Non-Alcoholic Fatty Liver Disease, Diet and Contributing Factors: A Narrative Literature Review

Objectives: The purpose of this narrative literature review is to explore the relationship between Non-alcoholic fatty liver disease (NAFLD) and dietary habits, and identify factors that contribute to the development, progression, and potential management of NAFLD.

Methods: Search terms such as non-alcoholic fatty liver disease (NAFLD), diet, and nutrition, including plant-based and vegetarian diets, were used to identify 45 peer-reviewed publications published within the last five years.

Results: Dietary factors, biological, environmental, obesity, mental health, and genetic factors can contribute to the development of NAFLD. This multisystem problem can have economic, social, and psychological consequences that affect a person’s quality of life.

Conclusion: Public health personnel can educate the public about the importance of optimal nutrition and must advocate for policies to facilitate such education and awareness. Additionally, policies must allow for genetic testing in individuals and families affected by NAFLD. To address this significant public health problem, educators in all healthcare disciplines must be equipped with appropriate education.
