In this context Michelle Obama refers to the importance of correct information for the parents. She is not only stating the facts thar certain informations are taking for granted. That not only is important to read the labels of a product to know how many calories, or sodium it contains. She also refers on how we are all exposed to message that we don´t realize we are receiving, from choosing a meal from a menu, to when we try to get a healthy product in a store. It would probably be a lot easier to reach a can o soda than a bottle of milk, or a mac and cheese box than a whole wheat pasta. The current marketing is more oriented to unhealthy but highly commercial products , that to the ones people actually need. Parents need to know that, and that is the kind of information that they require.
