A fact about cholesterol is that it is an essential part of every cell in the body. Only about one-third of total cholesterol is needed through our diet whereas almost two-thirds of the cholesterol is produced by the body (in the liver). High levels of ‘LDL cholesterol’ (Bad cholesterol) are associated with increased risk of cardiovascular disease, whereas a high level of ‘HDL cholesterol’ (Good cholesterol) is protective.
Research shows that the amount and type of dietary fat consumed can affect blood cholesterol levels. Dietary fat especially saturated and trans fats may raise blood levels of total and LDL cholesterol. Recall that high total blood cholesterol levels and LDL cholesterol levels increase the risk of heart disease, while lower levels reduce risk. Higher levels of HDL cholesterol help lower the risk for heart disease.
In 1984, ‘National Institutes of Health (USA)’ stated: It has been established beyond a reasonable doubt that lowering elevated LDL cholesterol, will reduce the risk of heart attacks caused by coronary heart disease. However, there are some groups who dispute the cholesterol lipid hypothesis. In 2015, a paper stated that 92 percent of people with a high cholesterol level lived longer. This caused a lot of buzz on the social media. However, the recent study said that keeping a control on your cholesterol will be beneficial and decrease risk of premature death.
