Answer:
Explanation:
a. This includes consumption as table salt as well as salt from processed foods.
b. This fortification concentration was calculated based on the mean recommended nutrient intake of 150 μg iodine/day + 30% losses from production to household level before consumption, and a 92% iodine bioavailability. Losses depend on the iodization process, the quality of salt and packaging materials and the climatic conditions. Losses could vary widely (4) and this table presents the value considering 30% losses. The monitoring of urinary iodine concentrations will allow adjustment of the selected fortification concentrations.
c. An intake of < 5g="" of="" salt="" per="" day="" corresponds="" to="" who="" recommendations="" on="" sodium="" intake="">
RNI: recommended nutrient intake, is the daily intake, set at the estimated average requirement plus 2 standard deviations, which meets the nutrient requirements of almost all apparently healthy individuals in an age- and sex-specific population group.
Although iodate is more stable, either potassium iodate (KIO3) or iodide (KI) can be used. Iodide may be used for dry, low crystal size and washed or refined salts. While iodate can be used alone and in any type of salt quality, iodide is used in very good quality salt and cannot be added alone. Therefore, some salt producers add sodium carbonate or sodium bicarbonate when they iodize salt, to increase alkalinity, and sodium thiosulfate or dextrose to stabilize potassium iodide. Without a stabilizer, potassium iodide may be oxidized to iodine and lost by volatilization from the product (6).
An estimated additional variability of ±10% during iodization procedures could be considered at the production site for use in quality control and assurance procedures. This variability depends on the iodization methods used and quality assurance system in place.
