As Marion Nestle notes in Eat Drink Vote "Food marketers, of course, are in business and always looking for ways to cut costs and increase profits."
Yes, food marketers aim to make products that people want but their ability to stay in business depends on their ability to make a profit. So, profit has to be the first objective. When consumers account for the profit motive, they can look at food marketing and packaging through a slightly different lens. Additionally, consumers can act on this knowledge by "voting" with their purchases for those companies that work to promote the health of their customers and the planet.
