Collaborative Study for Iodine Monitoring in Mandatory Direct-Iodized Sauce in Thailand.

Direct iodization in fish sauce, soy sauce, and seasoning sauces plays a crucial role in optimizing the iodine intake of Thailand's people. However, determining the iodine content to ensure that these sauces meet the standard of Thailand's Food and Drug Administration (FDA) is challenging. In this study, all local laboratories equipped with inductively coupled plasma-mass spectrometry (ICP-MS) and with experience in iodine analysis by any analytical method were invited to participate in a hands-on training workshop and two rounds of interlaboratory comparison.

Breast Milk Retinol Concentrations Reflect Total Liver Vitamin A Reserves and Dietary Exposure in Thai Lactating Women from Urban and Rural Areas.

Background: Measuring vitamin A (VA) status during lactation is required to inform dietary recommendations. Limited data exist on VA stores in women.

Objectives: Our objective was to assess VA status in lactating Thai women by measuring total body VA stores (TBSs), serum and breast milk retinol concentrations, and dietary intake.
