For deep frying or searing at very high temperatures, a refined olive oil—often labeled as "pure" or "light" olive oil—is often the superior choice. This structural stability means that olive oil resists forming harmful compounds like aldehydes and lipid peroxides even when subjected to the high temperatures required for frying.

Furthermore, olive oil is a potent source of polyphenols, which are antioxidants that combat inflammation and cellular damage. However, the quality of olive oil plays a crucial role in mitigating these risks.
Refined olive oil undergoes a filtering process that removes impurities and has a higher smoke point, making it more neutral in taste and ideal for repetitive use. The Science of Smoke Points and Stability The foundation of any oil-based cooking method lies in its smoke point, the temperature at which it begins to break down and produce smoke.

For decades, the prevailing wisdom suggested that the low smoke point of extra virgin varieties made them unsuitable for high-heat cooking, leading many to default to refined vegetable oils. While extra virgin olive oil is the least processed and retains the most antioxidants, its delicate flavor profile can be compromised by high heat.
