Risk-Benefit Assessment of an Increase in the Iodine Fortification Level of Foods in Denmark-A Pilot Study.

Foods 2022 Apr 28;11(9). Epub 2022 Apr 28.

National Food Institute, Technical University of Denmark, 2800 Kongens Lyngby, Denmark.

Iodine deficiency is one of the most common nutritional disorders worldwide. In Denmark, the mandatory iodine fortification of salt of 13 ppm was introduced in 2000 to eradicate mild to moderate iodine deficiency and the fortification level was increased to 20 ppm in 2019. However, the optimal iodine intake is a narrow interval, and the risk of disease increases with intakes both below and above this interval. Read More

Iodine status during child development and hearing ability - a systematic review.

Br J Nutr 2022 May 10:1-46. Epub 2022 May 10.

Department of Nutritional Sciences, Faculty of Health and Medical Sciences, University of Surrey, Guildford GU2 7XH, United Kingdom.

Iodine, through the thyroid hormones, is required for the development of the auditory cortex and cochlea (the sensory organ for hearing). Deafness is a well-documented feature of endemic cretinism resulting from severe iodine deficiency. However, the range of effects of suboptimal iodine intake during auditory development on the hearing ability of children is less clear. Read More

Doctor I Have an Iodine Allergy.

Ophthalmol Ther 2022 Jun 24;11(3):931-938. Epub 2022 Apr 24.

Department of Ophthalmology, Mayo School of Medicine, 4500 San Pablo Rd., Jacksonville, FL, 32224, USA.

Ophthalmologists frequently face patients who refuse asepsis protocols involving povidone-iodine (PI) due to claims of an allergy to iodine. Such patients usually base this claim on previous reactions to shellfish consumption or to imaging procedures that used iodine-based contrast agents. Allergy to iodine, however, is biologically impossible, and iodine deficiency causes severe developmental problems, including mental retardation. Read More

Ensuring the Efficacious Iron Fortification of Foods: A Tale of Two Barriers.

Nutrients 2022 Apr 12;14(8). Epub 2022 Apr 12.

Institute of Food, Nutrition and Health, ETH Zurich, Schmelzbergstrasse 7, CH 8092 Zurich, Switzerland.

Iron fortification of foods has always been a challenge. This is because iron fortification compounds vary widely in relative absorption; because many foods undergo unacceptable changes in color or flavor from the addition of iron; and because many of the iron-fortified foods contain potent inhibitors of iron absorption. These technical barriers have largely been overcome, and efficacious iron-fortified foods, that maintain or improve the iron status of women or children in long-term feeding studies, can be designed.

Comparative Analysis of Five Correction Methods for Thyroid Volume by Ultrasound and Their Recommended Reference Values in Chinese Children Aged 8-10 Years.

Br J Nutr 2022 Apr 13:1-28. Epub 2022 Apr 13.

Key lab of Etiology and Epidemiology, National Health Commission & Education Bureau of Heilongjiang Province (23618504) & Key Laboratory of Trace Elements and Human Health, Centre for Endemic Disease Control, Chinese Centre for Disease Control and Prevention, Harbin Medical University, Harbin, 150081.

Considering the influence of body's growth and development on thyroid volume (TVOL), whether five existed corrected methods could be applied to correct TVOL remains unclear, in terms of Chinese children's increased growth and development trends. This study aimed to compare the applicability of five correction methods for TVOL: Body Surface Area corrected Volume (BSAV), Body Mass Indicator corrected Volume (BMIV), Weight and Height corrected Volume Indicator (WHVI), Height corrected Volume Indicator 1 (HVI1) and Height corrected Volume Indicator 2 (HVI2); to establish the reference values for correction methods. The data of Iodine Nutrition and Thyroid Function Survey was used to analyse the differences in TVOL between normal and abnormal thyroid function children. Read More

Biofortification: Effect of Iodine Fortified Food in the Healthy Population, Double-Arm Nutritional Study.

Front Nutr 2022 23;9:871638. Epub 2022 Mar 23.

Department of Biological, Chemical and Pharmaceutical Sciences and Technologies, University of Palermo, Palermo, Italy.

It is estimated that one-third of the world's population lives in areas where iodine (I) is scarce and its deficiency is responsible for many related disorders, such as goiter, reproductive failure, hearing loss, growth impairment, congenital I deficiency syndrome, and numerous kinds of brain injury. Mineral deficiencies can be overcome dietary diversification and mineral supplementation. An alternative or even complementary way is represented by the intake of biofortified foods, which can tackle this lack of micronutrients. Read More

Iodine fortification of plant-based dairy and fish alternatives - the effect of substitution on iodine intake based on a market survey in the UK.

Br J Nutr 2022 Apr 4:1-28. Epub 2022 Apr 4.

Department of Nutritional Sciences, Faculty of Health and Medical Sciences, University of Surrey, Guildford GU2 7XH, United Kingdom.

Iodine deficiency has been demonstrated in UK women, which is of concern as iodine is required for fetal brain development during pregnancy. Plant-based diets are increasingly popular, especially with young females, which may affect iodine intake as the main dietary sources are dairy and fish; plant-based products are naturally low in iodine. We, therefore, aimed to (i) assess the iodine fortification of milk-, yoghurt-, cheese- and fish-alternative products available in UK supermarkets and (ii) model the impact that substitution with such products would have on iodine intake using portion-based scenarios.
