Davis criticized the food industry of helping promote bad eating habits with misleading advertising. "It's just propaganda," she said, "that the American diet is the best in the world. Commercial people have been telling us those lies for years." In a television interview she said that a "great deal of sickness is caused by refined foods." She states that "We are literally at the mercy of the unethical refined food industry, who take all the vitamins and minerals out of food."
