DNA methylation of the CYP1A1 and GSTP1 genes and incidence of major cancers (lung, breast and colon) in the PREDIMED-Valencia study

Global and sex-specific epigenome-wide association studies for the identification of the main methylated loci related to smoking in a mediterranean population

Abstract Background Tobacco use has been reported to be the main cause of 90% of male and 80% of female lung cancers, as well as a relevant risk factor for other cancers such as oropharynx, larynx, esophagus, stomach, liver, pancreas, kidney, bladder, and colorectum. Smoking directly affects DNA methylation and although several genes have been reported to be differentially methylated in smokers, gender differences and population-specific differences remain to be further investigated. Our aim was to undertake global and sex-specific genome-wide epigenomic studies (EWAS) in a Mediterranean population to identify the main smoking DNA-methylated genes. Methods We analyzed 88 participants in the…

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

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…

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

[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.
