• Similar to EVOO, but with a slightly higher acidity level
• Acidity level: Less than 1.5%
• Still a good option for cooking and salad dressings
• Contains antioxidants, but not as concentrated as EVOO

3. Refined Olive Oil

• Obtained from chemically refined lower-quality oils
• Acidity level: Less than 0.3%
• Neutral in flavor and aroma
• Suitable for deep-frying or baking, where high heat is involved

4. Pomace Olive Oil

• Made from the residue of olive pressing
• Lowest quality and most acidic (up to 1.5%)
• Suitable for industrial use or as lamp oil

Health Benefits of Olive Oil

Olive oil, particularly extra virgin olive oil, is renowned for its health-promoting properties. Research has linked it to various benefits, including:

1. Cardiovascular Health:

• Reduces LDL ("bad") cholesterol: EVOO contains antioxidants and monounsaturated fats that help lower LDL cholesterol levels and improve the HDL ("good") cholesterol ratio.
• Lowers blood pressure: The oleic acid in olive oil has been found to dilate blood vessels, reducing blood pressure.
• Prevents blood clots: EVOO's anti-inflammatory properties may prevent blood clots from forming.
• Reduces risk of heart disease: Studies have shown that regular consumption of olive oil is associated with a lower risk of heart disease.

2. Anti-Inflammatory Properties:

• Contains polyphenols: These antioxidants help reduce inflammation throughout the body, which is linked to various chronic diseases.
• Inhibits COX-2 enzyme: EVOO can block the COX-2 enzyme, which is involved in inflammation and pain.

3. Cognitive Health:

• Protects against Alzheimer's and Parkinson's: The antioxidants in olive oil may help slow down cognitive decline and reduce the risk of neurodegenerative diseases.
• Improves memory and learning: Studies suggest that EVOO may enhance cognitive function and memory, especially in older adults.

4. Cancer Prevention:

• Reduces cancer risk: Olive oil's antioxidant and anti-inflammatory properties may protect against certain types of cancer, including breast, colon, and skin cancer.
• Promotes cell death in cancer cells: Some studies indicate that EVOO can induce cell death in cancer cells.

5. Weight Management:

• High in monounsaturated fats: These healthy fats promote satiety and may aid weight loss by regulating appetite.
• May increase metabolism: Some research suggests that olive oil may slightly increase metabolism, leading to a small increase in calorie burn.

How to Consume Olive Oil

To reap the maximum benefits of olive oil, it should be consumed in moderation. Here are some recommendations:

1. Drizzle on Salads and Vegetables:
