Review of the preceding studies on dietary habits that help prevent lifestyle diseases and reduce medical expenses ―Toward the implementation of science-based dietary education―

摘要

We analyzed extant research to identify dietary habits that reduce medical expenses. We determined diseases and symptoms that strongly affect medical expenses through the examination of extant research. We subsequently extracted the means of prevention of these diseases and symptoms, and dietary habits whose beneficial effects have been scientifically verified.Reducing the intake of high-calorie foods and sweet drinks, eating at least 400g of fruits and vegetables per day, minimizing the intake of salted foods and table salt, and reducing the intake of red meat and avoiding processed meat were extracted as dietary habits that help reduce medical expenses.
