Many people suffer from dilemmas about which one to buy and which one to avoid. So, it is necessary to know what to look for when buying oil. Nevertheless, all types of oils contain fat. But it doesn't mean that fat is always bad for health. Oils usually contain saturated, monounsaturated, and polyunsaturated fats, which are responsible for varying our blood cholesterol levels. Let's get to know the best cooking oils that are healthy for our bodies. Besides, we will also go through the worst cooking oil for our health. Basics about cooking oil Both refined and unrefined oils are commonly used in cooking. Most unrefined oils have low smoking points (the temperature at which the oil heats up and emits smoke), making them unsuitable for cooking at high temperatures. So this kind of oil should be used mainly for making salad dressings, marinades, and sauces or for low heat baking. Unrefined oil contains a lot of bioactive ingredients, which are beneficial for the body, as well as to add flavor to cooking. This type of oil is also better if the amount of vitamin E in it is unrefined as well as monounsaturated, such as olive oil, rice bran, canola, sesame oil, mustard oil.
