Cs. Johnston et al., More Americans are eating "5 a day" but intakes of dark green and cruciferous vegetables remain low, J NUTR, 130(12), 2000, pp. 3063-3067
Epidemiological investigations repeatedly show that the regular consumption
of dark green and cruciferous vegetables, tomatoes and citrus fruits in pa
rticular is related to reduced cancer risk. We used the 1994-1996 Continuin
g Survey of Food Intakes by Individuals to examine the types of fruits and
vegetables consumed by Americans. The analytic sample population, which con
sisted of 4806 men and women (25-75 y old) who completed two nonconsecutive
24-h recalls, consumed 3.6 +/- 2.3 servings of vegetables and 1.6 +/- 2.0
servings of fruit daily. iceberg lettuce, tomatoes, French fried potatoes,
bananas and orange juice were the most commonly consumed fruits and vegetab
les, accounting for nearly 30% of all fruits and vegetables consumed. The m
ost popular items, lettuce and tomatoes, were consumed by 39-42% of the sam
ple population during the reporting period. Fewer respondents (16-24%) cons
umed French fried potatoes, bananas or orange juice. Only 3% of the sample
consumed broccoli during the reporting period. White potato consumption ave
raged 1.1 servings daily, with French fried potatoes representing 0.4 servi
ng. Tomato product consumption averaged 0.5 serving daily, dark green veget
able consumption averaged 0.2 serving daily and citrus, berries or melon co
nsumption amounted to nearly 0.8 serving daily. These data indicate that Am
ericans are consuming more fruits and vegetables but that dark green and cr
uciferous vegetable intake is low.
