AMERICA: YOU ARE WHAT YOU EAT AND THAT'S A PROBLEM. Western diet? Junk food? Forget about it.

"Consuming a western diet for as little as one week can subtly impair brain function and encourage slim and otherwise healthy young people to overeat, scientists claim.
"Researchers found that after seven days on a high saturated fat, high added sugar diet, volunteers in their 20s scored worse on memory tests and found junk food more desirable immediately after they had finished a meal.
"The finding suggests that a western diet makes it harder for people to regulate their appetite, and points to disruption in a brain region called the hippocampus as the possible cause.
“'After a week on a western-style diet, palatable food such as snacks and chocolate becomes more desirable when you are full,' said Richard Stevenson, a professor of psychology at Macquarie University in Sydney. 'This will make it harder to resist, leading you to eat more, which in turn generates more damage to the hippocampus and a vicious cycle of overeating'…
"Stevenson believes that in time governments will come under pressure to impose restrictions on processed food, much as they did to deter smoking. 'Demonstrating that processed foods can lead to subtle cognitive impairments that affect appetite and serve to promote overeating in otherwise healthy young people should be a worrying finding for everyone,' he said. The work is published in Royal Society Open Science.
"In the longer term, eating a western-style diet contributes to obesity and diabetes, both of which have been linked to declines in brain performance and the risk of developing dementia. 'The new thinking here is the realisation that a western-style diet may be generating initial and fairly subtle cognitive impairments, that undermine the control of appetite which gradually opens the way for all of these other effects down the track,' Stevenson said."
