Surprising foods to eat and not to eat!

We all know the foods to eat and not to eat, right? Like full fat crackers, chips, soda and highly processed foods with no fiber. They add empty calories that do not add any nutritional benefit.
But what about the foods that you should only enjoy in moderation? Like nuts and avocados! While extremely healthy, they are also very high in fat overall, so portion control is critical. And a surprising food you can eat (in moderation too of course!) is dark chocolate squares. I recommend the individually packaged, less than 1 oz. per piece net weight varieties (such as Ghirardelli 60% dark squares). Dark chocolate is a good source of flavonols and rich in antioxidants.
