What is cholesterol?
Cholesterol is a wax-like substance that is produced in the body by all cells. It is an essential building block in the human body and plays a key role in many metabolic processes, including maintaining cells and production of hormones. Your body makes all the cholesterol it needs, so we don’t need to add it in through our diets as well!Studies have shown, convincingly, that there is a very strong association between cholesterol levels and a healthy heart, along with other lifestyle factors such as overall diet, high blood pressure, weight and activity levels.Back to top What are the two types of cholesterol?
There are two types of cholesterol:- LDL or "Bad" cholesterol which is the main cause of narrowing of the blood vessels when it is elevated.
- HDL or "Good" cholesterol that actually works to clear cholesterol from cells.
While our bodies need cholesterol, if there is too much cholesterol in the blood, it can build up in the walls of our arteries causing narrowing of the blood vessels, which may then become a problem for heart health.Lowering our bad “LDL” cholesterol by simple dietary changes helps manage your heart health. Too much bad fat (saturated and trans fat) can increase LDL cholesterol. Replacing bad fats (saturated and trans fats found in processed meats and fried foods) with good fats (polyunsaturated and monounsaturated fats found in nuts and avocados), for example, can help manage your cholesterol.The only way of knowing your cholesterol levels is to have a blood test. Ask your GP to have your cholesterol tested and discuss what your results mean for you. For more specific dietary advice on cholesterol management, speak to a Dietitian. Another great place to go for information is the Heart Foundation website.Back to top What should I do if I'm worried about my cholesterol?
If you have any concerns about your cholesterol level or heart health, always contact your GP. For more specific dietary advice on cholesterol management, speak to an Accredited Practising Dietitian (APD).

Adopting a diet that emphasises a variety of vegetables, fruits, legumes, including soy, wholegrain cereals and breads, nuts and seeds, soluble fibre and healthy fats every day are important to help manage your heart health. Other healthy lifestyle factors; such as not smoking, maintaining an active lifestyle and healthy weight, are also important.By nourishing your body through good food and exercise, you can make a difference to your health. The most effective cholesterol lowering dietary strategies are to replace bad fats (saturated and trans fats found in processed meats and fried foods) with good fats (polyunsaturated and monounsaturated fats found in nuts and avocados) and by increasing your intake of plant sterols each day, as part of a healthy diet. These two strategies account for the majority of the cholesterol lowering effect that is achievable through diet. The effects of plant sterols from enriched foods are additive to those of a healthy diet. So in combination, plant sterols and choosing healthy fats in place of saturated fat have the potential to lower LDL cholesterol by about 15%^. With even further benefits to cholesterol lowering by adopting healthy plant-based foods. For our top 12 tips, click here.^Ras, R.T., J.M. Geleijnse, and E.A.

What are plant sterols?
Plant sterols (also known as phytosterols) are substances that can help lower your cholesterol. They are found naturally in very small amounts in a variety of plant foods such as grains, vegetables, fruit, legumes, nuts and seeds. Only small amounts can be obtained through our diets, so enriched foods are needed to help us achieve an effective intake of plant sterols that will lower high cholesterol.
When consumed, plant sterols reduce the absorption of cholesterol from your intestines into the body. This includes both the cholesterol you eat (called dietary cholesterol) and that made by your liver, which enters the intestines through bile.
Based on many clinical studies (over 120 studies), the effective dose of plant sterols from enriched foods has been identified as 2-3 grams per day. The evidence shows that the cholesterol lowering effect of plant sterols starts to plateau between 2 and 3 grams per day, and consuming in excess of this 3 grams per day doesn’t provides further benefits. Based on the evidence, heart health authorities globally, including the Australian Heart Foundation, British Heart Foundation and the European Society of Cardiology recommend people with high cholesterol eat 2-3 grams of plant sterols each day to lower elevated LDL cholesterol.

Where else can I get plant sterols in my diet? Can I get enough in my diet?
The amount of plant sterols naturally occurring (not fortified) in plant foods is very small. For example, to get 2 grams of plant sterols from a kiwi fruit, you would need to consume 500kg! The intake of naturally occurring plant sterols in the diet is small and estimated to be less than half a gram. We are unable to meet the recommended 2-3 grams of plant sterols daily, which is needed to lower cholesterol, from our diets, even with lots of plant foods. Therefore, plant sterol-fortified or enriched products provide an effective way to boost our plant sterol intakes and meet required levels in order to achieve benefits of cholesterol lowering.Back to top How does the benefits of plant sterols compare to beta glucan in oats and barley?
For plant sterols to effectively reduce cholesterol, 2-3g of plant sterols are required daily. For beta-glucan to effectively reduce cholesterol, 3g of beta-glucan is required daily.Beta-glucan is found naturally in nutritious grains of oats and barley. 2g of plant sterols can be eaten in 2 Weet-Bix Cholesterol Lowering (1 serve), whereas to get an effective dose of 3 grams of beta-glucan from oats per day requires the consumption of 3 serves/bowls of oats, as one 40 gram serve of oats contains approximately 1g of beta-glucan. In addition, plant sterols are more effective at lowering cholesterol than beta-glucan, with 2g per day of plant sterols clinically proven to lower LDL cholesterol by up to 9%, whereas 3g of beta-glucan lowers LDL cholesterol by up to 7.4%^.^European Food Safety Authority (EFSA), Scientific Opinion on the substantiation of a health claim related to oat beta-glucan and lowering blood cholesterol and reduced risk of (coronary) heart disease pursuant to Article 14 of Regulation (EC) No 1924/2006, EFSA Journal 2010;8(12):1885.
Back to top How are plant sterols added to Weet-Bix™ Cholesterol Lowering?
Weet-Bix™ Cholesterol Lowering biscuits are regular Weet-Bix with plant sterols added after the biscuits have been toasted. The plant sterol ingredient is placed in the centre of the biscuit while the plant sterols are in a liquid form, where it is largely absorbed into the flakes in that area of the biscuit. If you were curious and split a bix in half, you will find some patches of darker flakes and may see what looks like an oily residue. Don't worry, this is the active ingredient!Back to top How does Weet-Bix™ Cholesterol Lowering work?
Weet-Bix™ Cholesterol Lowering helps lower cholesterol by the action of added plant sterols. Plant sterols (or phytosterols) are found naturally in very small quantities in a variety of plant foods such as grains, vegetables, fruit, legumes, nuts and seeds. They are clinically proven to actively lower cholesterol by partially blocking the absorption of cholesterol in the digestive system. Plant sterols and cholesterol have a similar chemical structure – because of this, both molecules compete for absorption in the small intestine. Plant sterols actually stop some cholesterol from being absorbed into the blood steam. The Heart Foundation recommends 2-3 grams of plant sterols daily.2 grams of plant sterols consumed on a daily basis from plant sterols enriched foods is proven to lower cholesterol by up to 9%.To be sure that Weet-Bix™ Cholesterol Lowering is as effective as all the science around plant sterols, ÄűĂʵĽş˝ ran a trial with Professor Peter Clifton, Professor of Nutrition at the University of South Australia. This trial showed that cholesterol was effectively reduced by up to 9% within 4 weeks. The study supported Weet-Bix™ Cholesterol Lowering as being an effective, easy and nutritious food for people who need to manage their cholesterol.Back to top How much plant sterols are in a serve of Weet-Bix™ Cholesterol Lowering? Is this enough to work?
Eating just 1 serve, which is 2 Weet-Bix™ Cholesterol Lowering biscuits provides you with 2 grams of plant sterols. 2 grams of plant sterols consumed on a daily basis from plant sterols enriched foods is proven to lower cholesterol by up to 9% within 4 weeks as part of a healthy diet low in saturated fat. The Heart Foundation recommends 2-3 grams of plant sterols daily.Back to top
