Healthy food may help you fight dementia and other cognitive problems as you age, according to a new study published Wednesday in the journal "Neurology."

Researchers surveyed nearly 30,000 patients and found those who had a diet high in fruits, vegetables and nuts and low in fried food and alcohol were 24 percent less likely to show the effects of an aging brain than those who had unhealthy diets.
