TABLE 5.
Proliferative responses to different concentrations of PHA at baseline and at the end of each diet phase of whole blood from older adults who consumed diets containing novel soybean oils differing in fatty acid composition1
| PHA | Baseline | SO | HiOleic-SO | LoSFA-SO | Hydrog-SO | LoALA-SO | P value2 |
| dpm × 103 | |||||||
| 5 mg/L | 68.6 ± 5.6c | 86.1 ± 7.2a | 84.2 ± 8.3ab | 83.2 ± 6.0ab | 73.4 ± 4.5abc | 71.4 ± 4.5bc | 0.04 |
| 10 mg/L | 59.7 ± 5.1 | 75.0 ± 6.5 | 69.7 ± 6.0 | 73.8 ± 5.6 | 68.3 ± 4.4 | 61.7 ± 2.8 | 0.10 |
| 50 mg/L | 34.3 ± 3.8 | 39.1 ± 5.2 | 35.5 ± 3.5 | 36.1 ± 2.9 | 33.4 ± 2.9 | 30.0 ± 2.0 | 0.40 |
Values are mean ± SE, n = 18. Means in a row without a common letter differ, P < 0.05. Data are corrected dpm, which is the mean dpm of mitogen-stimulated cultures minus the mean dpm of cultures without mitogens. dpm, disintegrations per minute; HiOleic-SO, high-oleic acid soybean oil; Hydrog-SO, hydrogenated soybean oil; LoALA-SO, low-α-linolenic acid soybean oil; LoSFA-SO, low-SFA soybean oil; SO, soybean oil.
P values are for the effect of the diet from ANOVA with diet as main effect and participant as repeated measure.
