Background: Poor nutritional quality of complementary foods often limits growth. Animal source foods, such as milk or meat, are often unaffordable. Local affordable alternatives are needed. Objective: We evaluate the efficacy of 2 newly developed, rice-based complementary food products: WinFood (WF) with small fish and edible spiders and WinFood-Lite (WF-L) fortified with small fish, against 2 existing fortified corn-soy blend products, CSB+ (purely plant based) and CSB++ (8% dried skimmed milk). Design: In total, 419 infants aged 6 mo were enrolled in this randomized, single-blinded study for 9 mo, designed primarily to assess increments in fat-free mass by a deuterium dilution technique and change in plasma ferritin and soluble transferrin receptor. Secondary endpoints were changes in anthropometric variables, including kneeheel length. Data were analyzed by the intention-to-treat approach. Results: There was no difference in fat-free mass increment in WF or WF-L compared with CSB+ [WF: +0.04 kg (95% CI: 20.20, 0.28 kg); WF-L: +0.14 kg (95% CI: 20.10, 0.38 kg)] or CSB++ [WF: 20.03 kg (95% CI: 20.27, 0.21 kg); WF-L: +0.07 kg (95% CI: 20.18, 0.31 kg)] and no effect on iron status. The 1.7-mm (95% CI: 20.1, 3.5 mm) greater increase in knee-heel length in WF-L than in CSB+ was not significant. Conclusions: No difference was found between the locally produced products (WF and WF-L) and the CSBs. Micronutrient fortification may be necessary, and small fish may be an affordable alternative to milk to improve complementary foods. The dietary role of edible spiders needs to be further explored.

Background: Thiamine deficiency is common in parts of Asia and causes beriberi. Pharmacokinetics of thiamine in deficient populations are unknown. Objective: We characterized thiamine pharmacokinetics in Cambodian mothers and their breastfed infants. Design: Total plasma thiamine, whole-blood thiamine diphosphate (TDP), and breast milk total thiamine were measured in 16 healthy Cambodian mothers and their infants before and after mothers received oral thiamine hydrochloride (100 mg for 5 d). Assays were also performed in 16 healthy American mothers. Results: On day 1, Cambodian mothers were thiamine deficient, with median (range) total plasma thiamine and TDP concentrations of 2.4 nmol/L (0-4.4 nmol/L) and 58.0 nmol/L (27-98 nmol/L), respectively. After a single oral dose, the mean ± SD maximal concentration of thiamine and net area under the thiamine concentration-time curve were 73.4 ± 45.6 nmol/L and 465 ± 241 h ⋅ nmol ⋅ L-1. Day 6 median maternal total plasma thiamine and TDP concentrations were normal [18.6 nmol/L (13.4-25.3 nmol/L) and 76.5 nmol/L (48-107 nmol/L), respectively; P ≤ 0.001 compared with day 1]. Median Cambodian total breast milk thiamine concentration increased from 180 nmol/L (85-359 nmol/L) on day 1 to 403 nmol/L (314-415 nmol/L) on day 2 and 503 nmol/L (360-808 nmol/L) on day 6; the corresponding American breast milk value was 500 nmol/L (114-622 nmol/L). Median Cambodian infant total plasma thiamine and TDP concentrations increased from 3.0 nmol/ L (0-7.3 nmol/L) and 38.5 nmol/L (23-57 nmol/L), respectively, on day 1 to 5.6 nmol/L (0-9.7 nmol/L) and 45.5 nmol/L (32-70 nmol/ L), respectively, on day 6. Conclusions: Thiamine-deficient Cambodian mothers effectively absorb oral thiamine, with sharp increases in breast milk thiamine concentrations, but their breastfed infants remain thiamine deficient after 5 d of maternal supplementation. Longer-term maternal supplementation may be necessary to correct thiamine deficiency in breastfed infants. This trial was registered at clinicaltrials.gov as NCT01864057. [ABSTRACT FROM AUTHOR]
