Cholesterol is not a deadly poison, but a substance vital to the cells of all mammals. It is a type of fat which is produced by the liver and is crucial for normal body function. 

Cholesterol exists in the outer layer of every cell in our body and has many functions. It is essential for determining which molecules can pass into the cell and which cannot. It is involved in the production of sex hormones, to name a few. 

There is no such things as good or bad cholesterol, but mental stress, physical activity and change of body weight which is cause by other factors may influence the level of blood cholesterol. A high cholesterol is not dangerous by itself, but may reflect an unhealthy condition, or it may be totally innocent. A high blood cholesterol is said to promote atherosclerosis and thus also coronary heart disease but many studies have shown that people whose blood cholesterol is low become just as atherosclerotic as people whose cholesterol is high. So basically if a person is diagnosed with high blood cholesterol, there’s an underlying situation which is causing this and it would need to be found and addressed. 

I have found that a very common cause is too much simple carbs in the diet. The cycle is this - Let’s say you eat sugar or white bread (which turns into sugar quickly and get into your blood rapidly). The body is thrown into an emergency handling to reduce the quantity of sugar that was just thrown into circulation because too much sugar in the blood can be lethal. Our body is regularly monitoring the level of sugar to keep it within a certain range (we call it sugar regulation). When it peaks above the maximum range after eating something sweet, the pancreas gets into action  to reduce the level back into normal range by producing insulin. Insulin handles the sugar, some of the sugar gets used by the brain, some by the muscles but the surplus is turned into fat for use later on. Insulin is irritating to the arteries, so if this is a regular occurrence with someone who eats chocolate every day let’s say, then the walls of the arteries get very irritated, often inflammaed and weak so cholesterol gets produces to reinforce the cells in the wall and patch the arteries so they do not burst. Over time you can get a build up of cholesterol or fat deposit in the arteries which reduces the flow of blood through the arteries and causes high blood pressure. You see where this is leading. So a lot can be done with proper nutrition.
