Iodine is an essential micronutrient required for normal growth and neurodevelopment; thus, an adequate intake of iodine is particularly important for pregnant and lactating women, and throughout childhood. Low levels of iodine in the soil and groundwater are common in many parts of the world, often leading to diets that are low in iodine. Widespread salt iodization has eradicated severe iodine deficiency, but mild-to-moderate deficiency is still prevalent even in many developed countries. To understand patterns of iodine intake and to develop strategies for improving intake, it is important to characterize all sources of dietary iodine, and national databases on the iodine content of major dietary contributors (including foods, beverages, water, salts, and supplements) provide a key information resource...

Background and Objectives: The Chinese population typically has inadequate folate intake and no mandatory folic acid fortification. Methylenetetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) are the two key regulatory enzymes in the folate/homocysteine (Hcy) metabolism. Hcy has been implicated in the pathogenesis of cardiovascular disease. We conducted a meta-analysis to assess whether the MTHFR gene A1298C and the MTRR gene A66G polymorphisms affect Hcy levels in the Chinese population...

Jannik Nedergaard Pedersen, Henrik V Sørensen, Daniel E Otzen
α-Lactalbumin (α-LA) is the second most abundant bovine whey protein. It has been intensively studied because of its readiness to populate the molten globular (MG) state, a partially folded state with native levels of secondary structure but loss of tertiary structure. The MG state of α-LA exposes a significant number of hydrophobic patches that could be used to bind and stabilize small hydrophobic molecules such as vitamin D3 (vitD). Accordingly, we tested the ability of α-LA to stabilize vitD in a pH interval from 7...

Serum methylmalonic acid (MMA) is elevated in vitamin B-12 deficiency and in kidney dysfunction. Population reference values for serum MMA concentrations in post-folic acid fortification period are lacking. Aims of this study were to report the population reference values for serum MMA and to evaluate the relation between serum MMA and sex, age, race-ethnicity, kidney dysfunction and vitamin B-12. We used data from three National Health and Nutrition Examination Surveys, 1999-2000, 2001-2002 and 2003-2004 conducted after folic acid fortification commenced (n = 18,569)...

BACKGROUND: Undernutrition affects over 44% of hospitalised older people, who often dislike oral nutritional supplements (ONS). This review summarises the evidence for an alternative strategy, using energy and protein dense meals (via fortification) or snacks (supplementation) to increase the dietary energy and protein intake of older inpatients. METHODS: A search was conducted through PubMed, EMBASE, CINAHL and the Cochrane database of systematic reviews (May 1996 to May 2016) that used fortification or supplementation to increase the energy or protein intake of patients (mean age ≥60 years) in hospitals or rehabilitation centres...

Low 25-hydroxyvitamin D (25(OH)D) and elevated C-reactive protein (CRP) concentrations are independently associated with adverse health outcomes, including cardiovascular disease (CVD). Although an inverse association between these factors has been described, the underlying mechanisms remain unknown. We postulate that environment-gene interactions, through which 25(OH)D interacts with single nucleotide polymorphisms (SNPs) within the CRP gene, modulate CRP; that certain CRP genotypes predispose individuals to a co-phenotype of low 25(OH)D and elevated CRP concentrations; and that this co-phenotype is associated with higher CVD risk...

BACKGROUND: Progresses in childhood cancer treatment, diagnosis, and management have resulted in childhood cancer survival rates of over 80%. However, this therapeutic success comes with a heavy price: two-thirds of childhood cancer survivors will be affected by further complications, including cardiovascular and metabolic diseases. Adequate nutrition during cancer treatment is essential to ensure the child's optimal development, improve tolerance to treatments, and can contribute to lower the risk of developing cardiometabolic diseases...

BACKGROUND: Fortification of human milk is a standard practice for feeding very low birth weight infants. However, preterm infants often still experience suboptimal growth and feeding intolerance. New fortification strategies and different commercially available fortifiers have been developed. Commercially available fortifiers are constituted by a blend of ingredients from different sources, including plant oils and bovine milk proteins, thus presenting remarkable differences in the quality of macronutrients with respect to human milk...

BACKGROUND: Iron food fortification and oral iron formulations are frequently limited by poor absorption, resulting in the widespread use of high-dose oral iron, which is poorly tolerated. METHODS: We evaluated novel iron-denatured whey protein (Iron-WP) microspheres on reactive oxygen species (ROS) and viability in gut epithelial (HT29) cells. We compared iron absorption from Iron-WP versus equimolar-dose (25 mg elemental iron) ferrous sulphate (FeSO4) in a prospective, randomised, cross-over study in fasting volunteers (n = 21 per group) dependent on relative iron depletion (a ferritin level ≤/>30 ng/mL)...

PURPOSE: Fortification of foods with vitamin D may be a population-based solution to low vitamin D intake. We performed modelling of vitamin D from diet, fortified foods and supplements in a population of Danish women 18-50 years, a risk group of vitamin D deficiency, to inform fortification policies on safe and adequate levels. METHODS: Based on individual habitual dietary vitamin D intake of female participants from the Danish National Survey of Dietary Habits and Physical Activity (DANSDA) (n = 855), we performed graded intake modelling to predict the intake in six scenarios increasing the vitamin D intake from a habitual diet without fish to habitual diet including fish, fortified foods and supplements (40/80 µg)...

Food fortification through the increase and/or modulation of bioactive compounds has become a major goal for preventing several diseases, including cancer. Here, strawberry lines of cv. Calypso transformed with a construct containing an anthocyanidin synthase (ANS) gene were produced to study the effects on anthocyanin biosynthesis, metabolism and transcriptome. Three strawberry ANS transgenic lines (ANS L5, ANS L15 and ANS L18) were analysed for phytochemical composition and total antioxidant capacity (TAC), and their fruit extracts assessed for cytotoxic effects on hepatocellular carcinoma...

Feruloylated oligosaccharides (FOs) have been approved by the US Food and Drug Administration for addition to baked goods. This work investigated the effect of FOs on the formation of endogenous contaminants, antioxidant properties, appearance and texture of biscuits. FOs inhibited the formation of fluorescent AGEs (advanced glycation end-products), protein oxidation products, and dicarbonyl compounds in a dose-dependent manner. Addition of 10 mg/g FOs decreased the levels of fluorescent AGEs, dityrosine, kynurenine, N'-formylkynurenine, 3-deoxyglucosone, glyoxal, and methylglyoxal by 80%, 97%, 56%, 86%, 46%, 54% and 62%, respectively...

Enzymatic hydrolysis of fish proteins has been employed as a principle method for converting under-utilised fish into valuable products for the pharmaceutical and health food industries. In this study, six commercial enzymes were tested for their ability to make fish protein hydrolysate powders from whole blue whiting. The chemical and functional properties of these powders were compared. The powders all had high solubility (>80%) across a wide pH range in water and their solubility improved further within a vitamin-tea beverage matrix (>85%)...

Anthocyanins are potential food colorants due to their color, low toxicity and biological properties. However, the low chemical stability of anthocyanins has limited their use. In this work, the thermal stability of cyanidin-3-O-glucoside (cy3glc) (major blackberry anthocyanin) and blackberry purees through molecular inclusion with β-cyclodextrin (β-CD) was assessed. Complexation with β-CD showed a thermal stabilization of cy3glc, resulting on a decrease of the degradation rate constant (k) and in several alterations in the cy3glc-β-CD DSC thermogram...
