The secret to the Mediterranean diet may be in the salad. Eating unsaturated fats, like those in olive oil, along with leafy greens and other vegetables creates a certain kind of fatty acid that lowers blood pressure, scientists said Monday. These nitro fatty acids are formed when consuming spinach, celery and carrots that are filled with nitrates and nitrites, along with avocado, nuts and olive oils that contain healthy fats. Nitro fatty acids appear to inhibit an enzyme known as soluble epoxide hydrolase, which regulates blood pressure, said the research in the Proceedings of the National Academy of Sciences, a...

Omega-6-rich oils don't have same benefits as canola, soybean and olive oils, studies show The Canadian Press Posted: Nov 11, 2013 1:46 PM ET Last Updated: Nov 11, 2013 2:10 PM ET In 2012, Health Canada agreed to let manufacturers of cooking oils containing either omega-6 or omega-3 fatty acids claim on their product labels that these oils help reduce the risk of heart disease by lowering cholesterol. (iStock) A pair of Canadian scientists are challenging the fact that manufacturers of some cooking oils are entitled to make health claims about the products. They argue that new evidence suggests oils...

Source: American Society for Biochemistry and Molecular Biology Date: May 7, 2007 Fish, Seafood Better Than Olive Oil, Nuts Against Heart Disease Science Daily — Researchers have found that a diet rich in fish, seafood, and grains -- also called polyunsaturated fats -- is better at preventing heart disease than a diet containing olive oil, nuts, and avocados -- called monounsaturated fats. Although both types of fats are healthy, people should probably include more of the first than the second in their diet to keep a healthy heart, the scientists say. Too much cholesterol has long been linked to increasing...

Health conscious consumers have long known that virgin olive oil is a good choice when it comes to preparing meals and dipping breads. Now, a team of researchers, including one with the Agricultural Research Service (ARS), has found that phenolic components in olive oil actually modify genes that are involved in the inflammatory response. The researchers knew from other studies that consuming high-phenolic-content virgin olive oil reduces pro-inflammatory, pro-oxidant and pro-blood-clotting biomarkers when compared with consuming low-phenolic-content olive oil. But they wanted to know whether olive oil’s beneficial effects could be the result of gene activity. The study, published recently...

When it comes to heart health, virgin olive oil may have an edge over other vegetable fats, new research suggests. Reporting in the Annals of Internal Medicine, European researchers say virgin olive oil may be particularly effective at lowering heart disease risk because of its high level of antioxidant plant compounds. In a study of 200 healthy men, the researchers found that virgin olive oil -- rich in antioxidants called polyphenols -- showed stronger heart-health effects than the more extensively processed "non-virgin" variety. The findings suggest that virgin olive oil has more going for it than its supply of heart-healthy...

[Health India]: Washington, Jan 10 : A team of researchers from the Northwestern University Feinberg School of Medicine in Chicago, have revealed why Mediterranean diets, which include a lot of olive oil, reduces breast cancer risk in women. The study, which has been published in the "Annals of Oncology" also found evidence that oleic acid, which is found in olive oil, may have a future role in treatment. The researchers said that oleic acid dramatically cuts the levels of an oncogene called Her-2/neu, also known as erb B-2. High levels of Her-2/neu occur in over a fifth of breast cancer...

Olive oil is in the news, and the news is good. Last week's findings by Northwestern University in Chicago that olive oil can help fight breast cancer, is just the latest of many health benefits that have been shown to be derived from this oldest of medicinal foods. "Our findings underpin epidemiological studies that show that the Mediterranean diet has significant protective effects against cancer, heart disease and ageing," said the study's lead author, Javier Menendez, of Northwestern University's Feinberg medical school. One of the few non-drug products that has gained FDA approval, olive oil was attributed by the agency...

A study of more than 22,000 Greeks provided further evidence on Wednesday that the "Mediterranean diet" rich in cheese, nuts and olive oil can protect against heart disease and cancer. The study found that people who ate a Mediterranean-style diet had a 33 percent reduction in the risk of death from heart disease and a cancer death rate that was 24 percent lower compared to volunteers who ate other foods. The diet, which varies from country to country, often includes monthly servings of meat and weekly meals of poultry, eggs and sweets. Vegetables, fruits, nuts, legumes, unrefined cereals, olive oil,...

The earliest evidence of the use of olive oil in the country, and possibly the entire Middle East, was unearthed at an excavation site in the Lower Galilee, the Antiquities Authority announced Wednesday. The discovery was made after Dr. Ianir Milevski and Nimrod Getzov directed an archeological salvage excavation at Ein Tzipori between 2011 and 2013. The excavation led to research that indicated that olive oil was already being used in the country 8,000 years ago, during the 6th millennium BCE... These tests revealed that the pottery, dating to the Early Chalcolithic period, contained olive oil, the researchers concluded... Of...

But some places are on the right track.  National Geographic writer Dan Buettner seeks out "Blue Zones," a few pockets around the world where a higher number of people live for a remarkably long time. The remote island of Ikaria in Greece is one hotspot of exceptional human longevity. Here, there are more healthy people over 90 than any other place on the planet. Buettner and his team spent 15 months studying the centenarians of Ikaria. The trip was documented in a series of videos, in which...

Scientists at the University of Granada have shown that oleic acid and hydroxytyrosol –present in a particularly high concentration in virgin olive oil– and n-3 polyunsaturated fatty acids –found in fish– relieve the symptoms of pancreatitis. The researchers evaluated the role of Mediterranean diet ingredients in the prevention and mitigation of cell damage. Oleic acid and hydroxytyrosol –present in a particularly high concentration in virgin olive oil– and n-3 polyunsaturated fatty acids –found in fish– affect the cellular mechanisms involved in the development of acute pancreatitis, a disease of oxidative-inflammatory etiology. Therefore, oleic acid and hydroxytyrosol can be considered...

Shipwreck Yields World's Oldest Salad Dressing Jennifer Viegas, Discovery News June 20, 2008 -- Olive oil infused with fragrant herbs has been identified in an ancient Greek ceramic transport jar known as an amphora, along with another container of what could be the world's oldest retsina-type wine, according to a recent Journal of Archaeological Science paper. It is the first time DNA has been extracted from shipwrecked artifacts -- the two large jars were recovered from a 2,400-year-old wrecked vessel off the Greek island of Chios. If the second jar indeed contained a retsina-like wine, which is preserved and flavored...

The Secret To Long Life May Not Be In The Genes ScienceDaily (May 6, 2008) — A research on the bone health of one of the oldest persons in the world, who recently died at the age of 114, reveals that there were no genetic modifications which could have contributed to this longevity. The research team, directed by Universitat Autònoma de Barcelona professor Adolfo Díez Pérez, pointed out a healthy lifestyle, a Mediterranean diet, a temperate climate and regular physical activity as the reasons for his excellent health. The research team studied the bone mass and analysed the genetics of...

The Mediterranean diet, which includes olive oil, vegetables and pasta, has long been considered beneficial to health, particularly heart health. However scientists now claim to have discovered why this diet also appears to protect women from breast cancer. According to the researchers, the answer lies in olive oil, or more specifically, one of the ingredients of olive oil - oleic acid. They found that this fatty acid significantly reduced the levels of a gene - Her-2/neu - which is thought to trigger breast cancer. This gene is found in high levels in around one in five breast cancer patients and...

LONDON (Reuters) - Scientists have discovered why eating a Mediterranean diet rich in fruits, vegetables and particularly olive oil can help to protect women from developing breast cancer. The key is oleic acid, the main component of olive oil. Dr Javier Menendez, of Northwestern University Feinberg School of Medicine in Chicago, said oleic acid blocks the action of a cancer-causing oncogene called HER-2/neu which is found in about 30 percent of breast cancer patients. "We have something now that is able to explain why the Mediterranean diet is so healthy," Menendez told Reuters. Doctors and researchers had been aware that...
