A new study shows that eating the right type of foods may reduce the risk for Alzheimer's disease.
In the new study, neurologists studied the diet of 2,000 people who were 65 or older for four years. They found that those eating a balanced diet had nearly a 40 percent lower risk of developing Alzheimer's than those who did not.
The healthy diet included foods high in vegetables, fish, fruit, nuts and poultry, but low on high fat foods, dairy products, red meat and butter.
"Our findings provide support for further exploration of food combination-based dietary behavior for the prevention of this important public health problem," said Dr. Nikolaos Scarmeas of Columbia University in New York and colleagues wrote.
Researchers also found that having a healthy heart may also be linked to a reduced risk of Alzheimer's.
"This may explain their apparent ability to reduce the risk of Alzheimer's, since heart disease increases the risk for Alzheimer's disease," said Dr. Samuel Gandy of Mount Sinai School of Medicine in New York .
"In any event, the diets do no harm and may have some benefits, hence their frequent recommendation by physicians," he wrote, noting that proof of which foods and the appropriate quantities have effects on disease risk remain to be clarified.
