Dear Fried Foods
The change in kJ content caused by frying a food in oil or fat depends on a number of factors such as the consistency of the food (the kJ content of foods that absorb oil or fat will increase to a greater extent than foods which do not absorb oil, e.g. fish on its own vs fish dipped in breadcrumbs), the cooking temperature and length of the cooking period. To illustrate here are the kJ values of fat-trimmed beef per 100g: a) Braised 908 kJ; b) grilled 855 kJ; c) beef stew with vegetables - 500 kJ. In regard to fish: 1) White fish like hake crumbed and fried in sunflower oil: 869 kJ per 100g; 2) White fish like hake grilled 462 kJ per 100g.
