Not particularly surprising. Note that exercising more, consuming fewer calories, not smoking and not being depressed seemed to be more important. (And not having APOE4, but we can't control that factor.)
From the Results section:
In the vegetable and fruit subgroups analyses, we found that higher consumption of green leafy vegetables, carotenoid-rich vegetables, and berry fruits were significantly associated with reduced odds of both moderate and poor SCF (table 4). No significant associations were observed for cruciferous vegetables, starchy vegetables, citrus fruits, and other noncitrus fruits subgroups. The associations for total juice was mainly observed for orange juice intake, whereby participants with daily consumption had a substantially lower odds of poor SCF (0.53 [0.43–0.67], p trend <0.001) compared to those with no or <1 serving/mo intake (table 5). When evaluating the associations with intakes of individual vegetables, fruits, and fruit juices, we observed that tomatoes, lettuce, brussels sprouts, peppers, cantaloupe, and strawberries were associated with significantly lower odds of moderate and poor SCF, and especially strong associations were seen for tomato sauce and orange juice (figure).
