Peanut Oil vs Groundnut Oil: Key Differences & Uses

Peanut oil and groundnut oil are often used interchangeably, but they differ in origin, composition, and flavor. Understanding these distinctions helps you choose the right oil for cooking, skincare, and nutrition.

What Are Peanut Oil and Groundnut Oil?

Despite the name, both oils derive from the same plant—Arachis hypogaea—but regional terminology varies. Peanut oil is commonly used in the U.S., while groundnut oil is preferred in many Asian and African cuisines. Scientifically, they are nearly identical, with minor variations in fatty acid ratios due to processing methods.

Nutritional Profile & Health Benefits

Both oils are rich in monounsaturated fats, especially oleic acid, which supports heart health and helps reduce bad cholesterol (LDL). Peanut oil contains higher levels of vitamin E—an antioxidant that boosts skin health—and lower saturated fat compared to coconut or palm oils. Groundnut oil shares similar benefits, with comparable omega-6 content, useful for maintaining cell membranes and hormone balance.
Recent studies from 2024 confirm no significant difference in smoke points—both heat well for frying and sautéing—but peanut oil has a slightly nuttier aroma, enhancing dishes like stir-fries and marinades.

Culinary Applications

Cooking method shapes oil choice. Peanut oil’s distinct flavor elevates Asian stir-fries, Thai curries, and Mexican tacos. Its medium smoke point (~450°F / 230°C) suits medium-heat cooking without burning. Groundnut oil, often blended in African stews or West African jollof rice, offers a neutral base that doesn’t overpower ingredients. Both are stable at moderate heat but avoid high-temperature smoking to preserve nutrients and avoid harmful compounds.

Skincare and Wellness Uses

Beyond the kitchen, these oils shine in natural skincare. Groundnut oil, rich in vitamin E and fatty acids, moisturizes dry skin and reduces inflammation, making it ideal for lotions and balms. Peanut oil, with its high vitamin E and antioxidant content, slows signs of aging and supports skin barrier function. Both oils are non-comedogenic, suitable for sensitive skin, and often found in premium organic formulations.

Choosing Between Peanut Oil and Groundnut Oil

When selecting, consider your recipe’s flavor profile and cooking temperature. For bold, nutty dishes, opt for peanut oil. For subtle, neutral flavor in stews or baking, groundnut oil works best. Always check labels for processing methods—cold-pressed oils retain more nutrients.

Conclusion

While peanut oil and groundnut oil are practically interchangeable in most uses, their names reflect regional preferences and occasional processing nuances. Both offer heart-healthy benefits, neutral smoke points, and versatile applications from kitchen to skincare. Try them both and explore how each enhances your meals and wellness routines.
For optimal results, store oils in cool, dark places to preserve freshness, and check expiration dates regularly. Whether you choose peanut or groundnut oil, quality matters—opt for unrefined, cold-pressed varieties whenever possible.
