Is it true high amounts of lipid intake is generally bad?
So what is the HDL actually referring to?
Is it referring to the HDL Cholesterol being able to allow more fatty acid to travel through arteries, so less “cloggage”?
Thanks
Chemists should be able to answer this
Actually, it is not a chemical question. 
Cholesterol is insoluble in blood, but is transported in the circulatory system bound to one of the varieties of lipoprotein, spherical particles which have an exterior composed mainly of water-soluble proteins. The main types, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) carry cholesterol from and to the liver. HDL are the smallest of the lipoproteins. They are the densest because they contain the highest proportion of protein. LDL transports cholesterol to arteries, whereas HDL transports cholesterol from arteries to liver for disposal.
