Refined oil, on the other hand, typically has a higher smoke point, which is generally about degrees Fahrenheit. Although refined varieties of the oil do have a relatively high smoke point, they may not be the best choice for high-heat cooking. This is because they are high in unsaturated fatty acids, which are more susceptible to oxidation when exposed to heat.
This leads to the buildup of harmful free radicals in the body and an increase in oxidative stress, which can have detrimental effects on several aspects of health. Oxidative stress can trigger inflammation and contribute to a number of chronic health issues, including cancer, heart disease, rheumatoid arthritis and neurological conditions.
This common cooking oil is also high in omega-6 fatty acids, which can increase levels of inflammation in the body. Sustaining high levels of inflammation can also be harmful to health and could increase the risk of chronic disease. Another common question is: Is peanut oil keto? And keto or not, it should also be paired with a variety of other healthy fats as part of a well-rounded diet, such as olive oil, coconut oil or avocados.
Additionally, while refined peanut oil is considered non-allergenic, unrefined peanut oil can trigger food allergy symptoms in those with an allergy to peanuts and should be avoided. While refined varieties are considered safe for those with a peanut oil allergy, unrefined types are not. If left unopened, most types can stay fresh for up to one to two years. Another common question is: Can you reuse peanut oil after frying?
Additionally, keep in mind that the oil does break down with each use, so reusing it multiple times can cause the quality to quickly deteriorate. Finally, although this oil is associated with several health benefits, it also oxidizes easily and is high in pro-inflammatory omega-6 fatty acids. Olive oil is one of the most well-known and popular oils available, and it is often considered one of the healthiest oils to cook with.
Both are low in saturated fat and high in unsaturated fatty acids. Additionally, extra-virgin olive oil and unrefined peanut oil also have a similar smoke point of around degrees Fahrenheit. The main difference between peanut oil vs. Coconut oil is a great alternative for a high-heat cooking oil. It has a high smoke point and is rich in medium-chain triglycerides, which are a beneficial type of fatty acid.
Avocado oil is another healthy option for a peanut oil substitute. Vegetable oils generally have a comparable nutrition profile, with high amounts of pro-inflammatory omega-6 fatty acids, lots of unsaturated fats and minimal saturated fat in each serving. If you do decide to give it a try, be sure to select unrefined, cold-pressed varieties whenever possible to maximize the nutritional value.
For a few ideas of how to make peanut oil part of your meal plan, check out these simple recipes to get started:. Summing it up, Lichtenstein, who served on the AHA's panel, said that coconut oil does not have any unique heart-health benefits, and its " halo effect " — meaning its perception by the public as a healthful food — is probably not justified from a scientific perspective.
There is not any reason to use coconut oil rather than unsaturated oils, and there are potentially disadvantages from its high content of saturated fat, she said. This versatile cooking oil is extracted from grape seeds left over from wine making, according to the Academy of Nutrition and Dietetics. A favorite of chefs and foodies, grapeseed oil has a mild flavor that can be combined with other, stronger flavors.
Store grapeseed oil in the refrigerator to prevent it from becoming rancid, food experts say. Grapeseed oil has a high percentage of polyunsaturated fat 71 percent polyunsaturated, 17 percent monounsaturated, 12 percent saturated , with a similar fatty acid profile to soybean oil 61 percent polyunsaturated fat, 24 percent monounsaturated, 15 percent saturated , Lichtenstein said. According to a review of studies published in the journal Nutrition and Metabolic Insights, little is known about the effects of grapeseed oil on human health.
Few studies have looked at the heart-health benefits of this mostly polyunsaturated fat. Because of its prominent role in the Mediterranean diet , olive oil is a popular cooking oil. Extra-virgin olive oil comes from the first pressing of the olives. This results in an oil that has more flavor and a fruity aroma, and is less processed, meaning it is considered "unrefined. Refined versions of olive oil, called "pure," are lighter in color and milder in flavor than extra-virgin oils.
Olive oils typically have the highest percentage of monounsaturated fats among cooking oils although some high-oleic versions of other oils may have artificially boosted levels of monounsaturated fats. Olive oil is also rich in antioxidants called polyphenols , beneficial plant compounds that some evidence suggests may improve heart health. A study done in Spain of about 7, men and women at high risk of heart disease found that people who were advised to consume a Mediterranean-diet supplemented with extra-virgin olive oil or mixed nuts had a lower rate of heart attack, stroke and death from heart-related causes, compared with people who were advised only to follow a generally low-fat diet.
From a heart-health standpoint, there is no real significant difference between extra-virgin olive oil and other kinds of olive oil, Carson told Live Science. There are better choices than extra-virgin olive oil for cooking at high temperatures, such as when frying, because the oil cannot withstand very high heat before it starts to burn and smoke, Carson said.
Refined, or pure, olive oil may be more suited for high-temperature cooking. Among cooking oils, peanut oil has the highest monounsaturated fat content — about half 49 percent. Peanut oil has a similar percentage of polyunsaturated fat 33 percent to canola oil, another mostly monounsaturated fat. Its percentage of saturated fat 18 percent is higher than that of other vegetable oils, but not to the point that it's a concern for heart health , and it still has less saturated fat than coconut or palm oils, Lichtenstein said.
A flavorful oil with a pale color and nutty aroma, peanut oil can withstand high heat and is a good choice for cooking Asian-inspired meals and stir-fries, according to food experts. Often used in Asian, Indian and Middle Eastern cooking, sesame oil is a good mix of polyunsaturated fat 46 percent and monounsaturated fat 40 percent , Lichtenstein said.
The remaining 14 percent is saturated fat. It's not usually used as a cooking fat and is used more for its intense flavoring, she noted. Sesame oil lends a nutty flavor to any dish, especially toasted sesame oil, which has a darker color and bolder flavor. Refrigerate sesame oil after opening it.
Light in color and neutral in flavor, sunflower oil has one of the highest concentrations of polyunsaturated fat 69 percent among cooking oils. It supplies some monounsaturated fat 20 percent and is low in saturated fat 11 percent , making it an overall heart-healthy option.
Sunflower oil is a good all-purpose oil because it can withstand high cooking temperatures. Shoppers may also see "high-oleic" versions of sunflower or canola oils on supermarket shelves or high-oleic oils listed on the ingredient lists of processed foods.
These oils have been modified to be richer in oleic acid, which boosts their levels of monounsaturated fat. This damage may even lead to premature aging, certain cancers and heart disease 21 , 22 , These are much more resistant to oxidation than peanut oil. Although peanut oil is advertised for its high smoke point, it may not be the best choice.
It may also help improve insulin sensitivity and blood sugar in those with diabetes. It is very high in pro-inflammatory omega-6 fatty acids and is prone to oxidation, which may increase the risk of certain diseases. With so many other healthy fat choices on the market, it might be wise to choose an oil with more benefits and fewer potential health risks.
