October is National Cholesterol Month.\u00a0 Heart UK sponsors this initiative and the aim is to increase people\u2019s knowledge of what cholesterol is and how everyone can adjust their lifestyle to improve their chances of having a healthy cholesterol level.\u00a0 Healthy cholesterol levels are necessary to protect against developing serious, life shortening diseases.\u00a0 The challenge this year has been to do 100 miles of exercise across the month.\u00a0 This is because engaging in exercise can have a very positive effect on increasing good cholesterol levels; in fact, research has shown that just sweating during exercise can have a beneficial physiological effect in this way.\u00a0 This surprises many people because they tend to think that managing cholesterol levels is all about diet and taking medication.<\/p>\n
Cholesterol is a fat, also known as a lipid.\u00a0 It is made in the liver.\u00a0 Cholesterol is used in the body to repair cell damage; in fact, it is in every cell in the body and it is necessary for it to be there.\u00a0 The cholesterol found in cells is not harmful to the body in any way.\u00a0 It is circulated round the body to where it is required by lipid carriers called Low Density Lipoproteins (LDL).\u00a0 If the level of LDL circulating in the blood exceeds what the body needs it collects on the walls of the blood vessels and forms lumps called plaques.\u00a0 When the plaques grow large, they can break which encourages the formation of blood clots round them.\u00a0 If a large clot develops that totally blocks a blood vessel, this will lead to serious disease, such as a heart attack, or stroke, or other cardiovascular problems.<\/p>\n
Sometimes, abnormally high cholesterol is due to genetics; this is called Familial Hypercholesterolaemia.\u00a0 However, it is more common for raised cholesterol to stem from poorly managed lifestyle factors.\u00a0 Sedentary lifestyles which are prevalent in modern society are a major cause of this.\u00a0 Exercise creates another lipid carrier, High Density Lipoprotein (HDL) which mops up and clears LDL from the bloodstream which it then carries back to the liver for processing and elimination.\u00a0 That is the reason that Heart UK is emphasising the importance of exercise to assist with managing cholesterol levels.<\/p>\n
There is a third type of cholesterol called triglycerides; this comes from fat that we eat in our food.\u00a0 If we have a diet that is over rich in saturated fats this can lead to unhealthy levels of triglycerides in the body which also leads to cardiovascular disease.\u00a0\u00a0 That is how keeping to a healthy diet which is low in saturated fats can lead to better health.\u00a0 See the British Dietetic Association article below for more information on cholesterol and diet.<\/p>\n
