Take it with a grain of iodised salt

摘要

A study conducted by the New Zealand Food Safety Authority (NZFSA) shows that if you choose to add salt to your food, it pays to make it the iodised variety. The study, which evaluated the level of iodine in 20 salt products available for retail sale- six iodised salt products and 14 non-iodised sea, rock, and low-sodium salt products - showed that iodised products contained about 30 times more iodine than non-iodised products. While iodine content in the iodised products on average ranged from 32-64 milligrams per kilogram of salt, in the non-iodised products it ranged from 1-5 milligrams per kilogram of salt.
