Background Recent evidence suggests that the vitamin A equivalency of beta-carotene from plant sources is lower than previously estimated. Objective We assessed the effect of 60 d of daily supplementation with 750 microg retinol equivalents (RE) of either cooked, puréed sweet potatoes; cooked, purée...

Background Maternal undernutrition and newborn stunting [birth length-for-age z score (LAZ) Objective The objective was to evaluate the effect of lipid-based nutrient supplements for pregnant and lactating women (LNS-PLs) on birth outcomes. Design We conducted a cluster-randomized effectiveness tria...

Human milk is the subject of many studies, but procedures for representative sample collection have not been established. Our improved methods for milk micronutrient analysis now enable systematic study of factors that affect its concentrations. We evaluated the effects of sample collection protocol...

Background Information is needed on the minimum energy density and feeding frequency of complementary foods that can provide adequate energy intakes (EIs) for healthy breastfed children. Objectives The objectives of the study were to evaluate the effects of various energy densities and feeding frequ...

We assessed the effect of daily consumption of orange-fleshed sweet potatoes (OFSP), with or without added fat, on the vitamin A (VA) status of Bangladeshi women with low initial VA status. Women (n = 30/group) received one of the following for 6 d/wk over 10 wk: 1) 0 μg retinol activity equivalents...

Information is needed on zinc absorption from grain cultivars having higher zinc content. Total absorbed zinc (TAZ) from mixed diets containing high-zinc rice (HZnR), conventional rice (CR), or CR plus zinc fortificant (CR+Zn) was measured. Forty-two nonmalnourished preschool-aged children were enro...

Background Information is needed to design studies of the effects of complementary feeding regimens on children's intakes of complementary foods (CFs) and breast milk. Objective We evaluated the effects of varied energy density of CFs on the time until stabilization of dietary intakes and on total d...

Little valid information is available on human milk nutrient concentrations, especially for micronutrients (MNs), and there are no valid reference values (RVs) across lactation. In this multi-center collaborative study, RVs will be established for human milk nutrients across the first 8.5 mo postpar...

Background The deuterated-retinol-dilution (DRD) technique provides a quantitative estimate of total body stores of vitamin A. However, it is not known whether the technique can detect changes in vitamin A pool size in response to different intakes of vitamin A. Objective Our objective was to determ...

The estimated average requirement (EAR) for vitamin A (VA) of adult males is based on the amount of dietary VA required to maintain adequate function and provide a modest liver VA reserve (0.07 μmol/g). In the present study, the paired-deuterated retinol dilution technique was used to estimate chang...

Background Children in resource-limited settings remain vulnerable to zinc deficiency and its consequences. Objectives To evaluate the effects of different doses, durations, and frequencies of zinc supplementation on the incidence of diarrhea and change in linear growth among young children. Methods...

Background: Pregnancy and childbirth complications and cesarean delivery are common in Bangladesh. Objective: We evaluated the effect of lipid-based nutrient supplements for pregnant and lactating women (LNS-PL) on pregnancy and childbirth complications and cesarean delivery. Methods: We conducted t...

BACKGROUND: Vitamin A (VA) stores are low in early infancy and may impair development of the immune system. OBJECTIVE: This study determined if neonatal VA supplementation (VAS) affects the following: 1) development of regulatory T (Treg) cells; 2) chemokine receptor 9 (CCR9) expression, which direc...

This second article in the series establishing reference values (RVs) for nutrients in human milk describes RVs for protein, carbohydrate, fat, and energy. To establish RVs, the mothers, infants, and lactation quality (MILQ) and early-MILQ studies collected human milk samples throughout the first 8....

Young children in resource-constrained settings are susceptible to zinc deficiency and its deleterious health effects. The objective of this secondary analysis was to evaluate the effects of the following six interventions on biomarkers of iron and zinc status among a subgroup of young children in D...
