Full fat salad dressing is better for you than low-fat or non-fat

Full fat salad dressing is better for you than low-fat or non-fat:

"“According to Dr. Willett, studies dating back to before 1990 had already established that total fat intake is not relevant and not associated with coronary heart disease. However, the type of fatty acids in the diet did matter,....How do you win?” asks Dr. Willett. “You win by replacing the bad fats (saturated and much more so, trans fats) with the good fats.” So, as long as your full fat salad dressing is made without trans fats or partially hydrogenated fats and contains only monounsaturated fats (e.g., olive, canola or peanut oil) or polyunsaturated fats (e.g., corn, soybean and safflower oil), go for it with lots of salad and vegetables and without lots of guilt."
