Once a person can recognise cholesterol has a place in biology, it is a lot easier to embrace the idea that all eukaryotes have an adaptive relationship with this biochemical marvel. It is the foundation molecule from which the steroidal hormones are formed and they give rise, in the very least, to the sex lives of mammals.
In the 1970s, Dr. Ancel Keys, who did more to advance fear of cholesterol and healthy saturated fats, conceded, "Cholesterol in the diet doesn't matter much, and we've known that all along." Cholesterol levels do matter, in the sense that they can be left entirely to their own devices.
Keys' fascination with early Russian research circa 1913 had him misled. Some Russians added cholesterol to the diet of rabbits. In so doing, they induced atherosclerosis (heart disease) but neither Keys, nor they, realised the cholesterol they added to the rabbit chow may have become oxidised before the rabbits ingested it.
There should no longer be any doubt that there is a world of difference between the effects of the cholesterol we may eat and any oxidised cholesterol.
One of the great things about vitamin D, ingested or synthesised in the sun, is that is a great antioxidant. Vitamin D is one of the most potent reducing agents in biochemistry and human physiology. It is good that some cholesterol rich foods, like eggs, are also good sources of vitamin D because vitamin D could then combat any oxidative stress traces of oxidised cholesterol may provoke.
Today's a nice day. Without being too brazen, I have just gone outdoor in the back yard fully naked to get maximum exposure, specifically to synthesise some vitamin D from my beloved cholesterol. Just the way nature intended.
