Salt-Containing Recipes in Popular Magazines with the Highest Circulation in the United States Do Not Specify Iodized Salt in the Ingredient List.

Iodine deficiency is a public health problem in the US, with the iodine status of women of reproductive age decreasing in recent years. This may be attributable to voluntary salt iodization in the US. Magazines, a common source of recipes and nutritional information, may influence salt use and iodine intake. The aim of this study is to assess whether the magazines with the highest circulation in the US include recipes that contain salt and, if so, whether they specify "iodized salt" in the recipes. Recipes in eight of the top ten magazines by circulation in the US were examined. Standardized information was collected on the presence and type of salt in recipes in the last 12 issues reviewed per magazine. About 73% of the 102 issues reviewed contained recipes. A total of 1026 recipes were surveyed for salt; 48% of the recipes listed salt as an ingredient. None of the 493 recipes containing salt specified iodized salt as the type of salt to be used. About half of the recipes in the last 12 issues of popular magazines published in the US included salt in the ingredient list; however, none recommend the use of iodized salt. There is potential for editorial changes among magazines to call for iodized salt in recipes, which may further prevent iodine deficiency in the US.

A Practical Guide to Adjust Micronutrient Biomarkers for Inflammation Using the BRINDA Method.

The Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) research group was formed over a decade ago to improve the interpretation of micronutrient biomarkers in settings with inflammation. The BRINDA inflammation adjustment method uses regression correction to adjust for the confounding effects of inflammation on select micronutrient biomarkers and has provided important insights to micronutrient research, policy, and programming. However, users may face challenges when applying the BRINDA inflammation adjustment methods to their own data due to varying guidance on the adjustment approach for different biomarkers and the need to develop statistical programming to conduct these analyses. This may result in lost opportunities to have results of micronutrient data readily available during critical decision-making periods. Our research objectives are to 1) provide an all-in-one summary of the BRINDA method in adjusting multiple micronutrient biomarkers for inflammation, 2) evaluate whether malaria as a binary variable should be included in the BRINDA inflammation adjustment method, and 3) present standardized and user-friendly BRINDA adjustment R package and SAS macro. This paper serves as a practical guidebook for the BRINDA inflammation adjustment approach and aids users to use the BRINDA R package and SAS to streamline their analyses.
