Eat Well, Live Well - Fats

    7698 - Fats pictureFat has developed a bad reputation in recent years, but it is an essential nutrient required by our body.  They provide energy during rest, sleeping and gentle exercise.  They are essential in our diets to protect our vital organs and keep us warm by providing a layer of insulation underneath our skin.

    Types of fat

    Monounsaturated and polyunsaturated fats (also known as the 'good' fats).  These fats should be the primary source of fat intake.

    Saturated fat (also known as the 'bad' fat) which should not be consumed excessively as it can lead to a number of health issues including cardiovascular disease, high blood pressure, high levels of bad cholesterol and obesity.

    Finally, there's trans-fat, this type of fat has no nutritional value.  It reduces the levels of good cholesterol in the blood stream and can increase risk of cardiovascular disease.  Trans fats are found in a low level of some foods such as meat and dairy products.

    Hydrogenated vegetable oil may also contain trans fat, so always check the label as the supplier must declare this.

    How much do I need?

    Fat should make up 25-35% of our diet.  When looking at food labels, be sure to check the amount of saturated fat in the product.  A high level is more than 20g per 100g (5g per portion) and a low healthy level is less than 3g per 100g (1.5g per portion).

    Recommended daily intakes for adults:

     Daily intake Female Male
