This study provides a comprehensive analysis of dietary trends in the United States from 2000 to 2018, examining the population's adherence to the Dietary Guidelines for Americans (DGAs) across diverse food groups. Utilizing National Health and Nutrition Examination Survey (NHANES) data and employing meta-regression analysis, the research evaluates the intake patterns of vegetables, fruits, grains, protein, dairy, fats and oils, and key nutrients. The findings reveal a consistent and widespread non-adherence to recommended DGA servings, challenging the effectiveness of dietary guidelines in influencing public behavior. Despite revisions in guidelines, the study demonstrates remarkable stability in the intake of both recommended and discouraged foods. Additionally, the study investigates trends in obesity prevalence and BMI, suggesting that the DGAs alone may not be the primary driver of the obesity epidemic. The discussion highlights the persistent disconnect between DGA recommendations and actual dietary behaviors, emphasizing the need for public health interventions. This study contributes valuable insights into the limitations of current dietary guidelines in shaping broader dietary patterns, calling for a more holistic approach to public health interventions.
