| Basic positive affect | 17.5 (4.1) | 16.1 (4.1) | 18.0 (3.9)a | 18.1 (3.6)a | 4.3 | .007 |
| Basic negative affect | 7.8 (2.1) | 8.1 (2.7) | 7.8 (2.4) | 7.7 (2.2) | 0.48 | .695 |
Note. N = 37. df = 3. p < .05 indicates significance. PUFA = polyunsaturated fatty acid; SFA = saturated fatty acid.

Post hoc test results: High-SFA and PUFA diets resulted in significantly (p < .05) higher basic positive affect scores.
