THE WELFARE EFFECTS OF CONSUMING A CANCER PREVENTION DIET

consumption of cabbage is equal to consumption of cabbage plus sauerkraut plus
coleslaw plus an allocation from the soup and mixed vegetable categories.

In some cases, more than one food was used to prepare the final product. When
the prepared item contained two fruits or vegetables, 50 percent of the serving was
allocated to each food item. When more than two are included, the allocation is slightly
more complicated.

The shift in demand for fruits and vegetables was determined for the fruit and
vegetable groups, and for different sub-groups. The fruit sub-groups include the
citrus/melon/berry group and all other fruit in another one. The vegetable 1 sub-
groups include starchy, salad and dark, plus a garden category for all vegetables not
included in the first three categories. For the vegetable 2 sub-groups the garden
category is further disaggregated into a tomato and cruciferous sub-group.

The shift in demand for fruits and vegetables needed to reach the minimum
recommended servings was determined after current consumption for each food item
was calculated. Three different scenarios were developed to determine this shift. The
first was to increase all items by the same amount. The second was to increase specific
sub-groups to meet targeted amounts, and then increasing all commodities equally. For
fruit, the citrus/melon/berry sub-group target needed to be met. For vegetable group
1, the sub-groups of interest are starchy, salad, and dark. These sub-groups are also
included in the vegetable group 2, plus the tomato and cruciferous targets are also met
before increasing consumption of all vegetables by the same amount. The final method
used to calculate the shift needed in consumption is to increase all sub-groups to a
