According to an article by author, pediatrician, and father, not only can new tastes be acquired in children of all ages, but those new tastes can include vegetables.
The trick, you see, is to start them young.
The key is desensitizing your child to new foods. According to Dr. Greene, "You can accomplish this by using the new food for the first bite of solids each day for 10 days straight."
Of course, if they are not interested in their vegetables, do not force them to eat them. But keep exposing them to healthy foods and, sooner or later, odds are they will become interested. Then all you need to do is be ready to give them more.
And, yes, this works with fruit, too. But no word on if it works with husbands.
