What Is Peanut Oil? How Is It Good For You?

Often referred to as groundnut oil, this is a vegetable oil extracted from the seeds of the peanut plant.

In fact, there are different varieties of peanut oil. One is the refined peanut oil, which is refined, bleached, and deodorized. The process removes allergens in the oil, and this makes it safe for people with peanut allergies. We also have cold-pressed peanut oil, where the peanuts are crushed, and the oil is forced out. This one retains more flavor and nutrients. The third variety is the gourmet peanut oil that is usually roasted and hence has an intense flavor. The last variety is a peanut oil blend, where the oil is blended with another oil with a similar taste.

The goodness of peanut oil primarily boils down to its vitamin E content, an antioxidant proven to reduce free radical damage and cut heart disease risk (1). There’s more, by the way.

What Are The Benefits Of Peanut Oil?

1. Peanut Oil Boosts Heart Health

We already saw how the vitamin E in the oil could protect the heart. It fights free radicals, which can otherwise cause heart disease (2). The oil is also rich in monounsaturated and polyunsaturated fats that are linked to a lowered risk of heart disease. As per the American Heart Association, these types of fats can reduce heart disease risk by as much as 30% (3).

Some research also throws light on the ability of peanut oil to lower bad cholesterol levels.

2. Helps Fight Cancer

The polyphenol antioxidants in peanut oil fight free radicals, and this can contribute to cancer prevention. In fact, peanut oil is a natural tonic that boosts immune levels.

3. Enhances Cognitive Health

The vitamin E in peanut oil, as per studies, can prevent age-related mental decline. Thanks to its antioxidant properties, the oil enhances cognitive health, especially in older individuals (4).

4. Can Improve Insulin Sensitivity

Studies show that a combination of monounsaturated and polyunsaturated fats (as present in peanut oil) can enhance insulin sensitivity in diabetics. In another study, replacing dietary saturated fat with polyunsaturated fat improved insulin secretion in diabetes patients (5).

5. Peanut Oil Might Relieve Joint Pains

Some research says how peanut oil is used to relieve debilitating joint pains. The oil is applied to the skin directly and massaged well, and this can offer some relief.

However, there is insufficient research on this. So, please consult your doctor before you use the oil for this purpose.

6. Delays Signs Of Aging

Applying peanut oil topically can offer anti-aging benefits. And this is where we talk about vitamin E once again. The antioxidant fights free radicals, which otherwise might accelerate aging signs like wrinkles and fine lines.

7. Treats Dry Skin

Topical application of peanut oil also helps treat dry skin, thanks to its moisturizing properties. You can apply the oil to your face and other affected areas and leave it on for about 20 minutes. Then, take a bath as usual.

8. Boosts Hair Growth

The vitamin E and other fats in the oil benefit your hair in more ways than one. The oil reduces protein loss from the hair and even thickens your tresses. It also moisturizes your split ends and regenerates damaged hair.

9. Helps Treat Scalp Psoriasis

The antioxidants in peanut oil treat dandruff, and in some cases, can even aid the treatment of scalp psoriasis. This can also be attributed to the moisturizing properties of peanut oil.

These are the ways peanut oil can benefit your health. But there are other ways this oil can be helpful.

How Else Can Peanut Oil Be Used?

There are different ways peanut oil can be used:

  • For Cooking

Peanut oil is low in saturated fats and rich in monounsaturated and polyunsaturated fats. Which is why it is ideal for cooking. It works particularly well with Asian foods that are predominantly prepared in the wok.

  • For Making Soap

You can also use the oil to make soap. And thanks to its conditioning properties, the soap can boost skin health. One downside is the oil may not last long in your soap as it can turn rancid quite fast.

  • For Making Biodiesel

Peanuts are more than 50% oil, which is why one acre of them produces about 123 gallons of oil. Though this alternative fuel is slightly expensive, it might be where the future lies.

  • For Vaccines

In fact, this has been happening since the 1960s. The oil was used in influenza shots to lengthen immunity in patients.

These are certain other ways peanut oil is used. And yes, we guess you want to know what else the oil contains. So, here you go!
