As a health and nutrition expert with a background in biochemistry, I'm often asked about the impact of various foods on our health, particularly concerning cholesterol levels. Cholesterol is a waxy substance that's present in the blood and cells of the body. High levels of "bad" cholesterol, or low-density lipoprotein (LDL), can increase the risk of heart disease and stroke. On the other hand, "good" cholesterol, known as high-density lipoprotein (HDL), helps to remove LDL from the bloodstream, thus protecting against heart disease.
Extra virgin olive oil (EVOO) has been a staple in the Mediterranean diet for centuries and is often touted for its potential health benefits. Let's delve into the science behind its cholesterol-lowering properties.
### Composition of Extra Virgin Olive Oil
EVOO is rich in monounsaturated fats, specifically oleic acid, which makes up about 55-83% of the oil. Monounsaturated fats are known for their heart-healthy properties. They can help to increase HDL, the "good" cholesterol, while also reducing levels of LDL, the "bad" cholesterol. This dual action is beneficial for cardiovascular health.
### Impact on Cholesterol Levels
Research has shown that replacing saturated fats with monounsaturated fats can lead to a decrease in LDL cholesterol levels. A study published in the *European Journal of Clinical Nutrition* found that a Mediterranean diet enriched with EVOO improved cardiovascular risk factors, including a reduction in LDL cholesterol levels.
### Mechanisms of Action
1. Improvement in LDL Particle Size: Monounsaturated fats in EVOO can increase the size of LDL particles. Larger LDL particles are less likely to penetrate arterial walls and cause plaque buildup.
2. Enhanced HDL Function: EVOO may also improve the function of HDL particles, making them more effective at removing cholesterol from the arteries.
3. Anti-Inflammatory Effects: Olive oil contains bioactive compounds like polyphenols, which have anti-inflammatory properties. Inflammation is a risk factor for heart disease, and reducing it can contribute to better heart health.
4. Antioxidant Properties: The antioxidants in EVOO can help to reduce oxidative stress, which is linked to the development of atherosclerosis, a condition where plaque builds up inside the arteries.
### Clinical Studies and Evidence
Several clinical trials and observational studies support the heart-healthy benefits of EVOO. For instance, the PREDIMED study, a large-scale study conducted in Spain, found that a Mediterranean diet supplemented with EVOO was associated with a reduced incidence of major cardiovascular events.
### Recommendations and Considerations
While EVOO can be part of a heart-healthy diet, it's important to consume it in moderation. All fats, even healthy ones, are calorically dense. Overconsumption can lead to weight gain, which can negate the cholesterol-lowering benefits.
Additionally, it's crucial to choose high-quality EVOO. Lower-grade olive oils may not have the same health benefits due to differences in processing and the presence of fewer beneficial compounds.
### Conclusion
In conclusion, **extra virgin olive oil is indeed good for lowering cholesterol** when used as part of a balanced diet that emphasizes whole, unprocessed foods. It's a source of monounsaturated fats that can help to improve the cholesterol profile by increasing HDL and decreasing LDL. However, it should be consumed in moderation and as part of an overall healthy lifestyle that includes regular exercise, a balanced diet, and other heart-healthy practices.

Because extra virgin olive oil is rich in monounsaturated fats. These are the fats which increase good cholesterol and reduce the bad type contrasting with other foodstuffs which are full of saturated fats, responsible in part for the increase in cholesterol.Jan 24, 2017
