LEV100 Do not eat forbidden animals and beasts. All foods that Hashem forbids His nation are in some way harmful to their bodies. The body is the tool of the soul, because by virtue of the body that clothes it, the soul can act and be elevated by good deeds. Therefore, Hashem distances us from harmful foods. Thereby, our souls can act in the correct way, without hindrances from the body’s crass nature and a blocked up heart.
