I guess as humans we just tend to tag stuff, name it, describe it. We are addicted to it. And so since natural foods are "healthier" than processed or chemically loaded stuff, we classify or tag it as "healthy". Of course this doesn't fit for everyone. Everyone is different, and many people have health conditions that make some foods bad for them, a.k.a. unhealthy! Maybe abusing some of the already unhealthy stuff is what causes some of these conditions? Moderation is key, and definitely listening to our bodies. This is not an easy thing though. There's so many factors and variables involved.
