age babies and stillbirths in women who may not have many micronutrients in their usual diets. Undernourished women can benefit from having dietary education sessions and, balanced energy and protein supplements. A review showed that dietary education increased the mother's protein intake and helped the baby grow more inside the womb. The balanced protein and energy supplement lowered risk of stillbirth and small babies and increased weight gain for both the mother and baby. Although more research is needed into the longer term effects on the mothers' and infants' health, the short term effects look promising. A review conducted in 2018 found that there was a slight benefit for lipid-based nutritional supplements (LNS) for newborn birth weight, length, small for gestational age and stunting when compared with iron-folic acid (IFA). In the same study IFA and multiple micro-nutrients (MMN) reduced maternal anemia better than LNS but care is advised in interpreting and applying the results due to review limitations. Prenatal vitamins typically contain increased amounts of folic acid, iodine, iron, vitamin A, vitamin D, zinc, and calcium over the amounts found in standard multi-vitamins. Currently there is insufficient evidence that zinc supplements during pregnancy result in improved neonatal or maternal outcomes. The World Health Organization does not routinely recommend zinc supplementation for all pregnant women. Approximately of calcium is accumulated during pregnancy, almost all of it in the fetal skeleton (25 g). For women with low calcium diets, there is low quality evidence to suggest that calcium supplementation during pregnancy may reduce the risk of preeclampsia. Low-quality evidence also suggests that calcium supplementation may reduce the risk of the mother having the baby before 37th week of pregnancy (preterm birth). The protective effect of calcium supplementation is not clear and there is not enough good quality to research to suggest best doses and timing of calcium supplementation. A mother's nutritional intake during pregnancy is believed to influence and possibly offer protective effects against the development of allergenic diseases and asthma in children. Maternal intake of vitamin D, vitamin E, and zinc have all been associated with a lower likelihood of wheezing in childhood, suggesting a protective effect. Additionally, maternal intake of omega-3 long chain polyunsaturated fatty acids (n-3 LC-PUFAs) has been associated with a reduced risk of development of eczema in childhood and reduced likelihood to for infants exhibit sensitivity to foods in the first year of life.
