The Spanish have a reputation for wonderful, fresh food. Not surprisingly, at the heart of Spain’s long life expectancy is its adherence to the Mediterranean diet. Rich in fruits, vegetables, whole grains, olive oil, and fish, the diet has long been linked to reducing the risks of heart disease, stroke, and various chronic illnesses. It’s also associated with anti-inflammatory properties, which many experts believe is a key factor in preventing age-related diseases like Alzheimer’s and diabetes.
