In Islam, we are forbidden to eat pork. However, if there is NOTHING else to eat, and a little swine is walking by, Muslims may kill and eat the pig as a means of sustaining life, but as soon as other foods are available we must stop eating the pig and go back to our regular diet.
Concerning WHY people should not eat Pig. . . Pigs have one of the fastest digestive systems. . 4 hours from mouth to evacuation. They eat filth and dead meat and even their own dung. The digestive system does not have time to clean out most of the impurities and poisons, so these substances get imbedded in their fat cells, and are stored there. Even trimming the fat off the meat does not get rid of the toxins, since 25% of pigs fat is IMBEDDED INSIDE the meat itself, in very small cell pockets, so you cannot remove the fat, and will be consuming these toxins as part of your meal. Compare to a cow, or other cud-chewing creatures (herbivoes, including rabbits) that have slower digestive systems (as long as 24 hours) do NOT eat dead meat or offal, and do not have fat cells imbedded inside the meat itself, and you can see why Pork is such an indesirable meat to eat.
Add in Trichinosis, the rapid decay of pork, and it's history of being an animal where viruses such as Swine flu develop, and there is little GOOD reason to eat pork.
Want a REALLY good reason to not eat pork?? Stand downwind of a fast food restaurant (MacDonalds) while they are cooking breakfast sausage. . . it smells like a sewer!!! Absolutely disgusting. . and you want to eat THAT?
Be my guest. Allah said NO. . .I think I'll listen.
