Cholesterol
• It is a principle sterol (alcohol and steroid)
• An organic molecule, white, insoluble, soft and waxy
substance
• Found in bloodstream and body’s cells.
Movement Of Cholesterol
• Cholesterol moves in the form of lipoproteins in
blood
Two types of Lipoproteins
• High-Density Lipoproteins (HDL)
• Low-Density Lipoproteins (LDL)
Cholesterol in Foods
• Animal products contain cholesterol itself
• As liver is involved in its production.
Significance
Body uses cholesterol for following functions:
• For normal cell growth and tissue repair.
• Building the structure of cell membranes.
• Necessary for the absorption of fat-soluble vitamins
(A, D, E and K) from food.
Cont..
• Essential to produce vitamin D
• Make digestive bile acids in intestine.
• Maintain neurotransmitter and brain function
• Precursor for biosynthesis of steroid hormones
Cholesterol Level
Total Cholesterol Level= LDL+HDL+ 20% triglycerides
What affects Cholesterol level?
• Diet
• Weight
• Physical activity
• Smoking
Reason of High Cholesterol Level
• Poor diet
• Diabetes
• Obesity
• Lack of exercise
• Alcohol Consumption
Poor Diet
• Eating saturated fat present in animal products
• Trans fats
• Dairy products
• Red meat
Complications
• High cholesterol level causes an accumulation of
plaque in arteries leading to arteriosclerosis, which
can further lead to:
• Chest Pain (angina)
• Heart Attack
• Stroke
Dietary Tips to avoid cholesterol
• Eating lots of healthy foods, such as fibrous whole
grains
• Foods high in omega-3 fatty acids
• Limiting intake of partially hydrogenated oils and
fried foods,
• Protein-rich and fibrous plant sources, including
beans in the diet.
