'Diet' in the Bible

John had clothing made of camel's hair and wore a leather belt around his waist. His diet consisted of grasshoppers and wild honey.

John was clothed with camel’s hair and wore a leather belt around his waist, and his diet was locusts and wild honey.

Do not be carried away by diverse and strange teachings; for it is good for the heart to be established and strengthened by grace and not by foods [rules of diet and ritualistic meals], which bring no benefit or spiritual growth to those who observe them.
