Data about root vegetables was provided by 1 cohort. Significant protective effects were found in all 3 subcohorts.
Conclusion: Consistent protective effects were found, but results were available from one cohort only. No evidence was found for an association between
root vegetables and mortality.

| 21) Nöthlings U (2008) | The EPIC Study. | 10,449 participants - aged 35 to 70- with self-reported diabetes mellitus. (10 European Countries) | 9 (1992-2000 to 2007) | 1346? | All-cause mortality | Root vegetables (not defined. excluding potatoes) | A significantly decreased risk: RR = 0.91 (0.84-0.99) for an increase of 20 g/d. | Stratified on age. Adusted for sex, smoking status, self-reported heart attack at baseline, self-reported hypertension at baseline, self-reported cancer at baseline, waist-to-hip ratio, insulin treatment, age at diabetes diagnosis, energy intake, alcohol intake. |
| 21) Agudo A. (2007) | The EPIC Study. | 41,358 subjects (15,610 men, and 25,748 women) aged 30-69. (Spain) | 6.5 (1992-96 to 2002) | 562? (295 cancer, and 123 CVD) | All cause mortality | Root vegetables (mostly tomatoes and carrots) |
HR = 0.72 (0.56-0.91; P = 0.006) for the highest vs lowest quartile of consumption. Amount specific data (median intake in g/day): 0.4: HR = 1. 2.7: HR = 0.82 (0.65-1.10). 5.9: HR = 0.80 (0.63-1.00). 24.3: HR = 0.72 (0.56-0.91). This association remained after additional adjustment for fruiting vegetables, fresh fruit, lycopene, and a total radical-trapping antioxidant parameter variable. HRs for increasing quartiles (1, 0.83 [0.66-1.05], 0.82 [0.65-1.03], and 0.76 [0.59-0.96; P = 0.021]). HR as a continuous variable: A significantly decreased risk: HR = 0.94 (0.89-1.00). This association became weaker after additional adjustment for fruiting vegetables, fresh fruit, lycopene, and a total radical-trapping antioxidant parameter variable: 0.96 (0.90-1.01). There was no effect modification by sex. | Stratified by center. Adjusted for age, sex, total energy, education, BMI, physical activity, cigarette smoking, and alcohol. |

(2007) | The Italian part of the EPIC Study. | 5,611 subjects aged ≥ 60. | 6.2 (1993-98 to 2001-02) | 152? | All-cause mortality | Root vegetables (not defined) | A significant association (P = 0.02) with reduced mortality (No data shown). | Stratified by centre. Adjusted for sex, BMI, waist, smoking status, education, civil status, hypertension at enrollment, PAL, and caloric intake. |
