Lowering cholesterol levels
HIGH levels of cholesterol are one of the major causes of heart disease and stroke. This condition may be caused by a variety of factors, including genetics, diet, and lifestyle.
But recent studies show that several natural food components do help lower cholesterol levels effectively. Here are some examples:
Plant sterols
Plant sterols (also known as phytosterols or plant stanols) are naturally occurring compounds found in plants that possess cholesterol-lowering properties. They are cholesterol absorption inhibitors and act by reducing the amount of cholesterol absorbed via the intestines.
Plant sterols have been shown to reduce cholesterol in human subjects by 10% to 15%, and are therefore, increasingly added to health foods to help lower blood cholesterol levels. The US Food and Drug Administration (FDA) has established that a total daily intake of at least 0.8 grams of plant sterols may reduce the risk of heart disease.
Oats
Oats contain soluble fibre called “beta glucans” which lower bad LDL cholesterol. The high content of soluble fibre, complex carbohydrates and protein in oats also stabilises blood-glucose levels.
Omega 3 fish oil
Omega 3 fatty acids are essential unsaturated fatty acids that cannot be synthesised by the human body, but are vital for normal metabolism. Omega 3 fish oils contain eicosapentaenoic acid (EPA), and docosahexaenoicacid (DHA), which are polyunsaturated fatty acids that are known to reduce inflammation throughout the body, along with other health benefits.
The US National Institutes of Health (NIH) published a list of three medical conditions for which omega 3 fish oils are highly recommended. These three conditions are hypertriglyceridaemia (high blood triglyceride levels), secondary cardiovascular disease, and hypertension (high blood pressure).
The American Heart Association also recommends the daily consumption of fish oil for patients with coronary heart disease.
Psyllium husk
Psyllium husk, also known as ispaghula husk, is a widely used source of soluble dietary fibre that is not absorbed via the small intestine. Psyllium husk, once ingested, works by absorbing excess water, subsequently softening the stools, and thereby, stimulating bowel elimination.
Psyllium husk is commonly used to relieve constipation, irritable bowel syndrome and also to improve and maintain regular gastrointestinal transit.
Recent research has also shown psyllium husk to be helpful in lowering cholesterol and controlling diabetes.
The American Journal of Clinical Nutrition has published research concluding that the use of soluble fibre cereals is an effective part of a prudent diet for the treatment of mild to moderately high cholesterol levels.
Research also indicates that psyllium incorporated into food products is effective at reducing blood glucose response.
The FDA has established a beneficial correlation where psyllium husk intake is associated with a decreased risk of coronary heart disease.
It has been found that psyllium’s soluble fibre, in conjunction with a diet low in cholesterol and saturated fat, has the potential to reduce risk of coronary heart disease by decreasing the blood cholesterol levels.
