When it comes to healthy oils, extra virgin olive oil -- EVOO for short -- is the top choice for your healthy pantry.Because it's the first press of the olives, extra virgin olive oil not only tastes better, but also has higher levels of antioxidants and other micronutrients that may help protect against diseases, from Alzheimer's to breast cancer. When you shop for EVOO, avoid imitators. Look for the words "100 percent Extra Virgin Olive Oil" on the label. The oil must be pressed from olives alone, not mixed with nut or seed oil.
