cooking with oil and heart health
I use vegetable oil for stir frying. I know that plant oils (except for coconut and palm ) are good for your heart, but what happens when you heat them? Which ones are suitable for frying and which aren't in health terms? What are the risks?

Thank you.

Dear Mia
I apologise for only answering your question today, but I had to have an operation last Wednesday, and although I informed the boffins who administer the Message Board, they failed to block incoming messages while I was in hospital.
All plant oils, including red palm oil (see the DietDoc Topic on 10 January 2005), are good for the heart to varying degrees. Heating these oils ONCE will not cause problems, but if you should store the used oil and repeatedly use it at high temperatures, then the fatty acids may break down and form so-called trans-fatty acids which are extremely harmful to health and the heart. So only use your oil at high temps Once. Red palm oil and avocado oil have the highest smoke points of all the oils, so they are more resistant to breaking down.
Best regards
