Zabihah Halal: quickly slaughtered by human hand at the throat, not by machines 

Halal (permissible): the name of The(al) God(ilah) - "Allah"(in arabic) that gave it life in the first place is mentioned

*Pork Is In More Than Just Meat* (look for [K]osher or U symbol on packaging) 

Gelatin, Glycerin, Enzymes (microbial are halal), Mono Diglycerides

Fish don't retain flowing blood after death, making them halal

Men, beware of soy! (with female hormone estrogen)
