As it turns out, the newest health-food trend is actually the oldest. With roots that stem all the way back to the Paleolithic Era, the mantra of the Paleo diet is: If a Caveman couldn’t eat it, neither can you.

Essentially, what that means is that processed food and sugar are out and fresh produce and animal products are in. If you’re interested in learning more about what Paleos can eat, here’s a quick rundown:

WHAT TO EAT:

• Lean meats, fish, seafood and eggs
• Lots of fresh fruits and veggies
• Starchy vegetables like yams and sweet potatoes
• Nuts and seeds (excluding peanuts)
• Avocado, coconut, olive or other “natural” oils

If you or your family is considering a Paleo lifestyle, know that there’s no better way to cook a primarily meat-based diet than on the grill. Though Cavemen might not have had the advantage of SABER’s proprietary infrared cooking system, don’t let that stop you from enjoying meats and vegetables that are juicy and full of flavor.

When grilling the Paleo way, just make sure to steer clear of real butter and, of course, store-bought marinades that often contain a mind-boggling amount of refined sugar. With recipes that use dates, honey and even peaches as natural sweeteners, your kids, friends and family won’t even notice you’ve gone Paleo. For dessert? Whip up some honey-grilled watermelon to sneak in an extra serving of fruit for the kids.

Even without refined sugar, it looks like barbecue season just got a whole lot sweeter.
