Attempts have been made to explain or justify some of the Halal aspect and haramprohibitions based on scientific reasoning as follows:

Carrion and dead animals are unfit for human consumption because the decaying process leads to the formation of chemicals which are harmful to humans.

Blood that is drained from the body contains harmful bacteria, products of metabolism, and toxins

Swine serves as a vector for pathogenic worms to enter the human body. Infections by Trchinella spiralis and taenia solium( Pork Tapeworm ) are not uncommon. Fatty acids, composition of pork fat have been mentioned as incompatible with human fat and biochemical systems

Intoxicants are considered harmful for the nervous system, affecting the census and human judgement leading to social and family problems and in many cases even death.
