Cholesterol & Bile
Behrman and Gopalan (2005) suggest the following as an accurate account of the real sterol content of plants:
More than 250 steroids have been described in plants. Of these, perhaps sitosterol, which differs from cholesterol by an ethyl substituent at position 24, is the most common. But plants also contain cholesterol both free and esterified. Cholesterol occurs as a component of plant membranes and as part of the surface lipids of leaves where it is sometimes the major sterol. The quantity of cholesterol is generally small when expressed a percent of total lipid. While cholesterol averages perhaps 50 mg/kg total lipid in plants, ....
... For example olive oil typically contains 0.5–2 mg cholesterol per kg and sesame oil about 1 mg cholesterol per kg.
Give the above figures a person would only obtain 50mg of cholesterol from 50g of sesame or olive oil. Given that sesame is 50% ol then you would need 100g to get 50mg of cholesterol, a small amount. See https://www.vegfamily.com/dietician/cholesterol.htm
. . . Typical daily dietary intake of additional cholesterol, in the United States, is 200–300 mg
https://en.wikipedia.org/wiki/Cholesterol#Physiology. . . Adult Treatment Panels suggest the total blood cholesterol level should be: <200 mg/dl

That's 0.2grammes per 100ml or 2grammes per litre, or 9 grammes for 4.5 Lt (68kg body weight)
. . . For a man of about 68 kg (150 lb), typical total body-cholesterol synthesis is approximately 1 g (1,000 mg) per day, and total body content is approximately 35 g, primarily located within the membranes of all the cells of the body.
. . . After being transported to the liver by HDL, cholesterol is delivered to the intestines via bile production. However, 92-97% is reabsorbed in the intestines and recycled via enterohepatic circulation.
Cholesterol is used by the liver to create bile salts to aid the digestion, especially of oils. Usually the body recovers most of the cholesterol form the bile salts in the lower intestine.
