Dietary Approaches and Health Outcomes

Dietary Approaches and Health Outcomes

Welcome to the Dietary Approaches and Health Outcomes Project

The 2013 Academy of Nutrition and Dietetics Position Paper titled “Total Diet Approach to Healthy Eating” stated ‘… that the total diet or overall pattern of food eaten is the most important focus of health eating.” 

The public is bombarded with conflicting nutrition information, especially with what foods to eat or which diets to follow. According to a 2018 online survey conducted by Food Insight of 1,009 Americans between 18 and 80 years old, 80% of the participants strongly/somewhat agree that “there is a lot of conflicting information about what foods I should eat or avoid.” While some diets are beneficial for individuals with a specific health condition, their health benefits on healthy individuals may not be the same. Yet, the strength and availability of evidence to substantiate those statements remain a question. 

The EAL will conduct a systematic review on several popular diets to examine their health effects among healthy adults to provide more concrete evidence for RDNs and their clients.

Scoping Review

Phase I of the systematic review is the scoping review. Started in January 2020, it is designed to examine the availability of literature examining diet or energy restriction interventions. The results of the scoping review will be used to guide the focus of the systematic review, including the development of the research questions.
