Holy Quran has mentioned PIg as " Najass "
When you talk about " Najass " than the debate of Health won't come in between the argument. Question can be raised, Why ?
Because when you raise the points of Health than there are many other animals which are not haraam (not prohibited from eating) so you will be struck in this dilemma than the Fat of X animal cannot be eaten because it can create Cardiac issues. Furthermore this can be said aswell that what is than the downside of eating lean meat of Pig if there is no fats in it than what are ill effects of eating it ?
This is why this argument of Health related disadvantages is just a waste of time, there are nothing significant in these debates.
Holy Quran has called it " Najass "
Najass means that some of the habits of Pig are filthy. And this prohibition is a protest against those habits.
Two such things which are present in this Animal is that :
1. Amongst animals, you would find homosexuality orientation most in this animal Pig.
2. If the need arises it eats its own young ones aswell. Although Carnivorous animals do not do this. When Pigs young ones die it even eats them.
These two habbits of Pigs are so Impious & putrid that Islam has prohibited this.
Once in University of London there was a Coffee break and all the classfellows were discuss this when a Muslim Student gave this explanation. A girl stood up and said :
What is the bad effect of homosexuality ?
The Muslim boy said that you proved my point right that those who eat Pork do not see ill-effects of homosexuality, so this is the reason that it is Prohibited

hehe
Today in World this debate is ongoing. People say that what if somebody is a homosexual you can even become Minister of religion while being homosexual.
There is even a bigger Finesse in this Prohibition, that is Allah is the Creator and He has taught us that without my permission you cannot kill any animal. Every Animal has its Incest. This is why we say Bismillah, Allah o Akbar before slaughtering an animal to say that we are doing this after permission of Allah SWT otherwise from myside I do not have the right to kill any living organism. This is why it is only permitted to kill those worms which can harm humans (self defense). This is why Islam does not permit killing those animals which are not for Eating.
So this is principle of Islam that Life is the property of Allah and without Allah's permission you cannot take blood of any animals (cannot kill).
Now if Allah Prohibits that you cannot eat an animal, so Allah is the Master, Owner, Lord and so if we eat Pork than all things we eat will be of forced as it won't be through permission of Allah just like even if you don't have a right to something you steal it.
And if and where Allah stops you from something and you stop than the other eatables become halaal (allowed) aswell because they are under permission.
So the Main question is that whether Creator (Allah) has the right or not ? So if we accept that He is the Creator and the Owner that if He says don't eat this than what is the right of us to question HIM that prove us that why we should not eat this ?
This One Prohibition has taught Us a golden principle that whatever we do we do it with Allah's permission and where there is no permission we should stop there.
When you tell people all this than you will know that mostly this question is asked as a result of Atheism. Because in Atheism there is no Concept of God, no concept of Belief. They think that we do not eat it because of suspicion and if we are not taught scientifically that why we shouldn't stop eating it we won't stop.
While we Muslims have a totally different Point of View of stopping here there is no debate of Science.
Even if Today I am able to tell something Scientifically than why for 1500 years Muslims stopped themselves from eating Pork ? So whether Science is in favour or against it is good for debate but A Muslim will stop himself from doing this because of Allah's order.
Most importantly this prohibition is also for those who are consuming Pork. One more counter question one should ask is that in this Islam came at Number 3. First Judaism prohibited it and Prophet Jesus AS did not declare it Halal. Show Us where He AS declared it Halal ? So first you tell that why in Judaism it was prohibited ? Prove it with wisdom than we will see whether there is a logic or not.
We the Muslims stop ourselves because God told us to do so, So if you want to stop from eating that first tell Us the Philosophy of Judaism and tell that with Jesus AS not permitting it why you declared a prohibited thing as allowed ? What was the Authority with You ?
