(23-11-08) What You Eat Could Raise Your Risk of Alzheimer's

Eating the wrong diet could increase your risk of developing Alzheimer's disease. Scientists have found a link between the degenerative brain disease and raised levels of an omega-6 fatty acid.

Researchers compared the brains of mice bred with a condition that mimics Alzheimer's to those of normal mice. They found higher levels of the omega-6 fat called arachidonic acid in mice with memory loss and confused behavior.

The researchers believe that the substance interferes with the brain's nerve cells, causing over-stimulation, and that lowering levels would allow the cells to function normally.
