|---|---|---|---|---|---|---|
| Serum Lipid | Mean (SD) | Mean (SD) | Mean (SD) | Mean (SD) | F | p |
| Total cholesterol | 153.3 (27.5)a | 145.0 (23.0) | 144.2 (22.4) | 143.7 (23.2) | 4.4 | .006 |
| High-density lipoprotein | 44.9 (13.5) | 43.2 (18.4) | 43.0 (13.3) | 43.0 (13.8) | 0.37 | .773 |
| Low-density lipoprotein | 82.0 (26.1) | 78.1 (16.0) | 79.3 (21.1) | 80.0 (20.0) | 0.43 | .733 |
| Triglycerides | 136.2 (77.5)a | 101.2 (63.7) | 111.1 (64.7) | 110.6 (65.5) | 4.9 | .003 |
Note. N = 37. df = 3. p < .05 indicates significance.

Post hoc test results: The control diet resulted in significantly (p < .05) higher total cholesterol and serum triglyceride levels in comparison to the low-fat, high-SFA, and high-PUFA diets.
