Cooking sprays are typically an olive oil or other vegetable oil in a pressurized can, sometimes thinned with water, and are a great kitchen staple. Because you can coat the pan with a quick spray, you are able to dramatically cut down in fat and calories while ensuring your food doesn’t get stuck in the pan during cooking.
But does a spray really contain zero calories? Nope. A label for cooking spray usually refers to a 1/3 of a second spritz. Remember, a label can legally list 0 grams of fat or zero calories if one serving contains less than a full gram of fat or less than 5 calories. In reality, that 1/3 of a second spritz probably has about 1/4 gram of fat, or 2 or 3 calories. Not to mention - that 1/3 second spritz is pretty short, and I doubt most of us have reflexes that are even that quick! A typical spray to coat a pan probably falls somewhere between 2 and 4 seconds, leaving you with somewhere between 15 and 30 calories. Still a great calorie bargain!
