Examples: Vegetable fats
Olive, canola, soybean, corn and cottonseed oils
Increase in unsaturated fats will Increase of good cholesterol =
lower risk of heart disease

6. Trans-Fats/ Hydrogenated Oils
Trans fatty Acids
Trans fats (AKA partially hydrogenated oils) are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. 
Trans fats give foods a desirable taste and texture.

Examples:
Fried Foods (Fries, Doughnuts, Chicken)
Baked Goods (Pie crust, cookies, crackers, margarine)
