2. Olive oil
People from the Mediterranean region have the lowest levels of diabetes and heart disease – and it may be thanks to olive oil. Olive oil contains half the fat of regular vegetable oil and is also rich in antioxidants. It helps to cut down the risk of heart disease and keeps the cells healthy. You can sauté vegetables in olive oil or drizzle the oil over salads, dips and even use it to sear meat or fish.
