The Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet is a brain-focused dietary pattern designed to prevent cognitive decline in older adults. This systematic review, conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, aimed to examine the association between the MIND diet and cognitive function in older adults. Relevant studies published between 2015 and 2024 were identified through comprehensive searches of PubMed and the Cochrane Library using keywords including “MIND diet,” “cognitive performance,” and “older adults.” From a total of 138 records screened, 11 studies met the inclusion criteria after excluding reviews, meta-analyses, editorials, and those incorporating other lifestyle interventions such as physical activity or education. These studies included 7 prospective cohort studies, 2 cross-sectional studies, 1 randomized controlled trial (RCT), and 1 case-control study, comprising a total of 17,201 participants aged 57–91 years. Across studies, at least 57% of participants were women, and in the 5 studies reporting race, more than 75% were White. Dietary intake and MIND adherence were assessed primarily via food frequency questionnaires, while cognitive outcomes were evaluated using validated instruments including the Montreal Cognitive Assessment, global cognition scores, Consortium to Establish a Registry for Alzheimer’s Disease tests, and magnetic resonance imaging. Six cohort and two cross-sectional studies reported significant associations between higher MIND adherence and better cognitive outcomes. One cohort study and the single RCT showed no effect. Excluding 2 studies with short durations (≤ 3 years), the remaining nine studies suggest consistent cognitive benefits of MIND adherence. Future studies should include systematic reviews and large-scale RCTs focusing on Asian populations.
This systematic review and meta-analysis study aimed to evaluate the effectiveness of flaxseed supplementation on blood pressure (BP) in patients with hypertension based on the data from randomized clinical trials (RCTs). Three databases (PubMed [MEDLINE], Scopus, and ISI Web of Science) were searched from inception up to August 10, 2024. Relevant studies meeting our eligibility criteria were obtained. A random-effects model was used to estimate pooled weighted mean differences (WMDs) with 95% confidence intervals (CIs). The methodological quality of individual studies was assessed using the Cochrane Collaboration risk of bias tool. A total of 5 studies were included and analyzed using STATA software version 12. The results show that there is a significant decrease in systolic BP (WMD, −8.64 mmHg; 95% CI, −15.41 to −1.87; p ≤ 0.001) and diastolic BP (WMD, −4.87 mmHg; 95% CI, −8.37 to −1.37; p = 0.006) of patients with hypertension as compared to control groups. This study supported that flaxseed supplementation had favorable effects on BP control in hypertensive patients. It may be a promising adjuvant therapy for patients with hypertension.

Despite controversies, no earlier study has systematically summarized findings from earlier studies on the effect of artichoke supplementation on blood pressure. Therefore, current systematic review and meta-analysis was done on the effect of artichoke supplementation on systolic blood pressure (SBP) and diastolic blood pressure (DBP) in adults. Five databases were searched from inception to January 2022 using relevant keywords. All randomized clinical trials investigating the impact of oral artichoke supplementation on any of the blood pressure parameters including SBP or/and DBP were included. Out of 1,507 citations, 7 trials that enrolled 472 subjects were included. Artichoke supplementation resulted in significant reduction in SBP (weighted mean difference [WMD], −2.01 mmHg; 95% confidence interval [CI], −3.78, −0.24; p = 0.026) and DBP (WMD, −1.45 mmHg; 95% CI, −2.81, −0.08; p = 0.038). Greater effects on SBP were detected in trials using ≤ 500 mg artichoke, lasted > 8 weeks, participants aged < 50 years’ old and sample size ≤ 70. There was also a similar impact of artichoke on DBP. However, significant non-linear associations were found between artichoke supplementation dosage and study duration with both SBP (for dosage: pnon-linearity = 0.002, for duration: pnon-linearity = 0.016) and DBP (for dosage: pnon-linearity = 0.005, for duration: pnon-linearity = 0.003). We found a significant reduction in both SBP and DBP following artichoke supplementation in adults. It could be proposed as a hypotensive supplement in hypertension management.

In this study, the association between dietary pattern and lifestyle in predicting hypertension (HTN) among 425 overweight and obese children and adolescents aged 6 to 18 years was evaluated. In the current cross-sectional study, the lifestyle-scoring algorithm was developed considering the Iranian Health Reform Plan (HRP) criterion. HTN was defined according to standard protocols. Hierarchical linear regression models were used for the analysis. The prevalence of overweight/obesity was 5.82%. The results showed that systolic and diastolic blood pressure (SBP, DBP) had significant positive correlation with age (p < 0.001 and p < 0.001) and body mass index (BMI) (p < 0.005 and p < 0.007), respectively. Moreover, DBP had a significant correlation with fruit consumption of less than 2 servings per day versus no consumption (p = 0.014, B = 0.444), fruit consumption of more than 2 servings per day versus no consumption (p = 0.014, B = 0.480), and vegetable consumption less than 3 servings per day versus no consumption (p = 0.045, B = −0.374). Moreover, DBP had a significant correlation with fast foods/junk foods consumption of 1–2 items per week versus almost daily consumption (p = 0.047, B = −0.177). The final model could predict 32.1% of HTN by SBP and DBP (R2 = 0.32). According to our findings, lower intake of vegetables and fruits, higher amounts of fast foods, higher age and BMI could be potent predictors of high blood pressure among Iranian children and adolescents.

Hypertension is a major health issues globally. Multiple genetic and environmental factors are involved in hypertension etiology.

In this study, we investigated whether the single nucleotide polymorphisms (SNPs) associated with telomere length (TL) were associated with the incidence of hypertension (HTN)/coronary heart disease (CHD) and cardiovascular risk factors in the Korean population. Data from 5,705 (ages 39–70) participants in the Korean Genome Epidemiology Study (rural Ansung and urban Ansan cohorts) were studied. Twelve SNPs known to be associated with telomere biology were tested for an association with HTN/CHD. As results, no significant associations were found between the selected TL-related SNPs and prevalence of HTN and CHD. Among non-alcohol users, subjects with minor alleles in rs1269304 and rs10936601 (

High sugar intake has been suggested to be related to hypertension. To examine the associations between intakes of sugar and sugar-sweetened beverages (SSBs) and the prevalence of hypertension, we used the US National Health and Nutrition Examination Survey (NHANES) 2003-2006. A total of 3,044 participants aged ≥19 years were included. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) using multivariate logistic regression model. Prevalent hypertension cases were defined as systolic blood pressure (SBP) of ≥140 mmHg or diastolic blood pressure (DBP) of ≥90 mmHg. In the multivariate adjusted models, we observed no association between sugar consumption and the prevalence of hypertension. In the model where we adjusted for age, gender, NHANES period and BMI, those who consumed ≥3 times per day of sugar-sweetened beverages had an OR of 1.87 (95% confidence interval, CI = 1.06-3.26) for the prevalence of hypertension compared with those who consumed <1 time per month of these beverages. Further adjustment for other factors attenuated the association; ORs (95% CIs) were 1.21 (0.81-1.81) for 1 time per month-<3 times per week, 1.39 (0.86-2.24) for 3 times per week-<1 times per day, 1.26 (0.80-1.98) for 1-<3 times per day, and 1.50 (0.84-2.68) for ≥3 times per day of sugar-sweetened beverages compared to the <1 time per month (p for trend = 0.33). In conclusion, we found that sugar consumption was not associated with the prevalence of hypertension, however there was suggestion that high sugar-sweetened beverage consumption was associated with high prevalence of hypertension in the US.
