Cancer Benefits From Olive Oil

Many medical researchers believe cancers of the colon, prostate, and breast are linked to dietary fat intake. Typically, high-fat diets were blamed, but research is beginning to suggest the more important factor may be the type of fat in the diet. In Spain, Italy, and Greece, where olive oil is used in most households, cancer incidence is much lower than in northern Europe and the United States, where olive oil use isn't as widespread.

There is reason to believe that olive oil
can help prevent breast cancer.

There is plenty of controversy regarding whether olive oil can play any part in helping to prevent breast cancer, but women who follow a Mediterranean-style diet appear to have a lower risk of the disease.

A study published in the March 2005 issue of the Annals of Oncology showed that oleic acid, the principal monounsaturated fat in olive oil, dramatically decreased the growth of aggressive forms of breast tumors in test tubes. When oleic acid was combined with the commonly used breast cancer drug Herceptin, the effectiveness of the drug was vastly improved.

A review of studies conducted between 1990 and 2003 that was presented in the July 2005 issue of the World Journal of Surgical Oncology noted a direct association between saturated fat intake and breast cancer incidence.

The more saturated fat consumed, the higher the incidence of breast cancer. In addition, the researchers reported an inverse relationship between the disease and oleic acid: The more oleic acid a woman ate, the lower her risk of breast cancer.

On the other hand, a different meta-analysis, published in the September 2004 International Journal of Cancer, analyzed ten studies that involved more than 2,000 cases of breast cancer. It found opposite results -- the more oleic acid consumed, the higher the rate of breast cancer.

Clearly, more studies are needed to determine olive oil's real relationship to breast cancer. In the meantime, moderation may be the key to reaping the benefits of olive oil without increasing risk.

Research also suggests that olive oil is effective against diabetes. The next page explains the benefits of switching to olive oil instead of switching to a low-carbohydrate diet.
