Abstract
The influence of maternal fat mass and obesity (FTO) gene polymorphism on neonatal insulin sensitivity/resistance biomarkers and lipoprotein profile has not been tested. The study aimed to assess the association between the FTO rs9939609 polymorphism in mother-neonate couples and neonatal anthropometrical measurements, insulin sensitivity/resistance, and lipid and lipoprotein concentrations at birth. Fifty-three term, appropriate-for-gestational-age, Caucasian newborns together with their respective mothers participated in a cross-sectional study. Sixty-six percent of mothers and neonates carried the A allele (being AA or AT). TT mothers gained less weight during pregnancy, but non-significant maternal gene influence was found for neonatal bodyweight, body mass index, or ponderal index. Neonates from AA + AT mothers showed lower glucose, insulin, and homeostatic model assessment insulin resistance (HOMA-IR) but higher homeostatic model assessment insulin sensitivity (HOMA-IS) and homocysteine than neonates whose mothers were TT. AA + AT neonates had higher insulin and HOMA-IR than TT. The genotype neonatal × maternal association was tested in the following four groups of neonates: TT neonates × TT mothers (nTT × mTT), TT neonates × AA + AT mothers (nTT × mAA + AT), AA + AT neonates × TT mothers (nAA + AT × mTT), and AA + AT neonates × AA + AT mothers (nAA + AT × mAA + AT). Non-significant interactions between neonatal and maternal alleles were found for any parameter tested. However, maternal alleles affected significantly glucose, insulin, HOMA-IR, and homocysteine while neonatal alleles the arylesterase activity. Most significant differences were found between nATT + AA × mTT and nATT + AA × mAA + AT. Glycemia, insulinemia, and HOMA-IR were lower, while the Mediterranean diet adherence (MDA) was higher in the mAA + AT vs. mTT whose children were AA + AT. This dietary fact seems to counterbalance the potential negative effect on glucose homeostasis of the obesogenic A allele in neonates.

Abstract
Type 2 diabetes is a very prevalent chronic disease. Among dietary factors for its prevention and treatment, interest has grown in satiating fibre (konjac glucomannan) and spirulina. Our previous studies suggest that glucomannan itself and/or in conjunction to spirulina displayed hypolipemic and antioxidant effects when incorporated to squid surimi as functional ingredients. The present study aims to determine whether glucomannan- enriched or glucomannan plus spirulina-enriched squid-surimi improve plasma glucose and insulin levels in Zucker fa/fa rats fed a high saturated fat diet. Twenty four growing rats, divided into three groups, were given modified AIN-93M diets for seven weeks: 30% squid-surimi control diet (C), 30% glucomannan-enriched squid-surimi diet (G) and 30% glucomannan plus spirulina-enriched squid-surimi diet (GS). All rats became hyperglycemics and hyperinsulinemics, but G and GS diets induced significantly lower glucose levels (20%; p < 0.05) but did not modify insulinemia with respect to C diet. GS animals showed higher HOMA-D (p < 0.05) than C ones suggesting increased insulin availability. Plasma leptin and adiponectin decreased in G and GS vs. C group (p < 0.05). Adipose adiponectin increased significantly in G and GS vs. C rats (16-20 times, p < 0.01). Leptin in adipose tissue was higher in GS vs. G group (p < 0.05). In conclusion, both glucomannan-diets were able to reduce hyperglycemia and increase adipose tissue adiponectin levels in fa/fa rats, suggesting an anti-hypertrophic and insulin-sensitizing adipokine effect in this tissue. Spirulina inclusion increased insulin availability. Although results are promising, the utility of consuming glucomannan surimis as part of usual diets demands future studies.

Abstract
BACKGROUND Research has shown that silicon can play an important role in protecting against degenerative diseases. Restructuring pork by partially disassembling meat permits the incorporation of active components with potential functional effects. However, there has been no research to date on the impact that silicon, as a functional ingredient in restructured pork (RP), has on lipoprotein composition, metabolism, and oxidation. OBJECTIVE This study was designed to evaluate the effect of silicon-enriched RP on lipemia, lipoprotein profile, and oxidation markers of aged rats fed high-fat, high-energy, cholesterol-enriched diets. METHODS RP samples similar to commercial sausages (16% protein and 22% fat, wt:wt) were prepared by mixing lean pork and lard alone or with silicon (1.3 g Si/kg fresh matter) under controlled conditions and then freeze-dried. Saturated fat-rich diets were designed by mixing 78.3% purified diet with 21.7% freeze-dried RP. Three groups composed of 8 aged male Wistar rats (1 y old) were fed for 8 wk a control RP (C) diet, a cholesterol-enriched RP (Chol-C) diet [C diet enriched with 1.26% cholesterol plus 0.25% cholic acid, or a cholesterol and silicon-enriched RP (Chol-Si) diet (same as the Chol-C diet but containing silicon)]. Plasma lipid concentrations, lipoprotein profile, the degree of VLDL oxidation, and LDL receptor gene (Ldlr) expression were tested. RESULTS Compared with the C diet, the Chol-C diet did not modify food intake or body weight but significantly increased (P < 0.05) plasma cholesterol (32%) and total lipids (19%), VLDL and intermediate density lipoprotein + LDL cholesterol (both >600%), total lipids and proteins (both >300%), and the degree of VLDL oxidation [conjugated dienes >250%; thiobarbituric acid-reactive substance (TBARS), 900%] and reduced Ldlr expression (64%) and liver arylesterase activity (54%). The Chol-Si diet partially normalized changes induced by the Chol-C diet. Compared with the Chol-C group, Chol-Si rats had lower VLDL compound concentrations (P < 0.001; e.g., 75% less VLDL cholesterol) and VLDL oxidation (65% less conjugated dienes and 85% less TBARS) but greater Ldlr expression (200%). CONCLUSIONS Silicon added to RP strongly counterbalanced the negative effect of high-cholesterol-ingestion, functioning as an active hypocholesterolemic, hypolipemic, and antioxidative dietary ingredient in aged rats.

Abstract
INTRODUCTION meat products have been recognized to be adequate matrix for incorporating functional ingredients. The impact of meat products formulated by replacing animal fat with a combination of olive, linseed and fish oils on energy and nutrient intakes and anthropometric measurements were tested in a non-randomized-controlled- sequential study. METHODS eighteen male volunteers at high-CVD risk consumed weekly 200 g frankfurters and 250 g pâtés during three 4-wk periods (reduced fat (RF); n3-enriched- RF (n-3RF), and normal fat (NF)), separated by 4-wk washout. Energy and nutrient intakes, healthy eating index (HEI), and anthropometric changes were evaluated. RESULTS body fat mass rate-of-change and the waist/ hip ratio significantly differs (p = 0.018 and p = 0.031, respectively) between periods, decreasing body fat mass, waist circumference and waist/hip ratio in RF period and increasing body fat mass in NF one (all p = 0.05). Significant inverse correlations were observed between rate- of-change of BMI and ideal body weight with dietary carbohydrate/SFA ratio in n-3RF period (p = 0.003 and p = 0.006, respectively). Initial diets presented low HEIs (means < 60). Carbohydrate, fat and protein energy contribution was 40%, 41%, and 16%, respectively. More than 33% of volunteers did not initially cover 70% of several minerals and vitamins RDAs. Product consumption improved dietary Zn, Ca, retinol equivalent, folate and vitamin B12 contents in all periods, and ameliorated n-3 PUFA contents and n-6/n-3 PUFA ratio over the n-3RF period. CONCLUSION improved-fat meat products appear as functional foods for overweight/obeses since their consumption improved selected body-fat markers, without affecting HEI, macronutrient and energy but their n-3 PUFA and n6/n3 ratio intakes.

Abstract
Ripening modifies oil attributes and composition. However, the influence of olive ripening on virgin olive oil (VOO) thermal oxidative stability on food-frying has not been studied yet. Oils from Picual olives of low (VOO1), medium (VOO2), and high (VOO3) ripeness were obtained, and their thermal oxidative stability during 40 potato-fryings was tested. Unused VOO1 showed higher antioxidant content and oxidative stability than VOO2 and VOO3. Polar compounds (PC), oligomers, and altered fatty acid methyl esters (polar-FAME) increased, whereas linoleic acid, polyphenols, and tocopherols decreased in the three VOOs through frying. The alteration was lower in VOO1, followed by VOO2 (0.105, 0.117, and 0.042 g/100 g oil less of PC, oligomers and polar-FAME per frying, respectively, in VOO1 than in VOO3). In conclusion, VOO obtained from low-ripeness Picual olives should be preferred when frying fresh-potatoes due to its higher thermal and oxidative stability, permitting a higher number of potato-frying uses.

Abstract
BACKGROUND Mediterranean diet consumption is associated to low prevalence of major degenerative diseases. Low Mediterranean-diet-adherence (MDA) score has been related to high insulin and homeostatic model assessment-insulin resistance levels at birth. The relationship between maternal MDA and offspring lipoprotein profile at birth has been scarcely reported. METHODS Cross-sectional study aimed to study the relationship between pregnancy diet quality and serum lipid, arylesterase and homocysteine values at birth. Cord blood of the offspring of 35 women whose diets were classified as "adequate" or "inadequate" according to their 13-point MDA-score (≥7 or <7, respectively) were studied. RESULTS MDA-scores did not significantly change through pregnancy. Low-MDA-score diets presented a higher atherogenic index, contained less fiber and folates, and had a lower (polyunsaturated + monounsaturated)/saturated fatty acids (PUFA + MUFA/SFA) ratio, more cholesterol, and higher SFA/carbohydrates (SFA/CHO) and ω-6/ω-3 PUFA ratios than their respective high-MDA-score counterparts. Mothers at the low MDA-score delivered neonates with high LDL-c (P = 0.049), Apo B (P = 0.040), homocysteine (P = 0.026) and Apo A1/Apo B ratio (P = 0.024). CONCLUSIONS Neonates whose mothers consumed low MDA diets presented impaired lipoprotein and increased homocysteine levels at birth. A follow-up study on early cardiovascular disease prevention is needed to understand the importance of present findings later in life.

Abstract
Background Hydrogen peroxide (H2O2) is a toxic agent that induces oxidative stress and cell death. Silicon (Si) is a biological element involved in limiting aluminium (Al) absorption with possible preventive effects in Alzheimer’s disease. However, Si has not yet been associated with other neuroprotective mechanisms. Methods The present experiments evaluated in the SH-SY5Y human neuroblastoma cell line the possible role of different Si G5 (50-1000 ng/mL) concentrations in preventing cellular death induced by H2O2 (400 μM, 24 hours). Results Our findings showed that H2O2 promoted cell death in the human SH-SY5Y cell cultures and this could be prevented by Si treatment. The loss in cell viability mediated by H2O2 was due to an apoptotic and necrotic process. Apoptotic death was incurred by regulating caspase-8 activity in the extrinsic pathway. The apoptotic and necrotic cell death induced by H2O2 was almost totally reversed by Si (50-500 ng/mL), indicating that it down-regulates both processes in H2O2 treated cells. Conclusions According to our data, Si is able to increase SH-SY5Y cell survival throughout partially blocking cellular damage related to oxidative stress through a mechanism that would affect H2O2/ROS elimination.

Abstract
INTRODUCTION Abdominal fat mass is an important risk factor of inflammation in the general population as it is in haemodialysis (HD) patients. The aim of this study was to investigate the association of adiposity using the conicity index (Ci) with nutritional-inflammatory markers and to analyse whether these factors were related with the clinical outcome in HD patients. METHODS A cross-sectional study in 80 HD patients (men, 65%; aged 68.2 ± 14.2) was carried out. Abdominal fat deposition was evaluated by Ci median with regard to baseline inflammatory, anthropomorphic, and nutritional markers. Linear regression analysis was applied to identify whether serum C-reactive protein (CRP), as an inflammatory biomarker, was an independent predictor of Ci in HD patients. RESULTS Mean Ci was significantly greater in men (p = 0.001). Significant positive correlations were observed between Ci and serum triglycerides (r = 0.23; p < 0.05) and Ln of serum CRP (r = 0.27; p < 0.01). A significantly higher median Ci (men ≥ 1.39 and women ≥ 1.33) was observed in inflammated overweight patients by multivariate analysis (p < 0.05). Serum CRP, as an inflammatory biomarker, was a significant predictor (p = 0.021) of Ci, but its predictive value disappeared after median Ci adjustment of linear regression analysis. CONCLUSION Abdominal fat mass, measured by Ci, appears directly linked to inflammation in dialysis. Results support the hypothesis that inflammation in HD patients has pleiotropic effects depending on abdominal body adiposity.

Abstract
There is a general assumption that seaweeds are hypocholesterolemics and antioxidants. However, controversial results suggest specific properties for each individual alga. This study aims to assess the effect of including Sea Spaghetti alga (S) in a restructured-pork (RP) diet, both enriched and not enriched with dietary cholesterol, on arylesterase (AE) activity and lipoprotein concentration and composition of Wistar rats. Four groups of 10 growing male Wistar rats were each fed a mix of 85% AIN-93M diet and 15% freeze-dried RP for 5 weeks. The control group (C) consumed control RP-C; the S group consumed RP-S with 5% seaweeds; the Chol-C group consumed the C diet but enriched with cholesterol (2.43%) and cholic acid (0.49%); the Chol-S group consumed the S diet but enriched with cholesterol and cholic acid. AE activity was five times higher (P<.01) in S compared with C rats, but three times lower in Chol-S compared with Chol-C rats (P<.01). The Chol-C diet induced hypercholesterolemia but reduced triglycerides (TG), giving rise to the presence of very low-density lipoprotein (VLDL) that was enriched in cholesterol. The Chol-S diet partially blocked (P<.001) the hypercholesterolemic induction of the Chol-C diet, and reduced TG levels (P<.05) with respect to S rats. The cholesterol supplementation increased total cholesterol, VLDL-cholesterol, and intermediate-density lipoprotein+LDL-cholesterol (IDL+LDL)-cholesterol (P<.001) in Chol-C rats, but the effect was lower in the Chol-S diet. In conclusion, RP-S increases the antioxidant capacity within a noncholesterol enriched diet while improving the lipoprotein profile within a cholesterol-enriched diet.

Abstract
BACKGROUND Seaweeds are good sources of dietary fibre, which can influence glucose uptake and glycemic control. OBJECTIVE To investigate and compare the in vitro inhibitory activity of different extracts from Undaria pinnatifida (Wakame), Himanthalia elongata (Sea spaghetti) and Porphyra umbilicalis (Nori) on α-glucosidase activity and glucose diffusion. METHODS The in vitro effects Chloroform-, ethanol- and water-soluble extracts of the three algae were assayed on α- glucosidase activity and glucose diffusion through membrane. Principal Components Analysis (PCA) was applied to identify patterns in the data and to discriminate which extract will show the most proper effect. RESULTS Only water extracts of Sea spaghetti possessed significant in vitro inhibitory effects on α-glucosidase activity (26.2% less mmol/L glucose production than control, p < 0.05) at 75 min. PCA distinguished Sea spaghetti effects, supporting that soluble fibre and polyphenols were involved. After 6 h, Ethanol-Sea spaghetti and water-Wakame extracts exerted the highest inhibitory effects on glucose diffusion (65.0% and 60.2% vs control, respectively). This extracts displayed the lowest slopes for glucose diffusion-time lineal adjustments (68.2% and 62.8% vs control, respectively). CONCLUSIONS The seaweed hypoglycemic effects appear multi-faceted and not necessarily concatenated. According to present results, ethanol and water extracts of Sea spaghetti, and water extracts of Wakame could be useful for the development of functional foods with specific hypoglycemic properties.

Abstract
The arylesterase (ARE) activity linked to the paraoxonase-1 (PON1) gene is known to protect lipoproteins from oxidation and provide defense against metabolic syndrome (MetS) and cardiovascular diseases. The epigenetic regulation of enzymatic activities is gaining importance nowadays. This research aimed to assess the potential relationships between the ARE activity with the methylation levels of the PON1 gene transcriptional regulatory region, anthropometrics, biochemical markers and antioxidant dietary components. Forty-seven subjects (47 ± 10 y.o; BMI 36.2 ± 3.8 kg/m(2); 46.8 % female) with MetS features, who followed a six-month energy-restricted dietary weight-loss intervention, were included in this study (www.clinicaltrials.gov; NCT01087086). Anthropometric, biochemical, enzymatic and dietary data were assessed using validated procedures. PON1 transcriptional regulatory region methylation was analyzed by a microarray technical approach. Volunteers reduced ARE activity in parallel with body weight (p = 0.005), BMI (p = 0.006), total fat mass (p = 0.020), diastolic blood pressure (p = 0.018), mean blood pressure (p = 0.022) and triglycerides (p = 0.014). Methylation levels of some CpG sites of the PON1 gene correlated negatively with ARE activity (p < 0.05). Interestingly, dietary vitamin C (p = 0.001), tocopherols (p = 0.009) and lycopene (p = 0.038) were positively associated with ARE activity and showed an inverse correlation (p = 0.004, p = 0.029 and p = 0.021, respectively) with the methylation of some selected CpG sites of the PON1 gene. In conclusion, ARE activity decreased in parallel with MetS-related markers associated to the energy restriction, while dietary antioxidants might enhance the ARE activity by lowering the PON1 gene methylation in patients with MetS features.

Abstract
INTRODUCTION Malnutrition/wasting/cachexia are complex-disease conditions that frequently remain undiagnosed and/or untreated in up to 75% of prevalent hemodialysis (HD) patients. The nutrition care process (NCP) based on assessment, diagnosis, intervention and monitoring of nutritional status is a systematic method that nutrition professionals use to make decisions in clinical practice. OBJECTIVE This review examines from a clinical-nutritional practice point of view: a) nutritional status as a mortality causative factor; b) phenotypic characteristics of malnutrition/wasting/cachexia, and c) current trends of NCP with special emphasis on nutritional support and novel nutrient and pharmacologic adjunctive therapies in HD patients. METHOD A literature review was conducted using the Pubmed, Science Direct, Scielo, Scopus, and Medline electronic scientific basis. Studies which assessing nutritional status and nutritional support published from 1990 to 2013 in HD patients were included and discussed. RESULTS From all the epidemiological data analyzed, NCP was the suggested method for identifying malnutrition/ wasting or cachexia in clinical practice. Nutrition support as an unimodal therapy was not completely able to reverse wasting in HD patients. Novel experimental therapeutic strategies including the use of appetite stimulants, ghrelin agonist, MC4-R antagonists, anabolic steroids, anti-inflammatory drugs, cholecalciferol, and other components are still under clinical evaluation. CONCLUSION Nutritional status is a strong predictor of morbidity and mortality in HD patients. The terms called malnutrition, wasting and cachexia have different nutritional therapeutics implications. The NCP is a necessary tool for assessing and monitoring nutritional status in the current clinical practice. Novel pharmacological therapies or specific nutrient supplementation interventions studies are required.

Abstract
Pregnancy is a vital period where several hyperplasic, hypertrophic processes together with metabolic adaptation and preparation for extra-uterine life take place. Present review accounts for central aspects of nutrition throughout gestation on the embryonic and fetal periods. It is centered in the major changes occurring in fetal pancreas, with special mention to the susceptibility of this main glucose homeostasis organ to support nutritional changes during maturation and development. Studies performed in animal models as human are commented considering the role of maternal nutrition on β-cell mass size, insulin and other pancreatic hormones production, and insulin sensitivity. Details of both the thrifty genotype and phenotype hypothesis are given, indicating that hypo/subnutrition causes metabolic adaptations that permit the future body to grow and develop itself in limited environmental and energetic conditions. The Barker hypothesis is considered suggesting that this metabolic hypothesis is a double-edged sword in the actual abundance World. Lastly the review, taking into account our own research and other papers, analyses less known aspects that relate maternal diet with insulin resistance/sensitivity markers at delivery. Particularly the role of the saturated fatty acid/carbohydrate and omega-6/omega-3 ratios in the frame of maternal diet is reviewed considering the quality of those diets under the Healthy Eating Index and the Adherence to Mediterranean Diet scores and the relationship with insulin resistance profile at birth. Present review ends indicating that nutritional habits should be strongly stated before gestation in order to assure a proper nutrition since the first moment of pregnancy. This will support an adequate fetal and pancreatic growth and development, and in turn, adequate glucose homeostasis during pregnancy and later in life, slowing down or preventing from degenerative diseases related with metabolic syndrome and type 2 diabetes mellitus.

Abstract
The effect of high-fat squid-surimi diets enriched in glucomannan or glucomannan-spirulina on lipemia, liver glutathione status, antioxidant enzymes and inflammation biomarkers was determined in Zucker Fa/Fa rats. Groups of eight rats each received for 7weeks the squid-surimi control (C), glucomannan-enriched squid-surimi (G) and glucomannan-spirulina enriched squid-surimi (GS). Liver weight, cytochrome P450 7A1 expression and cholesterolemia were decreased in G and GS vs. C, improving glutathione red-ox index (p<0.05). G also showed increased glutathione reductase (GR) levels vs. C, but reduced the endothelial (eNOS) and increased the inducible nitric oxide synthase (iNOS) and tumor necrosis factor-alpha (TNF-α) levels (p<0.05). The GS diet improved superoxide dismutase, catalase, glutathione peroxidase and GR activities and eNOS, iNOS and TNF-α levels (p<0.05). The glucomannan enriched surimi-diet induced hypocholesterolemic, antioxidant and proinflammatory effects, while the addition of 3g/kg spirulina kept those hypocholesterolemic and antioxidant effects but reduced the inflammation observed.

Abstract
BACKGROUND The relationship between serum minerals and homocysteine, lipoprotein and glucose homeostasis markers at birth has been scarcely reported. This study aims to determine a) the relationship between calcium, magnesium, cardiovascular disease (CVD) markers (e.g. lipids, lipoproteins, homocysteine) and insulin sensitivity/ resistance markers (e.g. glucose, insulin, HOMA) in cord serum; and b) to find out the possible influence of reduced or increased levels of serum calcium and magnesium on those markers. SUBJECTS AND METHODS Forty-eight eutocic, normoweight and appropriated-for-gestational age, full-term, singleton without foetal distress newborns from the Mérida Study were studied. Parameter percentiles for serum calcium and magnesium as well as for the Ca/Mg ratio were stated. CVD and insulin sensitivity/resistance markers in neonates within the first quartile for calcium, magnesium and their ratio were compared with those of neonates within the forth quartile for these minerals. RESULTS Serum calcium negative correlated with HDL-c (p<0.05), arylesterase (AE) (p<0.01), the Apo A1/Apo B (p<0.05) and AE/HDL-c (p<0.05) ratios. Also, negative and significant correlations were found between the Ca/Mg ratio and AE (p<0.01), and AE/HDL-c (p<0.05). Neonates within the highest quartile for Mg displayed significantly higher levels of LDL-c and homocysteine (p<0.05). Newborns within the Ca/Mg ratio first quartile presented higher activities of AE while those of with high Ca/Mg ratio showed low levels of insulin. CONCLUSIONS Calcium and magnesium levels appear related to CVD and insulin sensitivity/resistance markers at birth. Future follow-up studies, mostly in neonates, with high magnesemia and/or high Ca/Mg ratio at birth are recommended.

Abstract
Restructured pork (RP) enriched in Seaweeds are potential functional foods. The antiapoptotic and hypocholesterolemic effects of consuming cholesterol enriched diets containing Wakame-RP (CW), Nori-RP (CN) and Sea Spaghetti (CS) were tested in a 1-wk study. Groups of six rats per group were fed a mix of 85% AIN-93M rodent-diet containing cholesterol and cholic acid as a cholesterol rising agent plus 15% RP containing alga. These diets were compared to control-RP diets enriched or not in cholesterol (CC and C, respectively). After 1-wk, cholesterol feeding significantly increased liver apoptosis markers which were significantly reduced by CS (cellular cycle DNA, caspase-3, and cytochrome c), CN (caspase-3 and cytochrome c) and CW (caspase-3) diets. CN and CS diets significantly blocked the cholesterolaemic rising effect observed in the CC group but no protective effect was observed in the CW group. Differences in seaweed composition added to RP appear responsible for blocking or not the proapoptotic and hypercholesterolemic effects of high cholesterol-RP consumption; thus, any generalization on seaweed effects or food containing seaweeds must be avoided. Although present results are worthy, future studies are demanded to ascertain the utility of consuming algal-RP as part of usual diets.

Abstract
Early alterations in glucose homeostasis increase the risk of developing insulin resistance and obesity later in life. The concurrence of altered lipids and insulin sensitivity/resistance markers at birth has been scarcely investigated. The study aimed to ascertain level ranges of homocysteine (tHcyt), arylesterase (AE), lipids/lipoproteins, and insulin resistance/sensitivity markers in full-term neonates and to determine the concurrence effect of dyslipaemia and dysglycaemia on those parameters at birth. Participants were 197 full-term, 2.5 to <4.0 kg, without foetal distress Spanish newborns from the Mérida Study. Parameter percentiles for males and females were stated. The effect of the concurrence high glucose/high triglycerides (high glucose/high TG) or high glucose/low cholesterol transported by HDL (HDL-c) on tHcyt, LDL-c, HDL-c, lipoprotein (a) (Lp(a)), oxidised LDL (oxLDL), AE, glucose, insulin sensitivity (QUICKI) and insulin resistance index (HOMA-IR) was studied. Females had higher total cholesterol (TC), HDL-c, Apo A1, Lp(a) and HDL-c/Apo A1, but lower relative transport of TC (%TC) by the very low lipoprotein fraction than males. No gender differences were found for glucose, HOMA-IR and QUICKI. Neonates at the 2.5- to 2.999-kg range display more adequate HOMA-IR and QUICKI levels that their >3.0 kg counterparts. The concurrence of high glucose/high TG or high glucose/low HDL-c increased TC/HDL-c and HOMA-IR, but decreased, oxLDL, oxLDL/LDL-c and QUICKI with respect to that of low glucose/low TG or glucose/high HDL-c. The concurrence glucose/TG has predictive value for low QUICKI, whilst that of glucose/HDL-c for low QUICKI and high HOMA-IR, suggesting the importance of routine TG, HDL-c and glucose screening at birth as it would identify candidates for insulin resistance.

Abstract
Seaweed enriched-restructured pork (RP) is a potential functional food. However, indications of adverse effects associated with herbal medications, which include among others liver failure, toxic hepatitis, and death have been reported. Cholesterol feeding produces hepatomegalia and fat liver infiltration. The effect of seaweed-RP diet, cholesterol-enriched or not, on plasma cholesterol, liver damage markers, structure, and cytochrome CYP4A-1 were evaluated after 5 wk. Eight rat groups were fed a mix of 85% AIN-93M rodent-diet plus 15% RP. The Cholesterol-control (CC), Cholesterol-Wakame (CW), Cholesterol-Nori (CN) and Cholesterol-Sea Spaghetti (CS) groups respectively consumed similar diets to control (C), Wakame (W), Nori (N), and Sea Spaghetti (S) but as part of hypercholesterolaemic diets. CN and CS significantly blocked the hypercholesterolaemic effect observed in CC group. After 5-wk, N and S diets increased the CYP4A-1 expression. However, seaweed-RPs were unable to reduce the histological liver alterations observed in CC group. Larger and more abundant hepatocellular alterations were found in CS and CN rats suggesting that the hypocholesterolaemic effects of these seaweed-RPs seem to be a two-edged sword as they increased liver damage. Future studies are needed to understand the involved mechanisms.

Abstract
This review deals with the two major aspects to be considered in the context of meat-based functional foods and human health. One involves the different strategies used to improve (increase or reduce) the presence of bioactive (healthy and unhealthy) compounds in meat and meat products in order to develop potential meat-based functional foods; these strategies are basically concerned with animal production practices, meat processing and storage, distribution and consumption conditions. Since the link between the consumption of those foods and their potentially beneficial effects (improving health and/or reducing the risk of several chronic diseases) needs to be demonstrated scientifically, the second aspect considered is related to intervention studies to examine the functional capacity of meat-based potentially functional foods in humans, discussing how the functionality of a food can be assessed in terms of its effects on health in relation to both target body functions and risk factors.

Abstract
BACKGROUND Inclusion of seaweeds in restructured pork (RP) would improve meat health properties. AIM The aim was to determine the effects of RP containing Himanthalia elongata on growth, organ weight, cholesterolemia, and expression of lipoprotein lipase (LPL), acetyl CoA carboxylase (ACC), fatty acid synthase (FAS), and hormone-sensitive lipase (HSL) in adipose tissue of Wistar rats. METHODS The control group (C) consumed control RP, and the seaweed group (SS) consumed RP with 5% Himanthalia elongata. Animals on cholesterol-enriched diets (CholC, CholSS) consumed their corresponding basal diets with supplementary cholesterol (2.43%) plus cholic acid (0.49%) as hypercholesterolemic agents. RESULTS Seaweed inclusion did not modify cholesterolemia but reduced (p < 0.01) the hypercholesterolemic effect of dietary cholesterol plus cholic acid. CholC rats presented lower (p < 0.05) adipose fat and weight than C rats. Cholesterol feeding affected HSL, ACC, and FAS expression (p < 0.05), while alga consumption influenced HSL and ACC (p < 0.05). LPL was not significantly affected by both factors. CholSS rats showed decreased HSL and FAS (p < 0.05) but increased ACC (p < 0.05) expression compared with CholC rats. CONCLUSION Himanthalia RP partially blocked the dietary hypercholesterolemic effect and changed the lipogenic/lipolytic enzyme expression, reducing the wasting effect of hypercholesterolemia on adipose tissue in rats.

Abstract
Cardiovascular disease (CVD) is the leading cause of mortality and morbidity in developed countries. CVD is an inflammatory disease associated with risk factors that include hypercholesterolemia and hypertension. Furthermore, the evolution of this disease depends on the amount of modified lipoproteins (e.g. oxidized) present in the arterial subendothelium. Diet is considered the cornerstone for CVD treatment, as it can lower not only atherogenic lipoprotein levels and degree of oxidation, but also blood pressure, thrombogenesis and concentrations of some relevant factors (e.g. homocystein).Among different diets, the Mediterranean diet stands out due to their benefits on several health benefits, in particular with regard to CVD. Rich in vegetable foods, this diet contributes both quantitatively and qualitatively to essential fibre compounds (cellulose, hemicellulose, gums, mucilages, pectins, oligosaccharides, lignins, etc.). The present paper analyzes the effects of fibre consumption on a) cholesterol and lipoprotein levels; b) systolic and diastolic blood pressures; and c) antioxidant availability and profile. Some studies and meta-analysis are revised, as the possible mechanisms by which fibre may decrease plasma total cholesterol and LDL-cholesterol and blood pressure and to act as antioxidant, as well. In addition, author's own publications regarding the effect of fibre matrix (e.g. seaweeds) on arylesterase and the gene expression of some key antioxidant enzymes are reviewed. The paper also includes data concerning the possible interaction between fibre and some hypolipemic drugs, which may make it possible to attain similar hypolipemic effects with lower dosages, with the consequent decrease in possible side effects. The review concludes with a summary of nutritional objectives related to the consumption of carbohydrates and fibre supplements.

Abstract
OBJECTIVE This study aims to ascertain the relationships between mineral consumption, hair mineral content, and blood pressure. METHODS The study involved 26 postmenopausal women from enclosed religious communities, 14 were semi-vegetarians and 12 were omnivores. Mineral dietary assessment was performed using a 14-d precise weight method and Food tables. Hair mineral levels were measured by means Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-OES). Multivariable stepwise linear regression analyses were performed to find out the variables that affected most blood pressure. RESULTS In general terms, the omnivorous diet contained a significantly higher mineral content than the semi-vegetarian one. The mineral intake from both diets implied no health risk to the women studied, as their estimated daily intake (EDI) of toxic elements such as Cd and Pb was lower than their respective provisional tolerable weekly intake (PTWI) of these minerals. Hair of the semi-vegetarians contained higher amounts of Al (p < 0.01), Ba (p < 0.01), K (p < 0.001), Na (p < 0.001), Pb (p < 0.001) and Mn (p < 0.01) but lower levels of Ca (p < 0.05) and Zn (p < 0.05) than that of their omnivorous counterparts. The omnivores presented significantly higher systolic (p < 0.01) and diastolic (p < 0.05) pressures than the semi-vegetarians. Levels of hair Co (R² = 0.328; p = 0.032) and hair K (R² = 0.409; p = 0.014)) were explicative for systolic and diastolic blood pressure, respectively. CONCLUSION Several dietary mineral and hair contents were higher in semi-vegetarian women suggesting that the hair is an important mineral excretion via contributing to maintain blood pressure at low levels.
