Applying Retrospective Harmonization to the Field of Nutrition and Cognitive Health
Mapping Nutrition for a Healthier Brain
The 2020 Dietary Guidelines Advisory Committee (DGAC) explored neurocognitive health through several systematic reviews and was faced with a literature having “considerable variation in testing methods, inconsistent validity and reliability of cognitive testing methods, and differences between dietary patterns and cognitive outcomes examined,” reducing the ability to draw conclusions (USDA/HHS 2020). The lack of harmonization is a long-standing challenge in the field of nutrition and cognition, recognized over many decades. As the challenge faced by the 2020 DGAC is likely to still be in place for the 2025 DGAC’s review, one potential solution is to develop an approach to this literature.
