Stanols in archaeological specimens indicate human habitation as a marker of cholesterol excretion.

“so a Stan all is simply saturating that adds other applications because hey if Stan els cannot be absorbed and I would like to have a metric of whether you're absorbing cholesterol or not if I measured cholesterol in your blood shouldn't be there to any appreciable degree because it tells us or bit if it is elevated in your blood for whatever reason and we now know why your intestine just absorb that cholesterol and if it's absorbing cholesterol which it tends not to what is it absorbing an humungous excess cholesterol so cholesterol serves as a biomarker of are you or are you not or what degree of cholesterol absorption is going on in your intestines”
