Filter by:Salt is one of the very few regularly purchased food item in all socioeconomic classes including poor remote areas with subsistence farming. Therefore, it is a promising vehicle for fortification with micronutrients, such as iodine, iron, vitamin A, to alleviate the burden of micronutrient deficiencies. However, ensuring the bioavailability of iron and the sensory quality in fortified salt is difficult. Water-soluble iron compounds, such as ferrous sulphate FeSO4, are the most bioavailable, but they react with moisture and impurities in salt, and cause unacceptable changes in colour. Encapsulation can reduce iron-mediated colour change in fortified salt without significantly compromise bioavailability. In the present project we aim to investigate the iron bioavailability from salt fortified with FeSO4 using a new encapsulation type based on hyaluronic acid (HA) and a polymer from the eudragit family (EPO).
Iron deficiency is a highly prevalent nutrient deficiency which is a public health problem, especially in developing countries. There are several strategies to correct iron deficiency in populations: besides supplementation with tablets, one of the most sustainable and effective strategies on medium term has been iron fortification, the addition of iron to regularly consumed foods. In fortification, the chemical nature of the compound to be added plays an important role: depending on the compound sensory qualities of the fortified foods can vary as well as the iron absorption. Iron pyrophosphate (FePP) and ferrous sulfate (FeSO4) are two commonly used iron fortification compounds in foods such as rice, breakfast cereals, pasta, flour and others. We want to test the effect of addition a food stabilizer on the absorption of ferric pyrophosphate (FePP) and ferrous sulfate (FeSO4) when added to bouillon, as was recently suggested by in vitro experiments in the laboratory.
Many Indonesian infants are already iron deficient before they reach the age of six months, which also determines the high prevalence of anemia among under-five children. Iron deficiency ultimately leads to anemia, and there is clear evidence that iron deficiency anemia during early childhood has a marked negative effect on child development and cognitive function (Lozoff et al.1991; Idjradinata & Pollitt, 1993). This negative impact on childhood development is one of the main reasons why iron deficiency during infancy should be prevented or treated. Since diets low in iron is usually also low in zinc, zinc deficiency --which has negative consequence on growth-- is common in iron deficiency area. In Southeast Asia, the condition is exacerbated by the rich phytate content in the complementary foods which inhibits the absorption of iron as well as zinc (Gibson, 1994). Thus, combining both iron and zinc, hence, is expected to decrease both iron and zinc deficiencies and hence improve growth and development of the children. Recently, there has been an emerging view which looks at the two-way relationship between nutrition, health, and psychosocial well-being. This concept is supported by studies on "positive deviance", a term used to refer to children who grow and develop well in impoverished environments where most children are victims of malnutrition and chronic illness (Zeitlin et al., 1990). The mechanism which helps to explain how psychosocial factors, such as the affect between mother and child, are associated with adequate growth and development: 'Psychological stress has a negative effect on the use of nutrients whereas psychological well-being stimulates the secretion of growth-promoting hormones. Pleasantly stimulating interactions can enhance the child's tendency to exercise its developing organ systems and hence to utilize nutrients for growth and development'. Understanding how the psychosocial environment can promote or inhibit the benefit of supplementation intervention is necessary in order to have a better way of setting about providing supplements. In fact, many supplementation programs do not incorporate complementary program elements that would help to improve the health and psychosocial development of children at the same time that they improve nutritional status' (Myers, 1995). Looking from this perspective, not only will supplementation benefit the psychosocial development but also the psychosocial environment can promote the benefit of the supplementation on the nutritional status and developmental outcomes of infants. The purpose of the study is to investigate whether multi-micronutrient supplementations (zinc+iron, zinc+iron+vit.A) have positive effect on infants' growth and developmental outcomes, and whether the effect is modified by psychosocial care.
Iron deficiency is common in cardiorespiratory diseases and appears to contribute to a worse outcome. This human physiology study will examine the extent to which human skeletal muscle metabolism and exercise physiology are impaired by iron deficiency.
The study is designed to assess the bioavailability of iron from 4 different iron fortified savoury food products
Multicentre randomized controlled trial to evaluate the optimal treatment for patients who developed an iron deficiency after Roux-en-Y Gastric bypass.
Investigation of Iron Bioavailability from extruded rice grains fortified with Ferric Pyrophosphate alone or in combination with different Zinc Compounds; Ferrous Sulfate serves as a Reference.
The prevalence of iron deficiency in blood donors has been demonstrated to be a direct consequence of repeat blood donations. Given the adverse effects of iron deficiency, it is priority to implement programs to remediate iron deficiency issues associated with blood donations. To explore this issue, the study's aims to: 1. Determine whether regular blood donors provided with accurate information about their iron status and written recommended courses of action will take steps to prevent/mitigate iron deficiency on their own without being given iron supplements by the blood center; and 2. Determine if two different amounts of iron provided by the blood center will prevent/mitigate iron deficiency in regular blood donors. To conduct this randomized, placebo controlled study, participant donors will be assigned to one of two arms and followed for a 24 month period. Each subject will provide additional blood samples of 7 ml and 4.5 ml at each study visit for the purpose of tracking hemoglobin (Hgb), ferritin, soluble transferrin receptor (sTfR), and hematology laboratory results. Under the two study arms, subjects are to be randomized into one of the following five blinded categories: - Receive a thank you letter after each blood donation. - Receive a letter informing them of their ferritin result at each visit, along with recommendations for blood donation. - Receive pills to take daily that contain no iron (a placebo or inert pill). - Receive pills to take daily that contain 19 mg of iron (the typical amount in a multivitamin with iron). - Receive pills to take daily that contain 38 mg iron (the typical amount in an over-the-counter iron supplement).
INTRODUCTION Exclusively breastfed infants are at risk of iron deficiency. American Academy of Pediatrics (AAP) recommends iron supplementation in exclusively breastfed infants beginning at 4 months of age. Uncertainty exists regarding the effects of iron supplementation during infancy on neurodevelopmental outcomes in the absence of anemia. AIM To establish whether psychomotor and mental development is influenced by early iron supplementation in healthy, non-anemic, exclusively or predominantly breastfed infants. METHODS Healthy term newborns will be recruited shortly after birth. If predominantly breastfed (>50% daily feedings) and non-anemic at 4 months, they will be randomized to receive either an iron supplement (approx.1mg/kg/day) or placebo until 9 months of age. Participants will be assessed with use of Bayley Scales of Infant and Toddler Development (Bayley III) at 12, 24 and 36 months of age.
In this study, iron- and zinc-biofortified pearl millet will be fed to young children in Mumbai, Maharashtra, India over a period of nine months to measure growth and immune function in comparison to children receiving non-biofortified pearl millet.
