How much cooking oil is healthy?

According to the Balanced Diet Pagoda of China Residents published by China Nutrition Society, the recommended amount of edible oil per person per day is 25g when the diet is not too greasy. At present, most of us eat 40 to 50 grams, which is seriously exceeding the standard. It may not be easy to drop to 25 grams. What we can do is to use as little oil as possible.
