What Is The Best Oil For Cooking?
Cooking Oils and Smoking Points are important factors when you choose to cook with oil. We have complied a comprehensive list for you to consider when you are looking for the different types of cooking oil and chart for your cooking and health needs. Discover what is the healthiest cooking oil for frying, what is the best cooking oil for your heart, and the types of cooking oils and their benefits and flavors.
It is important to know that not all fats are the same. The more refined an oil, the higher the smoke point. That’s because refining removes the impurities that can cause the oil to smoke. Did you know that a fat is no longer good for consumption after it has exceeded its smoke point and has begun to break down?
For health reasons it is also good to be aware of which oils contain healthy benefits and which are the worst cooking oils to use. Before reading the chart below, learn about the types of fat that are listed in the cooking oil chart.
Saturated fats are mainly animal fats and are solid at room temperature. These fats include butter, cheese, whole milk, ice cream, egg yolks, lard and fatty meats. Some plants fats are also high in saturated fats such as coconut oil and palm oils. By using the right oils and fats for the right reasons, you can preserve the healthful benefits. Your foods will not only taste their best, but also be healthy.
These fats can come from both animal and plant products. There are three (3) types:
Monounsaturated Fats – Usually come from seeds or nuts such as avocado, olive, peanut, and canola oils. These fats are liquid at room temperature.
Polyunsaturated Fats – Usually come from vegetables, seeds, or nuts such as corn, safflower, sunflower, soybean, cotton seed, and sesame seeds oils. These fats are liquid at room temperature.
Trans Fatty Acids – Trans fats are produced when liquid oil is made into a solid fat, such as shortening or margarine. This process is called hydrogenation.
Smoking Points of Fats and Oils:
Based on the above classification, the ideal cooking oil should contain higher amounts of monounsaturated and polyunsaturated fats, with a minimal or no saturated fats and trans fats. Different fats and oils have different uses. Each performs best within a certain range of temperature. Some are made for high heat cooking, while others have intense flavors that are best enjoyed by drizzling directly on food.
The smoke point of an oil or fat is the temperature at which it gives off smoke. The smoke point of oil depends to a very large extent on its purity and age at the time of measurement. A simple rule of thumb is that the lighter the color of the oil, the higher its smoke point. When frying, it is important to choose an oil with a very high smoking point. Most foods are fried between the temperatures of 350-450 degrees Fahrenheit so it is best to choose an oil with a smoking point above 400 degrees.

Re-using Cooking Oils
I, personally, never reuse cooking oils. The foods you cook the oils in will cause the oils to go rancid faster.
A recent study found that a toxin called 4-hydroxy-trans-2-nonenal (HNE) forms when such oils as canola, corn, soybean and sunflower oils are reheated. Consumption of foods containing HNE from cooking oils has been associated with increased risks of cardiovascular disease, stroke, Parkinson’?s disease, Alzheimer’s disease, Huntington’s disease, various liver disorders, and cancer. Once absorbed in the body, HNE reacts with DNA, RNA and proteins affecting basic cellular processes.
That being said:
Reusing cooking oil has been done for ages. There really isn’t a problem, if done properly. The greatest hazard is allowing the fat to become rancid (spoiled) and deteriorated to the point it produces undesirable flavors and odors. Besides ruining what would have been a perfectly good meal, rancid oils also contain free radicals that are potentially carcinogenic. Rancid oil has fewer antioxidants but is not poisonous.
To re-use oil safely, use these tips:
- Strain it through a few layers of cheesecloth to catch any food particles. Be careful with hot oil, though, because you can easily get burned.
- Shake off excess batter from food before frying it.
- Use a good thermometer to fry foods at 190°C.
- Turn off the heat after you are done cooking. Exposing oil to prolonged heat accelerates rancidity.
- Don’t mix different types of oil.
- Store oil in a cool, dark place.
- Avoid iron or copper pots or pans for frying oil that is to be reused. These metals also accelerate rancidity.
Signs of Deteriorated Oil:
- Oil darkens with use because the oil and food molecules burn when subjected to high/prolonged heat.
- The more you use an oil, the more slowly it will pour. Its viscosity changes because of changes to the oil’s molecular structure.
- Loose absorbent particles accumulate as sediment at the bottom of the storage container or are suspended in the oil.
- When smoke appears on the oils’ surface before the temperature reaches 190 degrees C (375 degrees F), your oil will no longer deep-fry effectively.
- If the oil has a rancid or “off” smell or if it smells like the foods you’ve cooked in it, it should be discarded.
