The Bible tells us the three most righteous men were Job, Daniel, and Noah (Ezekiel 14:14). Righteous means right living, and interestingly all three are mentioned in regards to diet.
Job enjoyed a good carnivorous diet.
Job 1
1 There was a man in the land of Uz, whose name was Job; and that man was perfect and upright, and one that feared God, and eschewed evil.
2 And there were born unto him seven sons and three daughters.
3 His substance also was seven thousand sheep, and three thousand camels, and five hundred yoke of oxen, and five hundred she asses, and a very great household; so that this man was the greatest of all the men of the east.
4 And his sons went and feasted in their houses, every one his day; and sent and called for their three sisters to eat and to drink with them.
Daniel of course is famous for his 21 day water and vegetarian flush, and Noah was a practitioner of fermentation, (Genesis 9).
