....before the blood tests for TSH ruled the world of medicine it was assumed that if your cholesterol was high then you possibly also had an UAT. Cholesterol is mostly produced in the body - over 80% I believe - and very little from food. The Food Agencies are almost as bad as the Drug Agencies and just want to make money out of the unsuspecting public ! But of course we all know better !
Cholesterol is there for a reason - the brain needs lots and VitD cannot be produced without it and lots of other very good things. How are your vitiamins ? I know many people disregard Homocysteine - which MAY be a better indicator of Heart/stroke problems. If it's high then the treatment is just Folic Acid and the B Vitamins. Probably why it is not present as a regular test in mainstream medicine as there is no drug to lower it !
Usually high Homocysteine accompanies raised cholesterol. It was also found in the plaque of blood vessels in the early research - so it was not cholesterol alone that was causing the problem. Many think it is oxidation - rust ? - that blocks the arterial system....from inflammation somewhere in the body. Lots of information out there ....
