Organic food consumption was measured based on two questions in the FFQs:“In the last year, have you eaten any organic food? (Yes/No)” “Which organic food have you eaten in the last year?” with categories including milk, eggs, meat, fruits, vegetables, bread/cereals, and prepared frozen meals. The beta coefficients (β) represent the association between organic food consumption and cognitive test performance at baseline (before tests were conducted). In other words, a beta coefficient of ~0.3–0.4 means that, on average, organic consumers score about 0.3 to 0.4 points higher on the cognitive tests compared to non-organic consumers. Included above is a summary table listing the analysis type (cross-sectional versus longitudinal), exposure to organic food, tested outcome (cognitive score, incident MCI), and key results.
