Eating is addictive but sugar and fat are not like drugs, study says
Study examines 'food addiction'

(Medical Xpress)—People can become addicted to eating for its own sake but not to consuming specific foods such as those high in sugar or fat, research suggests.

An international team of scientists, including researchers from Aberdeen, has found no strong evidence for people being addicted to the in certain foods.

The brain does not respond to nutrients in the same way as it does to addictive drugs such as heroin or cocaine, the researchers say.

Instead, people can develop a psychological compulsion to eat, driven by the that the brain associates with eating.

This is a behavioural disorder and could be categorised alongside conditions such as , say scientists at the University of Edinburgh.

They add that the focus on tackling the problem of obesity should be moved from food itself towards the individual's relationship with eating.

The study, which examined the for as a substance-based addiction, is published in Neuroscience & Biobehavioral Reviews.

The researchers also say that the current classification of mental disorders, which does not permit a formal diagnosis of eating addiction, could be redrawn. However, more research would be needed to define a diagnosis, the scientists add.

The work was carried at the Universities of Edinburgh, Aberdeen, Gothenburg, Essen, Utrecht and Santiago de Compostela.

The researchers are involved in the NeuroFAST consortium, which is an EU-funded project studying the neurobiology of eating behaviour, addiction and stress.

Dr John Menzies, Research Fellow in the University of Edinburgh's Centre for Integrative Physiology, said: "People try to find rational explanations for being over-weight and it is easy to blame food.

"Certain individuals do have an addictive-like relationship with particular foods and they can over- despite knowing the risks to their health. More avenues for treatment may open up if we think about this condition as a behavioural addiction rather than a substance-based addiction."

Professor Suzanne Dickson, of the University of Gothenburg and co-ordinator of the NeuroFAST project, added: "There has been a major debate over whether sugar is addictive. There is currently very little evidence to support the idea that any ingredient, food item, additive or combination of ingredients has addictive properties."

Professor Julian Mercer of the University of Aberdeen, Rowett Institute of Nutrition and Health, said "The concept of 'food addiction' has been widely and frequently reported in the media, and it would be easy to form the view that this provides an explanation for the weight problems that many people experience. However, most individuals with a weight problem, if this is how we are going to describe the more than 50% of the population who are either overweight or obese, put on weight rather slowly over periods of years or decades, and for these people it is almost certainly completely inappropriate to suggest that food addiction or eating has any role to play"

It might be better to describe this as the addictiveness of *excessive eating*.

Great theory, but I don't believe it.

If specific ingredients don't cause addictiveness in food, they why is there so much unneccessary sugar put in foods on purpose.

Food manufacturers know that sugary foods are addictive, and it is also cheap to load junk foods with sugary junk, which contributes greatly to the obesity and gluttony epidemic around the world. Cheap in, expensive out, just like true capitalism.

Re: "The brain does not respond to nutrients in the same way as it does to addictive drugs..."

The response to nutrients is epigenetically linked from the effects of odors on hormones that affect behaviors associated with nutrient uptake. Researchers who do not understand the difference between an epigenetic effect and what leads to an affect on hormone-organized and hormone-activated behavior are confusing others with their misrepresentations of how nutrient excess (stress) or starvation (stress) are linked from food odors and social odors to hormones and behaviors.

Serious scientists, like Bruce McEwen see: http://www.pnas.o...pdf+html (link opens pdf) have tried to teach others the biological basis of addictions. "The authors note that on page 17184, right column, first paragraph, line 4, "effect" should instead appear as "affect."

Social scientists don't want others to learn about molecular biology since it explains everything they can't.
