Frugality and Abstinence of the Patriarchs

Description
The frugal diet of the antediluvian patriarchs — eating only herbs and fruits, abstaining from meat and wine — contributing to their extraordinary longevity

The frugal diet of the antediluvian patriarchs. The more common opinion of the Fathers and Doctors is that men up to the flood ate herbs and fruits, abstaining from meat and wine from religious scruple, not by precept. This frugality contributed to their extraordinary lifespan of 900 years.
