When it comes to food, all most kids care about is flavor. So how can parents, who've overcome the genetic predisposition against tart-tasting food that afflicts about 70 percent of us, compel kids to eat the healthful veggies they've been programmed to hate? A study led by Jennifer Orlet Fisher at Temple's Center for Obesity Research and Education has found that adding just 2.5 ounces of dip to a serving of vegetables could mean an 80 percent increase in vegetable consumption. Though ranch dressing was used in the experiment, Fisher notes that applesauce, hummus or a yogurt-based dip can work as well.
