I like to think I'm pretty bright. Maybe that's because my mum got enough iodine in her diet when she was pregnant with me.
A new study shows mild iodine deficiency in pregnant women could lower their child's IQ by three points. It may not seem much of a problem, but two-thirds of women are iodine deficient.
Does that justify putting iodine supplements in our food? Shouldn't we do all we can to give the next generation the best start in life?
