Published in Current Nutrition Reports, on the 5th of July, Santos et al conducted a review on the implementation and evaluation of salt reduction interventions in Low-and middle-income countries (LMICs). The review included articles related to salt reduction interventions between 2013 and 2020. Overall, the review included 32 studies, from 137 LMICs, finding that most interventions focused on education, food reformulation and salt substitution, and most of the interventions were multi-faceted. For studies that reported outcomes related to salt intake, the majority showed a positive effect of the interventions, however many of the studies were small and were targeted at specific groups. Authors concluded that there is evidence of effective salt reduction interventions in LMICs, however a focus on supporting scale-up of these interventions is needed.
