An Introduction to Polyunsaturated Fats
Polyunsaturated fats are an essential fatty acid (EFA) which means they cannot be produced by your body and must be sourced from diet alone. They can be found in various foods including dairy products, oily fish and nuts. There are two main types; omega 3 EFAs and omega 6 EFAs. In this article I will be covering this type of dietary fat in greater detail.
Dietary fats are all made from a combination of carbon and hydrogen atoms. Polyunsaturated fats contain two or more double carbon bonds (hence the name ‘poly’). They have the lowest melting point of all three natural fats (saturated, monounsaturated and polyunsaturated) and are liquid at room temperature.
As discussed above there are two main types of polyunsaturated fat; omega 3 EFAs and omega 6 EFAs. Whilst they both fall under the same fat group there are some key differences between the two which I have listed below:
1) OMEGA 3 EFAS
Omega 3 EFAs can be found in cold water fish, dairy products, eggs and meats. They offer numerous health benefits which include:
- Healthy Vision.
- Helping You Absorb Fat Soluble Vitamins.
- Improved Brain Health.
- Reduced Cancer Risk.
- Reduced Heart Disease Risk.
- Reduced Inflammation.
However, excess consumption of omega 3 EFAs is dangerous and can lead to the following negative symptoms:
- Increased Blood Glucose Levels.
- Thinning Blood.
2) OMEGA 6 EFAS
Omega 6 EFAs can be found in nuts, certain oils and wholemeal products. They too support good health and offer the following benefits:
- Healthy Skin.
- Reduced PMS Symptoms in Women.
- Strong Bones.
However, like with omega 3 EFAs eating too many omega 6 EFAs can be damaging to your health and lead to:
- Cancer.
- Depression.
- Heart Disease.
- Inflammation.
- Interference with Omega 3 EFAs.
When it comes to enjoying the benefits and avoiding the risks, balance and moderate consumption is the key. This can be achieved by eating fish regularly (fish is one of the best sources of omega 3 EFAs available), minimising your consumption of processed goods (processed goods cause your EFA consumption to be unbalanced as they contain very high levels of omega 6 EFAs but very low levels of omega 3 EFAs) and making sure that your diet does not contain excessive levels of polyunsaturated fats.
I hope this article has given you a better understanding of this dietary fat. Whilst it is essential for good health some precautions have to be exercised. So make sure you consume polyunsaturated fats sensibly and they will keep your body running smoothly.
