New International Olive Council Report Underscores Health Benefits of Table Olives, Olive Oil

By admin Posted in: News on March 22nd, 2012

The first in a series of reports scheduled to be published by the International Olive Council (IOC) over the next year, “Health Benefits of Olives and Olive Oil” indicates that consumers are increasingly seeking to incorporate foods into their diets that can help boost or maintain health, as well as prevent some diseases.

Olives and Olive oil are the most common sources of dietary fat in a Mediterranean diet, and offer many unique and powerful health-promoting effects. Click here to view the full report.

Below is a preview of key findings:

Cardiovascular Disease

  • Olive oil reduces low density lipoprotein (LDL, or “bad”) cholesterol without decrease of HDL (or “good”) cholesterol and improves many additional risk factors for cardiovascular disease, including blood pressure, glucose metabolism and antithrombotic profile (helps protect against blood clots).
  • Olive oil can also positively change endothelial function (blood flow), inflammation and oxidative stress, which can play a role in atherosclerosis and increase risk of heart attack or stroke.
  • Since 2004, the Food and Drug Administration (FDA) announced the availability of a qualified health claim for monounsaturated fatty acids from olive oil and reduced risk of coronary heart disease. “Limited and not conclusive scientific evidence suggests that eating about 2 tablespoons (23 grams) of olive oil daily may reduce the risk of coronary heart disease due to the monounsaturated fat in olive oil.”

Diabetes

  • Clinical studies support the positive effect of olive oil on diabetes: a study of 418 people showed that a Mediterranean diet rich in olive oil reduced diabetes by nearly 50 percent compared to low-fat diets.

Stroke

  • Data from the Three Cities Study found that elderly people who consume olive oil daily have fewer strokes than those who do not. After five years, there were 148 incidents of stroke among the 7,625 study participants. Those who were “intensive” users of olive oil (using it for both cooking and as a dressing) had a 41 percent lower risk of stroke compared to those who did not use olive oil at all.1

Hydroxytyrosol and Heart Health

  • The European Food Safety Authority (EFSA) recently approved a “heart health” claim for hydroxytyrosol. This phytochemical and related polyphenol compounds from olives and olive oil offer protection to blood lipids from oxidative damage.2

Cancer

  • Studies have found that excessive saturated and trans fat consumption cause cancer, and also concluded that there are clear associations between reduced rates of certain types of cancer and increased olive oil consumption.3
  • The oleic acid in olive oil has been found to be particularly effective against breast, colon and prostate cancer. Eating a Mediterranean Diet could prevent up to 25 percent of colon; 15 percent of breast; and 10 percent of prostate, pancreas and endometrial cancers.4

Inflammation

  • The Mediterranean diet in general and olives and olive oil in particular have many anti-inflammatory properties. For example, increased olive oil consumption has been linked to a decreased risk of developing rheumatoid arthritis, an autoimmune disease characterized by inflammation and pain, particularly in the joints.5
