Junk Food Nearly as Addictive as Heroin
(NaturalNews) Junk food appears to be almost as addictive as heroin, according to a study conducted by researchers from the Scripps Research Institute and presented at the annual meeting of the Society for Neuroscience.
"This is the most complete evidence to date that suggests obesity and drug addiction have common neuro-biological foundations," researcher Paul Johnson said.
The researchers fed rats one of three diets: a nutritious diet, a healthy diet with restricted access to junk food, or a diet of unlimited junk food. Junk foods included cheesecake, chocolate, sponge cake and fatty meat. Mice in the third group quickly became obese, while the weight of mice in the first two groups did not change.
To test the effects of junk food on the brain's pleasure centers -- the areas affected by drugs -- the researchers electrically stimulated those areas whenever the mice ran on a wheel. The longer a rat ran on the wheel, the more pleasure it would receive.
While rats in the first two groups did not change their wheel-running behavior, the rats eating junk food soon began running on the wheel for longer periods -- suggesting that their brain's pleasure centers had become less sensitive. Consistent with this finding, the rats began eating more and more food, suggesting that their bodies had become desensitized to the pleasure the food was producing.
The researchers then began exposing rats to painful electric shocks whenever they ate junk food. The rats on the restricted junk food diet quickly stopped eating the food, but the binge-eating rats were undeterred.
"You lose control. It's the hallmark of addiction," researcher Paul Kenny said.
When the bingeing rats were deprived of junk food and given only healthy food, they refused to eat anything for two weeks.
"It's almost as if you break these things, it's very, very hard to go back to the way things were before," Kenny said. "Their dietary preferences are dramatically shifted."
"What we have are these core features of addiction, and these animals are hitting each one."

Fast food, frighteningly slow decay: Mother keeps McDonald's Happy Meal for a whole year... and it STILL hasn't gone off
Glancing at the two McDonald's Happy Meals pictured here, you may feel they look pretty much identical.
Astonishingly, however, this is the same meal, photographed 12 months apart.
Where any other food might be a mouldy, decomposing mess after a year, the McDonald's meal shows few signs of going off apart from the beef patty shrivelling and the stale burger bun cracking.
Proof, says the American nutritionist who took these photographs, that it contains so many preservatives that it is bad for the children it is aimed at.
Joann Bruso said: 'Food is supposed to decompose, go bad and smell foul eventually. The fact that it has not decomposed shows you how unhealthy it is for children.'
Mrs Bruso left the Happy Meal uncovered on a shelf at her home near Denver, Colorado, to see what would happen. She has revealed the results on her blog, in which she gives healthy eating advice to parents.
The 62-year-old, who has eight grandchildren, admitted that the arid temperature of her home near the Rocky Mountains meant there was little moisture in the air with which to speed decomposition.
But she added that during the year-long experiment, no flies or other insects were attracted to the food.
She said: 'I had the windows open many times, but flies and other insects just ignored the Happy Meal. What does that tell you, if they can't be bothered with it?
'Food is broken down into its essential nutrients in our bodies and turned into fuel. Our children grow strong bodies when they eat real food.
'If flies ignore a Happy Meal and microbes don't decompose it, then your child's body can't properly metabolise it either.
'Now you know why it's called junk food.'
McDonald's has made great efforts to show that its food is healthy amid growing concerns about childhood obesity. All its restaurants list the calories in each item as well as the individual ingredients.
Recent research showed that each product has an average of seven E numbers. The bun has several preservatives such as calcium and sodium propionate, while the pickle slice has the preservative sodium benzoate.
The fries, which Mrs Bruso said were still golden brown after a year, contain preservatives such as citric acid and sodium acid pyrophosphate, which maintains their colour.

Vitamin D better than vaccines at preventing flu, report claims
The risk of children suffering from flu can be halved if they take vitamin D, doctors in Japan have found. The finding has implications for flu epidemics since vitamin D, which is naturally produced by the human body when exposed to direct sunlight, has no significant side effects, costs little and can be several times more effective than anti-viral drugs or vaccine.
Only one in ten children, aged six to 15 years, taking the sunshine vitamin in a clinical trial came down with flu compared with one in five given a dummy tablet. Mitsuyoshi Urashima, the Japanese doctor who led the trial, told The Times that vitamin D was more effective than vaccines in preventing flu.
Vitamin D was found to be even more effective when the comparison left out children who were already given extra vitamin D by their parents, outside the trial. Taking the sunshine vitamin was then shown to reduce the risk of flu to a third of what it would otherwise be.
Altogether 354 children took part in the trial, which took place during the winter of 2008-09, before the swine flu epidemic. Vitamin D was found to protect against influenza A, which caused last year’s epidemic, but not against the less common influenza B.
The trial, which was double blind, randomised, and fully controlled scientifically, was conducted by doctors and scientists from Jikei University School of Medicine in Tokyo, Japan.
The children were given a daily dose of 1200 IUs (international units) of vitamin D over a period of three months. In the first month children in the group taking the vitamin became ill just as often as those taking the dummy tablet. But by the second month, when the vitamin level in the children’s blood was higher, the advantage of the vitamin was clear.
The Japanese scientists, writing in the American Journal of Clinical Nutrition, say that the anti-viral drugs zanamivir and oseltamivir reduce risk of flu infection by 8 per cent in children who have been exposed to infection, compared with a 50 per cent or greater reduction with vitamin D.
Anti-virals are also too expensive, and possibly too toxic, to be given to the population as a whole whereas vitamin D has additional benefits. The sunshine vitamin not only prevents bone fractures but is also believed to reduce risks of cancer, heart disease, diabetes and other illness, including various bacterial as well as viral infections.
The Japanese finding supports a theory that low blood levels of the sunshine vitamin occurring in winter explain why flu epidemics generally peak between December and March.
Vitamin D activates the innate immune system, enabling the body to produce several proteins such as defensin and cathelicidin which trigger cell activity and disable viruses.
Dr Urashima said: “Vitamin D and vaccine work by quite different mechanisms. Vitamin D enhances innate immunity while vaccine enhances acquired immunity. So we do not have to select only one way of prevention, rather we should do both ways, I think.”
Dr John Oxford, professor of virology at Queen Mary School of Medicine, London, said: “This is a timely study. It will be noticed by scientists. It fits in with the seasonal pattern of flu. There is an increasing background of solid science that makes the vitamin D story credible. But this study needs to be replicated. If it is confirmed we might think of giving vitamin D at the same time as we vaccinate.”

I think Mrs Bruso had one too many rattlesnake bites that year, I have like so many others purhased drive through maccas and found it had decompoed by the time Id got home :lol:

You might be right! I have to confess that I don't like Macca's food and the opportunity to pass on this story that a UK paper ran with was too good to miss :). In my opinion they might as well make the plates and cuttlery part of the menu - tastes about the same ;).
Oops meant to put the vitamin D story under the other post..
