Which food most likely contains trans-fatty acids quizlet?
Hydrogenation of unsaturated fats produces some trans-fatty acids, so they are found most often in commercially fried foods and in baked goods and other commercial foods made with partially hydrogenated vegetable oils.
What are the health benefits of trans fats quizlet?
Trans fat increases the level of low-density lipoprotein (LDL or “bad”) cholesterol and decreases the level of high-density lipoprotein (HDL or “good”) cholesterol in the blood — which, in turn, can increase the risk of developing cardiovascular disease.
