Read in Leviticus 11 and Deuteronomy 14 the list of birds, beasts, and fish God pronounced unfit for food. According to these chapters, clean fish must have both fins and scales. Scavenger birds are prohibited. Clean animals must divide, or split the hoof and also chew the cud. An example of an unclean animal is the pig.

“The pig is also unclean; although it has a split hoof, it does not chew the cud. You are not to eat their meat or touch their carcasses.”
—Deuteronomy 14:8.

Scientific research substantiates that God is indeed right in His warning against eating unclean meats. The health concerns are valid. Not only are there diseases in some animals but the effects of saturated fat on the human body is well documented. It is important to cook all red meat, poultry and fish at the recommended temperatures in order to kill the disease causing bacteria. God’s desire is for His people to live happy, healthy, and productive lives. Why? Because He cares about you.
