“…It also has deleterious effects on the immune system, favoring pathologies related to the skin, lungs, and gastrointestinal tract that can persist until adult life [108]. Thus, zinc deficiency is also associated with negative outcomes such as increased morbimortality at birth, increased severity of infectious diseases, stunted growth, and physiological alterations (anorexia, hypogonadism, hypogeusia (reduced sense of taste), dermatitis, dysfunctions of the immune system, and oxidative and neuropsychological damages) [109]. Zinc deficiency is also associated with diarrheic manifestations and predisposition to fever convulsions in children between 6 days and 6 months of age [110].…”

Minerals in Pregnancy and Their Impact on Child Growth and Development

During pregnancy, women undergo metabolic and physiological changes, and their needs are higher, to maintain growth and development of the fetus. If the nutritional status of the expectant mother is not satisfactory, some maternal and neonatal complications can occur. In the second and third trimester of pregnancy, there is a reserve of nutrients in the fetus that can be utilized after birth; thereby, children present an accelerated growth in the first years of life, which is a proven response to the available nutrition pattern. However, if such a pattern is insufficient, there will be deficits during development, including brain function. Therefore, despite many recent published works about gestational nutrition, uncertainties still remain on the mechanisms of absorption, distribution, and excretion of micronutrients. Further elucidation is needed to better understand the impacts caused either by deficiency or excess of some micronutrients. Thus, to illustrate the contributions of minerals during prenatal development and in children, iodine, selenium, iron, zinc, calcium, and magnesium were selected. Our study sought to review the consequences related to gestational deficiency of the referred minerals and their impact on growth and development in children born from mothers with such deficiencies

Mineral composition, chlorophyll fluorescence and zinc biofortification in Vigna unguiculata fertilized with bulk and nanoparticulate zinc oxides

Nanoparticulate materials have aroused growing commercial and scientific interests in several fields, including their use as fertilizer. Here, we evaluated the effects of a nanoparticulate zinc source (ZnO-NP), compared to bulk ZnO on biomass yield, mineral composition, chlorophyll fluorescence, and Zn concentration in cowpea (Vigna unguiculata) plants and grains. The two sources of Zn were applied to soil in five rates (0, 100, 300, 500, and 800 mg dm −3 ) to cover the micronutrient's sufficiency and toxicity ranges. Plants were grown for 110 days and concentrations of N, P, K, Fe, Cu, and Mn were determined in roots and shoots, while Zn and Fe were also measured in grains. The chlorophyll fluorescence and concentrations of the chlorophyll a, chlorophyll b, carotenoids, and xanthophyll pigments in leaves were measured. The results showed that at the rate of 100 mg dm −3 ZnO, the bulk and nanoparticulate Zn oxides adequately supplied the Zn concentrations required by cowpea, promoting increases in shoot and grain biomass. At doses higher than 300 mg dm −3 of ZnO, however, bulk ZnO application caused more significant toxicity in plants, promoting decreased biomass and damage to the photosynthetic apparatus. The chlorophyll fluorescence parameters were efficient in predicting the damage to cowpea plants' photosynthesis before the appearance of visual symptoms. The sources were similar in the increase of Zn in the grains and the reduction of the Fe concentrations; therefore, Zn biofortification programs would not benefit from nanoparticulate sources of the element via soil in the conditions of the present study.
