5. Avoid processed foods
Skipping processed foods is one of the healthiest things about the paleo diet. However, most people tend to skip the details when shopping for paleo eats. So what does 'processed' mean? In simplest terms, if you've taken something raw (like a potato) and changed it using physical or chemical means (like making chips) then it's procssed. This means that anything packaged is probably a no-go.

Examples of processed foods includes refined sugars (like white and raw sugar), convenience foods (like frozen meals), bread, soft drinks, snack foods like chips, protein bars and biscuits, dairy products like cheese and butter, spreads and preserves, and, the kicker for most paleo eaters, preserved meats. This includes bacon, ham, salami and tuna.
