Abstract

Purpose: This review aims to compare the magnitude of the effects of chronic consumption of fruits; specifically berries, citrus and cherries on cardiovascular disease (CVD) risk factors. Methods: PubMed, Web of Science, Scopus, and psycARTICLES were searched from inception until January 2020. Forty-five chronic ( 1 week) randomised controlled trials assessing CVD risk factors including endothelial (dys)function, blood pressure (BP), blood lipids and inflammatory biomarkers were included. Results: Investigated interventions reported improvements in endothelial function (n = 8), inflammatory biomarkers and lipid status (n = 14), and BP (n = 10). Berries including juice of barberry, cranberry, grape, pomegranate, powder of blueberry, grape, raspberry and freeze-dried strawberry significantly reduced SBP by 3.68 mmHg (95% CI - 6.79 to - 0.58; P= 0.02) and DBP by 1.52 mmHg (95% CI - 2.87 to - 0.18, P = 0.04). In subgroup analysis, these associations were limited to cranberry juice (SBP by 1.52 mmHg [95% CI - 2.97 to - 0.07); P = 0.05], DBP by 1.78 mmHg [95% CI - 3.43 to - 0.12, P = 0.04] and cherry juice (SBP by 3.11 mmHg [95% CI - 4.06 to - 2.15; P = 0.02]). Berries also significantly elevated sVCAM-1 levels by 14.57 ng/mL (85% CI 4.22 to 24.93; P = 0.02). Conclusion: These findings suggest that supplementing cranberry or cherry juice might contribute to an improvement in blood pressure. No other significant improvements were observed for other specified fruits. More research is warranted comparing different classes of fruit and exploring the importance of fruit processing on their cardiovascular-protective effects.

Abstract

Purpose: The purpose of this paper with meta-analysis is to clarify the effects of cranberry consumption on features of the metabolic syndrome of interest of all relevant randomized controlled trials (RCTs). Design/methodology/approach: A systematic literature search was conducted on ISI web of science, PubMed, Embase, the Cochrane library and Google Scholar databases, to include trials published up to March 2019. Weighted mean differences (WMD) were calculated from a random or fixed-effects models. Between-study heterogeneity was assessed by Cochrane's test and I2 index. Findings: Ten RCTs were included in this review which involving a total of 371 subjects. Our meta-analysis showed that cranberry consumption had beneficial effects on waist circumference (WMD -0.49, 95% CI -0.96 to -0.036; p = 0.034). No significant effect of cranberry consumption on fasting blood glucose, high-density lipoprotein cholesterol, triglycerides and blood pressure was found in this meta-analysis. Originality/value: To the best of the authors' knowledge, this is the first systematic review with meta-analysis of RCTs that investigate the effect of cranberry consumption on features of the metabolic syndrome.

Berries and their polyphenols as a potential therapy for coronary microvascular dysfunction: a mini-review
Abstract

Ischemia with no obstructive coronary artery disease (INOCA) is a common diagnosis with a higher prevalence in women compared to men. Despite the absence of obstructive coronary artery disease and no structural heart disease, INOCA is associated with major adverse cardiovascular outcomes as well a significant contributor to angina and related disability. A major feature of INOCA is coronary microvascular dysfunction (CMD), which can be detected by non-invasive imaging and invasive coronary physiology assessments in humans. CMD is associated with epicardial endothelial-dependent and -independent dysfunction, diffuse atherosclerosis, and left-ventricular hypertrophy, all of which lead to insufficient blood flow to the myocardium. Inflammatory and oxidative stress signaling, upregulation of the renin-angiotensin-aldosterone system and adrenergic receptor signaling are major drivers of CMD. Treatment of CMD centers around addressing cardiovascular risk factors; however, there are limited treatment options for those who do not respond to traditional anti-anginal therapies. In this review, we highlight the ability of berry-derived polyphenols to modulate those pathways. The evidence supports the need for future clinical trials to investigate the effectiveness of berries and their polyphenols in the treatment of CMD in INOCA patients.

Abstract

The existence of a relationship between the consumption of dietary berries and blood pressure reduction in humans has been repeatedly hypothesized and documented by an increasing body of epidemiological and clinical evidence that has accumulated in recent years. However, results are mixed and complicated by a number of potentially confounding factors. The objective of this article is to review and summarize the available clinical evidence examining the effects of berry consumption on blood pressure regulation as well as the prevention or treatment of hypertension in humans, providing an overview of the potential contribution of distinctive berry polyphenols (anthocyanins, condensed tannins and ellagic acid), and results of dietary interventions with blueberries, bilberries, cranberries, raspberries, strawberries, chokeberries, cherries, blackcurrants and acai berries. We conclude that, while there is insufficient evidence supporting the existence of a direct blood pressure lowering effect, there is stronger evidence for specific types of berries acting indirectly to normalize blood pressure in subjects that are already hypertensive.

Abstract

BACKGROUND & AIMS: The impetus for the current study was to evaluate the efficacy of cranberry supplementation on cardiovascular disease metabolic risk factors in adult populations.METHODS: A systematic review was conducted on PubMed, Scopus, Web of Science and Google Scholar up to June 2018, to identify randomized controlled trials investigating the effect of cranberry supplementation on cardiovascular metabolic risk factors.RESULTS: The results of the pooled effect size indicated that cranberry administration significantly reduced systolic blood pressure and body mass index. No statistically significant change was observed in triacylglycerol, total cholesterol, low-density lipoprotein, high-density lipoprotein, fasting plasma glucose, fasting insulin, homeostasis model assessment of insulin resistance, diastolic blood pressure, waist circumference, C-reactive protein, and intercellular adhesion molecule. Stratified analysis showed that SBP reduction was more pronounced in studies with >=50 mean age participants. Also, subgroup analysis suggested a significant increase in high-density lipoprotein concentrations in subgroups with subjects <50 mean age, and triacylglycerol levels in subsets with cranberry administered in juice form.CONCLUSIONS: This systematic review and meta-analysis suggests cranberry supplementation may be effective in managing systolic blood pressure, body mass index and high-density lipoprotein in younger adults. Further high-quality studies are needed to confirm these results.

Abstract

The main goal of this work was to clarify the effects of the consumption of berries on cardiovascular disease (CVD) risk factors by performing a systematic review according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) statement, followed by a meta-analysis and a trial sequential analysis (TSA) of randomized controlled trials (RCTs). The electronic search was conducted in PubMed, Scopus, SciELO, Web of Science and Cochrane Library between April and June 2016. To be included, RCTs had to report 1 or more of the following outcomes: total cholesterol (TC), HDL-cholesterol (HDL), LDL-cholesterol (LDL), triglycerides (TG), blood pressure (BP), C-reactive protein (CRP), tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6), vascular cell adhesion molecule-1 (VCAM), intercellular adhesion molecule-1 (ICAM), glucose, insulin, apolipoprotein A-I (Apo A-I) or apolipoprotein B (Apo B). It was observed that the intake of berries reduces TC, LDL, TG, and BP while increasing the level of HDL, suggesting a beneficial effect on the control of CVDs' risk factors. Thus, the intake of berries as nutraceuticals or functional foods could be suggested for the prevention and control of CVDs.

Abstract

INTRODUCTION: Hyperlipidemia, obesity, hypertension, and diabetes are the most important risk factors for cardiovascular diseases. The aim of this systematic review article is to introduce the medicinal plants that exert significant clinical effects on hypertension, hyperlipidemia, obesity, and diabetes. METHODS: In this review article, the international research databases including MEDLINE, Google scholar, EBSCO, Academic Search, Web of Science, SciVerse, Scopus (SCOPUS), EBSCO, Academic Search, Cochrane, Central Register of Controlled Trials (CENTRAL) and a Chinese database (China Network Knowledge Infrastructure [CNKI]) were searched using the key words hyperlipidemia, hypertension, diabetes, herbal, obesity, and phytomedicine, matched by MESH, from their respective inceptions up to March, 2016. The plants that were effective on one, two, three, or all of four diseases were determined. The doses, side effects, the most important pharmaceutically effective compounds, the used organs, and important points regarding usage were separately recorded. Also known clinically significant interactions were presented. RESULTS: 1023 articles were found to be about medicinal plants and hypertension, 1912 articles about medicinal plants and hyperlipidemia, 810 articles about medicinal plants and obesity, 1174 articles about medicinal plants and diabetes. Of 144 plants included in the analysis, 83 were found to be effective on hyperlipidemia, 100 on hypertension, 66 on obesity, and 72 on diabetes. 43 plants were found to be effective on two diseases, 14 on three diseases, and 34 on all four diseases. Three plants (Tomato, Cranberry and Pomegranate), in food and therapeutic doses, were found to be used to treat cardiovascular diseases especially in pre-eclampsia and hyperlipidemia in pregnancy. CONCLUSION: Regarding the findings of this study, we can argue that the medicinal plants, other than monotherapy, can be used as poly-therapy, to treat cardiovascular diseases.

Abstract

Berries are a rich source of (poly)phenols, including anthocyanins, flavan-3-ols, procyanidins, flavonols, ellagitannins, and hydroxycinnamates. Epidemiological evidence indicates that the cardiovascular health benefits of diets rich in berries are related to their (poly)phenol content. These findings are supported by small-scale randomized controlled studies (RCTs) that have shown improvements in several surrogate markers of cardiovascular risk such as blood pressure, endothelial function, arterial stiffness, and blood lipids after acute and short-term consumption of blueberries, strawberries, cranberries, or purified anthocyanin extracts in healthy or diseased individuals. However, firm conclusions regarding the preventive value of berry (poly)phenols cannot be drawn due to the small number of existing studies and limitations that apply to the available data, such as lack of controls or failure to assess the absorption and metabolism of (poly)phenols. Although the current evidence is promising, more long-term RCTs are needed to establish the role of berry (poly)phenols to support cardiovascular health.
