Refined olive oil is often less expensive than extra-virgin or virgin olive oil, but it is also less healthy and less flavorful. Chemical solvents, such as hexane, may be used in the refining process which may have negative health effects. Refined olive oil is significantly lower in the beneficial compounds that may be responsible for the numerous health benefits of virgin and extra-virgin olive oil. Rand refined olive oil is still a good source of healthy monounsaturated fats (as is extra-virgin and virgin olive oil). Monounsaturated fats have been linked to improved cardiovascular health, reduced inflammation, and reduced risk of cancer.
