Iron deficiency anemia (IDA) is a significant challenge in developing countries. It increases the risk of premature delivery and low birth weight. In children, IDA retards growth, impairs cognitive performance, and reduces physical activity. It also accelerates the mortality and morbidity rate in women. The key factors responsible include dietary ...

A possible role of the macronutrients and the basic elements of carbohydrates (glucose administration or depletion), proteins (amino acids such as tryptophan and tyrosine), and fat (unsaturated fatty acids) was recently proposed for age-related changes of cognitive function, and the cognitive decline of degenerative (AD) or vascular origin. The availability ...

Phosphorus release to runoff varies widely for different land-applied organic P sources even when spread at equivalent total P rates. To address this variability, some P site indices include tabulated P source coefficients (PSCs) for differential weighting of applied P materials based on their runoff enrichment potential. Because runoff P ...

The true extent of nutritional iron deficiency (ID) in childhood is unclear because of uncertainty over its definition and the insensitivity of markers of ID. The major cause is likely to be the excessive and early use of cow's milk. Recent neurophysiological observations support the many field studies correlating ID ...

Nitric oxide has been extensively studied as a noninvasive marker of airway inflammation. Assuming that bronchoscopy can produce not only systemic but also local inflammatory response, we hypothesized that bronchofiberoscopy can be responsible for an increase in nitric oxide synthesis with resulting increase in fractional concentration of exhaled nitric oxide ...

Asteroidal material, delivered to Earth as meteorites, preserves a record of the earliest stages of planetary formation. High-precision oxygen isotope analyses for the two major groups of stony-iron meteorites (main-group pallasites and mesosiderites) demonstrate that each group is from a distinct asteroidal source. Mesosiderites are isotopically identical to the howardite-eucrite-diogenite ...

Polyphenols including tannins and flavonoids are common in plant foods. While tannins may be deleterious to animals, flavonoids can have beneficial effects on the cardio-vascular system. Since salivary proteins can form complexes with polyphenols and thereby interfere with their intestinal absorption, the effect of salivary proteins on transport of tannins ...

Since the last century, fortified and enriched foods are products whose original composition has been modified-through addition of essential nutrients-to satisfy specific population needs. For the fortification of foods to have a positive impact on nutritional status, the micronutrients added must be well absorbed and utilized by the organism (bioavailability). ...

Campylobacter jejuni is a food-borne bacterial pathogen that possesses two distinct hemoglobins, encoded by the ctb and cgb genes. The former codes for a truncated hemoglobin (Ctb) in group III, an assemblage of uncharacterized globins in diverse clinically and technologically significant bacteria. Here, we show that Ctb purifies as a ...

Micronutrient deficiencies represent a largely invisible, but often devastating, form of malnutrition that is particularly prevalent among WFP's beneficiary populations already lacking sufficient food. Known effects of micronutrient deficiencies include impaired physical and mental growth among children, iron-deficiency anemia, maternal mortality, low adult labor productivity and blindness. WFP makes important, ...

The adult human contains 2-3g of zinc, about 0.1% of which are replenished daily. On this basis and based on estimates of bioavailability of zinc, dietary recommendations are made for apparently healthy individuals. Absent chemical, functional, and/or physical signs of zinc deficiency are assumed indicative of adequacy. More specific data ...

Plant sterol-enriched foods are an effective dietary adjuvant in reducing cardiovascular risk by lowering total cholesterol and low density lipoprotein-cholesterol (LDL-C) in serum by up to approximately 15%. The mechanism of action of plant sterols is different from those of 3-hydroxy-3-methylglutaryl coenzyme A inhibitors (statins) and thus their effect is ...

The oxidation of protocatechuic acid (PA), a typical phenol-type compound present in food processing wastewater, has been carried out by means of Fenton's reagent. Both the H2O2 and Fe(II) initial concentrations increase the PA degradation rate. Temperature also enhances the PA conversion when raised from 283 to 313 K, a ...

Insufficient ascorbate intake causes scurvy in certain species. Beyond its known functions, it has been suggested that ascorbate participates in oxidative protein folding in the endoplasmic reticulum (ER). Because redox imbalance in this organelle might cause ER stress and apoptosis, we hypothesized that this might contribute to the pathology of ...

Iron deficiency, a global health problem, impairs reproductive performance, cognitive development, and work capacity. One proposed strategy to address this problem is the improvement of dietary iron bioavailability. Knowledge of the molecular mechanisms of iron absorption is growing rapidly, with identification of mucosal iron transport and regulatory proteins. Both body ...

Three factors determine how much iron will be absorbed from a meal. They are the physiological mechanisms that regulate uptake by and transfer through the enterocytes in the upper small intestine, the quantity of iron in the meal, and its availability to the cellular iron transporters. Established methods exist for ...
