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 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...

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...

Jeremy Vandel/Flickr There's no magic bullet to living beyond the age of 100. 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...

Modern men's genes suggest that something peculiar happened 5,000 to 7,000 years ago: Most of the male population across Asia, Europe and Africa seems to have died off, leaving behind just one man for every 17 women. This so-called population "bottleneck" was first proposed in 2015, and since then, researchers have been trying to figure out what could've caused it. One hypothesis held that the drop-off in the male population occurred due to ecological or climatic factors that mainly affected male offspring, while another idea suggested that the die-off happened because some males had more power in society, and thus...

For the study, the researchers performed stable isotope analyses on 712 animal bones collected from at least 90 archaeological sites in Ireland. The researchers found significant changes in the nitrogen composition of soil nutrients and plants that made up the animals' diet during the Bronze Age. The researchers believe the changes were the result of an increase in the scale and intensity of deforestation, agriculture and pastoral farming. While these results are specific to Ireland during the Bronze Age, Guiry said the findings have global implications. "The effect of human activities on soil nitrogen composition may be traceable wherever humans...

For the Polynesian islands, that meant the arrival of agricultural crops like breadfruit, yams and taro, as well as domesticated animals like dogs, pigs and chicken. The early settlers also used slash-and-burn agriculture to remove forests and fertilize the soil and likely hunted many seabirds to extinction. To get a more precise view of how human behavior impacted the islands, Swift and her colleagues used stable isotope analysis. Carbon analysis is based on the way plants process carbon dioxide: most agricultural products are classified as C3 plants, while tropical grasses are usually C4 plants. If rat bones show a higher...

A British company says it can greatly extend the range of crops grown in indoor growing formats beyond the established leafy greens and herbs. Discussions on the potential of urban and indoor farming invariably mention the need to feed a growing global population, forecast to reach 10 billion by the middle of the century, against a backdrop of climate change and depleted land and other resources. But so far, for technical and economic reasons, the movement has largely targeted leafy greens and herbs — relatively high-value but low-mass, low-calorie crops. Indeed, one successful London grower specialises in "micro-salads" sought by...

Archaeologists have unearthed the final resting place of an ancient racehorse among the ruins of the ancient city of Pompeii in Italy. The horse was discovered in Pompeii’s northern outskirts, beyond the walls of the Roman city. The stable where the horse belonged to a villa in Pompeii’s suburb of Civita Giuliana. Experts discovered the horse’s remains when they were investigating tunnels used by tomb raiders, according to a Facebook post.

For the first time ever, archaeologists have been able to cast the complete figure of a horse that perished in the volcanic eruption at Pompeii. The "extraordinary" discovery was made outside the city walls, in Civita Giuliana to the north of Pompeii proper, the site's directors announced this week. Excavation in the area revealed what archaeologists identified as a stable, complete with the remains of a trough. Using the same technique that has allowed them to recreate the final poses of dozens of Pompeii's victims, whereby liquid plaster is injected into the cavities left behind when bodies encased in volcanic...

Sweet potatoes were domesticated thousands of years ago in the Americas. So 18th century European explorers were surprised to find Polynesians had been growing the crop for centuries. New genetic evidence instead suggests that wild precursors to sweet potatoes reached Polynesia at least 100,000 years ago — long before humans inhabited the South Pacific islands, researchers report April 12 in Current Biology. If true, it could also challenge the idea that Polynesian seafarers reached the Americas around the 12th century. For the new study, the researchers analyzed the DNA of 199 specimens taken from sweet potatoes (Ipomoea batatas) and...

A trio of dogs buried at two ancient human sites in Illinois lived around 10,000 years ago, making them the oldest known domesticated canines in the Americas. Radiocarbon dating of the dogs’ bones shows they were 1,500 years older than thought, zooarchaeologist Angela Perri said April 13 at the annual meeting of the Society for American Archaeology. The previous age estimate was based on a radiocarbon analysis of burned wood found in one of the animals’ graves. Until now, nearly 9,300-year-old remains of dogs eaten by humans at a Texas site were the oldest physical evidence of American canines.

A Japanese variety of sweet potato Pixabay _______________________________________________________________________________________________________________ At some point, sweet potatoes crossed the Pacific. This much we know. As for the rest—How? When? Why?—we’re just not sure. Or, to be more clear, some people are sure they’re sure, and others disagree. Sweet potatoes have been at the center of a massive archaeological debate for many decades now, and a new paper in Current Biology has only stoked the flames. It uses genetic data from sweet potatoes and their relatives to establish a phylogenetic tree of their evolution, thereby demonstrating that the tubers existed in Polynesia before humans lived...
