Olive oil and garlic, two staples in Mediterranean cuisine, are more than just flavorful ingredients. They offer a wealth of health benefits that can positively impact your body from head to toe. Separately, they’re beneficial, but when combined, their effects are amplified, creating a synergistic powerhouse of wellness.
The Nutritional Powerhouse of Olive Oil
Olive oil, especially extra virgin olive oil (EVOO), is celebrated for its rich nutrient profile. It’s primarily composed of monounsaturated fats, particularly oleic acid, known for its heart-healthy properties. Beyond fats, olive oil contains significant amounts of antioxidants, including polyphenols and vitamin E.
Oleic Acid: The Heart-Healthy Fat
Oleic acid, the dominant fat in olive oil, plays a crucial role in maintaining cardiovascular health. It helps to lower LDL (bad) cholesterol levels while maintaining or increasing HDL (good) cholesterol levels. This balance is vital for preventing the buildup of plaque in arteries, a major contributor to heart disease. Studies have shown that diets rich in oleic acid can significantly reduce the risk of heart attacks and strokes.
Polyphenols: Antioxidant Champions
Polyphenols are plant compounds that act as potent antioxidants, protecting cells from damage caused by free radicals. Olive oil boasts several important polyphenols, including oleocanthal, oleuropein, and hydroxytyrosol.
