Diet and exercise are the fundamental keys to a healthy lifestyle. When it comes to aging, maintaining healthy habits can have positive long-lasting affects on your physical well being and your brain health. Moderate exercise performed regularly -- as opposed to intense or no exercise at all -- has been shown in studies to be linked to longevity and improved memory.

Making the right food choices can benefit more than just the number on the scale -- it can boost your overall brain health. Recent research has shown that women who consumed more “good” fats, such as the monounsaturated fats found in avocado, scored better on cognitive tests than those who consumed more “bad” fats, like the saturated fats found in red meat.

So where can you get your hands on these "good" fats? Check out our slideshow below for more foods to incorporate into your diet to give your brain a healthy boost.
