• What’s wrong with having high cholesterol?
– Major risk factor for cardiovascular disease
– Higher the cholesterol higher the risk
– Clogs the arteries and therefore reduces blood
flow to the heart, brain and other tissues
– Bigger concern in the presence of other risk
factors (obesity, inactivity, diabetes, hypertension,
smoking)
What is Cholesterol?
![Page 3: LOWERING YOUR CHOLESTEROL & BLOOD PRESSURE](https://reader030.fdocuments.in/reader030/viewer/2022012804/61bd26b461276e740b0fe23a/html5/thumbnails/3.jpg)
What is Cholesterol?
• It is a type of fat that is part of all animal cells and is essential for life
The body uses it to:
• Build the structure of cell membranes
• Make hormones like oestrogen, testosterone and adrenaline
• Help the metabolism work efficiently; for example, cholesterol is essential for the body to produce vitamin D
• Produce bile acids, which help the body digest fat and absorb important nutrients

Cholesterol Transportation
The body transports cholesterol to the cells via
two main methods:
1. Low-density lipoprotein (LDL) – often called
the ‘bad’ cholesterol because it transports
cholesterol to the heart and major arteries
2. High-density lipoprotein (HDL) – often called
the ‘good’ cholesterol as it takes the surplus
cholesterol away from the tissues and
transports it for disposal.
The body produces it’s own cholesterol so there is no need to consume it in our diet.

Effects of High Cholesterol!
• The liver is the main processing centre for cholesterol
• When we eat animal fats, the liver returns the excess cholesterol back into our bloodstream
• When there is too much cholesterol circulating in our bloodstream, it can build up into fatty deposits
• These deposits cause the arteries to narrow and can eventually block the arteries completely, leading to heart disease and stroke.

Avoiding High Cholesterol!
Cholesterol in food is only found in animal products.
Limit foods high in saturated fats including:
• Fatty meats
• Full fat dairy products
• Processed meats like salami and sausages
• Snack foods like chips
• Most takeaway foods, especially deep fried foods
• Cakes, biscuits and pastries
Saturated fat increase your body’s production of LDL cholesterol.

Reduce High Cholesterol Through Your Diet!
• Increase your intake of fresh fruit, vegetables, soluble fibre and wholegrain foods you have each day. They should make up the main component of your meals.
• Choose low or reduced fat milk, yoghurt and other dairy products or have 'added calcium' soy drinks.
• Choose lean meat limiting fatty meats (remove the skin from chicken and trim any visible fat)
• Have fish (fresh or canned) at least twice a week.
• Replace butter and dairy blends with polyunsaturated margarines
• Use a variety of oils for cooking – eg sunflower, canola and soybean oils

• Include nuts (unsalted), legumes and seeds.
• Limit cheese and ice-cream to twice a week.
• Limit take-away foods to once a week
• Limit snack foods like potato and corn chips to once per week
• Reduce cholesterol rich foods such as egg yolks, liver, kidney and brains!!!
• Limit cakes, pastries and chocolate to once per week

Increase your Exercise
• Exercise assists in the production of HDL
cholesterol and therefore reduces LDL
levels.
• Aim for 30 minutes of moderate intensity
exercise on most days of the week
• Combine cardiovascular (aerobic) exercise
with resistance (weight training, body-
weight exercises) exercise.
• Moderate Intensity = 60% - 80% max HR

Medications
• Your GP can recommend if a cholesterol lowering
medication is necessary to assist in the management of
high cholesterol.
• These medications are very effective at lowering
cholesterol and therefore lowering the risk of
cardiovascular disease.

Blood Pressure
What is Blood Pressure?
• It is the pressure of the blood in the arteries as
the heart pumps it around the body
• Systolic blood pressure - the pressure in the
arteries as the heart squeezes out blood during
each beat
• Diastolic blood pressure - the pressure as the
heart relaxes before the next beat
![Page 13: LOWERING YOUR CHOLESTEROL & BLOOD PRESSURE](https://reader030.fdocuments.in/reader030/viewer/2022012804/61bd26b461276e740b0fe23a/html5/thumbnails/13.jpg)
Blood Pressure
What are the norms?
• Normal blood pressure: less than 120/80
• High normal: between 120/80 and 140/90.
• High: 140/90 or above.
• Very high: 180/110 or above.
Important to remember that blood pressure is always
changing to meet your body’s needs
