New research indicates that people who ingest more olive oil, grapeseed oil and peanut oil are less likely to get ulcerative colitis.

A new study by researchers at the University of East Anglia has shown that consuming more olive oil can actually prevent ulcerative colitis.  The findings were presented at this year’s Digestive Disease Week conference in New Orleans.  The study centered on oleic acid, which is present in olive oil, peanut oil and grapeseed oil.  Oleic acid is a monounsaturated fatty acid.

Over 120,000 people in the UK and 1 million in the US have ulcerative colitis.  The disease causes inflammation in the lining of the colon and bowel leading to pain and diarrhea.  Other symptoms of ulcerative colitis include fever, weight loss, and gastrointestinal bleeding.

This new research studied over 25,000 middle-aged people in the UK who did not have ulcerative colitis.  The participants completed food diaries during the study, which were then analyzed by nutritionists.

When researchers analyzed the results, they found that the people, who developed ulcerative colitis, had the lowest intake of oleic acid.  On the other hand, those who ate the most foods with oleic acid had a 90% less change of getting ulcerative colitis.

Dr. Andrew Hart was the leader of the research, he stated, “We estimate that around half of the cases of ulcerative colitis could be prevented if larger amounts of oleic acid were consumed.  Two-to-three tablespoons of olive oil per day would have a protective effect.”

Other dietary suggestions for those with ulcerative colitis include drinking lots of water, eating smaller portions, and avoiding fattening greasy foods.  Obviously, these are good suggestions for everyone, even if this digestive issue does not impact them.

Fibromyalgia remains a health problem that is surrounded by a great deal of mystery. However, researchers have proved that those people who exercise and are at a healthy weight are less likely to develop the problem.

A new study from Norwegian University of Science and Technology has shown that overweight and obese women are more likely to develop fibromyalgia.  This study was published in the May issue of Arthritis Care and Research.

Fibromyalgia includes long-lasting pain in points including the neck, shoulder, back, hips, arms and legs.  People with this issue commonly have fatigue, headaches, and trouble with their moods.  Sleep can also be disrupted. The cause of this problem is unknown, though genetics are believed to be a factor.

Some experts believe that fibromyalgia is caused from a dysfunctional nervous system.  Fibromyalgia impacts over 2% of the population of the United States.  Women are more likely than men to develop this problem. The likelihood of fibromyalgia also increases with age.

In this Norwegian study, 16.000 people were surveyed over a period of years.  As it turned out, of the group 380 people developed fibromyalgia. The patient’s exercise habits and BMI were examined over the years.  The results showed that people who exercised and were at a healthy weight were far less likely to have fibromyalgia.

Lead researcher Paul Mork said, “Women who reported exercising four times per week [or more] had a 29 percent lower risk of fibromyalgia compared with inactive women.”  Additionally, women who were heavier had a 60-70% higher change of getting fibromyalgia.  However, the overweight women who exercised were less likely to develop the problem.

As fibromyalgia does seem to run in families, this news is especially relevant for those with a family history.  Those who already have the condition can reduce pain if they reduce their weight and incorporate exercise into their routine.

Vitamin E has been shown to improve liver function for those with fatty liver disease. This is a serious issue that impacts approximately 5% of Americans and can actually be fatal in some cases.

One of the most common liver diseases related to obesity is called fatty liver disease.  Unfortunately, doctors currently believe that this issue has no form of treatment.  However, researchers from the Virginia Commonwealth University have discovered that Vitamin E can help patients with fatty liver disease.  Researchers were surprised at these findings, as typically vitamin supplements are only thought by medical professionals to treat problems caused by nutritional deficiencies.

When people have fatty liver disease, fat can build up in the liver and cause inflammation as well as scarring.  Eventually this can cause a liver to fail in some extreme cases.  Fatty liver disease is common in middle-aged people who are overweight.  Up to 5% of Americans are reported to have this issue.

In this new study, 247 people with advanced fatty liver disease were assigned to one of three groups.  One group took vitamin E in a high dosage, one group took a placebo and one took a diabetes drug called Actos. Biopsies showed that those who took Vitamin E saw a 43% increase in liver function.  While participants who took Actos also saw improvement in their livers, the percentage of increased liver function was not as high as in the group taking Vitamin E.  Also these people who took Actos gained weight during the experiment.

Other treatments for fatty liver disease include losing weight by eating right and exercising.

Aside from treating fatty liver disease, Vitamin E also has a number of other health applications.  As an antioxidant, it can fight cell damage that is caused by free radicals.  It can also protect against prostate cancer and Alzheimer’s disease.  As Vitamin E taken in large doses can be toxic, be sure to follow the recommendation on the label.  Also, consult with your physician prior to supplementing with Vitamin E if you’re taking a blood thinner.

Last but not least, synthetic vitamin E doesn’t work the same as natural Vitamin E.  Therefore, be sure to take the natural form, which is D-alpha tocopherol.

Researchers have discovered that increased omega-3 fatty acids can reduce the risk of colon cancer. This can come from food sources or fish oil supplementation.

Do you get tons of omega-3 fatty acids in your diet?  If so, new research indicates you will reduce your risk of colon cancer.  Taking fish oil supplements can also accomplish the same goal.

According to Dr. Sangmi Kim at the National Institute of Environmental Health Studies in Research Triangle Park, North Carolina, not only can fish oil supplementation fight inflammation, it can also reduce the risk of cancer.

The study examined polyunsaturated fatty acid intake and bowel cancer risk in both whites and African Americans.  Approximately, half of the people in each group were colon cancer patients.  The other half served as the control group.

The researchers found that the people in the group of whites, who consumed the top forth amount of omega-3s, had half the risk of colon cancer.  They also found that fish oil had the same effect.  Although when the black participants were analyzed separately, they didn’t see cancer rates drop as omega 3 intake increased.  However, researchers stated, “Whether the possible benefit from this dietary modification varies by race warrants further evaluation.”

So where can you get the necessary omega-3 fatty acids? They are found in walnut oils, flaxseed oil, and leafy greets.  It is important to remember to eat more omega-3s than omega-6 fatty acids, as you want a healthy balance in your diet.  It can be unhealthy to have more omega-6 in your system. Omega-6 acids can be typically be found in oils like soybean oil and sunflower oil as well as meats.  While omega-3 oils reduce inflammation, omega-6 oils can cause inflammation.

Frequent readers of Natural Health on the Web know that I am a big advocate of the Mediterranean diet. This diet suggests eating foods high in omega-3 fatty acids like fruits, vegetables, olive oil and fish rather than omega-6 rich meats.

Announcements at this year’s American Association for Cancer Research Event included the findings that there is a connection between vitamin supplementation and breast cancer rates.

If you have been taking vitamins and calcium supplements, there is good news concerning your risk of getting breast cancer!  New findings about breast cancer prevention were announced at this year’s American Association for Cancer Research 101^st Annual Meeting. The event took place April 17-21^st in Washington DC.  The meeting attracts over 15,000 attendees each year.

This year one of the presentations included conclusive information that vitamins and calcium supplements have been shown to be effective in reducing the risk of breast cancer.  This new research involved 457-control group and 268 women with breast cancer.  The study showed that vitamins reduced breast cancer risk by about 30%.  Calcium supplements, on the other hand, actually reduced the risk by 40%.

One of the people presenting this information was Jaime Matta PhD from the Ponce School of Medicine in Puerto Rico.  Matta stated, “This process involves at least five separate pathways and is critical for maintaining genomic stability.  When the DNA is not repaired, it leads to mutation that leads to cancer.”  Apparently, calcium supplements enhance DNA repair.  If this complex repair process is interrupted it can lead to cancer.

In addition to supplements reducing the risk of breast cancer, there are also different superfoods that are effective at fighting breast cancer as well. These superfoods include fatty fish, beans, berries and tomatoes.

A compound in dark chocolate has been shown to protect cells after a stroke.

A study at Johns Hopkins has shown that dark chocolate contains a special compound, which can protect the brain after a stroke.  As it turns out, the dark chocolate increases cells that are designed to protect nerve cells from damage. The Journal of Cerebral Blood Flow and Metabolism recently published this study.

Researchers induced a stroke in mice 90 minutes after giving mice a compound in dark chocolate called epicatechin.  Epicatechin is a member of the compounds named plant flavonoids. Flavonoids also work to prevent blood clots and damage caused by clogged arteries.

To induce the stroke, researchers cut blood to the mice’s brains.  They found that the animals that had received the dark chocolate compounds were less likely to receive brain damage.  Also researchers learned that they could give the epicatechin to the animals 3.5 hours after the stroke.  Usually treatments for humans who have had strokes need to be given 2-3 hours later to be effective.  Therefore, this means that doctors can wait longer before administrating epicatechin treatments to patients.

The lead research on this study is Sylvain Dore, PhD.  He said that his study showed that epicatechin stimulated pathways that can shield the brain from damage.  Dore hopes that his studies on dark chocolate and epicatechins can help begin to limit the kinds of damage caused by stress.

If you are turning to chocolate for health benefits, always remember to reach for the dark chocolate.  But don’t forget that the higher the cacao content, the better.

Just Five Minutes of Exercise Outdoors Boosts Mental Health, Researchers Say

In a bad mood? Improve it by going outside!

Here in New York and all around the country, summer is in the air.  It may say “May” on the calendar, but the weather sure doesn’t know that, as this week’s temperatures in New York City are headed for the 70s and 80s!

I hope it’s as nice where you are as it is here.  And if it is, instead of going to the gym after work to exercise today, head outside…even if it’s for just five minutes.  Because according to a new study on the mental health effects of exercising outside, the great outdoors can heighten your mood and your self-esteem.

Researchers from the University of Essex discovered this after reviewing the health habits of over 1,200 people from 12 separate studies.  Among the information collected from these men and women of all ages was their state of mental health (i.e. were they diagnosed with any kind of mental health disorder and cognitive dysfunction) and the kind of activities they did outside, such as walking, bicycling, gardening or horseback riding.

All of the individuals who exercised regularly showed improvements in their mental health, but those who saw the most significant improvement were those who performed what the researchers call “green exercises.”  Green exercises are any of the aforementioned exercises performed outside.  Other green exercises include farming, walking, gardening, fishing or boating.

“We believe that there would be a large potential benefit to individuals, society, and to the costs of the health service if all groups of people were to self-medicate more with green exercise,” said Jo Barton in a statement.  Barton co-authored the study with her colleague, Jules Pretty.

Their complete findings can be found in the journal Environmental Science & Technology.

Oh, and if you’re someone who loves the ocean, then you’re going to love this:  the biggest mental health effects were found among those who live near the water, like the ocean, a river or lake.

So, it seems, the closer you are to blue, the less likely you are to get “blue.”

As with many studies, this probably confirms the obvious.  But this research is illuminating nonetheless because up to now, no one really knew just how long it took to be outside to reap the mental health benefits.  And according to the researchers, it takes as little as five minutes.

So you know what that means?  No more excuses.  No more saying, “I can’t go outside for a walk because I don’t have any time on my lunch break.” Everybody has at least five minutes they can spend outdoors to walk.

Now, ideally, you’ll be exercising for longer than five minutes, but as I always say, some exercise is better than no exercise.  And that’s every bit as true for the mind as it is for the body.

Researchers Say Diet Influences Alzheimer’s Risk

Columbia researchers say you can cut your risk for Alzheimer's disease through proper nutrition.

One fact that I’ve hammered over my readers’ heads over the years is the prevalence of heart disease.  It remains the number one cause of death for Americans, but believe it or not, between the years 2000 and 2006, there’s been an 11 percent drop in heart disease related deaths.  Other conditions where there’s been a decline in deaths include stroke (18 percent fewer), prostate cancer (8 percent fewer) and HIV (16 percent fewer).

That’s good news, but as is typical when good news is reported, here comes the bad news: There’s been a dramatic rise in Alzheimer’s related deaths.  In fact, comparing 2006 to 2000, there’s been a near 50 percent rise in Alzheimer’s related deaths, making it the seventh leading cause of death in the U.S.  Approximately 26 million people have Alzheimer’s in the world, 5.3 million of whom live stateside.

While advances are being made every day in doctors’ knowledge about this mysterious brain disease, there’s no cure for it.  Medicines are available to slow its progression, but nothing can stop its advancement.  In short, once you have it, you can’t get rid of it.

Thus, prevention remains your best defense.  And it’s becoming clearer and clearer that it all starts with your diet.  Researchers from Columbia University confirm this.

Researchers discovered this recently after analyzing the dieting habits of approximately 2,150 adults over the age of 65 for four years.  Through food frequency questionnaires and annual checkups (i.e., every 18 months), they wanted to see if there was any correlation between what people were eating and whether or not they were eventually diagnosed with Alzheimer’s.

According to their results, people who tended to eat a diet similar to the Mediterranean diet – one that’s rich in vegetable oils like olive oil, fresh fruits and vegetables like berries and broccoli, as well as nuts like almonds and walnuts—were 40 percent less likely to have developed Alzheimer’s disease.  Other brain boosting foods include seafood sources high in omega-3s like snapper and salmon.

The people more likely to have developed Alzheimer’s were those who ate diets high in saturated fat from food sources like butter, organ meat and red meat.

The full findings appear in the pages of the Archives of Neurology.

Yet more evidence that our diet plays a HUGE role in how healthy our mind will be.  No, a healthy diet doesn’t guarantee you’ll be from Alzheimer’s disease, but if you’ve had relatives with Alzheimer’s, you’d be foolish not to take every precaution available.  Not much is known about Alzheimer’s but what is known is that’s its hereditary.

Another Reason to Opt for Wheat Over White

Italian researchers find that women who eat white bread have two times the risk of heart disease than women who eat wheat.

When we were young and our folks asked us what bread we wanted our peanut butter and jelly on—white or wheat—our answer depended upon our mood at the time.  Did we want the white, which had a more bland taste but soaked up the jelly and peanut buttery goodness, or did we want the wheat, which had a more distinctive taste but didn’t marry with the PB and J quite as well as the white did?

Now that we’re older—and with any luck more health conscious than taste conscious—we hopefully choose wheat over white because it has the complex carbohydrates and fiber that white bread is void of, both of which are great for maintaining healthy weight levels and regularity.

But there’s another why white should always play second fiddle to wheat:  It may double your risk for heart disease.

In a new study published in the Archives of Internal Medicine, Italian scientists found that women who tended to eat high glycemic foods like white bread, pastries and ice cream had more than two times the risk of having heart disease later in life compared to women who ate foods low on the glycemic index.

Writing in the journal, Italian scientist Sabina Sieri and her colleagues said, “A high consumption of carbohydrates from high glycemic index foods, rather than the overall quantity of carbohydrates consumed, appears to influence the risk of developing coronary heart disease.”

The study of 32,500+ women also looked into the diets of over 15,100 men to see if their consumption of high glycemic foods affected their heart health.  But interestingly, no such linkage could be made between the kinds of carbohydrates men ate.  Researchers attribute the differentiation to the fact that men and women metabolize foods differently.

So, does this give men the green light to eat white bread and corn flakes whenever they want?  Alternatively, does this mean women should avoid white bread like the plague?

To both, the answer is no.  There’s nothing wrong with an occasional sandwich with white bread, so long as your bread options are more often than not 100 percent whole wheat.

And men, while your choice of bread may not influence your heart disease risk, a 10-year study conducted by Harvard researchers in 1994 found that men who ate high fiber breads like wheat had fewer heart attacks and fewer strokes than men who opted for white.

So when you’re out perusing the bread aisle and deciding what bread’s best, keep the white out of sight and make wheat your new favorite treat.

But buyer beware:  Don’t assume that brown in color means it’s wheat.  Many breads are made with refined flour; they’re just dyed brown with caramel color to make it look like they’re wheat. Read the ingredients label.  If the first listing doesn’t say “100 percent whole wheat,” put the brown down.

Green Tea Expands its Health Promoting Repertoire

German researchers find improved fat oxidation when men combine EGCG with caffeine.

From improving arthritis symptoms to preventing heart disease, heightening eye health to discouraging Alzheimer’s disease development, green tea is the libation of choice for health aficionados.  Yet as multifaceted a drink green tea is, could encouraging weight loss be added to its repertoire?  German researchers sure think so.

A team of researchers from Berlin’s University Medicine recruited 10 middle-aged men who, besides being obese, were generally healthy.  They broke the 10 men into groups of two and randomly assigned them to take an allotted amount of EGCG, some in high doses, others in low doses.  EGCG is the antioxidant compound in green tea believed to make it such a nutritional powerhouse.

One of the cooler aspects of this study is that all the men got a turn in taking a specific amount of EGCG.  In other words, instead of taking a specific amount of EGCG for the length of the study period, the men would take 300 mg of EGCG for three days, then go off for seven days, then pick up their EGCG regimen for another three days.  But instead of taking the same amount as last time, they’d take 600 milligrams.  Then go on to another group 10 days later.  So by the end of the study, all 10 men had gone through the five regimens.

(To be honest, I wish more studies were set up like this.  It makes the results of the study more reliable.)

By the end of the study, the researchers found increases in fat oxidation across the spectrum.  Compared to the time in which they took a placebo for three days, fat oxidation increased 33 percent (300 mg of EGCG daily), 20 percent (600 mg of EGCG daily), 34.5 percent (200 mg of caffeine), and 49 percent (200 mg of caffeine combined with 300 mg of EGCG).

What’s interesting is that there was greater fat oxidation when the men took the lower EGCG combination as compared to the high EGCG combination.  So apparently the Goldilocks rule applies to EGCG—not too much, not too little, but an amount that’s “just right” works for weight loss.

The question, of course, is how many drinks of green tea must one guzzle in order to see any significant weight loss?

Researchers say it may be as few as three drinks or as many as 10 drinks…per day!  Now, as much as I like to drink tea, I don’t have the time, nor the inclination to drink that amount of green tea every day!

But that as it may, the very fact that I could lose weight by drinking that amount of green tea every day illustrates just how amazing a drink green tea is.

The study is published in the European Journal of Clinical Nutrition.
