Placental adaptations to micronutrient dysregulation in the programming of chronic disease.

Poor nutrition during pregnancy is known to impair foetal development and increase the risk of chronic disease in offspring. Both macronutrients and micronutrients are required for a healthy pregnancy although significantly less is understood about the role of micronutrients in the programming of chronic disease. This is despite the fact that modern calorie rich diets are often also deficient in key micronutrients. The importance of micronutrients in gestational disorders is clearly understood but how they ...

Micronutrients Dietary Patterns associated with type 2 diabetes among women of the E3N-EPIC Cohort Study.

Micronutrients play a key role in type 2 diabetes, but methodological difficulties arise from their collinearity and interdependencies with foods. The objective of the present study is to identify micronutrient dietary patterns in the E3N-EPIC cohort and to investigate their association with type 2 diabetes risk.

Seed priming with iron and zinc in bread wheat: effects in germination, mitosis and grain yield.

Currently, the biofortification of crops like wheat with micronutrients such as iron (Fe) and zinc (Zn) is extremely important due to the deficiencies of these micronutrients in the human diet and in soils. Agronomic biofortification with Fe and Zn can be done through different exogenous strategies such as soil application, foliar spraying, and seed priming. However, the excess of these micronutrients can be detrimental to the plants. Therefore, in the last decade, a high number of studies focused on the ev...

Impact of Micronutrients on the Immune Response of Animals.

Vitamins and minerals (micronutrients) play an important role in regulating and shaping an immune response. Deficiencies generally result in inadequate or dysregulated cellular activity and cytokine expression, thereby affecting the immune response. Decreased levels of natural killer, granulocyte, and phagocytic cell activity and T and B cell proliferation and trafficking are associated with inadequate levels of micronutrients, as well as increased susceptibility to various adverse health conditions, includ...

Utilizing Dietary Micronutrient Ratios in Nutritional Research May be More Informative than Focusing on Single Nutrients.

The 2015 US dietary guidelines advise the importance of good dietary patterns for health, which includes all nutrients. Micronutrients are rarely, if ever, consumed separately, they are not tissue specific in their actions and at the molecular level they are multitaskers. Metabolism functions within a seemingly random cellular milieu however ratios are important, for example, the ratio of adenosine triphosphate to adenosine monophosphate, or oxidized to reduced glutathione. Health status is determined by si...

Renal cell carcinoma risk associated with lower intake of micronutrients.

Kidney cancer incidence in African Americans (AA) is higher than among European Americans (EA); reasons for this disparity are not fully known. Dietary micronutrients may have a protective effect on renal cell carcinoma (RCC) development by inhibiting oxidative DNA damage and tumor growth. We evaluated whether any micronutrient associations differed by race in the US Kidney Cancer Study. 1142 EA and AA RCC cases and 1154 frequency-matched controls were enrolled in a population-based case-control study betwe...

Trace metal metabolism in plants.

Many trace metals are essential micronutrients, but also potent toxins. Due to natural and anthropogenic causes, vastly different trace metal concentrations occur in various habitats, ranging from deficient to toxic levels. Therefore, one focus of plant research is on the response to trace metals in terms of uptake, transport, sequestration, speciation, physiological use, deficiency, toxicity, and detoxification. In this review, we cover most of these aspects for the essential micronutrients copper, iron, m...

Dietary antioxidant micronutrients alter mucosal inflammatory risk in a murine model of genetic and microbial susceptibility.

Inflammatory bowel diseases (IBD) are caused by the convergence of microbial, environmental, and genetic factors. Diet significantly alters these interactions by affecting both the host and microbiome. Using a mucosal inflammatory model that resembles the human condition of ileal pouchitis, we investigated the effects of Control (CONT) or Antioxidant (AOX) diet, containing pharmacologically relevant levels of 4 micronutrients, on disease risk in wild-type and IL-10-/- animals following surgical self-filling...

Alteration of crop yield and quality of wheat upon exposure to silver nanoparticles in a life cycle study.

Due to the rapid development of nanotechnology, metal-based nanoparticles (NPs) are inadvertently released into environment and may pose a potential threat to ecosystem. However, information for food quality and safety in NP treated crops is limited. In the present study, wheat (Triticum aestivum L.) was grown in different concentrations of Ag NP amended soil (20, 200, and 2000 mg•kg-1) for four months. At harvest, physiological parameters, Ag and micronutrients (Fe, Cu, and Zn) content, as well as amino ...

The nutritional status of the Spanish population, 1860-2010: an approach to gender and generational differences.

the main changes in the diet and the intake of energy and macronutrients as a result of the Nutritional Transition in Spain (NTS) are well known, but the intake of micronutrients and the overall nutritional status of the population are much less well known.

Identification of genomic regions associated with agronomic and biofortification traits in DH populations of rice.

Rice provides energy and nutrition to more than half of the world's population. Breeding rice varieties with the increased levels of bioavailable micronutrients is one of the most sustainable approaches to tackle micronutrient malnutrition. So, high zinc and iron content in the grain are primary targets in rice biofortification breeding. In this study, we conducted QTL mapping using doubled haploid (DH) populations, PSBRc82 x Joryeongbyeo and PSBRc82 x IR69428, phenotyped for agronomic traits and micronutri...

Overfed but undernourished: recognizing nutritional inadequacies/deficiencies in patients with overweight or obesity.

Overweight and obesity are highly prevalent throughout the world and can adversely affect the nutritional status of individuals. Studies have shown that many people with obesity have inadequate intake of iron, calcium, magnesium, zinc, copper, folate and vitamins A and B, likely as a result of poor diet quality. Nutritional inadequacies or deficiencies may also occur due to altered pharmacokinetics in the individual with obesity and due to interactions in those with overweight or obesity with various pharma...

Deficit of Magnesium and States of Hypercoagulation: Intellectual Analysis of Data Obtained From a Sample of Patients Aged 18-50 years From Medical and Preventive Facilities in Russia.

The states characterized by pronounced hypercoagulable components (deep vein thrombosis, cardio- and cerebro-vascular pathologies) are caused by multiple pathophysiological factors, including insufficient supply of magnesium (Mg) and other micronutrients.

Effect of high chronic intake of sucrose on liver metabolism in aging rats. Modulation by rutin and micronutrients.

High-sugar intake and senescence share common deleterious effects, in particular in liver, but combination of these two factors was little studied. Our aims were to examine the effect of a high-sucrose diet in liver of old rats and also the potential benefices of a polyphenol/micronutrient supplementation. Four groups of 22-month-old male rats fed during 5 months with a diet containing either 13 or 62% sucrose, supplemented or not with rutin, vitamin E, A, D, selenium, and zinc were compared. We measured l...

Effect of Antioxidant Supplementation on Total Antioxidant Status in Indian Children with Type 1 Diabetes.

Hyperglycemia results in the overproduction of free oxygen radicals that impair the endogenous antioxidant defenses. A randomized controlled trial was conducted to compare the effect of 3 months of antioxidant supplementation in the form of foods rich in micronutrients with pharmacological supplement on total antioxidant status of Indian children with type 1 diabetes. Ninety children with diabetes (mean age 11.5 ± 3.6 yrs, 37 boys) were randomly allocated to three groups: Group 1 (n = 31) = DM controls; ...

The present study aimed to evaluate associations between family and home-related factors and children's snack consumption. We explored associations within subgroups based on ethnic background of the child.

Serum magnesium, phosphorus, and calcium levels and subclinical calcific aortic valve disease: A population-based study.

Calcific aortic valve disease (CAVD) is the most common valve disease. Although micronutrients are known to contribute to cardiovascular disease, the relationship with CAVD remains poorly evaluated. We examined the association of serum levels of magnesium, phosphorus, and calcium with prevalence, incidence, and progression of aortic valve calcification (AVC).

Zinc, zinc nanoparticles and plants.

Zinc belongs to the mineral elements, the so-called micronutrients, which are essential for all types of plants. Embedding itself into the enzymes associated with proteosynthesis and energy processes, zinc is necessary for maintaining the integrity of biomembranes and also plays an important role in the development of seeds and generative organs. This review focuses on summarising the findings on the interaction of zinc and plants and translates into the knowledge of the effect of zinc nanoparticles on plan...

Paediatric Patients with Coeliac Disease on a Gluten-Free Diet: Nutritional Adequacy and Macro- and Micronutrient Imbalances.

A strict, lifelong gluten-free diet is the cornerstone for management of coeliac disease. Elimination of gluten from the diet may be associated with nutritional imbalance; however, the completeness of this diet in energy and macro- and micronutrients in children is not well described. Understanding the nutritional adequacy of the gluten-free diet in children during this critical period of growth and development when dietary intake is strongly influential is important.

Origin and diversification of winged bean (Psophocarpus tetragonolobus (L.) DC.), a multipurpose underutilized legume.

For many crops, research into the origin and partitioning of genetic variation is limited and this can slow or prevent crop improvement programs. Many of these underutilized crops have traits that could be of benefit in a changing climate due to stress tolerance or nutritional properties. Winged bean (Psophocarpus tetragonolobus (L.) DC.) is one such crop. All parts of the plant can be eaten, from the roots to the seeds, and is high in protein as well as other micronutrients. The goal of our study was to id...
