There's a reason why pork is popular eating in many countries,
that's because pigs are the most efficent at converting feed to
meat, about 25 percent of feed in fact. For poorer communities,
rearing pigs is the most penny wise for lifestock.
As for the supposed "ill" effects of eating pork and all the
supposed "toxins" and such. There has been I repeat, NO conclusive
scientific research done into pork that has proven any of this. And
the supposed list of diseases you can get via eating pork is
misleading, for the risk of catching ill effects from other meats
or even vegetables are also present. Though of course, common sense
is encouraged in eating pork, avoid the lard if you can and don't
overload on it, because it's has the highest energy content of all
the meats you can eat. Eating pork is like eating about any other
meat. Though personally I'm a chicken and lamb person.
Other then that, trying to find scientific reasons not to eat pork
to justify religion is pretty much lik trying to get a square peg
into a round hole. Most of the scientific "reasons" put up dun hold
water when put to critical scientific method. The reasons appears,
are for other then actual metaphysical reasons.
