Baseline | Intervention | Washout | Baseline | Intervention | Washout | Between-group intervention P | |
Fruit and vegetables (servings/d) | 2.9 ± 0.3 (18) | 3.4 ± 0.4 (17) | 2.6 ± 0.3 (15) | 2.7 ± 0.3 (17) | 4.8 ± 0.3* (17) | 2.7 ± 0.3 (16) | 0.001 |
Vitamin C (mg/d) | 28.6 ± 3.1 (18) | 73.4 ± 4.2* (17) | 31.4 ± 5.1 (15) | 29.1 ± 3.1 (17) | 214 ± 4.5* (17) | 28.8 ± 4.3 (16) | <0.0001 |
All values are means ± SEMs; n in parentheses. For 0.5- compared with 2-kiwifruit/d groups after intervention, P values were determined by using the unpaired t test. *For intervention compared with baseline, P < 0.0001 (paired t test).
