Loading up on trans fats—any time of day
If you have high cholesterol, you’re probably used to being warned about the danger of trans fats—man-made hydrogenated oil that makes food less likely to go bad. Trans fats raise your ‘bad’ cholesterol, or LDL, while lowering your body’s amount of ‘good’ cholesterol, HDL. You can find them in most baked goods, pre-packaged snacks like chips and microwave popcorn and fried foods. Some restaurants even add a form of trans fats to their deep fryers so that they have to change the oil less frequently.
