Cholesterol has a very important function in our body: it is essential for the normal development of the brain and for the synthesis of certain hormones. In short, cholesterol itself is an ally.
It only becomes an enemy when it is found in excess in our bodies. There are two types of cholesterol, the 'good' (formally known as HDL cholesterol), and the bad (known as LDL). Having high 'bad' cholesterol is one of the main risk factors for suffering a myocardial infarction.
