Genome-Wide Association Study (GWAS) on Bilirubin Concentrations in Subjects with Metabolic Syndrome: Sex-Specific GWAS Analysis and Gene-Diet Intera…

2019

Although, for decades, increased serum bilirubin concentrations were considered a threatening sign of underlying liver disease and had been associated with neonatal jaundice, data from recent years show that bilirubin is a powerful antioxidant and suggest that slightly increased serum bilirubin concentrations are protective against oxidative stress-related diseases, such as cardiovascular diseases. Therefore, a better understanding of the gene-diet interactions in determining serum bilirubin concentrations is needed. None of the previous genome-wide association studies (GWAS) on bilirubin concentrations has been stratified by sex. Therefore, considering the increasing interest in incorporat…

Sex-Specific Differences in the Control of Serum Concentrations of Glycine in Subjects with Metabolic Syndrome and Mendelian Randomization Analysis f…

2020

OBJECTIVES: Glycine is a novel circulating marker for metabolic diseases associated with lower type-2 diabetes and protection against obesity in some studies. Circulating glycine levels are genetically determined under the control of several loci. The locus most strongly associated is the carbamoyl-phosphate synthase I (CPS1). Interestingly, some sex-specific genome-wide association studies (GWAS) showed differences in the effect of the main single nucleotide polymorphisms (SNPs) in this locus on glycine levels (significant sex * CPS1 interactions). However, the potential mechanisms explaining this sex-heterogeneity are unknown. Therefore, our aims were: 1) to analyze whether the sex * CPS1…

Short-Term Effects on Gene-Expression and on DNA-Methylation at the Genome-Wide Level of the Iberian Ham Intake and Compared With Orange Intake: A Cr…

2021

OBJECTIVES: Diet regulates gene expression and methylation profiles by several mechanisms. However, studies analyzing the simultaneous effect of specific foods on gene-expression and DNA methylation at the genome-wide level are very scarce. Therefore our aims were: To study the short-term transcriptomics and epigenomcis effects at the genome-wide level of the Iberian ham intake compared with orange intake in the same subjects. METHODS: We carried out a cross-over randomized trial (registered at ISRCTN17906849) in 33 healhty volunteers (aged 18–50 years and 50% females) of European ancestry. After 12h fasting, participants were randomly allocated to eat 67.5 g of Iberian ham (100% pure iberi…

Abstract MP04: Taste Perception Profiles Are Associated With Patterns Of Adherence To A Mediterranean Diet Among Older Adults With Metabolic Syndrome

2021

Objective: Evidence suggests perception of sweet, salt, sour, bitter, and umami tastes may be independently related to food preferences and intake. Our objective was to determine whether a collective measure of taste perception for all 5 tastes—“taste perception profiles”—was related to adherence to a Mediterranean diet (MedD). Methods: Participants were 367 older adults (55-75 years; 55% female) with metabolic syndrome from PREDIMED-Plus, Valencia. A data-driven clustering approach identified six taste perception profiles from baseline taste perception scores: Low All ( n = 85), High Bitter ( n = 41), High Umami ( n = 61), Low Bitter & Umami ( n = 59), High All But Bitter ( n = 72) an…

MicroRNAs and Drinking : Association between the Pre-miR-27a rs895819 Polymorphism and Alcohol Consumption in a Mediterranean Population

2016

Recently, microRNAs (miRNA) have been proposed as regulators in the different processes involved in alcohol intake, and differences have been found in the miRNA expression profile in alcoholics. However, no study has focused on analyzing polymorphisms in genes encoding miRNAs and daily alcohol consumption at the population level. Our aim was to investigate the association between a functional polymorphism in the pre-miR-27a (rs895819 A>G) gene and alcohol consumption in an elderly population. We undertook a cross-sectional study of PREvención con DIeta MEDiterránea (PREDIMED)-Valencia participants (n = 1007, including men and women aged 67 7 years) and measured their alcohol consumption (to…

Legume consumption is inversely associated with type 2 diabetes incidence in adults: A prospective assessment from the PREDIMED study

2018

Background & aims: Legumes, a low-energy, nutrient-dense and low glycemic index food, have shown beneficial effects on glycemic control and adiposity. As such, legumes are widely recommended in diabetic diets, even though there is little evidence that their consumption protects against type 2 diabetes. Therefore the aim of the present study was to examine the associations between consumption of total legumes and specific subtypes, and type 2 diabetes risk. We also investigated the effect of theoretically substituting legumes for other protein- or carbohydrate-rich foods. Methods: Prospective assessment of 3349 participants in the PREvención con DIeta MEDiterránea (PREDIMED) study without ty…

Data-Driven Clustering Approach to Derive Taste Perception Profiles from Sweet, Salt, Sour, Bitter, and Umami Perception Scores: An Illustration amon…

2021

BACKGROUND Current approaches to studying relations between taste perception and diet quality typically consider each taste-sweet, salt, sour, bitter, umami-separately or aggregately, as total taste scores. Consistent with studying dietary patterns rather than single foods or total energy, an additional approach may be to study all 5 tastes collectively as "taste perception profiles." OBJECTIVE We developed a data-driven clustering approach to derive taste perception profiles from taste perception scores and examined whether profiles outperformed total taste scores for capturing individual variability in taste perception. METHODS The cohort included 367 community-dwelling adults [55-75 y; 5…

Association of Taste Perception for Sweet, Salt, Sour, Bitter and Umami and Food Intake Among Community-dwelling Adults in the PREDIMED-PLUS Trial (P…

2019

OBJECTIVES: To investigate the association between taste perception for sweet, salt, sour, bitter and umami and food category intakes. We hypothesized that greater taste perception will be inversely associated with the amount consumed. METHODS: A cross-sectional baseline analysis was performed on community-dwelling overweight adults with metabolic syndrome (N = 367, 55–75y) from the PREDIMED-PLUS Trial, University of Valencia Center, Spain. Taste perception was determined by challenging subjects with standard solutions of sweet, salt, sour, bitter and umami (400 mM sucrose, 200 mM NaCl, 34 mM citric acid, 5.6 mM phenylthiocarbamide (PTC), 200 mM monopotassium glutamate, respectively) and ev…

Chronological Age Interacts with the Circadian Melatonin Receptor 1B Gene Variation, Determining Fasting Glucose Concentrations in Mediterranean Popu…

2020

Gene-age interactions have not been systematically investigated on metabolic phenotypes and this modulation will be key for a better understanding of the temporal regulation in nutrigenomics. Taking into account that aging is typically associated with both impairment of the circadian system and a decrease in melatonin secretion, we focused on the melatonin receptor 1B (MTNR1B)-rs10830963 C&gt

Relationship between olive oil consumption and ankle-brachial pressure index in a population at high cardiovascular risk.

Type 2 diabetes and cognitive impairment in an older population with overweight or obesity and metabolic syndrome: baseline cross-sectional analysis …

2018

This study cross-sectionally examines in the elderly population: (a) the association of type 2 diabetes with executive function (EF); (b) the effect of BMI on both type 2 diabetes and EF; (c) the association between glycaemia control and EF in type 2 diabetes. 6823 older individuals with overweight/obesity and metabolic syndrome participating in the PREDIMED-PLUS study, were assessed with a battery of cognitive tests and a medical interview. ANOVA showed a significantly worse performance on EF in type 2 diabetes vs. non-diabetic individuals. Two complementary models were displayed: (1) in the whole sample, the presence of type 2 diabetes, depressive symptoms and BMI had a direct negative ef…

Nutrigenética, nutrigenómica y dieta mediterránea: una nueva visión para la gastronomía

2018

Both nutrigenetics and nutrigenomics are disciplines that form part of what is known as Nutritional Genomics, which, in the widest sense, provides the framework for integrating different omics with food and nutrition sciences. After decades of nutrigenetic and nutrigenomic studies, there is a large enough amount of knowledge to consider its application in so-called precision nutrition. This new discipline seeks to take into account the particular characteristics of the individual in order to provide the best diet for preventing or treating a disease. Omic markers are considered to be of importance to that personalization. There are many foods, nutrients and dietary patterns that have been r…

Association between taste perception and adiposity in overweight or obese older subjects with metabolic syndrome and identification of novel taste-re…

2019

BACKGROUND The relation between taste perception, diet, and adiposity remains controversial. Additionally, there is a lack of knowledge on the polymorphisms influencing taste given the scarcity of genome-wide association studies (GWASs) published. OBJECTIVES We studied the relation between perception of the basic tastes, i.e., sweet, salty, bitter, sour, and umami (separately and jointly in a "taste score"), and anthropometric measurements in older subjects with metabolic syndrome (MetS). GWASs were undertaken to identify genes associated with basic tastes and their score. METHODS Taste perception was cross-sectionally determined by challenging subjects (381 older individuals with MetS) wit…

Influence of Demographic and Lifestyle Variables on Plasma Magnesium Concentrations and Their Associations with Cardiovascular Risk Factors in a Medi…

2020

Several studies have shown that a low magnesium (Mg) intake in the diet is associated with greater cardiovascular risk and greater risk of diabetes. However, the results are not consistent in all populations. To minimize the biases derived from diet measurement, more objective biomarkers of magnesium status have been proposed. Although there is still no ideal biomarker for Mg, several studies have shown that plasma Mg concentrations could be a relatively acceptable biomarker for cardiovascular risk assessment. However, further studies are required to better characterize this marker in different populations. Our aim was to analyze the association between plasma Mg concentrations (measured th…

Dietary fat intake and risk of cardiovascular disease and all-cause mortality in a population at high risk of cardiovascular disease.

2015

Background Dietary fat quality and fat replacement are more important for cardiovascular disease (CVD) prevention than is total dietary fat intake. Objective The aim was to evaluate the association between total fat intake and fat subtypes with the risk of CVD (myocardial infarction, stroke, or death from cardiovascular causes) and cardiovascular and all-cause death. We also examined the hypothetical effect of the isocaloric substitution of one macronutrient for another. Design We prospectively studied 7038 participants at high CVD risk from the PREvencion con DIeta MEDiterranea (PREDIMED) study. The trial was conducted from 2003 to 2010, but the present analysis was based on an expanded fo…

Dietary inflammatory index and all-cause mortality in large cohorts: The SUN and PREDIMED studies

2019

[Background]: Inflammation is known to be related to the leading causes of death including cardiovascular disease, several types of cancer, obesity, type 2 diabetes, depression-suicide and other chronic diseases. In the context of whole dietary patterns, the Dietary Inflammatory Index (DII®) was developed to appraise the inflammatory potential of the diet. [Objective]: We prospectively assessed the association between DII scores and all-cause mortality in two large Spanish cohorts and valuated the consistency of findings across these two cohorts and results published based on other cohorts.

Genome-Wide Association Study for Serum Omega-3 and Omega-6 Polyunsaturated Fatty Acids: Exploratory Analysis of the Sex-Specific Effects and Dietary…

2020

Many early studies presented beneficial effects of polyunsaturated fatty acids (PUFA) on cardiovascular risk factors and disease. However, results from recent meta-analyses indicate that this effect would be very low or nil. One of the factors that may contribute to the inconsistency of the results is that, in most studies, genetic factors have not been taken into consideration. It is known that fatty acid desaturase (FADS) gene cluster in chromosome 11 is a very important determinant of plasma PUFA, and that the prevalence of the single nucleotide polymorphisms (SNPs) varies greatly between populations and may constitute a bias in meta-analyses. Previous genome-wide association studies (GW…

Taste Perception Profiles Are Associated With Adherence to Empirically Derived Dietary Patterns Among Older Adults With Metabolic Syndrome

2021

OBJECTIVES: Understanding individual-level drivers of food intake is critical when personalizing dietary guidance. One likely driver is taste perception; yet, limited data relate perception of all 5 tastes (sweet, salt, sour, bitter, umami) to dietary patterns (DPs). Our aim was to determine whether a multivariable measure of taste perception, taste perception profiles, was associated with adherence to empirically derived DPs. METHODS: Participants were 367 community-dwelling adults with metabolic syndrome from PREDIMED-Plus, Valencia (55–75 years; 55% female). Six taste perception profiles were derived from 5 taste perception scores via a data-driven clustering approach: Low All (23%), Hig…
