Have you had your cholesterol checked?
More people die in Ireland today from heart disease than any other illness. It accounts for 36% of deaths in Ireland. The positive news is that 80% of the incidence of heart disease can be prevented by improving lifestyle factors. Unfortunately, we are not in control of other risk factors such as age, gender and genetic predisposition to illness. We are however in control of modifiable risk factors such as cholesterol, blood pressure and smoking and if taken care of we can reduce the risk of developing heart disease.
Get your cholesterol and blood pressure checked!
Cholesterol is a waxy substance of which 75% is produced by the liver and 25% can be found in certain foods.
It is essential in producing all the body’s cells and hormones, and is needed to make vitamin D and bile for digestion. However, when your blood has too much cholesterol this can stick to the walls of arteries. A build-up of cholesterol in the arteries, narrows the arteries restricting the amount of blood flow to the brain and heart. This can eventually cause a blockage leading to a heart attack or stroke.
Cholesterol is carried in the blood attached to proteins called lipoproteins. There are two main lipoproteins: LDL (low density lipoprotein) and HDL (high density lipoprotein). Too much LDL is unhealthy therefore it is referred to as bad cholesterol and should be kept low. HDL is protective however and helps to remove LDL cholesterol. HDL is known as the good cholesterol and should be kept high.
What do the numbers mean?
One of the best ways of taking control of your cholesterol is through a healthy diet and physical activity.
Choosing a healthy diet low in saturated fat (butter, cream, cheese, coconut oil, palm oil, lard, fatty meat, processed meats, confectionary foods) is one way of reducing your cholesterol levels. Aim to consume less than 20g saturated fat per day to help to reduce your LDL cholesterol. When reading food-labels avoid anything more than 5g saturated fat per 100g.
It’s not all about cutting out the bad stuff – the good news is that there are foods you can introduce into your diet that will also help to lower your cholesterol levels.
- Nuts – with their positive nutrient profile of fibre, falvonoids and monounsaturated fats, have been shown to lower cholesterol by 3-7.5%. They reduce the risk of heart disease by 37% . Aim for 30g unsalted almonds, pecans, pistachios, walnuts or peanuts per day.
- Soluble fibre – found in fruit, vegetables, oats, beans and pulses. It can lower LDL cholesterol by 5-20% if you consume 15-20g per day. Increase foods containing oat beta – glucan (porridge, oatbran, oatcakes, porridge bread) and other wholegrains, beans and pulses (aim for 80-100g per day).
- Oil rich fish – a rich source of unsaturated fats especially omega 3 which have heart protective benefits. Aim to have 1-2 servings (140g) per week – salmon, sardines, mackerel, kipper, trout, anchovies, eel, pilchards, fresh tuna, sprats, whitebait, whiting. Other healthy fats include olive oil, rapeseed oil, sunflower oil, corn oil, avocado, olives, nuts and seeds.
- As always recommended, increase your fruit and vegetables to 5-7 portions per day. A portion is approximately 80g per day. Consumption of at least 400g fruit and vegetables per day has been associated with lower incidence of heart disease, high cholesterol, high blood pressure, cancer and obesity. They are low in calories, high in phytonutrients, soluble fibre, antioxidants and vitamins and minerals.
- Plant stanols or sterols are structurally similar to cholesterol and are naturally found in a wide range of foods such as nuts, seeds, vegetable oils, whole grains, fruits and vegetables. They mimic cholesterol and compete with it for absorption. Most diets provide a small amount of plant stanols/sterols (approx 300mg for average person, or 600mg for those on vegetarian diets) however an intake of 1.5-2.4g per day has been shown to reduce cholesterol by 7-10% over 2-3 weeks. Always check with your GP if you are taking medication for your cholesterol.
- Soya foods – consumption of 15g-25g soya protein daily has been scientifically proven to lower LDL cholesterol by 4-10%. Include more soya products in the diet such as soya beans, soya yoghurts, soya milk, tofu, edamame beans.
