For decades, tobacco companies hooked people on cigarettes by making their products more addictive. Now, a new study suggests that tobacco companies may have used a similar strategy to hook people on processed foods.

In the 1980s, tobacco giants Philip Morris and R.J. Reynolds acquired the major food companies Kraft, General Foods and Nabisco, allowing tobacco firms to dominate America’s food supply and reap billions in sales from popular brands such as Oreo cookies, Kraft Macaroni & Cheese and Lunchables.
