How Much Do You Know About Fats and Cholesterol?

Trans fats and saturated fats, as well as their relationship with cholesterol has been a pretty confusing topic for many people. A common belief is that fats will develop cholesterol that is harmful to our body. Unfortunately, this is not correct. In reality, not all fats are bad for the body.

Cholesterol is manufactured naturally in our bodies by our liver. It can also be found in certain foods like eggs, seafood, meats, organ meats and animal products. Taking high volume of dietary cholesterol will increase the risk of many medical disorders including cardiovascular disease, heart disease, high blood pressure.

In general, there are 4 types of fats: mono-unsaturated, poly-unsaturated, saturated and Trans fats. The first 2 unsaturated fats are the healthier ones as they increase our HDL (high density lipoproteins, or what we called the 'good' cholesterol) and decrease LDL (low density lipoproteins, or what we called the 'bad' cholesterol). On the other hand, saturated and Trans fats are bad for our bodies as they increase our LDL. The damage caused by trans fats is even serious because they also decrease our HDL.

Foods such as animal fat, animal skin, animal products such as butter, coconut milk and dairy products are good sources of saturated fats. Trans fats are formed when vegetable oils goes through a process called hydrogenation. As such, products that are labeled 'partially hydrogenated' or 'hydrogenated' vegetable oil in the ingredient list do contain trans fats.

Unsaturated fats can be found in vegetable oils like olive oil, canola oil, sunflower oil, and foods like nuts, avocados and oily fish.


In fact, our bodies still require a certain amount of fats for absorption of vitamins as well as other daily functions. Therefore, we should allocate only 10 per cent of our daily caloric intake for saturated and Trans fats, as recommended by health experts, and should take more foods containing unsaturated fats.
