Then there's me. My dietary rule (I only have one) is "if it tastes good, eat it." I have no idea what's in what I eat, nor do I care. Thankfully most of the things I like are reasonably healthy, and I always eat/drink in moderation. I enjoy one....just one...adult beverage, usually a beer, with my evening meal. I rarely eat any fried foods, don't over-do the red meat thing, and we tend to reserve big desserts for special occasions. My splurge is Coke Zero. I'll have at least 3 a day (because there are 3 parts to a day....morning, noon, and night). To me preservatives are meant to preserve you, as in "keep you from going bad". Somehow, this all makes perfect sense in my warped mind. Yep, life is good.
Now if you'll excuse me I must go have my breakfast brownie. :)
