Trans Fats-Brain Damage Link Suggested By New Study On Nutrient Levels
It seems like there's a new study relating nutrition and brain development every week. Sometimes, health experts tell us to eat grilled tuna, high in omega-3s, to ward off Alzheimer's disease - and then, a new report on mercury levels reveals just how risky tuna can be for brain health. Clinical studies that have tried to administer certain nutrients to promote better neurological health have almost always failed. The haziness of all this data makes it hard to place your faith in any one diet.
Oregon State Health University's Dr. Gene Bowman has a theory about the source of the confusion. He thinks that the reason past studies have failed to produce satisfactory results is that they're getting their information from the wrong place. Most studies on long-term nutrition and health rely on dietary surveys, which ask studies' participants to remember everything they've eaten over the past few weeks. That's a tall order when you're talking to people at risk for - or even in the early stages of - dementia.
"People with advanced age have more problems remembering what they've eaten," Bowman told The Huffington Post.
But Bowman thinks he has a better way to do things. Instead of asking people what they've eaten over the past few weeks, he looks at nutrient levels in their blood and finds out for himself.
It's not 100 percent foolproof, and it works better for some nutrients than others, but Bowman has published several studies that have demonstrated that blood levels of many nutrients are well correlated with a subject's diet over a period of about a year. ...
