How to Sneak Veggies Into Your Child's Diet
Get Out the Food Processor for a Stealth Veggie Sauce

May 1, 2007 -- Trying to boost your child's vegetable consumption? You may
want to reach for your food processor.
Kids don't necessarily notice when steamed broccoli and cauliflower are
blended into their pasta sauce, a new study shows. As a result, the kids eat
more vegetables without knowing it.
The study comes from Kathleen Leahy and Barbara Rolls, PhD, of Pennsylvania
State University. Leahy is a nutrition sciences graduate student; Rolls is a
professor of nutrition sciences.
Leahy designed the study, which included 61 children aged 3-5.
The researchers served the children lunch one day per week for four weeks.
The lunches all included a pasta dish.

The children didn't know it, but Leahy's team snuck broccoli and cauliflower
into the pasta sauces in some of the lunches.
To make the sauce, the researchers steamed frozen broccoli and frozen
cauliflower for seven minutes, following the directions on the frozen veggies'
package. Next, they used a food processor to blend the steamed broccoli and
cauliflower into the tomato sauce.
The finished sauce included "very tiny pieces" of broccoli and
cauliflower, Leahy tells WebMD. "You couldn't tell that is was in there,
visually. It was pretty imperceptible.
"We didn't tell them anything about it, and the preferences for the two
pastas were pretty much the same," Leahy says. "They didn't really
prefer one version of the pasta over the other, so both were equally
The researchers also made some of the pastas with low-fat dairy products.
Again, the children didn't notice.
The bottom line: They consumed fewer calories and more vegetables when broccoli
and cauliflower were blended into the pasta sauce.
Leahy and Rolls don't recommend trying to conceal all veggies in children's
"It is still important to keep children exposed to vegetables on a
regular basis and have them eat them with their parents," Leahy says.
Rolls agrees. "I wouldn't advocate that this is the only way parents try
to get kids to eat fruits and vegetables," she tells WebMD.
"They still need to sit down and eat fruits and vegetables, eat the real
thing, because otherwise the kid's never going to even know what a piece of
broccoli or cauliflower looks like. So this is one strategy to get their intake
up, but it shouldn't certainly be the only strategy," says Rolls, who is
also the author of The Volumetrics Eating Plan: Techniques and Recipes for
Feeling Full on Fewer Calories.
"We want them to learn to like vegetables," Leahy says.
That may take time. Research has shown that children may not try a vegetable
until they've seen it 10 to 15 times, Leahy notes.
"It's something you have to be persistent with," says Leahy, who
presented the study today in Washington at Experimental Biology 2007, an annual
meeting of several scientific societies.
