There is nothing wrong with it per say, but it is not suited to all sorts of cooking.
1. It has a lower smoking point than other cooking oils meaning that it is not suited to high temperature cooking.
2. It has a distinctive flavour which you may not want to impart on some dishes.
3. It is not cost effective in some cooking. Imagine the cost of deep frying in good extra virgin.

i see. yeah i knew about number2 and 3. when we need to deep fry we just go get a bottle of canola oil.
i thought there was some health hazard i was unaware of .
thanks!
