There’s a lot of fear associated with cholesterol, with it being linked to an increased risk of heart disease. But, what you may not know is that cholesterol is required for a number of different reasons; hormone synthesis, as an antioxidant, aids the bodies healing process, is required to form vitamin D, neurotransmitters and is also needed for our cell membrane structure (the outer layer) (Marieb, Hoehn & Hutchinson, 2013).
Cholesterol is found in the foods we eat, but we’ve been led to believe that dietary cholesterol will increase your blood levels, when in fact our liver produces about 85% of it. Dietary cholesterol will not effect your bodies cholesterol levels, saturated fat however will & you know what else will?
STRESS.
When you’re stressed the body creates more cholesterol as it helps to mop up endotoxins. Endotoxins are released during this time of stress and are damaging to the body, creating inflammation. So, to counteract this effect, cholesterol is produced (Marieb, Hoehn & Hutchinson, 2013).
Diets low in saturated fats (commonly in vegan/vegetarian diets) can reduce the total level of cholesterol within the body, and this can result in depression and anxiety (Colin, Reggers, Castronovo & Ansseau, 2002; Papakostas et al, 2004).
As I’ve mentioned earlier, cholesterol is needed for hormone synthesis. Sex hormones testosterone, progesterone and estrogen are all dependent on cholesterol. Cholesterol is also a pre-cursor to vitamin D, an essential fat-soluble vitamin required for multiple functions in the boy (too many to list here).
Moral of the story; cholesterol is GOOD, its needed by the body and it’s also created by the body. Stress management is key for all aspects of health but especially when it comes to cholesterol management, and as always, be kind to yourself x
