"Brain Damage," Olivia Judson, The New York Times, April 20, 2010:

Whatever the causes, the implications are grave. In the United States today, around one-third of adults are obese. At the same time, dementia is already one of the most costly and devastating health problems of old age. The possibility that obesity today will lead to higher rates of dementia in the future is, therefore, deeply alarming.

The obvious question is: can obesity-associated brain damage be reversed? No one knows the answer, but I am hopeful that it can. Those two old friends, a healthful diet and plenty of exercise, have repeatedly been shown to protect the brain. Foods like oily fishes and blueberries have been shown to stimulate the growth of new neurons, for example. Moreover, one study found that dieting reversed some of the changes to brain structure found among the obese. Which suggests an interesting study. The most effective — and radical — treatment for obesity is bariatric surgery, whereby the stomach is made much smaller or bypassed altogether. Do people who have taken this option show a reversal, or at least a slowing, of brain atrophy?

Just ordered Chinese. That will help my brain, I suppose.
