Does Olive Oil Reduce Cholesterol?
As we noticed above, olive oil’s composition is such that the healthy fatty acids exceed the unhealthy fatty acids. Due to high cholesterol level, the harmful fats can accumulate in coronary arteries which supply blood to the heart, thus resulting in their blockage. In this situation, heart would have to exert more in order to provide blood to every cell. This puts pressure on arteries, resulting in hypertension i.e. high blood pressure and some serious heart diseases.
Olive oil in your diet helps in reducing your cholesterol level. The monounsaturated fatty acids in olive oil are useful in reducing overall cholesterol level and the proportion of low density lipoprotein in body. Moreover, unlike polyunsaturated fatty acids, the monounsaturated fatty acids do not lower the level of high density lipoproteins which are suitable for our body. So we can say, olive oil has dual effects of increasing proportion of healthy fats and decreasing the proportion of unwanted unhealthy fats from body. However, one must keep in mind that if olive oil is used with items containing saturated fats, it would not help in reducing bad fat content. So in order to get the most out of the olive oil, it needs to replace unhealthy fat.
The usefulness of olive oil for healthy heart can be judged from the fact that Food and Drug Administration has permitted the olive oil producers to mention on the label that it is proved through some evidence that the use of two spoons olive oil daily can help reduce the risk of coronary heart disease because of the presence of monounsaturated fat in it.
Despite all the above mentioned benefits, you need to keep in mind that olive oil does contain a small amount of calories as are also found in other oils. So you need to be careful about the quantity you use. If you are prone to coronary artery disease due to high fats, it would be a wise decision to replace unhealthy fats with healthy dietary fats by using use olive oil for healthy heart.
