MINIMUM DAILY NEED:
ESSENTIAL FOR: The development of thyroid hormones that regulate your metabolism. WHAT THE EXPERTS SAY: “Iodine deficiency has re-emerged in Australia over the past decade, partly because dairy products no longer contain it after changes in sanitation processes,” Weaver says. “We’re also consuming less iodised salt today than decades ago.” Though commercial bread is fortified with iodine, fewer people are eating it, Lienemann adds. “Organic loaves and make-athome bread mixes don’t have to be fortified, which could pose another concern as more and more people turn to organic foods and home cooking,” she says. SIGNS YOU’RE DEFICIENT: Fatigue, feeling cold, dry skin, weight gain, hair loss, brittle nails. BOOST IT: Include bread in one of your meals each day. Check that it’s made with iodised salt. OR TAKE: A daily supplement of 150mcg, but Weaver says it’s vital that anyone with a thyroid condition consults a health expert before taking additional iodine.
