Cholesterol is the main precursor in the synthesis of many crucial hormones including vitamin D3 (the sunlight hormone).
The "anti-cholesterol movement" might be just one of the many ways to depress and demoralize the masses, get them hooked on more pharmaceuticals (antidepressants), make them avoid healthy foods like eggs, and make them more easily controlled, like fluoride in the drinking water.
When did the anti-cholesterol movement start? I dunno. Around the time they banned trytophan/released Prozac?
