Scientists warn that changing diet could affect our IQ

Scientists warn that changing diet could affect our IQ

We need iodine, a mineral found in some foods, to make thyroid hormones that control the body’s metabolism and support proper brain and bone development during childhood. People who don’t get enough iodine in their diet can’t make enough thyroid hormone. According to the US National Institutes of Health (NIH), this can lead to developmental problems, including arrested fetal and infant development. Severe iodine deficiency in childhood has deleterious effects on the developing brain and nervous system, and “mild” iodine deficiency “might” cause “subtle problems with neurological development,” the NIH suggested.

UNICEF data suggests that 89% of the world’s population used salt with “some iodine” in 2020, a fact that has been key to the reduction of iodine deficiency disorders (IDD). However, scientists at the World Iodine Association’s (WIA) 2nd international conference on iodine in food systems and health warned that a change in consumption habits could lead to a resurgence of TDIs with a possible ” long-term impact on brain development in European populations”.

The conference, which opened today in Rotterdam this week, heard that iodine is a critical ‘but largely overlooked’ essential nutrient.

“Today, thanks to global awareness campaigns, close to 90% of the world’s population uses iodized salt in their diet. However, this achievement is under threat due to many factors, including reduced awareness and commitment politics and changes in food consumption patterns, “suggested Dr. Werner Schultink, Executive Director of the Iodine Global Network.
