Lower Cholesterol Challenges
What is Cholesterol?
Cholesterol is a lipid (fat) which is produced by the liver. Cholesterol is vital for normal body function. Every cell in our body has cholesterol in its outer layer.
What are the functions of cholesterol?
- Cholesterol builds and maintains cell membranes, it prevents crystallization of hydrocarbons in the membrane
- Cholesterol is essential for determining which molecules can pass into the cell and which cannot
- Cholesterol is involved in the production of sex hormones (androgens and estrogens)
- Cholesterol is essential for the production of hormones released by the adrenal glands
- Cholesterol aids in the production of bile
- Cholesterol converts sunshine to vitamin D
- Cholesterol is important for the metabolism of fat soluble vitamins, including vitamins A, D, E, and K
- Cholesterol insulates nerve fibers
Possible High Cholesterol Levels Problems
- Atherosclerosis – narrowing of the arteries.
- Higher coronary heart disease risk – an abnormality of the arteries that supply blood and oxygen to the heart.
- Heart attack – occurs when the supply of blood and oxygen to an area of heart muscle is blocked, usually by a clot in a coronary artery. This causes your heart muscle to die.
- Angina – chest pain or discomfort that occurs when your heart muscle does not get enough blood.
- Other cardiovascular conditions – diseases of the heart and blood vessels.
- Stroke - occurs when a blood clot blocks an artery or vein, interrupting the flow to an area of the brain. Can also occur when a blood vessel breaks. Brain cells begin to die.
High Cholesterol Causes - Lifestyle
- Nutrition - although some foods contain cholesterol, such as eggs, kidneys, eggs and some seafoods, dietary cholesterol does not have much of an impact in human blood cholesterol levels. However, saturated fats do! Foods high in saturated fats include red meat, some pies, sausages, hard cheese, lard, pastry, cakes, most biscuits, and cream.
- Sedentary lifestyle - people who do not exercise and spend most of their time sitting/lying down have significantly higher levels of LDL (bad cholesterol) and lower levels of HDL (good cholesterol).
- Bodyweight - people who are overweight/obese are much more likely to have higher LDL levels and lower HDL levels, compared to people who are of normal weight.
- Smoking - this can have quite a considerable effect on LDL levels.
- Alcohol - people who consume too much alcohol regularly, generally have much higher levels of LDL and much lower levels of HDL, compared to people who abstain or those who drink in moderation.
