True iodine deficiency is quite rare in the west as many table salts are fortified with iodine. It is extremely uncommon to see people with Goiter in the US. The same goes for thiamine/B1 deficiency which used to cause cardiovascular and neurological disease in alcoholics, but is now very rare becuse many pastas/breads/cereals are fortified with B1.
