    if I am not mistaken oleic acid is ~70% of the fatty acid make up of EVOO and that is where the benefit to HDL attributed.

    Klaus, I trust your mind on this one. maybe it would be helpful if you could explain this in layman's terms. Maybe that is why a good EVOO has a peppery burning sensation if you slurp or drink it solo.
    Fatty Acids:
    Olive Oil is a complex compound made of fatty acids, vitamins, volatile components, water soluble components and microscopic bits of olive. Primary fatty acids are Oleic and linoleic acid with a small amount of linolenic acid.
    • A fatty acid has the general formula: CH3(CH2)nCOOH where n is typically an even number between 12 and 22
    • If no double bonds are present the molecule is called a saturated fatty acid.
    • If a chain contains double bonds, it is called an unsaturated fatty acid.
    • A single double bond makes a monounsaturated fatty acid
    • Oils with more that one double bond are called polyunsaturated fatty acids.
    • Oleic acid is monounsaturated and makes up 55-85% of olive oil
      (C17H35COOH) or CH3-(CH2)7-CH=CH-(CH2)7-COOH also known as oleate.
      The IUPAC name would be cis-9-octadecenoate
    • Linoleic is polyunsaturated and makes up about 9%
      (C17H29COOH) or CH3-(CH2)4-CH=CH-CH2-CH=CH-(CH2)7-COOH
    • Linolenic, which is polyunsaturated, makes up 0-1.5%
