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

Thesis Abstract

Abstract
This thesis investigates the impact of plant-based diets on cardiovascular health in adults through a systematic review and meta-analysis. The rising prevalence of cardiovascular diseases globally necessitates a thorough examination of dietary interventions that can positively influence cardiovascular health. Plant-based diets, which emphasize the consumption of fruits, vegetables, whole grains, nuts, and legumes while reducing or eliminating the intake of animal products, have gained attention for their potential cardiovascular benefits. This study aims to synthesize existing research to provide a comprehensive understanding of the relationship between plant-based diets and cardiovascular health outcomes in adult populations. The introduction chapter sets the stage by outlining the background of the study, stating the problem statement, objectives, limitations, scope, significance, and defining key terms. The literature review chapter critically evaluates ten key studies exploring the impact of plant-based diets on cardiovascular health indicators, such as blood pressure, cholesterol levels, and inflammatory markers. The research methodology chapter details the systematic review and meta-analysis methods employed, including search strategy, study selection criteria, data extraction, and statistical analysis techniques. Findings from the systematic review and meta-analysis are discussed in the fourth chapter, highlighting the overall effects of plant-based diets on cardiovascular health outcomes. Sub-analyses are conducted to investigate potential variations based on diet composition, study design, and participant characteristics. The results provide insights into the efficacy of plant-based diets in improving cardiovascular health and offer recommendations for future research and clinical practice. In conclusion, this thesis synthesizes current evidence on the impact of plant-based diets on cardiovascular health in adults and underscores the potential of dietary interventions in preventing and managing cardiovascular diseases. The systematic review and meta-analysis contribute to the existing literature by offering a comprehensive overview of the relationship between plant-based diets and cardiovascular health outcomes. Ultimately, this research aims to inform healthcare professionals, policymakers, and individuals about the benefits of adopting plant-based dietary patterns for promoting cardiovascular wellness in adult populations.
