Vitamin deficiency affects up to 50% of the world's population, disproportionately impacting on developing countries where populations endure monotonous, cereal-rich diets. Transgenic plants offer an effective way to increase the vitamin content of staple crops, but thus far it has only been possible to enhance individual vitamins. We created elite inbred(More)
Breast milk (BM) is considered as a reference for infant nutrition. The role of bioactive components, such as cytokines, hormones, growth factors (GFs) and fatty acids (FAs) is poorly known, but they might be implicated in immune response development. The aim of this study was to identify the lipid profile and the spectrum of cytokines and neuronal GF in BM(More)
Selenium is an important trace element that was considered toxic for humans and animals for a long time. The best known biochemical role of selenium is, as a selenocysteine residue, to be a part of the active site of the enzyme glutathione peroxidase (GSH-Px). The highest values of selenium have been found in protein foods (meat and fish); although selenium(More)
The aim of the present study was to compare the Fe, Zn, Cu, Ca and Mg contents and their in vitro availability in three meat-based weaning foods as a function of the meat cuts used in their formulation. The three meat cuts were yearling cow flank (YCF), mature cow flank(MCF) and mature cow mixed (MCM) cuts. The highest level of Fe (1.14 ± 0.31 mg/100 g) was(More)
Selenium (Se) concentration in 13 homogenised beikosts ("any additional food used in infant nutrition different from human milk and formulas") was investigated, as well as the influence of ingredients on Se concentration in three beikost types (meat, vegetables and fish). Levels of Se varied widely, ranging from 20 micrograms/kg d.w. for mixed vegetables to(More)
PURPOSE Tomato products are a dietary source of natural antioxidants, especially lycopene, which accumulates in the liver, where it exerts biological effects. Taking into consideration this fact, the aim of the present study was to ascertain the effect of tomato consumption on biomarkers and gene expression related to lipid metabolism in rats with induced(More)
The effects of cultivar, on-vine ripening, and year of harvest on the folate content of raw tomatoes were studied. Folate content in hot-break tomato puree (HTP) subjected to pasteurization at different temperatures and its evolution during the shelf life of tomato juice were also investigated. 5-Methyltetrahydrofolate (5-CH(3)-H(4)-folate) was the only(More)
The relationship between adequate folate intake, adequate serum levels, and lowering the risk of suffering from cardiovascular diseases, neural tube defects, neural illness and some kind of cancers have been widely studied. Because of the expected health benefits, the consumption of foods with high folate content or enriched foods is increasing. Therefore,(More)
Bioactive compounds and their relationship with antioxidant activity were determined in three tomato cultivars (Ronaldo, Siena and Copo) during vine ripening. The lycopene, chlorophyll (total, a and b), total phenolic, flavonoid, vitamin C and folate contents, and the antioxidant activity, by the ferric reducing/antioxidant power assay and the beta-carotene(More)
AIM To test the effect of the dephytinization of three different commercial infant cereals on iron, calcium, and zinc bioavailability by estimating the uptake, retention, and transport by Caco-2 cells. METHODS Both dephytinized (by adding an exogenous phytase) and non-dephytinized infant cereals were digested using an in vitro digestion protocol adapted(More)
