What Is Peanut Oil?

Peanut oil, also known as arachis oil and groundnut oil, is a popular, vegetable-derived cooking oil and ingredient that is made with, you guessed it, peanuts!

And if you’re wondering, “is peanut oil good for frying,” then you’ll be happy to hear that it absolutely is. In fact, peanut oil is preferred by many for deep frying. The refined version of peanut oil has a smoke point of 450 degrees Fahrenheit and can be used several times before being discarded. It doesn’t absorb the taste of food either, which is key for a good frying oil.

Typically peanut oil has a nutty taste to it which ranges in depth depending on the kind you buy. So, be aware of that if that’s not what you’re looking for. Also, if you are allergic to peanuts, most kinds can spark up an allergic reaction. Refined peanut oil usually won’t, however.

This oil is composed of around 50% monounsaturated fat, 32% polyunsaturated fat and 17% saturated fat. Monounsaturated fat and polyunsaturated fat are considered “healthy fats,” while saturated fat is known as an “unhealthy fat.”

But as you’ll find out in this blog, even polyunsaturated fats can have negative downsides, even though it’s coined a healthy fat.

Types Of Peanut Oil

When you go into the grocery store hunting for peanut oil, you may come across a variety of different kinds. They all serve a purpose, with some being great for high-temperature cooking or low-temperature cooking, while others will save you some money.

Here is a brief list of the different types of peanut oil:

Refined peanut oil: Arguably the most popular version of peanut oil, refined peanut oil is fantastic for frying. As mentioned earlier, refined peanut oil has a 450-degree smoke point. It doesn’t absorb the taste of food and it can be used multiple times before having to be discarded.

Also, refined peanut oil typically has a neutral taste to it, so your meal won’t be altered in that way.

Gourmet peanut oil: Boasting a nutty taste, gourmet peanut oil is usually unrefined and is great as a finishing ingredient.

Peanut oil blends: As the name suggests, you can also purchase blended peanut oil. The oil is mixed with another oil that tastes around the same. It’s one of the cheaper ways to add peanut oil to your frying regimen.

Cold-press peanut oil: This is a low-heat oil that has retained more of its nutrients relative to refined peanut oil. It also has a potential peanut taste.

Is Peanut Oil Bad For You?

Now it’s time to answer your main question: “why is peanut oil bad for you?” There are pros and cons to consuming peanut oil, specifically from a health stance. So, it’s not all bad. However, there are health consequences, just like with most cooking oils on the market.

And we’ll outline some of the reasons peanut oil is bad for you in the section below:

Why Is Peanut Oil Bad For You?

Before we explain some of the reasons why peanut oil is bad for you, it’s important to remember that science and research are always evolving, which includes nutritional standards and norms. Our list of the good and bad aspects of peanut oil comes with that caveat.

But as promised, here are the main reasons why peanut oil can be bad for you, according to the newest research:

Peanut Oil is High in Omega-6 Which Is Not Healthy

A component of peanut oil is omega-6, a fatty acid that has been linked to several health consequences. Omega-6 can cause inflammation in the body. The research isn’t finished on this, but evidence suggests that there is a correlation between high levels of omega-6 consumption and an increase in inflammatory diseases, like obesity, heart disease and cancer.

Specifically, there are a variety of studies that have been released that show a relationship between omega-6 and an increased risk of women developing breast cancer.

Now, just because you consumed peanut oil doesn’t mean you’re automatically going to suffer from the ailments listed above. Moderation is key, as well as a healthy diet. So make sure you’re not overusing peanut oil and ensure you’re eating healthy, whole foods.

Some Peanut Oils Will Cause an Allergic Reaction

Now, this one may be obvious to you. As we mentioned at the start of this blog, peanuts are derived from a peanut plant and used to make peanut oil. If you have a peanut allergy, it’s best to stay clear of peanut oil to avoid sparking up an allergic reaction. Typically refined peanut oil won’t cause a reaction, however, due to the way it’s manufactured. But, different gourmet and cold-pressed peanut oil will likely trigger your allergies.

If you don’t know whether or not you’re allergic to peanuts, and you never include peanuts in your diet, it may be best to contact your doctor before trying any unrefined peanut oils.

The Oil Could Oxidize & Cause Damage to Your Body

Because peanut oil is highly composed of polyunsaturated fats, there’s a risk of it oxidizing when it’s heated. In layman terms, if you consume something that has undergone the oxidation process, your body could be susceptible to free radical damage, which can cause issues and usher in things like premature ageing and cancer.

Is Peanut Oil Good For You?

As mentioned earlier, peanut oil isn’t all bad. There are actually a lot of great benefits to consuming peanut oil. It is mostly composed of monounsaturated fats and polyunsaturated fats, which are known as healthy fats that could help keep you in tip-top shape.

You’ll also find vitamin E, a key antioxidant, in peanut oil, which has a ton of upside to consuming and using.

In the next section, we’ll outline some of the best reasons why you should consider adding peanut oil to your pantry from a health perspective.
