Preference....it is all driven by preference and nothing else. No religious, tribal taboo, new age, old age, nothing but personal preference. For a long time I wouldn't date a woman that had an heavy red meat diet. Ever wonder why the French drink so much anise based drink? It attempts to mask the odor emitted by the skin. That's what I hear anyway. Bottom line is there is no mystical approach with my diet just what I like. Remember I don't smoke tobacco products nor drink anything with alcohol either. My weakness is pasta!!
