It may sound extreme but it is not without merit. If the oil begins to smoke, it means that it begins to break down. This generates substances called free radicals (right YT?) that are bad news healthwise (ageing and cancer-causing agents). These are the reason behind doctors' admonishing against eating fried anything. I do like several fried dishes myself and applying the 'quick seal' on meats initially is a must for most Greek meat dishes. However, there is no denying that there is a tradeoff between good taste and good health. That's why what Petey does is not as far fetched as it may sound at first. He is obviously a strict practicioner of the 'better safe than sorry' principle.
