Thesis Abstract

Abstract
This thesis presents a comprehensive investigation into the impact of plant-based diets on cardiovascular health in older adults through a systematic review and meta-analysis. Cardiovascular disease remains a significant global health concern, particularly among aging populations. The adoption of plant-based diets has gained attention for its potential cardiovascular benefits due to the abundance of nutrients and phytochemicals present in plant foods. The aim of this study is to synthesize existing research findings to provide a clearer understanding of the relationship between plant-based diets and cardiovascular health in older adults. The thesis begins with an introduction that sets the context for the study, followed by a detailed background of the research topic. The problem statement highlights the gaps in current literature regarding the specific effects of plant-based diets on cardiovascular health in older adults. The objectives of the study are outlined to guide the research process, while the limitations and scope of the study are also defined. The significance of the study is discussed to emphasize the potential contributions to the field of nutrition and dietetics. The structure of the thesis is presented to provide an overview of the chapters, and key terms are defined to ensure clarity of terminology. Chapter two consists of a comprehensive literature review that examines previous studies on plant-based diets and their effects on cardiovascular health in older adults. Ten key themes are identified and analyzed to provide a foundation for the research methodology in chapter three. The research methodology section outlines the study design, data collection methods, inclusion criteria, and statistical analysis techniques used in the systematic review and meta-analysis. Chapter four presents a detailed discussion of the findings obtained from the systematic review and meta-analysis. The results are analyzed in relation to the research objectives, highlighting the impact of plant-based diets on cardiovascular risk factors such as blood pressure, cholesterol levels, and inflammatory markers. The implications of the findings are discussed in the context of promoting cardiovascular health in older adults through dietary interventions. Finally, chapter five concludes the thesis by summarizing the key findings and implications of the study. Recommendations for future research and practical applications in clinical practice are provided to guide further investigation and implementation of plant-based dietary interventions for improving cardiovascular health in older adults. Overall, this thesis contributes to the growing body of evidence supporting the benefits of plant-based diets in promoting cardiovascular health among aging populations.
