It makes sense to have more than one oil for cooking in your kitchen, but which ones are best for you? This infographic from Information Is Beautiful grades oils by their fat content, smoke point and flavour.
The oils are grouped by smoke point and the chart suggests uses for each group. It also shows each oil's percentage of saturated, polyunsaturated, and monounsaturated fats -- as well as trans fats when the oil is heated too high. Even though saturated fat isn't necessarily the devil we were taught it was, you might prefer to choose oils that have bigger green bars (monounsaturated fats) and a good ratio of Omega-3 compared to Omega-6 fats.
The graphic points out other considerations and notes, such as the more bold the colour of the oil name, the stronger the flavour. You can see all the source data for this infographic in this Google spreadsheet.
