2. What is Peanut Oil?
Peanut oil, also commonly referred to as groundnut oil, is a type of vegetable oil derived from the seeds of the peanut plant, scientifically known as Arachis hypogaea. Despite the name “peanut,” which suggests a nut, peanuts are actually legumes. However, when it comes to the oil, what’s extracted is from the seed of the peanut, making it unique in both composition and classification.
Peanut oil has been used for centuries in various parts of the world, especially in Asia and Africa, for its mild flavor, high smoke point, and versatile cooking properties. It’s a preferred oil for deep frying, stir-frying, and even sautéing because it doesn’t overpower the taste of dishes while still adding a subtle nutty aroma.
In India, peanut oil is a staple in many households, especially in states like Gujarat and Maharashtra. In China and Southeast Asian countries, it is widely used in wok cooking because it can handle high temperatures without breaking down or producing smoke.
There are different versions of peanut oil available in the market today—refined, cold-pressed, and roasted peanut oil, each with its own flavor profile, processing method, and nutrient content.
One of the most attractive qualities of peanut oil is its nutrient composition. It is rich in monounsaturated fats, contains Vitamin E, and has no trans fats or cholesterol, making it a better option compared to many heavily processed oils.
Overall, peanut oil is not only a flavorful cooking oil but also a healthy one when used in moderation. But to truly understand its place in your diet, it’s important to explore whether it fits into the category of seed oils, especially given the confusion around the nature of peanuts themselves.
3. Is Peanut Oil a Seed Oil?
This is one of the most common questions people ask when considering peanut oil: Is peanut oil a seed oil? The answer is: Yes, peanut oil is technically classified as a seed oil.
Let’s break it down. Although peanuts are botanically legumes, not tree nuts, the oil that is extracted comes from the seed part of the peanut. In food science and nutrition, oils that are derived from the seeds of plants are categorized as seed oils, regardless of whether the plant is a legume, grain, or a flowering crop.
To make this clearer, let’s consider a few other commonly used seed oils:
-
Sunflower oil – extracted from sunflower seeds
-
Canola oil – extracted from rapeseeds
-
Sesame oil – extracted from sesame seeds
-
Soybean oil – extracted from soybeans (also legumes)
-
Peanut oil – extracted from the seed of the peanut plant
As you can see, many oils we use every day come from the seeds of plants, and peanut oil fits this category perfectly, even though peanuts are not true botanical nuts.
This categorization matters because seed oils share certain characteristics—for example, many are high in polyunsaturated fats and omega-6 fatty acids, and are often used in cooking due to their high smoke points and neutral or mild flavors.
So, despite some confusion around terminology, peanut oil is indeed a seed oil from both a scientific and culinary perspective. Its classification has implications for both nutrition and cooking performance, which we’ll explore further in the next sections.
Understanding this helps clear the air and also positions peanut oil in the right place when comparing it with other oils in your kitchen.
4. How is Peanut Oil Made?
Peanut oil can be produced using several different methods, and the processing technique greatly affects its flavor, nutritional profile, and best use cases. Let’s take a look at the three most common types of peanut oil based on production methods:
1. Cold-Pressed Peanut Oil
This method involves mechanical pressing of the peanuts without using high heat or chemicals. It is considered the most natural and nutritious form of peanut oil. The oil retains much of the original flavor, aroma, and nutrients found in raw peanuts. It contains a higher amount of Vitamin E and antioxidants, making it ideal for people who prioritize health and natural ingredients. However, because it’s unrefined, its smoke point is lower, making it more suitable for low to medium-heat cooking or dressing.
2. Refined Peanut Oil
This is the most commonly used form of peanut oil in commercial kitchens and restaurants. During refining, the oil goes through neutralization, bleaching, and deodorization, removing allergens and impurities. The result is a neutral-tasting oil with a very high smoke point (around 450°F or 232°C), making it perfect for deep frying and high-temperature cooking. However, the refining process also reduces some of the nutritional content like Vitamin E.
3. Roasted Peanut Oil
Made from roasted peanuts, this oil has a dark color and a rich, intense nutty flavor. It’s commonly used in Asian cuisines, especially in stir-fried dishes and sauces. Due to its strong flavor, it’s best used as a finishing oil or in recipes where the peanut flavor is desired.
Each type serves a different purpose in the kitchen, so choosing the right one depends on your cooking style and health goals.
5. Types of Peanut Oil
Peanut oil is available in several forms, and each type has its own unique characteristics in terms of flavor, nutritional value, and suitability for different cooking methods. Choosing the right type of peanut oil depends on your cooking needs and health preferences. Let’s explore the main varieties:
Refined Peanut Oil
Refined peanut oil is the most commonly available type in supermarkets and restaurants. It goes through processes like bleaching, deodorizing, and refining to remove impurities, allergens, and strong smells. As a result, this oil has a light golden color, a neutral flavor, and a very high smoke point (about 450°F), making it ideal for deep frying, stir-frying, and grilling. However, the refining process strips away some natural nutrients like Vitamin E and antioxidants.
Cold-Pressed Peanut Oil
Cold-pressed peanut oil is extracted mechanically without using heat or chemicals. This traditional method preserves the natural nutrients, flavor, and color of the oil. It has a stronger peanut aroma and taste and is rich in monounsaturated fats and Vitamin E, making it a healthier option. Cold-pressed peanut oil is perfect for low to medium-heat cooking, salad dressings, or finishing oils. It’s popular among health-conscious consumers who prefer minimally processed products.
Roasted Peanut Oil
Roasted peanut oil is made from roasted peanuts, which gives the oil a deep, nutty, and intense flavor. It’s commonly used in Asian cooking, especially in Chinese stir-fry recipes, sauces, and marinades. Due to its bold taste, it’s often used as a flavor enhancer rather than a primary cooking oil.
Blended Peanut Oil
Blended peanut oil is a mixture of peanut oil with other vegetable oils, such as soybean or sunflower oil. It’s more affordable and has a lighter flavor, but it may lack the health benefits of pure peanut oil.
6. Nutritional Value of Peanut Oil
Peanut oil is widely used not only for its cooking performance but also for its impressive nutritional profile. It is especially valued in health-focused kitchens for being low in saturated fat and rich in heart-friendly fatty acids. Let’s break down the nutritional content of peanut oil per 1 tablespoon (13.6 grams):

This nutritional makeup shows why peanut oil is often chosen as a healthy cooking oil. It contains a significant amount of monounsaturated fatty acids (MUFAs), which are known to support heart health, lower bad cholesterol (LDL), and improve good cholesterol (HDL). MUFAs are also linked to better blood sugar control and reduced inflammation.
Peanut oil also includes polyunsaturated fats (PUFAs), which are essential fats your body cannot produce. These play a role in brain function, cell structure, and hormonal balance.
One of the most notable nutrients in peanut oil is Vitamin E, a powerful antioxidant that helps protect cells from oxidative stress and supports skin and eye health.
Additionally, peanut oil contains no cholesterol, which is ideal for those monitoring their cholesterol intake. It also has zero carbs and zero trans fat, making it suitable for low-carb and keto diets.
Whether you’re frying, sautéing, or drizzling over a salad, peanut oil provides a healthy base that complements many dishes without compromising on nutrition.
7. Health Benefits of Peanut Oil
Peanut oil offers a range of health benefits, especially when used in moderation and in its cold-pressed or unrefined form. Its nutritional profile makes it a good alternative to many heavily processed vegetable oils. Here are the key health benefits of peanut oil:
Rich in Vitamin E
Peanut oil is a natural source of Vitamin E, a powerful antioxidant that helps protect cells from damage caused by free radicals. Vitamin E also supports immune function, improves skin elasticity, and plays a role in anti-aging.
Good for Heart Health
Peanut oil is high in monounsaturated fats (MUFA), which help reduce bad cholesterol (LDL) levels and may improve good cholesterol (HDL) levels. These fats are beneficial for cardiovascular health and may reduce the risk of heart disease when used in place of saturated fats.
Anti-inflammatory Properties
Thanks to its healthy fat content and natural antioxidants, peanut oil may help reduce inflammation in the body. Chronic inflammation is linked to diseases such as arthritis, diabetes, and heart disease.
Supports Cholesterol Balance
By lowering LDL and maintaining HDL cholesterol, peanut oil promotes better blood lipid profiles, contributing to overall vascular health and blood pressure regulation.
Skin and Hair Benefits
Cold-pressed peanut oil can be applied directly to the skin or scalp. It moisturizes dry skin, soothes irritation, and can improve scalp health. The presence of Vitamin E supports skin repair and glow.
Energy Booster
The healthy fats in peanut oil are a dense source of energy, making it ideal for those needing calorie-rich but heart-friendly foods.
In summary, peanut oil can be a smart choice for health-conscious individuals, especially when used wisely and alternated with other healthy oils.
8. Is Peanut Oil Healthy?
Yes, peanut oil is considered healthy, especially when used in moderation and in its cold-pressed or unrefined form. Like many seed oils, the health value of peanut oil depends on its processing method, how it’s used, and how often it’s consumed.
The healthiest version of peanut oil is cold-pressed, as it retains more nutrients, antioxidants, and the natural flavor of peanuts. It is rich in monounsaturated fats, which are known to support heart health, reduce bad cholesterol, and improve good cholesterol. It also contains Vitamin E, a fat-soluble antioxidant that promotes skin, eye, and immune system health.
On the other hand, refined peanut oil, although excellent for high-heat cooking, goes through chemical and heat treatment that removes many of its natural nutrients. This version may not offer the same antioxidant and anti-inflammatory benefits as the cold-pressed version, but it is still a better alternative to saturated fats and trans fats found in some commercial cooking oils.
It’s also important to note that peanut oil contains a moderate level of omega-6 fatty acids. While these fats are essential, too much omega-6 (without balancing omega-3 intake) can lead to inflammation in the body. Therefore, it’s recommended to balance peanut oil with other oils like mustard oil, ghee, or olive oil.
Another consideration is peanut allergies. People allergic to peanuts should avoid cold-pressed peanut oil, as it may contain protein traces. However, highly refined peanut oil is usually safe, as the refining process removes allergens.
In conclusion, peanut oil is a heart-friendly, nutrient-rich oil when used properly. Choose cold-pressed peanut oil for maximum health benefits, and rotate it with other healthy oils to maintain dietary balance.

Like any oil, it should be used in moderation and with proper understanding of how it might affect your body.
Peanut Allergy Caution
One of the biggest concerns with peanut oil is its potential to cause allergic reactions in people who are sensitive to peanuts. Cold-pressed or unrefined peanut oil may retain traces of peanut proteins, which can trigger serious allergic responses, including hives, swelling, difficulty breathing, or even anaphylaxis. For this reason, individuals with peanut allergies should completely avoid unrefined peanut oil.
On the other hand, refined peanut oil undergoes extensive processing, which removes almost all the allergenic proteins. Many people with peanut allergies can safely consume refined peanut oil, but it’s always recommended to consult a doctor before doing so.
Omega-6 Imbalance
Peanut oil contains omega-6 fatty acids, which are essential for the body but can become harmful if consumed in excess. A diet too high in omega-6 and low in omega-3 (like fish oil or flaxseed oil) can lead to inflammation, which is linked to chronic diseases like arthritis, heart disease, and diabetes. Therefore, balance is key—rotate peanut oil with oils rich in omega-3s for better health.
Overheating Risks
While refined peanut oil is safe for high-heat cooking, unrefined or cold-pressed versions have lower smoke points and should not be used for deep frying. Heating beyond their limit can lead to the formation of harmful compounds and degrade the oil’s nutrients.
In summary, peanut oil is generally safe and healthy, but people with allergies and those sensitive to omega-6 intake should use it carefully.
