Whether you are cooking or baking, subbing canola oil for butter will save you 6 grams of saturated fat per tablespoon. One tablespoon of butter contains 7 grams of saturated fat, while the same amount of canola oil delivers just 1 gram. And 1 tablespoon of olive oil has 2 grams.
Overall, an easy way to guide your oil choice is to look for one that's liquid at room temperature. That means it’s mostly made of healthy unsaturated fats; solid ones, such as coconut oil and palm oil, are mostly saturated fat.
