Zašto bismo trebali jesti maslinovo ulje svaki dan?

New research underscores the importance of incorporating high-quality extra virgin olive oil into daily diets due to its wide-ranging health benefits, according to experts in nutrition and public health. The findings highlight how olive oil supports cardiovascular health, digestion, and metabolic balance, reinforcing its role as a cornerstone of the Mediterranean diet. Dr. Yianna Chatzidiakou, a nutritionist based in Greece, emphasizes that these benefits stem from the unique composition of extra virgin olive oil, particularly its high concentration of monounsaturated fats and antioxidants. The primary health benefit attributed to extra virgin olive oil lies in its ability to support heart health. Rich in monounsaturated fats and oleic acid, it effectively lowers low-density lipoprotein (LDL) cholesterol, often referred to as “bad” cholesterol, while simultaneously increasing high-density lipoprotein (HDL) cholesterol, known as the “good” variety. This dual action contributes significantly to reducing the risk of cardiovascular diseases, including atherosclerosis and coronary artery disease. Beyond its impact on cholesterol levels, extra virgin olive oil is also notable for its high content of antioxidants such as vitamin E and polyphenols, including oleocanthal. These compounds play a crucial role in neutralizing free radicals, thereby protecting cells from oxidative stress and contributing to cellular longevity. The presence of these antioxidants also provides anti-inflammatory properties, further supporting overall health and potentially reducing the risk of chronic diseases. In addition to its cardiovascular benefits, olive oil positively influences digestive health. It aids in promoting regular bowel movements and can help protect the stomach lining from developing ulcers. Moreover, it enhances the absorption of fat-soluble vitamins such as A, D, E, and K from other foods, ensuring better nutrient uptake and utilization by the body. Another key advantage of consuming extra virgin olive oil is its potential to regulate blood sugar levels. Studies suggest that it may assist in stabilizing glucose levels, offering a protective effect against the onset and progression of type 2 diabetes. This makes it a valuable component of dietary strategies aimed at managing or preventing metabolic disorders. Contrary to common misconceptions, cooking with extra virgin olive oil does not diminish its health benefits. In fact, its monounsaturated fats remain stable even when heated, preserving their integrity and enhancing the absorption of nutrients from other ingredients during the cooking process. This stability allows it to be an effective medium for frying, as it maintains its structural integrity at high temperatures, typically up to around 180–210°C (356–410°F). This property sets it apart from many other oils that contain higher amounts of polyunsaturated fats, which tend to break down more readily under heat, potentially forming harmful compounds. Despite its numerous advantages, it is essential to consider the caloric density of olive oil. Each tablespoon contains approximately 135 kilocalories, meaning that its consumption should be balanced with overall daily energy needs to avoid excessive calorie intake. Experts recommend integrating it into a well-rounded diet rather than using it excessively, ensuring that it complements other nutritious elements of one's meal plan. Dr. Yianna Chatzidiakou, who works as both a nutritionist and a scientific associate at the Center for Public Health Research and Education of the Academy of Athens, advocates for the inclusion of olive oil in everyday meals. Her work highlights the importance of quality over quantity, emphasizing that choosing high-grade extra virgin olive oil ensures maximum health benefits. She notes that the Mediterranean diet, which traditionally includes generous amounts of olive oil, has long been associated with improved longevity and reduced incidence of chronic illnesses. Consumers looking to incorporate olive oil into their routines should prioritize selecting products labeled as "extra virgin," which indicates minimal processing and retention of natural nutrients. Whether used raw in salads or cooked in dishes, this versatile ingredient continues to offer substantial health advantages when consumed regularly as part of a balanced lifestyle.
