Why are fat free dressings harmful?

This fat trap of fat free dressing is often the most surprising. While a full-fat dressing can add a abundance of calories to a salad, fat-free dressings can do something else. Certain nutrients found in vegetables are only fat-soluble, meaning you need a little bit of fat in order for the body to absorb the nutrients. In addition, fat-free dressings may make you miss out on the antioxidant value of vegetables. The American Journal of Clinical Nutrition found that those who used fat-free dressings didn’t benefit from the lycopene or beta carotene content of their vegetables. Plus, fat is satiating, meaning a tablespoon or two of dressing with fat in it makes a salad more filling. This could prevent grazing and nibbling on other foods throughout the day.
