Myth No.1. Low iodine content in salt is not able to eliminate iodine deficiency

In order not to rest upon suppositions, one needs to present a calculation. A daily norm of iodine consumption for an adult is equal to 150 mcg. Iodine content in the iodized salt by “Russalt” LTD. is 40,0±15 in a gram of salt. From the maximum allowed salt consumption of 10 grams a person can get up to 400 mcg of iodine a day. From the recommended salt consumption of 5-6 grams – up to 200 mcg a day. Thus, one can note that salt in sensible doses is an effective method of iodine deficiency elimination. Iodine content in salt is well balanced, which makes the consumption of iodine as well as of the salt itself moderate. Consuming iodized salt instead of the edible salt, every person in Russia can protect their health and the health of their nearest.

Myth No.2. Iodized salt smells bad, spoils the color and taste of the products, and the most part of the iodine evaporates in the course of storage process

Modern salt iodization technologies allow saying for sure that salt has no specific smell, does not spoil products and has no special taste. Potassium iodide had been used as a salt supplement earlier which really evaporated actively and had a specific smell, at present potassium iodate is used. The difference is exactly in that as the potassium iodate is a more solid connection, which does not let the iodine evaporate from the package during the storage process. As a proof we shall describe an experiment conducted by the specialists of the production chemical laboratory of “Russalt” LTD.

For the experiment a package of iodized salt by “Russalt” LTD. with iodine concentration of 40 mcg in a gram was taken and was left under the light. 2 years later the iodine concentration decreased up to 37 mcg in a gram of salt. A package with a storage period of 9 months was also taken for the experiment. Iodine concentration in this package was the same – 40 mcg in a gram of salt. Thus, even when kept for a long time the salt does not lose its healthy properties. We will underline once again that the salt of “Russalt” LTD. was used for the experiment, so nothing can be said about the quality of other salt.

Myth No.3. In order to keep all the healthy properties of the iodine in salt it is better not to add it to hot dishes

Actually, many people suppose that it is better to use iodized salt as a flavoring additive to cold dishes, as if iodine evaporates from salt in hot condition.

Considering it to be our duty to find out how the temperature influences the solution which contains iodized salt, we have conducted an experiment.

Before the experiment we determine the iodine concentration in salt which corresponds to GOST R 51575-2000 (the Russian national standard) and equals to 42,32 mcg/g. Then we dissolve 10 grams of salt in 200 ml of water and boil it during 20 minutes. Within this period of time up to 100 ml of the fluid evaporates. After the solution gets cold we check the iodine content in the solution – 39,14 mcg/g. To maintain the experimental integrity we repeat the experiment. The results are the same. Thus, we prove that the boiling and heat treatment process does not cause sufficient changes in the solid connection of potassium iodate. It means that iodized salt can be used as well as the usual salt, however iodized salt is healthier.

Myth No.4. Iodine combinations used for salt iodization are toxic, they can cause allergic reactions and even stomach ulcer

Iodized salt contains iodate in very small amounts which are not toxic and cannot lead to allergies or ulcer diseases. Iodine content norms are regulated by the GOST R 51574-2000 requirements.

The statement that potassium iodate is much more toxic than the iodide which had been used before also does not have any ground. Potassium iodate has been declared to be a safe food additive by the Food and Drug Administration of the USA. The European law allows iodate usage as well as potassium iodide usage.

Local use of iodinated medicines causes allergic reactions – when used for wound disinfection or making an iodine grid, but in no way the consumption of the edible iodine norm.

Myth No.5. Iodized salt is a medicine which should be prescribed by a doctor

Iodized salt does not contain pharmacological iodine doses and is a usual food product. The salt rich in iodine does not cure iodine deficiency disorders and does not demand a medical prescription for its usage. Iodized salt is a food product for regular consumption.

So, with the assistance of the production chemical laboratory of “Russalt” LTD. we managed to refute the public points of view (myths) and to convince that the best means of iodine deficiency prevention is the iodized salt produced by us!
