that was really great information about oils being referenced in the bible.
even if you are vegetarian, nuts and seeds which include oils in their unprocessed form are part of a healthy balanced diet.
the brain, nervous system, cell wall for every cell in your body, liver, colon, lungs, and probably every organ needs a certain amount of fats/oils to remain healthy.
for people who are very ill it is ok to abstain for a while to give the body a rest, but prolonged avoidance will lead to other possibly worse problems.
