Types of Cooking Oils and How to Use Them
Types of Cooking Oil: Which Oils to Use & The Differences
How to Choose a Cooking Oil
First, you should stick to the guidelines your doctor gave you. Your body needs some fat, but fat is rich in calories (9 calories per gram), and some types of fat are healthier than others. It’s possible to get too much, even of the “good” fats. Your doctor, or a registered dietitian, can let you know what limits you should follow.
Also, know that each oil has a unique chemical makeup, so some will be more suited for sauteing, some for searing, and others for no-heat preparations, like salad dressings. When cooking, always keep in mind an oil’s smoke point — that’s the temperature at which the oil begins to smoke and produce dangerous fumes and free radicals. Generally, the more refined the oil, the higher the smoke point.
When an oil smokes or burns, any healthy fats and antioxidants burn along with it. The oil will also produce free radicals, which can be damaging and can cause health problems, especially if you use burned oil on a regular basis. Different cooking oils have their own smoke point temperature.
Types of Fats in Cooking Oils
Oil has healthy or unhealthy fats. Some oils have a mix of these fats, so get familiar with them to find the best option for you.
Saturated fats. These typically aren’t healthy. They’re mostly found in dairy products, fatty meats, or coconut and palm oils.
Trans fats. These are commonly found in processed food. Stay away from trans fats, or eat them sparingly. Check grocery labels to find out how much trans fats are in packaged food.
Monounsaturated fats. You can find these healthy fats in raw nuts, olives, and avocados. Monounsaturated fats can also be found in extra virgin olive oil, peanut oil, and avocado oil.
Polyunsaturated fats. These fats, which include omega-6 and omega-3s, are healthy fatty acids. You can get them from oily fish like salmon and mackerel, as well as chia seeds and walnuts. They’re especially good for your brain.
Types of Cooking Oils
You can find the most popular oils in most grocery stores.
Coconut oil. The buzz on this tasty, trendy oil is that it may have disease-preventing properties, but the blood pressure-conscious should beware: This oil packs the highest amount of saturated fat. It’s easy to be tempted by a great flavor boost, but too much saturated fat is a health no-no. Stick with traditional, nontropical vegetable oils. Olive and canola are better options.
Avocado oil. This oil has a sweet aroma and is quite healthy for you. It contains mainly monounsaturated fatty acids that can help lower inflammation. It also has a high smoke point, making it good for frying and searing.
Sunflower oil. This comes from sunflower seeds. It’s a refined oil high in omega-6 fatty acids. It’s good for your heart health and it can lower inflammation. It mainly has monounsaturated fats, and its smoke point is high. Look for its high-oleic versions to reap all the benefits.
Peanut oil. It’s heart-healthy and tastes neutral. Refined peanut oil has a medium-high smoke point and is commonly used for frying. You can find unrefined peanut oil, too, though it’s quite rare.
Other nut oils
Walnuts, pumpkins, pecans, and other nutty oils are showing up on fine dining menus and even grocery shelves. All of them have healthy fats for heart health benefits, including lowering blood pressure.
These are no-heat oils that aren’t great for cooking. Use them moderately in dressings.
Flaxseed and wheat germ oils are rich in omega-3 and omega-6, which may help lower blood pressure.These are also no-heat oils, making them good choices for salad dressings and dips. Just be sure to watch your portions.
Storing Cooking Oil
It’s best to buy cooking oils in amounts you’ll use within a month or two after opening them. Otherwise, they can go bad. If you’ve stored oil for a few months, check to see if the smell has changed.
Also, keep cooking oils in a cool and dark place, because heat and light can damage them.
