It is a fatty substance that is made in the body, in the liver. It is often portrayed as the villain. It is very important for our body to function properly. Cholesterol is found in the food we eat but we do not know how much of it is produced by what food.The liver makes, packages and distributes cholesterol around the body as and when it’s needed. Even you eat salads or live on low fat food still you would make cholesterol as it is very important to function properly.Cholesterol travels around the body as lipoproteins (made up of fats and proteins). There are 2 types of lipoproteins. Low Density Lipoproteins (LDL) and High Density Lipoproteins (HDL). HDL is the good cholesterol and Ldl is the bad cholesterol. LDL leads to the heart attacks and stroke and whereas HDL prevents all this diseases.
Saturated Fat: You should avoid the saturated fats to prevent high cholesterol disease as too much of it contribute to the increase in LDL cholesterol and also raises the amount of blood fats in the body. These fats are also associated with the risk of diabetes and fatty liver disease.
Trans Fat: These increase the bad LDL cholesterol and triglycerides whilst lowering good HDL and this ratio of fats is considered to be the most damaging to health. Trans fats are artificially produced when vegetables fats are hydrogenated(turned from a liquid to solid). Its good to check food labels so you can avoid eating trans fats.
Eating foods naturally high in saturated fat, such as fatty meats, utter and other full fat diary foods, may not be detrimental to your health. However, it is worth remembering that processed foods high in saturated fat often co-exist with sugar and salt, which when eaten in excess are bad for your health.
