It's the collapsing/hardening of the arteries that is the problem... mainly caused by years of eating breads and refined sugars.
What? Collapsing of the arteries?
An arterial blockage is caused by plaque consisting of cholesterol, lipids, calcium and other debris building up to the point that it blocks the arteries.
A stroke typically occurs when there is blood clot, blockage or plaque build up is torn off the side of the blood vessel, allowing blood to flow out into the surrounding areas.
I would agree that refined sugars definately are an integral part of heart disease, but its not the only cause. Excess amounts of protein, fats, including cholesterol and a lack of fiber are all factors.
If you have inflammation and damage in your blood vessels and you have large amounts of cholesterol particles floating around, they are bedding down into the endothelium along with white blood cells to create big mess. There is no point when it is ok to have vast amounts of cholesterol and or fat in your blood (high tryglycerides).
Excess and incorrect food types is the cause of the problem(plus other fators, stress, lack of exercise etc) but cholesterol is one of the building blocks of the symptom. Yes we absolutely need cholesterol for various functions, but thinking hey its ok to having large amounts of it kicking around in your blood is simply a flawed concept.
