Here's a simple test to determine if your kid eats enough vegetables: Grab a vegetable out of the fridge . . . anything . . . and then ask your kid what it is. If they DON'T KNOW, they're not eating enough vegetables. A study put a ZUCCHINI in front of young people between the ages of 15 and 24, and asked them what it was. And the good news is: 80% correctly ID'd it. About 18% thought it was a cucumber. Which . . . okay that's fair. Another 2% thought the zucchini was "an eggplant." Also in the study: 12% of 15- to 24-year-olds couldn't correctly ID a grapefruit. And 4% didn't know what a cauliflower was.
