When I was a kid, I used to love going to the local arcade and playing video games and redeeming skee ball tickets for prizes. For my first job at age 16 I figured the best possible job I could get would be at that very arcade. Some part of my innocence died when I had to open the machines to collect tokens and see how the coin mechanisms worked, as well as seeing the back room with huge bags of cheaply-manufactured prizes.
As I've delved deeper into biochemical minutiae I've gained a somewhat thorough understanding of many physiological mechanisms but I've lost the ability to view things as whole entities. I look at someone now I see probable pathologies and endocrine abnormalities instead of just a person. Surgeons and paramedics always creeped me out because they've spent so much time seeing disassembled humans that they couldn't help but be desensitized. A Ferrari stops being an amazing machine when you see one that's been in an accident.
I've seen the exploded diagrams, now how do I un-see them?
I took apart my first radio when I was 2 years old. It never stopped me from enjoying listening to it. I did my first autopsy when I was 20 years old. It never stopped me from looking at humans as "beings" nor stopped me from enjoying life.
Don't take yourself so seriously Travis. Usually and I don't mean this in an offensive way, people who start to look at everything in rational and logical ways, looking at people as homo sapien sapiens instead of human beings, have come to a point in life where they think they have something figured out. Typically that isn't the case, in fact it usually means you have nothing figured out or that you've missed the point.
Even though I know how a radio works and I know every bone and muscle and organ in the human body and what chemicals to use to highlight different pathology it still doesn't answer one basic question. Why?
You can observe anything work and figure out how it works using math, logic, etc., but it's always just observation. And even when you can predict every mechanism of a complex system you still don't know why. Everything we have to describe around us whether it be language or math, it's just a model, no matter how accurate.
Let the Why? be your constant source of perspective and I think you'll be fine. It takes some practice though to see how things work and still see the mystery. Look in the mirror and say I don't know anything, I don't know anything. As soon as you think you know something your wrong.
Study holistic health philosophy. Its a great way to remain grounded in the recognition that the whole is more than the sum of its parts.
It can be sort of hard in a society that tends to push reductionist thinking and reductionist treatment. I think the fact that you even pose the question speaks volumes to the fact that your not too far gone :)
Maybe try planning and cooking some fun meals with foodie-types. It won't erase your knowledge, but it will help you to see food from a social/pleasurable perspective. Alternatively, simply eating in a social setting will stop you from being so focused on your food and will also remind you that eating is not a purely biological process. A good meal should nourish the heart and soul as much as the belly!
This reminds me of myself when I used to make premature assumptions about people by their foods choices. It's easier to get along with others when you see them as a whole, rather than magnifying the little parts that make them... a person.
If I were you I'd ask yourself why part of you doesn't want to see people the way you say you want to. Part of you probably has a legitimate fear surrounding this issue -- but has adopted a less-than-ideal strategy to managing it.
I'd suggest therapy with a quality counselor, therapist, psychologist, etc. Personally I think that the Paleo community has largely ignored the mental health community at a great cost.
I struggle with this all the time. As much as I dislike nutritionism I see myself falling into its traps all the time. I think it's just something you have to work at. You can never unsee, but you can strive toward mindfulness and directing yourself to see the whole instead of the parts. Reading a little Michael Pollan never hurts either...
I have an idea - involve yourself into molecular gastronomy.
Other then switching obsessions, I don't think there is much you can do about it. Weed may help tho - you just don't care after...
Also, MMO games offer escape from that sht. Star Wars is out soon, you should try it. Warld of Warcraft is outdated.
To unsee it is not even a greatest problem - to unlearn, thats the problem.
