Not at all.
My father had a PhD in food science and taught me a lot about preservatives, how food is processed and all of the additives and chemical treatments food goes through before making to the shelves of grocery stores. Knowing all this, you would think I would eat a lot more organic food now that it is more readily available.
I don't, because processed food tastes better to me. The way I see it, a person dies of something and there is no way of predicting what will kill you. If it pleases the senses, I will typically consume it. And don't bother with the arguments like "you are what you eat", "your body is a temple", "healthy living is clean living" and all that other stuff. If that works for you, I'm happy for you and don't change a thing.
In the end, we are all still worm or fish food and they will eat us no matter what crap we put in our bodies :)
