Wealthy Kids Acquire a Taste for Healthier Foods Because of Food Waste

But those kids can learn to like [brocolli], eventually: One 1990 study found that kids need to be presented with unknown foods somewhere between eight and 15 times before they come to accept them. This, of course, doesn’t come cheap. Once rejected, a good number of those eight to 15 servings of broccoli (or carrots or whole grains or fish) are going to end up on the floor and then in the garbage. And on top of that, parents need to buy a dependable backup food to have on hand.

Who can afford that sort of waste? Not parents with tight food budgets. A recently published study looking into the eating and shopping habits of both low-income and high-income parents suggests that the steep up-front cost of introducing foods to children is enough to deter a number of parents from trying. This cost-cutting decision may explain some of the differences between how rich and poor Americans eat.
