But why do these companies market the sugary stuff to mothers, instead of the healthy stuff they also sell? The report doesn't offer an answer, but the obvious conclusion is a compelling one. If you get kids used to eating healthy, pure vegetables and fruits, then they may develop a life-long habit of eating natural produce. But if you get them on processed foods early, then they'll be on them for life. Just think how strong the nostalgic pull is for the fruits of your childhood. That's a powerful ally when selling junk food to adults.
