Certain oils like olive and canola can offer your body the healthy fat it needs. They're low in saturated fat and high in monounsaturated fat, considered the healthier kind of fat that can help lower your LDL (bad) cholesterol. That does not mean you're eating foods that are drowning in oil. A fat is still a fat, no matter what. A tablespoon of oil can add up to 100 calories!
When cooking or adding oil to foods, try using an oil mister, like this one from Crate and Barrel ($14.95) or you can try the Misto ($9.95). Through a pumping action, you can give a light mist of regular or infused oils to salads, bread, pans, veggies, meats, and anything else you add oil to. It's easier than using a brush, and healthier than just pouring a whole bunch straight from the bottle. It's a great way to lighten your meals, and add flavor but not too much extra fat and calories.
