The Impact of Plant-Based Diets on Cardiovascular Health in Adults: A Systematic Review and Meta-Analysis

Thesis Abstract

Abstract
The prevalence of cardiovascular diseases (CVD) is a significant global health concern, necessitating exploration of dietary interventions to mitigate risk factors and improve cardiovascular health. This thesis presents a systematic review and meta-analysis investigating the impact of plant-based diets on cardiovascular health in adults. The study aims to synthesize existing evidence on the effects of plant-based diets on CVD risk factors, such as blood pressure, cholesterol levels, and inflammatory markers. Chapter 1 provides an introduction to the research topic, outlining the background, problem statement, objectives, limitations, scope, significance, and structure of the thesis. Chapter 2 presents a comprehensive literature review covering ten key studies on plant-based diets and cardiovascular health. The review explores the mechanisms through which plant-based diets influence cardiovascular risk factors and outcomes. Chapter 3 details the research methodology employed in this study, including study design, search strategy, inclusion and exclusion criteria, data extraction methods, and statistical analysis techniques. The chapter also discusses potential biases and limitations in the methodology and data analysis process. Chapter 4 presents the findings of the systematic review and meta-analysis, synthesizing the results of the included studies to assess the overall impact of plant-based diets on cardiovascular health outcomes. The chapter discusses the effects of plant-based diets on blood pressure, lipid profiles, inflammation, and other relevant biomarkers associated with CVD risk. Chapter 5 concludes the thesis by summarizing the key findings, discussing their implications for clinical practice and public health interventions, and highlighting areas for future research. The study underscores the potential of plant-based diets as a promising dietary strategy for improving cardiovascular health in adults and calls for further investigation into the optimal composition and implementation of plant-based dietary interventions. Overall, this thesis contributes to the growing body of evidence supporting the role of plant-based diets in promoting cardiovascular health and provides valuable insights for healthcare professionals, policymakers, and individuals seeking to adopt healthier dietary patterns to prevent and manage cardiovascular diseases.
