Here are their findings:
The foods that ranked top of the scale contained cheese.
Cheese contains casein, present in all dairy products, and which can trigger the brain’s opioid receptors, which are linked to addiction.
The study states, “The current study provides preliminary evidence that not all foods are equally implicated in addictive-like eating behaviour, and highly processed foods, which may share characteristics with drugs of abuse (e.g. high dose, rapid rate of absorption) appear to be particularly associated with ‘food addiction’.”
So, this almost explains why we keep going back to a slice of that delicious pizza again and again! However, the scientists who did the research believe that the addiction has more to do with the processed food with high levels of sugars and fat, and it’s these ingredients that leave us coming back for another slice. In reality, it has little to do with the cheese!
