Thesis Abstract

Abstract
This thesis investigates the impact of plant-based diets on gut microbiota composition and health outcomes in adults. The global rise in chronic diseases has prompted a growing interest in dietary patterns that may positively influence health. Plant-based diets, characterized by a high consumption of fruits, vegetables, whole grains, nuts, and seeds, have been associated with numerous health benefits. One key mechanism through which plant-based diets exert their effects is by modulating the composition and function of the gut microbiota, a complex community of microorganisms residing in the gastrointestinal tract. The gut microbiota plays a crucial role in maintaining gut health, immune function, metabolism, and overall wellbeing. Chapter 1 provides an introduction to the topic, highlighting the background of the study, the problem statement, research objectives, limitations, scope, significance, structure of the thesis, and key definitions. Chapter 2 presents a comprehensive literature review, examining existing studies on plant-based diets, gut microbiota, and health outcomes in adults. The review identifies gaps in the current knowledge and sets the stage for the research methodology outlined in Chapter 3. Chapter 3 details the research methodology, including the study design, participant recruitment, dietary assessment methods, gut microbiota analysis techniques, and statistical analysis plan. The methodology aims to elucidate the relationship between plant-based diets, gut microbiota composition, and various health parameters in a cohort of adult participants. Chapter 4 presents the findings of the study, analyzing the impact of plant-based diets on gut microbiota composition and health outcomes in adults. The results provide insights into the specific microbial changes associated with plant-based dietary patterns and their implications for metabolic health, inflammation, and disease risk. Finally, Chapter 5 offers a conclusion and summary of the thesis, highlighting key findings, implications for public health and clinical practice, and recommendations for future research. This thesis contributes to the growing body of evidence supporting the beneficial effects of plant-based diets on gut microbiota composition and health outcomes in adults, underscoring the importance of dietary interventions in promoting overall health and well-being.
