Some say that naturally occurring trans fats (such as conjugated linoleic acid [CLA]) are not as harmful as other trans fats. Is it true?
Trans fats, including CLA, occur naturally in beef, lamb, and full fat dairy products. Studies suggest that CLA may not have the same negative effects on blood cholesterol that partially hydrogenated oils do, although the other trans fats in meat do. However, these foods are high in saturated fats and consumption should be minimized. The American Heart Association recommends eating less than 1% of your calories from trans fats from all sources.
