Cholesterol: friend or foe?
Cholesterol is not the ‘villain’ it has been portrayed to be. In fact, it is a vitally important molecule for our overall health.
Below are some of its important functions:
* It is a ‘parent’ molecule from which steroid hormones are synthesized; these include: cortisol, testosterone, progesterone, oestrogen.
* It is used by the body to form bile acids which are important for the digestion of fats.
* It is an essential component of cell membranes.
* It is involved in our immunity
* It is a precursor to Vitamin D.
* Our brain is highly dependent on cholesterol for proper functioning; although, the brain forms only 2% of total body weight it uses about 25% of body’s cholesterol!
Some interesting facts:
* Most of your cholesterol is made by your liver.
* Cholesterol is not a problem per se, it’s the oxidised cholesterol that is a problem.
* The size of your cholesterol particles offers a deeper insight into your health, rather than the ratio of ‘bad’ and ‘good’ cholesterol. You want more of those fluffy, buoyant LDL - A particles than those small, hard, dense LDL - B particles.
* Not all HDL cholesterol is created equal; there are various subclasses of HDL (e.g. HDL-2 is ‘good’, while HDL-3 has a detrimental effect on our health as it’s pro- inflammatory).
As you can see this molecule deserves a place of honour since it is involved in so many aspects of our health! One certainly doesn't need to fear cholesterol.
