That young children dislike broccoli is a commonly held assumption. Many parents know that is entirely untrue, as their small children gobble up the little trees with abandon. USDA offers consumption statistics that help inform this question. It turns out that young children, both boys and girls eat nearly as much broccoli among their vegetables as adults to. The drop occurs with teenagers, particularly boys. Young women start eating broccoli sooner than young men, but it becomes a larger part of their vegetable consumption as they get older.
The statistics also show the broccoli consumption is similar among low income, mid-income, and high income consumers. There are small differences in total vegetable consumption among income groups, but not enough to support the common impression that low income consumers are not getting vegetables.
Broccoli consumption is also consistent among weight categories. There is little difference among consumers who are healthy weight, overweight, or obese. Notably, obese children eat slightly more broccoli than their lighter counterparts.
Broccoli is a large share of cooking vegetables even though it constitutes only about 4% of total vegetable consumption. The majority of vegetable consumption (58%) constitutes tomatoes and potatoes, And much of the rest (26%) are salad vegetables. Cooking vegetables constitute the remaining 16%, so broccoli share of those is significant.
