Trans fats
The missing link between saturated and unsaturated fats is trans fats. A trans fat is an unsaturated fat which is heated, causing the fluids to evaporate and the fat to solidify. A hydrogen molecule is then added to the fat. This hydrogenation process alters the chemical structure of the fat. What was originally an unsaturated fat has now become a saturated fat. These fats are man-made and do not exist in nature. What’s their advantage? Take that cookie. Vegetable fats are cheaper and are used in place of butter. They are liquid, however, and don’t have the same semi-solid structure as butter has naturally. By hydrogenating vegetable fats they can be used as a direct replacement for butter. They also keep well. So what if butter is a natural saturated fat and trans fats are unnatural saturated fats? The consumer won’t even know the difference, right?
Right? As it so happens, consumers are waking up to the dangers of trans fats.
How do you recognize trans fatty acids when shopping for food items? Read the labels. Look for hydrogenated or partially hydrogenated oils or fats. You’ll be amazed to see how many products contain trans fats nowadays.
