Exercise Diet and Dementia

A presentation at the Alzheimer's Association International Conference at Honolulu, suggest that physical activity, tea, Vitamin D and Walnuts may reduce dementia risk in older adults.

Long term studies, according to the presentation, have shown that people who routinely perform moderate to heavy levels of physical activity had about a 40% lower risk of developing any type of dementia. Those reporting the lowest levels of physical activity were 45% more likely to develop any type of dementia.

The presentation also reported that people who consume tea at a variety of levels had significantly less cognitive decline by 17 to 37%.

It was also reported that "the odds of cognitive impairment were about 42% higher in those who were deficient in vitamin D, and 394% higher in people who were severely deficient."

Studies with mice have shown that there may be a protective effect of walnuts on cognitive abilities. Alzheimer's mice on a 6 to 9% walnut diet showed significant improvement in learning, memory and motor coordination.
