Olive oil doesn't get its reputation as a superfood for no reason -- not only does the stuff possibly ward off cancer (thanks to its powerful antioxidants like Vitamin E), but it's also anti-inflammatory and delicious, too. Unlike the solid, artery-clogging fats in butter, olive oil is packed with healthy monounsaturated fats that may actually lower your risk of heart disease; healthy fats can actually promote good cholesterol and help to regulate your blood sugar. But before you buy your next bottle, make sure you know what you're getting -- and that you're purchasing the right one for your particular needs
