The Chinese who use lots of oil are not healthy. The poor Chinese who live in the city and are consuming Chinese fast food and the wealthy ones too are having the same health issues as those in the West. When I was there last year you can see many overweight Chinese now (this is a worldwide problem). But if you go to the provinces you see lots of healthy people.

It is the same where I live in Thailand. The Thais in Bangkok now have KFC and McDonalds and their health is suffering. But if you go up country where they eat fresh vegetables and fish all grilled or raw, they are much healthier. And remember, it does not matter what oil you use if you cook with it. Coconut oil and Olive oil are great until you heat it for frying. At that point, all oil becomes toxic and cancer causing. So use as little as you can for the best health benefits from eating your food and do not heat for long and definitely no deep frying. NO no no. Hopefully this helps.
