Ran 4km and gym workout this morning.

Olive oil facts (extracted)
Excessively heating olive oil will evaporate the alcohols and esters which make up its delicate taste and fragrance. Heating olive oil will not change its health aspects, only the flavor. Use a cheaper olive oil which doesn't have much flavor to begin with if you want to fry with it, add a more flavorful olive oil after cooking or at the table.
Heating food will break down its nutritional value. High heat such as frying is worse than moderate heat such as steaming, which is worse than eating vegetables raw. It is not the cooking oil per se, but the high heat of frying. I am not aware of any edible cooking oil which of itself diminishes the nutritional value of the food cooked in it. Most nutritionists recommend lightly steaming vegetables or eating them raw. A touch of a flavorsome olive oil added at the table will add taste and healthful anti-oxidants. Such is the "Mediterranean diet" which has been shown to help prevent coronary disease and have other health benefits.
