Mediterranean Diet Reduces Diabetes, Inflammation

Posted on July 22, 2019July 22, 2019 by The Olive Oil Hunter

The following article by Mark L. Fuerst is reprinted from Psychiatric Times, March 31, 2014.

Two new studies show the heart-healthy benefits of eating a Mediterranean diet.

One study linked the diet to a lower risk of diabetes mellitus (DM), especially among those at high risk for cardiovascular disease…

In the first pooled analysis of studies evaluating the possible role of the Mediterranean diet in DM development, adherence to this diet was associated with a 21% reduced risk of DM compared with the control dietary groups. The likelihood of developing DM was almost 27% less in those at high risk for cardiovascular disease than in controls.

“Adherence to the Mediterranean diet may prevent the development of diabetes irrespective of age, sex, race, or culture,” said lead investigator Demosthenes Panagiotakos, PhD, professor at Harokopio University, Athens, Greece. “This diet has a beneficial effect, even in high risk groups, and speaks to the fact that it is never too late to start eating a healthy diet…”

The Mediterranean diet frequently emphasizes fresh fruits and vegetables, whole grains, beans, nuts, fi sh, olive oil, and even a glass of red wine.

Dr. Panagiotakos said he believes the Mediterranean diet lowers the risk of DM by helping guard against obesity. Earlier research has shown that following the traditional Mediterranean diet also is linked to weight loss, a reduced risk of heart disease and related death, and lower blood pressure and blood cholesterol levels…

[In a second study], Italian researchers conducted an analysis of the eating habits of nearly 15,000 healthy Italian men and women aged 35 years or older…

The investigators observed that consumption of the Mediterranean diet was directly related to lower levels of platelets and white blood cells, which, in turn, correlated to lower levels of inflammation [which has been associated with a greater risk of myocardial infarction (heart attack) and stroke].

Why Olive Oil Is So Good for the Heart

Posted on July 22, 2019July 22, 2019 by The Olive Oil Hunter

The following article by Alice. G Walton is reprinted from Forbes, May 20, 2014.

New research in Proceedings of the National Academy of Sciences looks at the effect of the Mediterranean diet on heart health—and the verdict is favorable. But even more than that, the study lays out exactly why olive oil and greens are together so beneficial for the heart.

Until now, researchers hadn’t quite been able to explain why a diet as high in fat as the Mediterranean diet is linked to cardiovascular health. Researchers have wondered what exactly it is about the fats that helps the heart, and now they’ve arrived a pretty convincing mechanism to explain it.

The trick is to create a “fusion” of the healthy fats in, say, olive oil and the nitrites and nitrates in greens like spinach, celery, and carrots, which make up a large part of the Mediterranean diet. This fats–greens pairing, according to the researchers, creates a compound—nitro fatty acid—that has the effect of relaxing blood vessels and bringing down blood pressure, which are key components of heart health.

To test the theory, the team fed mice—with high blood pressure—the omega-6 fatty acids found in olive oil. They also added to their diets sodium nitrite, in order to mimic the pairing of olive oil and veggies. Indeed, not only was the level of nitro fatty acids higher in these mice, but their blood pressure was lower at the end of the 5-day intervention. And when the researchers used a strain of mice that were resistant to the effects of the nitro fatty acids, their blood pressure did not change.

Though the research was done in mice, the mechanism likely applies to people, too. Earlier research has pointed to the benefits of olive oil and nuts on cardiovascular health in humans.

“The findings of our study,” said study author Philip Eaton, “help to explain why previous research has shown that a Mediterranean diet supplemented with extra-virgin olive oil or nuts can reduce the incidence of cardiovascular problems like stroke, heart failure and heart attacks.” Avocados may work too, the team told the BBC, since they also contain healthy unsaturated fats.

Mayo Clinic Recommends Mediterranean Diet as “Heart-Healthy Eating Plan”

Posted on July 22, 2019September 22, 2021 by The Olive Oil Hunter

The following is excerpted from an article published by the Mayo Clinic News Network on November 17, 2014.

If you’re looking for a heart-healthy eating plan, the Mediterranean diet might be right for you. The Mediterranean diet incorporates the basics of healthy eating—plus a splash of flavorful olive oil and perhaps even a glass of red wine—among other components characterizing the traditional cooking style of countries bordering the Mediterranean Sea.

Most healthy diets include fruits, vegetables, fish, and whole grains, and limit unhealthy fats. While these parts of a healthy diet remain tried and true, subtle variations or differences in proportions of certain foods may make a difference in your risk of heart disease.

Benefits of the Mediterranean diet

Research has shown that the traditional Mediterranean diet reduces the risk of heart disease. In fact, an analysis of more than 1.5 million healthy adults demonstrated that following a Mediterranean diet was associated with a reduced risk of death from heart disease and cancer, as well as a reduced incidence of Parkinson’s and Alzheimer’s diseases.

The Dietary Guidelines for Americans recommends the Mediterranean diet as an eating plan that can help promote health and prevent disease. And the Mediterranean diet is one your whole family can follow for good health.

Key components of the Mediterranean diet

The Mediterranean diet emphasizes:

Eating primarily plant-based foods, such as fruits and vegetables, whole grains, legumes, and nuts.
Replacing butter with healthy fats, such as olive oil.
Using herbs and spices instead of salt to flavor foods.
Limiting red meat to no more than a few times a month
Eating fi sh and poultry at least twice a week.
Drinking red wine in moderation (optional).

The diet also recognizes the importance of being physically active and enjoying meals with family and friends.

Compound in Olive Oil Shows Promise in Fight Against Cancer

Posted on July 22, 2019September 22, 2021 by The Olive Oil Hunter

The following is excerpted from an article by Chris Weller, published February 20, 2015, on MedicalDaily.com, based on the results of a recent study conducted by Rutgers University and Hunter College scientists.

Oleocanthal, the primary phenolic compound found in extra virgin olive oil, has been shown to eradicate cancer cells in less than an hour, giving scientists hope that targeted drug options in the future may be possible.

A team of researchers from Rutgers University and Hunter College published their recent study in the journal Molecular & Cellular Oncology. The findings add even more firepower to the argument in favor of olive oil, which has been shown in prior studies to shield our bodies against air pollution, improve our immune systems, protect aging bones, and perhaps even prevent the slide into Alzheimer’s disease….

The study isn’t without its limits. Cell cultures provide a reliable model for understanding how an external substance affects a new biological environment, but cells aren’t as complex as rats, which aren’t as complex as humans. It will still be years before oleocanthal makes its way into a clinical setting, by which time other technologies may have already crowded it out.

As a proof of concept, however, the findings suggest a robust set of possibilities for the compound. Oleocanthal is just one of the many phenols — a type of antioxidant — that appears in extra-virgin olive oil. It’s no accident the stuff appears in so many of the world’s healthiest diets. In addition to the heart-healthy antioxidants, olive oil provides a rich source of healthy fats that may preserve brain health and improve memory.

“We think oleocanthal could explain reduced [cancer] incidence in Mediterranean diets where consumption is high,” Foster told Medical Daily in an email. “And it is also possible that purified (higher-dose) could possibly be used therapeutically.”

Ultimately, the co-authors want to learn more about why oleocanthal targets and shrinks cancer cells specifically. “We also need to understand why it is that cancerous cells are more sensitive to oleocanthal than non-cancerous cells,” Foster said in the release. Even if consuming more olive oil won’t necessarily protect you from cancer today, budding research may help bring [some of its compounds] into the hospital in the future.
