Salt has been used for thousands of years to flavor & preserve food BUT reliance on fast food, biscuits and tinned goods, with their hidden salt content, has created for us a high salt diet and with it an alarming rise in cardiovascular disease.
Reducing our salt intake, by working with food industry and educating the public (World Salt Awareness Week), should counter this disease epidemic. BUT take this too far, and could an old disease re-emerge? I speak of iodine deficiency in the diet, which can cause abortion, stillbirth, goitres, mental retardation & birth defects: iodized salt solved it.
WHO recommend universal salt iodization for developing countries as a simple, safe and cost-effective measure to address iodine deficiency, and many developed countries follow this too.

People afraid of salt so a disease re-emerges or is unaddressed?
If we ever needed a reminder of the importance of iodized salt & public attitudes to health, you only had to read “salt rumors add to health crisis in pakistan” (Washington Post).
