9 cooking mistakes that can make your food more toxic

Cook with olive oil, but only for certain foods. So, what are the healthiest fats for cooking? Dietitian Maggie Michalczyk recommends doing your homework before buying a jumbo jug of one particular oil and using it for everything. “These oils have different smoke points – that’s the temperature at which they begin to burn – and once they start smoking, the fat breaks down and they can release harmful free radicals into the air,” she says. Be sure to keep portions of oils in check when cooking. This will prevent additional kilojoules (most serving sizes are two tablespoons).
