Introduction: Population risk for neural tube defects (NTDs) can be determined using red blood cell (RBC) folate. However, a paucity of biomarker and surveillance data among non-lactating, non-pregnant women of reproductive age (NPWRA) from Africa limits accurate assessment. Our study assessed folate and vitamin B12 status among non-lactating NPWRA and predicted population risk of NTDs in Tanzania.

Introduction: Micronutrient deficiencies are common among women of reproductive age (WRA) and children in Senegal. Large-scale food fortification (LSFF) can help fill gaps in dietary intakes.
Methods: We used household food consumption data to model the contributions of existing LSFF programs (vitamin A-fortified refined oil and iron and folic acid-fortified wheat flour) and the potential contributions of expanding these programs to meeting the micronutrient requirements of WRA (15-49 years) and children (6-59 months).

Neural tube defects (NTDs) are malformations of the central nervous system that represent the second most common cause of congenital morbidity and mortality, following cardiovascular abnormalities. Maternal nutrition, particularly folic acid, a B vitamin, is crucial in the etiology of NTDs. FA plays a key role in DNA methylation, synthesis, and repair, acting as a cofactor in one-carbon transfer reactions essential for neural tube development.

Myelomeningocele (MMC) is the most severe and disabling form of spina bifida with chronic health multisystem complications and social and economic family and health systems burden. In the present study, we aimed to investigate the genetic risk estimate for MMC in a cohort of 203 Mexican nuclear families with discordant siblings for the defect. Utilizing a custom Illumina array, we analyzed 656 single nucleotide polymorphisms (SNPs) of 395 candidate genes to identify a polygenic risk profile for MMC.

Background: This work focused on the study of the indirect fortification of Mexican tortillas made from nixtamalized masa (NM) with nixtamalized commercial corn flour (NCC-F) fortified with Zn, Fe, vitamins and folic acid.
Methods: The chemical proximate values (CPV), ash content, mineral composition by inductively coupled plasma, in vitro protein digestibility (PD), protein digestibility-corrected amino acid score (PDCAAS), the total starch content, the resistant starch (RS) content in nixtamalized corn tortillas (NC-T) and nixtamalized commercial corn flour tortillas (NCCF-T) and the contribution of tortillas prepared with a mixture of NM and NCC-F (75:25 and 50:50, NM:NCC-F) to the recommended dietary intake (RDI) of minerals and vitamins were determined.
Results: No significant differences ( < 0.
