Background: Adequate maternal iodine intake is important for fetal brain development. Based on iodine intakes of non-pregnant females of reproductive age from the Canadian Health Measures Survey (2016 -2017) it can be extrapolated that most pregnant females in Canada will not meet iodine requirements without supplementation.
Objectives: To assess iodine intakes of 500 pregnant, nulliparous females from Québec, Canada and report on use of multivitamin/mineral (MVM) supplements and coverage of iodized salt.

To analyze the iodine nutrition status and its related factors among adults aged 18 years and above in Zhejiang Province in 2022. A multistage stratified sampling method was used to select 4 320 adults aged 18 years and above from 16 on-site survey sites in Zhejiang Province for the study. A questionnaire was used to investigate the general demographic information and personal dietary characteristics of the study participants.

For rechargeable zinc-iodine batteries, the low electrical conductivity of iodine and the easy dissolution of polyiodide in the electrolyte need to be carefully managed to ensure efficient operation. Herein, we introduce an organic iodized salt, formamidinium iodide (CHNI), to modulate the solvation structure of iodide ion, aimed to improve the reaction kinetics of iodine for reversible redox conversion. The participation of formamidinium ion (FA) into solvation structure leads to the formation of the favorable FAIZn(HO) complex, facilitating easier desolvation for redox conversion with iodine.

While many cathode materials have been developed for mild electrolyte-based Zn batteries, the lack of cathode materials hinders the progress of alkaline zinc batteries. Halide iodine, with its copious valence nature and redox possibilities, is considered a promising candidate. However, energetic alkaline iodine redox chemistry is impeded by an alkali-unadapted I element cathode and thermodynamically unstable reaction products.

Universal salt iodisation (USI) plays an essential role in the provision of iodine (I) to populations worldwide. Countries adopting USI programmes, adhering to strict criteria laid down by expert organisations such as the Iodine Global Network, are estimated to have reduced the prevalence of I deficiency by 75% (protecting 720 million individuals worldwide). Despite this success, doubts have been raised as to the desirability of continuing such programmes because of (a) the need to reduce salt intake for cardiovascular prevention and (b) the induction of thyroid autoimmunity.
