How Does Cholesterol Relate To Fats In Food?

Cholesterol is either formed in our bodies by our livers or acquired from foods like eggs, seafood, meats, organ meats and animal products. If we have too much cholesterol in our body (or more precisely, bad cholesterol), we will be at a higher risk of developing cardiovascular disease and other diseases.

Then, what are fats? In general, there are 4 types of fats, namely saturated, mono-unsaturated, polyunsaturated, and trans fats.

The unsaturated fats increase our HDL (high density lipoproteins or the 'good' cholesterol) and decrease our LDL (low density lipoproteins or the 'bad' cholesterol). Trans fats do just the opposite: reduce HDL and raise LDL, and saturated fats are known to raise both HDL and LDL.

Mono-unsaturated fats are found in olives; olive oil; canola oil; peanut oil; cashews, almonds, peanuts and most other nuts; avocados, while poly-unsaturated fat is available in corn, soybean, safflower and cottonseed oils; fish.

Saturated fats can be found in foods like animal fat, animal skin, animal products such as butter, and dairy products. Trans fats are formed when vegetable oil goes through a process known as hydrogenation. Therefore, products that have 'partially hydrogenated' or 'hydrogenated' vegetable oil printed in their ingredient list do contain trans fats.

It is not easy to find a meal without fats when we dine out, especially at fast-food outlets. But we must understand one fact: we do need a certain amount of fats for absorption of vitamins as well as other daily functions. Since unsaturated fats are healthier, our meals should comprise most of this kind of fats. On the other hand, we should cut down the amount of saturated fats and trans fats and they should take up only 10 per cent of our daily caloric intake.
