"Cholesterol plaque" refers to a buildup of fatty substances (cholesterol) in the walls of our blood vessels. This buildup can narrow the blood vessels and interfere with the flow of blood, potentially causing various health problems.
Full definition
Levels below 100 mg / dl are considered optimal, as people with that reading are less likely to
develop cholesterol plaques as they age.
New research suggests that an organic byproduct generated by intestinal bacteria may be responsible for the formation
of cholesterol plaques in the arteries of individuals with decreased kidney function.
Any adult may be walking around with arteries loaded
with cholesterol plaque that is silent for years until it is so severe that angina, a heart attack or a sudden death occurs.
I don't know about long term affects, because I've never read anywhere that temporary arterial constriction
causes cholesterol plaque to build up.
Additional causes include: atherosclerosis (
cholesterol plaques like humans get) associated with hypothyroidism, hypertriglyceridemia (elevated blood fat levels) in miniature schnauzers, and cancer.
Dogs do not get the athlerosclerosis (
cholesterol plaque) problems that humans get, so I am not sure there is any advantage to olive oil in dogs but it does have a nicer taste, at least in my opinion.
