Diet myth 2: There are no bad foods, everything in moderation.
Diet facts: You may have heard that there are no good foods or bad foods, only good and bad diets. But truth be told, some foods just don't stand up nutritionally speaking. For example a potato chip can't hold a candle to a baked potato. And to say there are no bad foods might be a license for some people to eat anything whenever they want.
What's more, if having cookies in the house triggers a person to binge, then that food could be a problem simply because it results in unhealthy behaviors. Not to say you can't enjoy bad foods once in a while and in reasonable portions, but focus on eating fresh healthy foods and be aware of your own trigger foods.
