Healthy Heart Benefits
Atherosclerosis, also called hardening of the arteries, occurs when particles of LDL cholesterol stick to the walls of the arteries. Eventually these particles build up and form plaque. This plaque narrows the blood vessels and increases the work load of the heart in an effort to get oxygenated blood to the entire body. The result can be a heart attack or stroke.
Olive oil is rich in monounsaturated fat and antioxidants like chlorophyll, carotenoids and vitamin E. Scientists have identified a compound in olive oil called oleuropein which prevents the LDL cholesterol from oxidizing. It is the oxidized cholesterol that sticks to the walls of the arteries and forms plaque. Replacing other fats in your diet with olive oil can significantly lower blood pressure and reduce the risk of heart attack.
A study published in the January 2005 issue of Annals of Oncology has identified oleic acid, a monounsaturated fatty acid found in olive oil, as having the ability to reduce the affect of an oncogene (a gene that will turn a host cell into a cancer cell). This particular oncogene is associated with the rapid growth of breast cancer tumors. The conclusion of the researchers was that oleic acid when combined with drug therapy encouraged the self-destruction of aggressive, treatment-resistant cancer cells thus destroying the cancer. Olive oil has been positively indicated in studies on prostate and endometrial cancers as well.
Unlike other fats, which are associated with a higher risk of colon cancer, olive oil helps protect the cells of the colon from carcinogens. A study published in the November 2003 issue of Food Chemistry Toxicology suggests that the antioxidants in olive oil reduce the amount of carcinogens formed when meat is cooked.
Blood Sugar Controller
Diabetics or those at risk for diabetes are advised to combine a low-fat, high-carbohydrate diet with olive oil. Studies show this combination is superior at controlling blood sugar levels compared to a diet that consists entirely of low-fat meals. Adding olive oil is also linked to lower triglyceride levels. Many diabetics live with high triglyceride levels which put them at risk for heart disease.
The body uses the healthy fats in olive oil to produce natural anti-inflammatory agents. These anti-inflammatory agents can help reduce the severity of both arthritis and asthma. Uninflamed cell membranes are more fluid and better able to move healthy nutrients into the cells and move waste products out. A lower incidence of osteoporosis and dementia is found in areas where people consume large quantities of olive oil.
A Fat That Helps You Lose Fat
Sounds impossible, right? A study conducted on eight over-weight men published in the September 2003 issue of the British Journal of Nutrition yielded results that indicate a significant loss of body weight and fat mass can be achieved without increasing physical activity and making only one change in eating habits: the substitution of olive oil for saturated fats.
The eight men were divided into two groups and for four weeks ate similar foods with the exception that the first group ate more saturated than unsaturated fats. The second group consumed the same number of calories as the first group, but the fats were mostly monounsaturated fat (olive oil). At the end of four weeks, the men from the second group were lighter and had a lower body-fat index than the men who ate the saturated fats.
