Olive Oil vs. Coconut Oil. The olive tree is an important ancient tree in Greece. It was consider a symbol of peace, fertility and victory. It also plays an important role in the Mediterranean diet due to its nutritional and health benefits. Clinical studies support that theory especially in the prevention of cardiovascular diseases. Studies also shows that olive oil has a low content of polyunsaturated fatty acids and a high content of monounsaturated fatty acids, reducing the risk factors associated with cardiovascular disease by controlling the lipoprotein profile, blood pressure, glucose metabolism, and antithrombotic profile  Coconut oil is about 90 percent saturated fat and high levels of saturated in the diet are unhealthy because it raises LDL cholesterol levels. However, research also showed that coconut oil also raises HDL levels up. Coconut oil contained lauric acid in higher amounts more than any other vegetable oil. This explained its HDL effects in the body.
