Food writer Bee Wilson has a message of hope for parents struggling to get their children to eat their veggies: "As parents we have a far greater power than we think we have to form children's tastes," Wilson tells Fresh Air's Terry Gross.

In her new book, First Bite, Wilson examines how genetics, culture, memory and early feeding patterns contribute to our food preferences. She says that a child's palate can be formed even before birth. And this insight can be helpful for parents who want their children to eat well and healthfully.
