A individualidade bioquímica é um pilar fundamental da nutrição funcional, que direciona condutas personalizadas para cada indivíduo. Esta edição traz uma revisão que tem como tema central a aplicação da nutrigenômica na determinação do melhor tipo de dieta, mostrando o impacto das variações genéticas nas nossas necessidades nutricionais individuais.
Contribuindo para a atualização e prática clínica dos nutricionistas em relação às doenças crônicas não transmissíveis, ...

Neurotoxicity from prenatal and postnatal exposure to methylmercury
Abstract
The extent to which postnatal methylmercury exposure contributes to neurobehavioral delays is
uncertain. Confounding may occur because the child's dietary exposure likely correlates with the
mother's. This conundrum was examined in the Faroese birth cohort 1 born in 1986–1987.
Exposure parameters included mercury concentrations in maternal hair at parturition, cord blood,
and child blood and hair at the age-7 clinical examination (N = 923). In regression analyses, the
child's current blood-mercury at age ...

Mercury contamination in Southern New England coastal fisheries and dietary habits of recreational anglers and their families: Implications to human health and issuance of consumption advisories
Abstract
Total mercury (Hg) was measured in coastal fishes from Southern New England (RI, USA), and Hg exposure was estimated for anglers and family members that consumed these resources. Fish Hg was positively related to total length (n = 2028 across 7 fish species), and interspecies differences were evident among legally harvestable fish. Many recreational anglers and their families experienced ...

Low-Level Toxic Metal Exposure in Healthy Weaning-Age Infants: Association with Growth, Dietary Intake, and Iron Deficiency
Abstract: Even low levels of toxic metal exposure (As, Cd, Hg, and Pb) in infancy might be
harmful to children’s development. This study investigated toxic metal exposure on healthy
weaning-age infants and its relationship with growth, diet, and iron/anemia status. The weight,
height, head circumference, whole blood levels of four toxic metals, hemoglobin, and serum ferritin
of healthy infants was measured. Among 210 infants with a median age of 11.4 months ...

Infant Exposure to Metals through Consumption of Formula Feeding in Mekelle, Ethiopia
This study aimed at determination of heavy metals (cadmium, lead, and zinc) in milk-based infant formulas collected fromMekelle, Ethiopia, and their associated health risks to the infants through consumption of these products. The infant feeding samples were dry-ashed in a muffle furnace followed by digestion in nitric acid and the resulting solutions were analyzed by flame atomic
absorption spectrophotometer. Cadmium was not detected in the samples while the levels of lead and zinc ranged fromnot ...

Identification of toxic metals in human embryonic tissues
A b s t r a c t
Introduction: The cause of a significant number of miscarriages remains unexplained. There is a need to identify the potential role of environmental, dietary and lifestyle factors in the risk of pregnancy loss. The present study was the first to investigate the content of miscarried embryonic material with respect to eight metals (aluminium, cadmium, chromium, copper, manganese,
nickel, lead and zinc).
Material and methods: Embryonic tissue samples (n = 20) were obtained from women undergoing misoprostol-i...

Heavy metal contamination of prenatal vitamins
AB S T R A C T
Prenatal vitamins are often consumed daily during gestation and postnatally for up to 18–24 months with the belief that supplementation achieves better outcomes. Detrimental effects of gestational exposure to adverse chemical agents are gathering increasing attention. This study was designed to assess toxic element contamination in prenatal supplements. Twenty-six commonly used prenatal vitamin brands including one prescription brand were collected from Canadian health-food outlets and pharmacies, and tested for toxic ...
