Increasing all vegetable categories by the same amount will not result in
achieving the minimum daily recommendation for the dark vegetable category (Table
5). As stated previously the gap between current and actual consumption of dark
vegetables is greatest for this sub-group. All other categories reach the recommended
levels when the increase is the same for all vegetables.

As in the case of fruits, increasing specific vegetable sub-groups (starchy, salad
and dark), and then increasing consumption of all vegetables to achieve the
recommended four servings a day increases the percentage shift of the targeted sub-
groups and lowers it for the garden vegetable category.
When the vegetable category is further disaggregated to include servings of
tomatoes and cruciferous vegetables, calculating the increases in demand become more
complicated since items such as broccoli are counted both as a serving of dark and as a
serving of cruciferous (Table 6). Because of this a dark cruciferous category was added.
