The Overeaters Anonymous link has questions that can indicate a food addiction; they are similar to the questions that A.A. has for a person to determine if they are alcoholic.
Several of the questions in the first list are echoed in the part of the article I quoted.
The behaviours quoted there are, IMO, not the same as getting good nutrition. I have kept 45+ lbs off through the 12-Step recovery program. With the mental obsession removed, I can choose to eat healthily and well and even "normally", like non-addictive people.
“compulsive overeating in harmful and unhealthy ways.” The team used a measure known as the Yale Food Addiction Scale to assess symptoms of food addiction in 652 adults from Newfoundland and Labrador. The scale asks people how often they engage in certain eating habits, such as, “I eat to the point where I feel physically ill,” “I find myself constantly eating certain foods” and “I need to eat more and more to get the feeling I want.”
However, there are certain types of foods I need to stay away from; they 'trigger' me as the first drink of alcohol would trigger an alcoholic. Most food addicts find that these are refined sugars and carbohydrates.
