Refined olive oil or "light" olive oil undergoes processing that removes impurities, raising the smoke point significantly while sacrificing some of the delicate, fruity notes. Oils are composed of saturated, monounsaturated, and polyunsaturated fats.
Understanding Oil Stability and Nutrient Retention During Frying
Avocado oil boasts one of the highest smoke points and a fatty acid profile rich in heart-healthy monounsaccharides. Unrefined oils, like extra virgin olive oil or unrefined walnut oil, retain their natural antioxidants and flavor, but these delicate compounds have low smoke points.
A stable oil maintains its integrity, while an unstable oil will produce aldehydes and other inflammatory compounds, regardless of the temperature on the gauge. The Spectrum of Fatty Acids To understand stability, you must look at the fatty acid profile.

Polyunsaturated fats, while often promoted for their heart health, are delicate and prone to oxidation when heated, making them the least suitable for frying. Saturated fats are hardy and resistant to heat, making them excellent for high-temperature cooking.
