While the area I live in may have made my exposure to this fruit a little slower than it was for most people, it's still a relatively new addition to the regular fruits and veggies on grocery store shelves. In a short span of time the bizarre-looking pomegranate has moved from exotic to mainstream.

The world of nutrition has its trends just like anything else, and pomegranates certainly had their day (or couple of years) in the sun. Pomegranates have been linked to health benefits for erectile dysfunction, cancer risk reduction, lung health, and other issues. And they certainly are good for you... not to mention tasty. (Though pomegranate juice can negatively interact with certain medications (such as some blood pressure meds), so check with your doctor.)

But when a food item becomes trendy, there is a bit of a halo effect; anything that has that item listed on the package automatically seems healthier and better for you. Health by association, if you will.

Healthy eating is important for everyone -- it helps you maintain an appropriate weight, provides your body with the right mix of vitamins and minerals, and sustains energy. But healthy eating has another perk ... it helps promote male fertility.

Male infertility is the cause of roughly half of all infertility cases. And erectile dysfunction can affect a couple's sex life and strain a relationship. To maintain or improve sexual function and fertility, a heart-healthy diet is imperative. Healthy blood pressure and unclogged arteries equal an improved blood flow -- and when it comes to men, improved blood flow equals healthier sexual function.
