You might remember the saying, "An apple a day keeps the doctor away."

But have you heard that by eating nuts you will be keeping the doctor away and adding years to your life?

A longitudinal study conducted by the Universitat Rovira I Virgili in Spain gathered more than 7,000 people over the age of 50 to test the nut-longevity connection. The researchers found that those in the study who ate nuts more than three times a week had reduced their risk of cancer and cardiovascular disease compared to those in the study who did not eat any nuts.

In general, nuts have many powerful health benefits (that is, nuts that are raw and dry roasted, not smothered in salt). Nuts are a great source of unsaturated fatty acids, which can help lower your LDL (bad) cholesterol. Nuts also contain omega-3 fatty acids, fiber and protein.

Instead of grabbing something out of the vending machine at work or reaching for those potato chips in your pantry, try eating a handful of mixed nuts. It may take a little will power, especially when that 2:00 p.m. lethargy is making you crave something sweet. However, your future self will thank you for it.
