Grapeseed oil
I'm a regular health magazine reader and try and stay up to date with current nutritional research. Profits of the benefits of olive oil are aplenty, but I heard from a questionable source that when olive oil's temperature exeeds 100 degrees celsius, it can become just as detremental to your health as sunflower oil. The same person advised me to rather use grapeseed oil because it's chemical makeup is not altered by high temperature. Is this true and if not what is the best cooking oil to use? This month's Men's Health lists a range of healthy oils (sans Grapeseed oil), but mention nothing of the affect of heat on the oils...

Dear Dahli
All oils will change chemically if heated to high temperatures and if heated repeatedly. It all depends on the composition of the actual oil. You can use olive oil, grapeseed oil, avocado oil, etc, just don't reuse them once they have been heated up to avoid any trans-fats that may be formed at high temperatures.
