima into the sea on the afternoon of August 24th, which caused global concern and heated discussion. Many citizens in Beijing also started to snap up edible salt. Some citizens think that "iodized salt can prevent nuclear radiation", which is incorrect. Many citizens want to know whether iodized salt can prevent the accumulation of radioactive iodine in the thyroid gland, so as to protect the thyroid gland.

The purpose of iodizing salt in China is to prevent and treat iodine deficiency disorders. Because Beijing is an iodine-deficient area in the environment, iodization with salt can supplement iodine nutrition for the whole people safely, conveniently and for a long time, so as to avoid iodine deficiency affecting the health of residents. According to China’s "National Food Safety Standard Iodine Content of Edible Salt", the iodine content in iodized salt is 20-30mg per kilogram. In a nuclear pollution accident, radioactive iodine is mainly accumulated in the thyroid gland. In the early stage of the accident, it is necessary to take 100mg of "stable iodine" once, which is equivalent to taking 3-5kg of edible iodized salt once. The Dietary Guidelines for China Residents (2022) clearly states that "adults should not consume more than 5g of salt every day". If excessive intake occurs, it will cause serious burden to various organs of the human body, induce or aggravate cardiovascular and cerebrovascular diseases and chronic nephropathy, and even cause dehydration and even death in severe cases.

Therefore, it is not advisable to prevent nuclear radiation by eating iodized salt!
