Researchers in Spain reveal that a Mediterranean Diet can improve brain function.

This is a study of over 400 people in Barcelona, Spain. The 55 to 80 year-old volunteers had an average age of 67.

Two study groups were assign a Mediterranean Diet with either 1 liter extra virgin olive oil per week (about 5 tablespoons per day) or 30 grams mixed nuts per day.
