8. Extra Virgin Olive Oil
If the Mediterranean diet had a signature ingredient, this would be it. Olive oil is rich in polyphenols and monounsaturated fat, a combination that helps lower inflammation and rebalance cholesterol levels in your favor. Large studies following Mediterranean diets — where olive oil replaces butter and processed oils almost entirely have linked it to significantly fewer cardiovascular events. The key is choosing “extra virgin” on the label, since it retains the most polyphenols during processing. Use it for cooking, dressings, or simply drizzled over vegetables, and let it become your default fat instead of an occasional one.
