If you could watch only Sergio Leone westerns like "A Fistful of Dollars," "Once Upon a Time in the West," "My Name is Nobody", that steady diet of machismo and mayhem might seem tasty at first. But eventually, it could leave you longing for something else to feed your imagination.

Well, the same is true of the typical Western diet, loaded with red meats, added sugars and syrups, and processed foods.

You may think it's what you enjoy, but it's a diet that's got nothing to feed your brain or body.

A new study published in the “Journal of the American College of Nutrition” looked at the relationship between the eating habits and development of Alzheimer’s disease among people in Brazil, Chile, Cuba, Egypt, India, Mongolia, Nigeria, the Republic of Korea, Sri Lanka and the United States.

It uncovered how mind-numbing the typical Western diet is.

In the U.S., one in nine people ages 65 and older has Alzheimer's disease. But the study found that switching to a traditional Mediterranean diet (olive oil, meats as side dishes and not every day, lots of fresh vegetables, fruits, and fish) cuts your risk of Alzheimer’s in half.

And traditional, meat-sparing diets in India, Japan, and Nigeria are associated with an additional 50 percent reduction in AD risk.

To protect your brain, eat 5 to 9 servings of produce daily; opt for 2 or 3 servings of fish (salmon is super) weekly; and eliminate red meats, added sugars and syrups, and processed grains from your diet.

That will chase Alzheimer’s disease off your plate.
