Mediterranean diet helps protect bones‎,says recent study

By DR. SWATI SHROFF, ABC News Medical Unit

Could olive oil be the new milk? A new study suggests that this might be the case — though not all health experts are convinced yet.

The study, which looked at 127 elderly Spanish men, found that those who ate a Mediterranean diet enriched with olive oil had higher levels of a protein called osteocalcin that plays a role in bone formation. The research was published in the Journal of Clinical Endocrinology and Metabolism.

This could be an important finding since osteoporosis is the most common bone disease in the United States, affecting more than 10 million people. Osteoporosis mainly affects elderly women, but men can develop the disease too. In 2005, there were an estimated 2 million osteoporosis-related fractures, 29 percent them in men.

Earlier studies have found that there are lower rates of osteoporosis in the Mediterranean basin, compared to the rest of Europe, and that may have something to do with the Mediterranean diet. This diet consists of minimally processed fruits, vegetables, breads, beans, nuts and seeds. Olive oil is supposed to be the main source of fat, and there is usually limited dairy, egg, and red meat.

Past studies have suggested that the Mediterranean diet has the potential to lower cardiovascular risk, increase weight loss, lower cancer risk, improve diabetes, and reduce pain and swollen joints in rheumatoid arthritis. What if improved bone health could be added to this growing list?

“We have more evidence that what is good for health in one way, tends to be good for health overall,” says Dr. David Katz, director of Yale University Prevention Research Center. “The very same Mediterranean diet known to be good for cardiovascular health may also confer benefits on your bones.”

However, Dr. Beth Kitchin, a patient educator at the University of Alabama at Birmingham Osteoporosis Clinic, cautions that osteocalcin is simply a marker of bone health — in other words, the new study doesn’t actually look at whether the Mediterranean diet increased bone density or lowered fracture risk.

“This is very interesting data but much, much more work needs to be done before you can say if this has a true clinical impact on bone health,” says Kitchin.

On this point, Katz agrees. “This is not a study of bone density, or clinical effects; it is a short-term study of biomarkers. Interesting, but [it is] more useful for hypothesis generation than anything else.”

Nutritionists were also quick to point out that this study shouldn’t undermine the importance of calcium and vitamin D in bone health.

“It doesn’t replace calcium and vitamin D in the diet, however,” says Keith-Thomas Ayoob, a dietician and professor at Albert Einstein College of Medicine. “But including all three, and regular exercise, are showing promise as the best way to ensure good bone health.

“I was brought up on a high-olive oil [Mediterranean] diet. It’s how we ate. But not much milk or calcium-containing foods, and my elders paid a price for it.”

Mediterranean diet 'aids fertility'

Men who eat a diet rich in fruit, vegetables and fish could boost their chances of becoming a father, according to a new study.

A Mediterranean-style diet, which also contains leafy vegetables, pulses and whole grains, can enhance sperm motility by 11%.

This could be especially important for couples who are trying to conceive naturally due the need for sperm to be "strong swimmers".

The research comes as a separate study found that men who take moderate exercise can also positively impact their sperm motility. Both studies were presented at the American Society for Reproductive Medicine (ASRM) conference in Orlando.

In the first, experts from universities including the Harvard School of Public Health, examined the diets of more than 180 men aged 18 to 22. They split those who ate any Mediterranean-type items into four sub-sets, from those with the highest intake of these nutrient-rich foods to those with the lowest. Those in the highest group had an increased sperm motility of 11% compared to the lowest.

Audrey Gaskins, from Harvard's Department of Nutrition, said: "I think motility is most important for couples who are trying to conceive naturally. It's our hope that a small increase could lead to a small increase in fertility rates."

Dr Allan Pacey, senior lecturer from the academic unit of reproductive and developmental medicine at the University of Sheffield, said the influence of a man's diet on semen quality had been of interest for some time. He said the latest study "nicely illustrates that a good diet is of benefit when trying to conceive".

In the second study, from experts at Yamaguchi University in Japan, 215 men attending an IVF clinic completed a questionnaire about their exercise habits and gave semen samples.

The group reporting moderate exercise had the highest average sperm motility as well as a significantly lower percentage of men with less than 40% sperm motility (14.3%). In the lowest exercise group, 30.8% of men had sperm motility under 40% and 27.1% of men who exercised intensely had sperm motility under 40%.

Dr Dolores Lamb, president-elect of the ASRM, said: "Exercise is a component of an overall healthy lifestyle, which contributes to reproductive health. This study which uses frequency, intensity, and duration to quantify the amount of exercise a subject gets, shows that a moderate exercise routine may be recommended to modestly improve semen parameters in men with no known conditions that impair their reproductive capacity."

Mediterranean Diet can help People live longer

Here is a little secret on how one can live a longer and healthy life,The Mediterranean Diet can increase a woman's lifespan by as much as 15 years and increase a man's life by 8 years,according to a new study.
Researchers at Maastricht University tracked 120,000 men and women between the ages of 55 and 69. Each person was given a score in 1986 based upon his/her adherence to four key factors that have been shown to affect mortality: smoking, physical activity, body weight, and dietary habits.

What happened? Men who avoided smoking, exercised at least 30 minutes a day, avoided obesity, and stuck to the heart-healthy Mediterranean Diet lived about 8.5 years longer, on average, than men who didn't do any of those things, according to a written statement released by the university. 

Healthy living had an even bigger effect on women's lifespans. On average, those who met all four criteria lived 15 years longer than women who met none.

Fifteen years? Eight-and-a-half years? Those are huge numbers, especially given that life expectancy in the U.S. - where healthy living isn't exactly the norm - now stands at 77.9 years.

“I was surprised that the effect was so big. I was also surprised at the big difference between men and women”, said lead researcher Piet van den Brandt. He also went on to say  he wasn't sure why healthy living women would live so much longer than their male counterparts. One possibility, he said, was that hormonal differences explained the difference. 
so there you go people,start following The Mediterranean Diet if you want a long healthy lifestyle with your family. 

The Mediterranean Diet Nutrients Benefits The Heart

ST. CHARLES, Mo.–Olive extract, lycopene, chitin-glucan and green tea are promising nutrients present in the Mediterranean Diet that have been shown in clinical trials to reduce oxidized low-density lipoprotein (OxLDL), a pro-atherogenic mediator and biomarker for cardiovascular disease (CVD), according to a recent article written by Joseph L. Evans, Ph.D., manager, pharmacology for Stratum Nutrition and Novus Research fellow (Agro Food Industry.2011 March/April;40-2). Supplements that contain these natural ingredients may therefore help reduce the growing incidence of CVD.

"There are several historically-used measurements for identifying individuals at risk for developing cardiovascular disease, including levels of LDL- and high-density lipoprotein (HDL) cholesterol, total cholesterol and high blood pressure to name a few," Evans noted. "However, there are other biomarkers, including OxLDL and the OxLDL / HDL cholesterol ratio that have been shown in clinical research to be more sensitive indicators for discriminating between individuals with and without coronary artery disease (CAD) when compared to the commonly measured biomarkers. And consuming a Mediterranean diet is an effective way to reduce levels of OxLDL and improve overall cardiovascular health."

The Mediterranean Diet is rich in foods with strong antioxidant properties, such as fruits, vegetables, olive oil and nuts. Research has indicated that the nutrients contained in these foods increase the expression of those genes involved in our body's antioxidant defense system, and suppress those genes involved in advancing inflammation and atherogenesis. While the precise mechanism(s) responsible for nutrient-mediated reduction in OxLDL is unknown, it likely involves the increased expression of circulating and intracellular antioxidant enzymes, along with the inhibition of enzymes that contribute to increased production of reactive oxygen species.
