Bad fats are saturated and trans-fats. I spoke about these fats earlier but did not explain why we consider then 'bad’. These fats are 'bad' or unhealthy for us to eat because they are linked to cardiovascular disease. Another reason these fats are bad for us is that they raise our cholesterol more than any other food item in our diet.
If your diet consists of foods that raise your cholesterol then the following will happen: your arteries begin to get clogged which makes them smaller and restricts the flow of blood through your body. As a result of your arteries being clogged your heart has to work much harder to pump the blood through all your arteries. If your arteries become so clogged that the blood cannot circulate then you have reached a point of having a life changing event, a very bad event.
The fat that is considered the worst of the bad fats is trans-fat. Another method to identify a fat as a trans-fat is if you see partially hydrogenated on the label. It is almost guaranteed that the product contains trans-fats. Trans-fats lower the good cholesterol (HDL) and raise the bad cholesterol (LDL).The only purpose of trans-fats is to increase the shelf life of the food item; there is no nutritional value to a trans-fat.
