Gene-environment interactions of CETP gene variation in a high cardiovascular risk Mediterranean population
2010
Genome-wide association studies show that cholesteryl ester transfer protein (CETP) single nucleotide polymorphisms (SNPs) are more strongly associated with HDL cholesterol (HDL-C) concentrations than any other loci across the genome. However, gene-environment interactions for clinical applications are still largely unknown. We studied gene-environment interactions between CETP SNPs and dietary fat intake, adherence to the Mediterranean diet, alcohol consumption, smoking, obesity, and diabetes on HDL-C in 4,210 high cardiovascular risk subjects from a Mediterranean population. We focused on the −4,502C>T and the TaqIB SNPs in partial linkage disequilibrium (D'= 0.88; P < 0.001). They were i…
The rs1466113 Polymorphism in the Somatostatin Receptor 2 Gene Is Associated with Obesity and Food Intake in a Mediterranean Population
2009
<i>Background:</i> A genome-wide association study identified rs1466113 (G>C) in the somatostatin receptor 2 (SSTR2) gene as one of the polymorphisms most significantly associated with body mass index (BMI). As replication is required, we examined the association between this polymorphism and anthropometric variables and food intake in a Mediterranean population. <i>Methods:</i> We studied 945 high cardiovascular-risk subjects (340 men and 605 women) aged 67 ± 6 years, participating in the PREDIMED-Valencia Study. Demographic, clinical, biochemical, dietary, genetic and anthropometric data were obtained. <i>Results:</i> We found recessive effects for t…
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…
Nutrigenetics, nutrigenomics and phenotypic outcomes of dietary low-dose alcohol consumption in the suppression and induction of cancer development: …
2020
It is known that the intake of alcoholic beverages may impair genetic and epigenetic regulatory events with consequent crucial effects on cell phenotypes and that its association with selected genotypes can lead to a different risk of cancer in the population. The aim of this review is to pick up selected studies on this topic and recapitulate some of the biochemical and nutrigenetic/nutrigenomic aspects involved in the impact of dietary low-dose alcohol consumption on the switching-on or -off of tumorigenic pathways. These include i) the existence of predisposing or protective human genotypes and the relationship between dietary compounds and alcohol in the promotion or inhibition of carci…
Utilizing nutritional genomics to tailor diets for the prevention of cardiovascular disease: a guide for upcoming studies and implementations.
2017
Introduction: Personalized diets based on an individual’s genome to optimize the success of dietary intervention and reduce genetic cardiovascular disease (CVD) risk, is one of the challenges most frequently discussed in the scientific community. Areas covered: The authors gathered literature-based evidence on nutritional genomics and CVD phenotypes, our own results and research experience to provide a critical overview of the current situation of using nutritional genomics to tailor diets for CVD prevention and to propose guidelines for future studies and implementations. Expert commentary: Hundreds of studies on gene-diet interactions determining CVD intermediate (plasma lipids, hypertens…
Nutrition in the genomics era: cardiovascular disease risk and the Mediterranean diet.
2007
The effect of dietary changes on phenotypes (i.e., plasma lipid measures, body weight and blood pressure) differs significantly between individuals. This phenomenon has been more extensively researched in relation to changes in dietary fat and plasma lipid concentrations for the prevention of cardiovascular disease (CVD) compared to other pathological conditions. Although common knowledge associates low fat diets with reductions in total and plasma LDL cholesterol, the clinical evidence shows dramatic inter-individual differences in response that are partially due to genetic factors. The discovery of the cardioprotective and other healthy properties of the Mediterranean diet has popularized…
Innovations in Infant Feeding: Future Challenges and Opportunities in Obesity and Cardiometabolic Disease
2020
The field of nutrition in early life, as an effective tool to prevent and treat chronic diseases, has attracted a large amount of interest over recent years. The vital roles of food products and nutrients on the body’s molecular mechanisms have been demonstrated. The knowledge of the mechanisms and the possibility of controlling them via what we eat has opened up the field of precision nutrition, which aims to set dietary strategies in order to improve health with the greatest effectiveness. However, this objective is achieved only if the genetic profile of individuals and their living conditions are also considered. The relevance of this topic is strengthened considering the importance of …
