Lifestyle intervention might easily improve blood pressure in hypertensive men with the C genotype of angiotensin II type 2 receptor gene

Nutrigenetics and Nutritional Strategies in Systemic Arterial Hypertension: Evidence From a Scoping Review

Nutrition and genetics have individual roles in systemic arterial hypertension (SAH); however, they can interact, influencing the regulation of blood pressure (BP) levels. The aim of this study was to evaluate the available evidence regarding gene-nutrient interactions in modulating BP levels in adults with SAH. The review followed the recommendations of the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Twelve studies met the inclusion criteria for this review, reporting on 20 genes and 31 single nucleotide polymorphisms (SNPs), with 19 of them associated with BP variations. The most frequently evaluated SNPs were ACE rs4646994 and AT1R rs5186. Among the nutritional interventions, dietary sodium content was the focus of most studies (n = 11). Interactions with sodium consumption were observed for the following SNPs: KDM1A rs587168, EDNRB rs5351, LSS rs2254524, IRS1 rs1801278, KCNK9 rs6997709, ACE rs4646994, GNB3 rs5443, PPARG rs4684847, EDN1 rs5370, BCAT1 rs7961152, IL18 rs5744292, NOS3 rs2070744, and AT1R rs5186. In the presence of a diet rich in fruits and vegetables, moderate alcohol consumption, and reduced sodium intake, the SNP AT2R rs11091046 was associated with a decrease in BP levels. Furthermore, the SNP MTHFR rs1801133 exhibited an interaction with riboflavin supplementation in affecting BP levels. The evidence regarding the interaction between genetics and diet on BP levels remains limited. Among the existing findings, an interaction was observed between sodium, calcium, riboflavin, and specific polymorphisms; however, the underlying mechanisms for these interactions have yet to be identified.

Unhealthy changes in eating habits cause acute onset hypertension in the normotensive community-dwelling elderly-3 years cohort study

The aim of this study was to determine what lifestyle changes can predict acute onset hypertension in the normotensive community-dwelling elderly.This study targeted elderly people enrolled in National Health Insurance in Fukushima Prefecture, Japan. The subjects were 24,490 people who took all of the specific health examination conducted by National Health Insurance in fiscal years 2013, 2014, and 2015 continuously and had a recorded systolic blood pressure (BP) <130 mm Hg and diastolic BP <85 mm Hg in the first 2 fiscal years. We examined their lifestyle changes for the first 2 fiscal years using the questionnaires given at the health examination. Multivariate Poisson regression analysis was conducted to examine the relationship between new-onset hypertension observed at the last examination and unhealthy lifestyle changes.The mean age of the subjects was 61.5 ± 8.2 years old at baseline. We observed new-onset hypertension in 1.062 subjects at the last examination. Of the study subjects, 12,027 (49.1%) answered to having at least one of the items of unhealthy lifestyle change in the questionnaire. In the multivariate logistic regression, eating supper before bedtime showed a significant increase in the risk ratio for acute onset hypertension (risk ratio 1.27, 95% confidence interval, 1.01-1.58).This study indicated that eating before bedtime is a risk factor of new-onset hypertension in the normotensive community-dwelling elderly. Adequate health guidance to avoid unhealthy lifestyle changes is required even in normotensive people as this hypertension is preventable.
