Wednesday, Sep 2nd, 2009 ↓Melons can fight blood pressure →
Sept 2, 2009 (Presstv.com)—Following a diet rich in potassium-rich fruits and vegetables such as melons, commonly found in summer, can help lower the blood pressure.
Potassium chloride had long been used to lower blood pressure levels. A new study, however, finds any increase in potassium intake can also lead to similar results.
According to the study recently conducted at UT Southwestern Medical Center, the high potassium content of certain fruits including fresh melons can help athletes and those suffering from high blood pressure.
Scientists concluded that increasing potassium intake has the same effect as taking potassium chloride.
The US Department of Agriculture officials hence urged adults to get some 4,044 milligrams of potassium from food and beverages each day.
“Melons like cantaloupe and watermelon are particularly high in potassium,” said lead researcher Lona Sandon, adding that one fourth of a cantaloupe contains 800 to 900 milligrams of potassium, roughly 20 percent of the recommended daily value.
Two cups of watermelon contains nearly 10 percent of the recommended daily value.
Dried apricots, avocados, figs, kiwi, oranges, raisins, dates, beans, potatoes, tomatoes and even grapefruit are other good sources of potassium.

Blueberry juice displays weight management benefits: Mouse study →
Sept 2, 2009 (Foodnavigator.com)—Drinking a modified blueberry juice may reduce food intake and body weight, and offer weight management potential, suggest findings from a new study with mice.
Canadian researchers report that mice prone to obesity, insulin resistance, diabetes and hypertension drinking the blueberry juice were protected against the development of glucose intolerance and diabetes mellitus.
The blueberry juice used in the study was not standard juice but had undergone a transformation using the Serratia vaccinii bacterium.
“Results of this study clearly show that biotransformed blueberry juice has strong anti-obesity and anti-diabetic potential,” said lead researcher Pierre Haddad, from the Université de Montréal.
“Biotransformed blueberry juice may represent a novel therapeutic agent, since it decreases hyperglycemia in diabetic mice and can protect young pre-diabetic mice from developing obesity and diabetes.”
Blueberries, nature’s only ‘blue’ food, are a rich source of polyphenols, potent antioxidants that include phenolics acids, tannins, flavonols and anthocyanins.

Caution on mix of cholesterol-lowering meds →
Sept 1, 2009 (Cbc.ca)—Combining a prescription cholesterol-lowering medication with omega-3 supplements may not be the best approach, a new review suggests.
Statins are medications that prevent the liver from producing cholesterol, which can help reduce the risk of heart attacks. Every year, Canadian doctors write more than 12 million prescriptions for statins, making them the most-prescribed drugs in the country. Omega-3’s are heart-healthy oils that some evidence suggests help reduce the risk of coronary disease.
In the Nov. 3 issue of the Annals of Internal Medicine, Dr. Mukul Sharma, medical director of the Regional Stroke Centre at the Ottawa Hospital, and his team reviewed five different cholesterol-lowering medications that can be combined as well as omega-3 supplements sold over the counter. They concluded there is little evidence to support mixing them.
Bad cholesterol increase
In one case, the researchers found taking prescription medication with omega-3 had the opposite effect.
“Your bad cholesterol, the LDL, actually goes up,” Sharma said. “There isn’t a benefit in terms of heart disease, stroke or mortality.”
Most cholesterol patients may be better off taking higher doses of one drug instead of multiple medications, since there may be less chance of side-effects and long-term problems developing, he said. People are also less likely to take their medications the more that are prescribed.

How Much Omega-3 Fatty Acid Do We Need To Prevent Cardiovascular Disease? →
Sept 1, 2009 (Sciencedaily.com)—A team of French scientists have found the dose of DHA (docosahexaenoic acid) that is “just right” for preventing cardiovascular disease in healthy men. In a research report appearing in the September 2009 print issue of The FASEB Journal, the scientists show that a 200 mg dose of DHA per day is enough to affect biochemical markers that reliably predict cardiovascular problems, such as those related to aging, atherosclerosis, and diabetes. This study is the first to identify how much DHA is necessary to promote optimal heart health.
“This study shows that regularly consuming small amounts of DHA is likely to improve the health status of people, especially in regards to cardiovascular function,” said Michel Lagarde, co-author of the study.
To determine the optimal dose of DHA, Lagarde and colleagues examined the effects of increasing doses of DHA on 12 healthy male volunteers between ages of 53 and 65. These men consumed doses of DHA at 200, 400, 800, and 1600 mg per day for two weeks for each dose amount, with DHA being the only omega-3 fatty acid in their diet. Blood and urine samples were collected before and after each dose and at eight weeks after DHA supplementation stopped. The researchers then examined these samples for biochemical markers indicating the effects of each dose on the volunteers.
“Now that we have a very good idea about how much DHA is just right, the next step is to try it out in an expanded clinical trial that involves many more people,” said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. “Until then, I’ll stick with tasty foods that contain DHA, like fish, rather than getting a quick fatty-acid fix at the local vitamin store.”

Surprising Rate Of Recurring Heart Attacks, Strokes Globally →
Aug 31, 2009 (Sciencedaily.com)—Despite many medicines and other treatments for patients with vascular disease, a large international study shows these patients have a surprisingly high rate of recurring events such as strokes, heart attacks and hospitalizations as well as mortality.
Also unexpected: patients in North America (including the U.S.) experienced an above-average rate of these events. Patients in Eastern Europe had the highest rate, and those in Australia and Japan had the lowest.
The results from the international REACH (Reduction of Atherothrombosis for Continued Health) Registry, presented by a researcher from Northwestern University Feinberg School of Medicine, examined data for 32,247 patients one and three years after they enrolled in the registry. Patients who had symptomatic vascular disease had a 14.4 percent rate at one year and 28.4 percent rate at three years of having a heart attack, stroke, rehospitalization for another type of vascular event or vascular death. Patients with vascular disease in more than one location of the body had the highest event rate at 40.5 percent at three years.
When projected over the global population who would mirror the patients in REACH, this represents millions of serious vascular events occurring every few years, many of which could be prevented.
“We were surprised by the high rate of these recurring vascular events,” said lead author Mark J. Alberts, M.D., professor of neurology at the Feinberg School and director of the stroke program at Northwestern Memorial Hospital. “We know how to prevent vascular disease and the events that it produces. This points to the need for better prevention, better use of medications and a need to develop more potent medications. These are the number one and two causes of death throughout the world.”

Exercise beats angioplasty: heart experts →
Aug 31, 2009 (Cbc.ca)—Working up a sweat may be even better than angioplasty for some heart patients, experts say.
Studies have shown heart patients benefit from exercise, and some have shown it works better than surgical procedures. At a meeting of the European Society of Cardiology in Barcelona on Sunday, several experts said doctors should focus more on persuading their patients to exercise rather than simply doing angioplasties.
Angioplasty is the top treatment for people having a heart attack or hospitalized with worsening symptoms. It involves using a tiny balloon to flatten a blockage and propping the heart artery open with a mesh tube called a stent. Most angioplasties are done on a non-emergency basis, to relieve chest pain caused by clogged arteries cutting off the heart’s blood supply.
“It’s difficult to convince people to exercise instead of having an angioplasty, but it works,” said Rainer Hambrecht of Klinikum Links der Weser in Bremen, Germany.
Hambrecht published a study in 2004 that found that nearly 90 per cent of heart patients who rode bikes regularly were free of heart problems one year after they started their exercise regimen. Among patients who had an angioplasty instead, only 70 per cent were problem-free after a year.

Natural Therapies: Simple Solutions for Complex Problems →
Aug 31, 2009 (NaturalNews.com)— One question I’m routinely asked is “If you had to recommend just one supplement for __________ (fill in the blank), what would it be?” I could easily spout off a laundry list of safe, natural therapies for virtually all common health concerns. Narrowing it down to only one therapy per condition is much more of a challenge, but based on recent patient and subscriber feedback, here goes.
Manage Pain With MSM
For joint and muscle pain, I’ve been hearing great things about MSM (methylsulfonylmethane), a naturally occurring sulfur compound and close chemical cousin of DMSO-that doesn’t have DMSO’s obnoxious smell. MSM relieves pain by several mechanisms. It’s a powerful anti-inflammatory, it blocks the pain response in nerve fibers, and its sulfur may help with cartilage regeneration.
One of our patients, the mother of a Whitaker Wellness doctor, was bothered by nagging pain in her neck and shoulders- until she started taking MSM. Another patient, who is an actor, used to have such excruciating pain in his knees that he’d have to take Vicodin before going on stage and was considering arthroscopic surgery. He reported miraculous results with MSM and no longer requires painkillers. The suggested daily dose of MSM ranges between 1,200 and 6,000 mg. Start low and increase as needed.
How to Get a Good Night’s Sleep
Occasional sleeplessness is a very common concern. I used to recommend melatonin, a hormone that helps regulate your “body clock”; valerian, an herb with mild sedative effects; or L-theanine, an amino acid with profound relaxing properties. Each of these worked for some people, but not everyone. Then I tried them in combination, and bingo! For the majority of patients and subscribers, this combo engenders a good night’s sleep.
Tom, a VP at the company that publishes Health & Healing, shared his story. He was eating right, exercising, and taking vitamins, but when it came time for bed, despite the fact he was physically and mentally drained, he still sometimes had trouble falling or staying asleep. Since he started taking this supplement, however, he sleeps like a baby.
Look for combination sleep products in your health food store. Suggested doses are 1,000 mcg melatonin, 500 mg valerian extract, and 200 mg L-theanine 30 minutes to an hour before bedtime.
V8 Gives Hypertension the Boot
Experts predict that an astounding 90 percent of middle-aged Americans will develop hypertension at some point in their lives. This sounds extreme, but I have to admit that many of the patients who come to my clinic have high blood pressure. Fortunately, we are very successful at getting them off drugs with diet changes, exercise, and a handful of supplements. But if I had to select just one thing for high blood pressure it would be Low Sodium V8 Juice.
Low Sodium V8 has a slight blood-thinning effect, which reduces pressure on the arteries, and it’s loaded with potassium, which balances sodium and helps lower blood pressure. One of the many patients who has benefited from this therapy is Ted, an old friend of mine. After struggling with hypertension for years, Ted took me up on my suggestion to drink 12 ounces of this juice every day. Much to his surprise, this simple step worked to normalize his blood pressure.

Obesity Is A Poor Gauge For Detecting High Cholesterol Levels In Children →
Aug 29, 2009 (Sciencedaily.com)—With the epidemic of childhood obesity in the United States, there is concern that overweight and obese children need to be screened for chronic medical conditions, including high cholesterol levels.
However, body fat is not an effective indicator of high cholesterol in children, according to new University of Michigan research.
Those are the findings of a U-M study led by U-M pediatricians Joyce Lee, M.D., MPH, and Matthew Davis, M.D., MAPP, which will appear in the August 3 edition of the Archives of Pediatric and Adolescent Medicine.
“We found, actually, that using body mass index to find kids with high cholesterol does not work well. There were many overweight and obese kids who had normal cholesterol, and there were a fair number of healthy-weight kids who had high cholesterol,” says Lee, a member of the Child Health Evaluation and Research (CHEAR) Unit in the U-M Division of General Pediatrics, and assistant professor in the Department of Pediatrics and Communicable Diseases at the U-M Medical School.

Snooze longer, you may live longer →
Brunch at 10? Make it 11. As if not having circles under your eyes weren’t a compelling enough reason to get enough sleep, here’s another: You’ll be less likely to age from diabetes, the makes-you-sick-and-tired disease that affects more than 2 million Canadians.
When researchers let people sleep just 5 1/2 hours a night for two weeks, they saw that the sleep-deprived folks had started to develop diabetes; they had increased insulin resistance and reduced glucose tolerance.
What does that mean? Basically, your body has mailmen that take energy from food and place it inside the mailbox in your cells. But with diabetes or insulin resistance, those mailmen can’t get the mail inside.
So glucose, like a posse of bored teenagers, hangs out in your bloodstream and causes all kinds of trouble. That’s dangerous to your arteries, your brain, your immune system and your kidneys.
Previous research saw the risk for developing diabetes go up with far less sleep, but these scientists decided to test a more realistic scenario of 5 1/2 hours (sound familiar?).
Too busy to get to bed earlier? No, you’re not, especially since your life depends on it!. Try inching up your bedtime by 10 little minutes a night. By this time next week, you may have dropped your risk of aging from diabetes.

Strong Thighs May Mean Less Knee Pain for Women →
Aug 28, 2009 (Therapytimes.com)—Stronger thigh muscles can help protect women, but not men, from the pain of arthritic knees, a new study finds.
The knee is the most common joint affected by osteoarthritis or degenerative joint disease, a major cause of disability in the United States, researchers say. In the United States, nearly 27 million adults suffer from osteoarthritis, and 16% of cases in people aged 45 and older affect the knee. Almost 19% of symptomatic knee osteoarthritis patients are women and 13.5% are men, according to the U.S. Centers for Disease Control and Prevention.
However, the new study finds that “stronger quadricep [thigh] muscles may protect older adults from developing the combination of osteoarthritis on X-ray and daily pain or stiffness in their knees,” said lead researcher Dr. Neil Segal, director of the Clinical Osteoarthritis Research Program at the University of Iowa.
“We already knew that quadriceps strength was associated with better ability to walk and get up from a chair,” Segal said. “However, one implication of these new findings is that quadricep strength may protect against developing symptomatic knee osteoarthritis.”

Defend Against Disease with Broccoli Juice →
Aug 28, 2009 (NaturalNews.com)— Broccoli is a member of the cauliflower family or a Brassica. It is a diverse super food that is delicious when steamed or can be finely chopped and sprinkled on food for added nutrition. Juicing is a great way to get the most out of this amazing food. By drinking broccoli juice daily, we can prevent disease and transform our health.
Broccoli juice offers a whole array of amazing benefits that help us to enjoy optimum health. It contains glucoraphanin that converts into sulphoraphane, a powerful anticancer agent. It contains isothyocyanate, the chemical that activates our natural cancer inhibiting genes. The sprouted seeds and the broccoli juice help to fight prostate cancer. It contains compounds that help to detox the liver from cancer causing toxins.
With high levels of selenium and fiber, the juice of Broccoli offers protection from stomach and bowel cancer.
Broccoli juice contains compounds that protect cells from ultraviolet light. It helps to increase the production of protective enzymes that protect cells against different aspects of UV damage by working inside the cells. It helps in prevention of skin cancer.
Glucoraphanin present in the broccoli juice promotes antioxidant defenses in the body that help lower blood pressure and harmful inflammation in the heart and arteries.
The phytochemical sulforaphane helps the body defend against H. pylori, a bacteria that causes gastrointestinal problems. Thus, it helps to prevent stomach ulcers and painful bloating.
Broccoli juice contains fibers which help to maintain a healthy gastrointestinal GI tract. It reduces cholesterol levels in the blood. Calcium present in the Broccoli juice promotes healthy bones and helps to burn fat. It decreases the production of cortisol, which is a stress hormone, relating to food cravings and stomach fat.

Consumers Duped by Trans Fat Labeling →
Aug 28, 2009 (NaturalNews.com)— FDA food labeling rules make it possible for consumers to exceed their maximum recommended daily intake of trans fats even if they eat only foods labeled “zero trans fats” per serving.
Trans fats, also known as hydrogenated oils, are synthetically produced by adding hydrogen atoms to unsaturated vegetable oils. Unlike natural unsaturated or saturated fats, trans fats have no nutritional value. They have been overwhelmingly shown to increase the risk of death from cardiovascular disease, such that several large cities and the state of California have banned their use in restaurants.
The fats are favored by food producers because they have a longer shelf life than natural fats. But growing consumer awareness over the dangers of trans fats has led more and more people to avoid them. According to a recent survey by Greenfield Online, 72 percent of U.S. residents read nutritional labels to make food purchasing decisions, and 61 percent believe that “zero trans fats” is the most important claim for a heart-healthy food.
Yet because the FDA allows nutrient content to be rounded to the nearest half gram, all food producers need to do to make a “zero trans fats” claim is set the serving size low enough that it contains no more than 0.49 grams of trans fats.

Swimming Aids Asthma Symptoms In Children, Study Finds →
Aug 27, 2009 (Sciencedaily.com)—Research has shown that swimming aids asthma symptoms in children. The activity has been proven to be an effective non-pharmacological intervention for children and adolescents, according to a study in Respirology, published by Wiley-Blackwell.
Researchers divided children between the ages of seven to twelve into two groups. One group underwent a six-week swimming program in addition to their regular asthma treatments. All of the children in the experimental program showed significant improvement in all clinical variables including symptoms, hospitalizations, emergency room visits and school absenteeism.
Other improvements included asthma severity, mouth-breathing, snoring, chest deformity, self-confidence and general feelings of disadvantage.
“Unlike other sports, swimming is unlikely to provoke asthma attacks. In addition to improving asthma, swimming promotes normal physical and psychological development, such as increasing lung volume, developing good breathing techniques and improving general fitness,” said lead author, Wang Jeng-Shing from the Taipei Medical University.
He added, “Not only is swimming an excellent form of exercise for children with asthma, the health benefits reaped continued to be observed for at least a year after the completion of the swimming program.”
