Preserve me not

My allergy incident has made me think a bit about preservatives. I'm probably not allergic to any preservatives, but I do occasionally think about the fact that I do fill up my body with a lot of junk. I have heard that people are taking longer to decompose these days because of all the preservatives that have built up in their body! Not sure if that's true, though.

I wonder if I could reduce preservatives in my diet and eat more non-processed food like fruit and vegetables, and all that good stuff. It might do my skin a bit of good, at least. Any thoughts, anyone? Do any of you try to live without preservatives and processed food?
