Iodine Biofortification of Vegetables Could Improve Iodine Supplementation Status

Facts of iodine supplementation.

Iodine supplementation in pregnancy.

People of all ages can be affected by iodine deficiency, however, pregnant women and children are especially at a high risk. Because of changes that occur in maternal thyroid hormone economy during pregnancy and the potential unfavorable effects of iodine deficiency on the offspring, an adequate dietary iodine intake throughout the pregnancy is highly important. Therefore, the World Health Orga...

Soil versus foliar iodine fertilization as a biofortification strategy for field-grown vegetables

Iodine (I) biofortification of vegetables by means of soil and foliar applications was investigated in field experiments on a sandy loam soil. Supply of iodine to the soil in trial plots fertilized with potassium iodide (KI) and potassium iodate directly before planting (0, 1.0, 2.5, 7.5, and 15 kg I ha(-1)) increased the iodine concentration in the edible plant parts. The highest iodine accumu...

Low-level seaweed supplementation improves iodine status in iodine-insufficient women.

Iodine insufficiency is now a prominent issue in the UK and other European countries due to low intakes of dairy products and seafood (especially where iodine fortification is not in place). In the present study, we tested a commercially available encapsulated edible seaweed (Napiers Hebridean Seagreens® Ascophyllum nodosum species) for its acceptability to consumers and iodine bioavailability ...

Iodine supplementation improves cognition in mildly iodine-deficient children.

BACKGROUND The effects of severe iodine deficiency during critical periods of brain development are well documented. There is little known about the consequences of milder forms of iodine deficiency on neurodevelopment. OBJECTIVE The objective was to determine whether supplementing mildly iodine-deficient children with iodine improves cognition. DESIGN A randomized, placebo-controlled, doub...
