Micronutrient deficiencies remain common among women and children in Sub‐Saharan Africa (SSA); in pregnant/lactating women, the intakes of essential fatty acids may also be low. Enriching home‐prepared foods with small‐quantity lipid‐based nutrient supplements (SQ‐LNSs) is a promising new strategy of delivering additional micronutrients, essential fatty acids and good quality protein to women and children. This narrative review aimed to examine the impact of SQ‐LNSs supplementation among women and infants and young children in SSA, and to discuss the differential impact of SQ‐LNS consumption across different settings. Papers reporting randomized trials conducted in SSA in which apparently healthy women and/or ≥6‐mo‐old children received SQ‐LNSs were identified through electronic and manual searches. Prenatal SQ‐LNS consumption reduced the prevalence of low gestational weight gain in Ghana when compared with multiple micronutrients supplementation, and was associated with poorer iron/hemoglobin status when compared with iron‐plus‐folic acid supplementation. SQ‐LNSs received alone or as intervention package improved infant/child growth in two trials in Ghana and one trial each in Burkina Faso, Kenya, Zimbabwe and South Africa, but had no impact on growth in two trials in Malawi. SQ‐LNSs supplementation improved motor development in Ghana, Burkina Faso, Malawi, Kenya, and South Africa, but had no impact on language, socio‐emotional, and executive functions in Ghana and Malawi and on Griffiths' developmental scores in Malawi. SQ‐LNSs may contribute to improving child growth in SSA. More research is needed to determine the iron level in SQ‐LNSs effective for improving both maternal hemoglobin/iron status and birth outcomes. [ABSTRACT FROM AUTHOR]

The International Lipid‐Based Nutrient Supplements (iLiNS) Project began in 2009 with the goal of contributing to the evidence base regarding the potential of lipid‐based nutrient supplements (LNS) to prevent undernutrition in vulnerable populations. The first project objective was the development of acceptable LNS products for infants 6–24 months and for pregnant and lactating women, for use in studies in three countries (Burkina Faso, Ghana and Malawi). This paper shares the rationale for a series of decisions in supplement formulation and design, including those related to ration size, ingredients, nutrient content, safety and quality, and packaging. Most iLiNS supplements have a daily ration size of 20 g and are intended for home fortification of local diets. For infants, this ration size is designed to avoid displacement of breast milk and to allow for dietary diversity including any locally available and accessible nutrient‐dense foods. Selection of ingredients depends on acceptability of flavour, micronutrient, anti‐nutrient and essential fatty acid contents. The nutrient content of LNS designed to prevent undernutrition reflects the likelihood that in many resource‐poor settings, diets of the most nutritionally vulnerable individuals (infants, young children, and pregnant and lactating women) are likely to be deficient in multiple micronutrients and, possibly, in essential fatty acids. During ingredient procurement and LNS production, safety and quality control procedures are required to prevent contamination with toxins or pathogens and to ensure that the product remains stable and palatable over time. Packaging design decisions must include consideration of product protection, stability, convenience and portion control. [ABSTRACT FROM AUTHOR]
