Halal and Kosher
The Kashruth is the food code prescribed to the Jews, being one of the main foundations of the Jewish Law, and culture.
Food in accordance with these laws are so-called kosher, "fit" or "suitable" for consumption. It is the equivalent of "Halal" in Islam.
Many people confuse Halal and Kosher and believe that they are equivalent.
There are indeed similarities and differences that Muslims or non-Muslims must understand.
