It is a welcome move considering the fact that India leads the list of countries with iron-deficiency anaemia. It is common in rural population due to poverty and in urban population due to inadequate diet. That is caste driven taboos and food habits may deprive even the wealthy of iron rich food. Example is the non-veg category of iron rich meat,fish, egg yolk etc.
Whether rich or poor, urban or rural, all populations have to use salt in preparing dishes. So iron fortified salt will certainly do a lot for keeping anaemia at bay.
When iodized salt was introduced, some human rights groups had come out in the open, vehemently criticising it as a means of robbing the poor ( as iodized salt was costlier by about Rs.2- when it was introduced). But these great humanists overlooked the fact iodine deficiency leading to goitre was much more expensive to treat. Iron fortified table salt is another opportunity for these people to make a hue and cry

Good for aneamic persons
