The specific balance of these fats, alongside the presence of minor bioactive compounds, determines much of its nutritional value. These fats help reduce low-density lipoprotein (LDL) cholesterol, commonly known as "bad" cholesterol, while potentially maintaining or even increasing high-density lipoprotein (HDL) cholesterol.
Peanut Oil Nutrition Facts: Understanding Fatty Acids and Antioxidants
Here is a breakdown of the typical fatty acid content found in standard refined peanut oil: Fat Type Approximate Percentage Monounsaturated Fats (Oleic Acid) 40-50% Polyunsaturated Fats (Linoleic Acid) 30-40% Saturated Fats 15-20% Heart Health and Fatty Acids The high concentration of monounsaturated fats, similar to that found in olive oil, is the primary reason peanut oil is often labeled as a heart-healthy choice. Conversely, unrefined or cold-pressed peanut oil retains more of its natural antioxidants, such as vitamin E and phytosterols, offering a richer flavor profile but a lower smoke point, making it more suitable for low-heat cooking or as a finishing oil.
Refined peanut oil boasts a smoke point of approximately 450°F (232°C), placing it among the most stable cooking fats. Although refined oil is generally considered safe for many with allergies due to the protein removal process, medical professionals often advise extreme caution.

Unrefined Varieties Not all peanut oil is created equal, and the processing method dramatically alters its nutritional and sensory properties. Peanut allergies are among the most common and severe food allergies, and the proteins responsible for these reactions can sometimes persist in highly refined oils.
