...snip...We have to go in more technicalities to understand why pig are not allowed to eat in relation to the zonal considerations of that area. It may be on hygeine ground, its effect on their followers or just an respect to any animal unabling people to save them. Whatever is there, but we need not to relate sin with any social & spritual concept but we should just see the effect of any act on us. If it is a bad effect directly or indirectly then it is a sin & if it is good effect it is opposite to sin. In more scientific way we can just think off that any act which deviate us from our "homeostatis" state is a sin & which bring us towords this is an "antomyns to sin"....snip...
Again, sins and taboos are closely related. Eventually some of those related to dietary prescriptions may have started after empirical observations that some health problems are more commom among people who eat a certain type of food.
Once again, if your proposal were true, people living in similar environments would have developed the same dietary restrictions, and since a clean body is a clean body everywhere, the prescriptions would be the same. Note that people living very close, but with different cultures, have different restrictions.
Besides, there are a lot of other problems, that show that most of the dietary restrictions must have another origin. Here’s a few-
Fishes, shrimps, crabs, lobsters are taken as being healthier than read meat. So, why lobsters, shrimps and fishes without scales are considerd impure by jews?
So, if the problem is related to meat consumption, why some religions do not allow jains do not eat root vegetables such as onions, carrots and potatoes (Aren’t the jains among those subjected to such restrictions? I think so, but I may be wrong). They are quite healthy and would not have the restriction (foolish, IMHO) that a life was not taken to provide us with food!

...snip...Furthur pls differanciate between true/natural sins, religious sins, social sins etc. ...snip...
So, you are separating in to classes of sins. Fine. “Social sins, religious sins”, so, with this you just agreed that sins and taboos are concepts related to culture. And there isn’t such a thing as a “true”or “natural” sin, because the concept is related to culture.

...snip...No, I have mentioned any act, not just eating habbits....snip...
There are a lot if problems when you consider a sin as na act that causes problem to our body. Its na unacepptable generalization when viewed under a broad angle. Kumar, I am sorry, but you seem to be making a (dangerous) generalization based on your cultural background. Dangerous because it assumes that your cultural background is the right one!
So, for example, what does the following have to do with health?
Why was wearing clothes made of two fabrics forbidden to ancient hebrews?
Sex it is a healthy act. How can it harm us? Why having sex is considered a sin if not for reproduction? Why some cultures are extremely repressive in this issue while other quite liberal? Were the cultures in which sex was a part of their religious rites sinful?
Take incest, for example. If one uses the judaic, christian (and I belive also the islamic) notion of incest. Many of the unions among the royal families in ancient egyptians (not to mention other areas) would then be considered incestuous. Were the ancient egytians a nation of sinners?
To kill is a sin. But stoning adulterous people is healthy?
And please note that the notions of sin change with culture and time.
[edited to add] I say you should make a new thread about this on the religion forum [end edit]
