Insights

Tart and sweet cherry supplementation does not significantly impact blood pressure. This systematic review found no evidence that cherries lower systolic blood pressure (SBP) or diastolic blood pressure (DBP).

Area of Science:

  • Nutrition Science
  • Cardiovascular Health
  • Dietary Interventions

Background:

  • Hypertension is a significant global health concern.
  • Dietary strategies are explored to manage blood pressure.
  • Cherries are investigated for potential cardiovascular benefits.

Purpose of the Study:

  • To systematically review and meta-analyze randomized controlled trials (RCTs).
  • To evaluate the effect of tart and sweet cherry consumption on blood pressure.
  • To determine if cherry supplementation impacts systolic blood pressure (SBP) and diastolic blood pressure (DBP).

Main Methods:

  • Comprehensive literature search of PubMed, Scopus, Embase, and Web of Science databases.
  • Inclusion of randomized controlled trials (RCTs) published up to December 2020.
  • Meta-analysis of data from seven RCTs involving 201 participants.

Main Results:

  • Cherry supplementation did not result in a statistically significant reduction in SBP.
  • No significant decrease in DBP was observed with cherry intake.
  • The meta-analysis indicated no overall beneficial effect of cherries on blood pressure.

Conclusions:

  • Dietary incorporation of cherries does not appear to significantly alter blood pressure levels.
  • Current evidence does not support cherry supplementation for blood pressure management.
  • Further research may be needed to explore specific populations or preparations.

Factors affecting Blood pressure

Several physiological and lifestyle factors influence blood pressure (BP). Understanding these factors is crucial as they are significant in patient education and blood pressure management.

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Disorders of the Autonomic Nervous System01:18

Disorders of the Autonomic Nervous System

The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hypertension IV: Drug Therapy and Lifestyle Modifications

Multiple classes of antihypertensive medications are employed in treating hypertension. The most commonly recommended first-line treatments include:Thiazide Diuretics, such as chlorthalidone, increase sodium and water excretion from the body, reducing blood volume and blood pressure.Angiotensin-converting enzyme inhibitors, like lisinopril, block the conversion of angiotensin I to II, a potent vasoconstrictor lowering blood pressure.Angiotensin II Receptor Blockers (ARBs) prevent angiotensin II...
