I've been eating Asian food for the last week or so. A small amount has been deep fried, most is flash fried in a wok with a small amount of oil, some is barbecued, some is steamed. Mainly pretty healthy, especially compared with the average UK diet. Also the time from picking or killing to preparation appears to be very brief.
They do eat more of the fat from the meat than we do, but the idea that fatty meat is unhealthy is another of those myths that could do with being retired.
