In the Bible, the Nation of Israel was given a Dietary Law by the Most High (what to eat and what not to eat). Thou shalt not eat any abominable thing. (Deut. 14:3)
There are certain beast, fish, birds, and insects that we are commanded by the Lord not to eat. There are clean animals that the Lord created that we can eat and there are unclean animals that the Lord created that we can not eat. (Lev. 11:1-47).

Animals which die by disease, old age, or killed by other animals are unclean and cannot be eaten (Lev. 17:15-16, Deut. 14:21)
All animals that are unclean and whose carcass (dead body) shall ye not touch meaning you cannot use any animals labeled unclean for things such as: boots, bags, rugs, furniture, food, decorations, clothing or any other personal use. (Lev. 11:8,11,13,20-31)
This society teaches that eating swine (pig, pork), shellfish (crab, shrimp, clams, lobster, etc) are delicacies and good food to eat. This is false. In fact, according to the Bible, they are unclean, and an abomination. (Lev. 10:10). Eating the wrong foods is what causes people to get sick and to be burdened with diseases at an early age. Why?
Because, they don follow the righteous Dietary laws in the Bible. And the Lord said, thus shall the children of Israel eat their defiled bread among the gentiles. (Eze. 4:13)
The chemicals, preservatives, and additives they put in foods today defile us and make us sick. The fast food restaurants (McDonalds, Burger King, Wendys, etc.) of today have no nutritional value for the human body at all. In fact, over a period of time they destroy the internal system of the human body. If any man defile the temple of the Most High him shall the Most High destroy, for the temple of the Lord is holy, which temple ye are. (1 Cor. 3:16-17)
The Bible teaches us about herbs. Herbs are natural medicines that the Lord created in the earth. And the Lord said, behold I have given every herb bearing seed, which is upon the face of all the earth, and every tree, in the which is the fruit of a tree yielding seed, to you it shall be for meat. (Gen. 1:29)
