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.

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.

AHA limits sugar intake to protect heart →
Aug 27, 2009 (Presstv.com)—While Americans eat more than 22 teaspoons of sugar per day, the American Heart Association urges individuals to limit their sugar intake in order to remain healthy.
“For the first time we’ve created specific recommendations about the amount of sugars that can be consumed in a heart-healthy diet,” said Rachel Johnson lead author of a report published in Circulation.
According to the report, too much sugar not only leads to obesity but also places the individual at a greater risk of developing diabetes, high blood pressure, heart disease and stroke.
The new guidelines revealed that women should eat less than 100 calories (equal to six teaspoons or 25 grams) of added processed sugar per day.
The limit for moderately active women aged 51-55 is as low as 5 teaspoons (80 calories) and for sedentary women aged 71-75 is as low as 3 teaspoons (48 calories).
As for men, the permitted sugar amount is reported to be less than 150 calories, equal to nine teaspoons or 37.5 grams.
The new guidelines recommend active men aged 21-25 to eat less than 18 teaspoons (288 calories) and sedentary men aged 46-50 to eat less than 9 teaspoons (144 calories).
AHA officials say that the guidelines are only for “added sugars” used to make foods and drinks rather than the natural sugar found in fruits, vegetables, whole grains, or milk.
They therefore urged food and beverage companies to limit the sugar content of their products.

More Obesity Blues: Obese People Are At Greater Risk For Developing Alzheimer's, Study Finds →
Aug 25, 2009 (Sciencedaily.com)—Obesity is on a rampage, with the World Health Organization pegging the numbers at more than 300 million worldwide, with a billion more overweight. With obesity comes the increased risk for cardiovascular disease, Type II diabetes, and hypertension.
Now comes more discouraging news. In the current online edition of the journal Human Brain Mapping, Paul Thompson, senior author and a UCLA professor of neurology, and lead author Cyrus A. Raji, a medical student at the University of Pittsburgh School of Medicine, and colleagues compared the brains of people who were obese, overweight, and of normal weight, to see if they had differences in brain structure; that is, did their brains look equally healthy.
They found that obese people had 8 percent less brain tissue than people with normal weight, while overweight people had 4 percent less tissue. According to Thompson, who is also a member of UCLA’s Laboratory of Neuro Imaging, this is the first time anyone has established a link between being overweight and having what he describes as “severe brain degeneration.”
“That’s a big loss of tissue and it depletes your cognitive reserves, putting you at much greater risk of Alzheimer’s and other diseases that attack the brain,” said Thompson. “But you can greatly reduce your risk for Alzheimer’s, if you can eat healthily and keep your weight under control.”

Prehypertension, Obesity And Kidney Disease Risks →
Aug 11, 2009 (Sciencedaily.com)—People with prehypertension are not at increased risk of kidney disease if their body mass index (BMI) is under 30.0 kg/m2, a first-ever examination of the combined effect of blood pressure and body weight on the risk of kidney disease shows.
The study was by a team of medical researchers at the Norwegian University of Science and Technology (NTNU).
Prehypertension is a relatively new medical classification introduced in 2003 in the Seventh Report of the Joint National Committee on High Blood Pressure (JNC-7), and is defined as systolic blood pressure of 120 to 139 mm Hg or diastolic BP of 80 to 89 mm Hg. Studies from the United States and Asia have shown that prehypertension can increase the risk of serious kidney disease, but because more than 30 percent of the US and European populations can be classified as prehypertensive, treating everyone with this condition would be an enormous undertaking, the researchers observed.
At the same time, obesity is also known to lead to end-stage renal disease (ESRD) and death from chronic kidney disease (CKD) as a result of diabetes and hypertension. These increased risks have led medical researchers to consider whether people with prehypertension should be considered for treatment if they have other cardiovascular risks, such as obesity.

Dementia risk higher in middle-aged smokers →
Aug 4, 2009 (Presstv.com)—Middle-aged individuals, who smoke and have high blood pressure or diabetes, are placed at a considerable increased risk of developing dementia.
According to a study published in the Journal of Neurology, Neurosurgery and Psychiatry, smoking, diabetes and hypertension are major risk factors contributing to dementia in the long run.
Smokers under the age of 55 are five times more likely to develop dementia. As for diabetics, however, the risk is tripled.
Smoking, high blood pressure and diabetes can damage the brain and its nourishing small blood vessels, leading to dementia.
Scientists therefore pointed out the importance of early lifestyle changes and risk factor treatment to prevent dementia.

TV And Computer Screen Time May Be Associated With High Blood Pressure In Young Children →
Aug 4, 2009 (Sciencedailycom)—Sedentary behaviors such as TV viewing and “screen time” involving computer use, videos and video games appear to be associated with elevated blood pressure in children, independent of body composition, according to a report in the August issue of Archives of Pediatrics & Adolescent Medicine.
The recent trend in obesity is a major public health concern and its effect on blood pressure is of particular concern, according to background information in the article. “The clustering of cardiovascular disease risk factors in overweight youth suggests that risks may be immediate and not just indicative of potential future problems,” the authors write. Although elevated blood pressure is associated with genetic factors, healthy physical, dietary and sleep habits seem to be relevant contributors to blood pressure levels in children. However, there have not been any clear links between sedentary behavior and elevated blood pressure in children younger than age 9.

Reducing Salt Intake Can Lower Blood Pressure →
July 29, 2009 (Sciencedaily.com)—Adults who use less salt in their diet can experience a slight reduction in their blood pressure in the medium term. However, whether in the long term this can also reduce the risk of late complications in people with sustained high blood pressure, otherwise known as essential hypertension, and whether in the long term their anti-hypertensive medication can be reduced remains unresolved. This is the conclusion of the Institute for Quality and Efficiency in Health Care (IQWiG) in its final report published in the form of a rapid report on 20 July 2009. This rapid report is part of a package commissioned by the Federal Joint Committee (G-BA), in which the benefit of various non-drug treatment strategies for high blood pressure are to be assessed. Stress management and more physical activity are also included, as well as giving up smoking and cutting down alcohol consumption. IQWiG has already completed a report on the effect of weight reduction on blood pressure. For full article see link above.

Chocolate powder may slash blood pressure: Study →
July 22, 2009 (Nutraingredients.com)—Consumption of a commercially available cocoa powder, enriched in flavonoids, may decrease blood pressure and boost heart health, suggests a new study with rats.
Rodents fed 300 milligrams per kilogram of body weight experienced a reduction in blood pressure similar to a 50 mg/kg dose of Captopril, a well-known pharmaceutical anti-hypertensive, according to findings published in the Journal of Agricultural and Food Chemistry.
“This is important because this drug is known to be a very effective antihypertensive treatment in clinical practice and spontaneously hypertensive rats represent nowadays the best experimental model for essential hypertension in humans,” wrote the researchers, led by Amaya Aleixandre from the Faculty of Medicine at the Universidad Complutense in Madrid.
The study used Natraceutical’s CocoanOX and was funded by the company. The cocoa powder is a rich source of flavonoids, with a reported 139 milligrams of polyphenols per gram of cocoa powder, 129 milligrams of which are procyanidins, according to the new report.
The health benefits of antioxidant-rich chocolate have received much recognition in recent years, with positive findings from a number of studies impacting on consumer awareness. Chocolate manufacturers are using high cocoa content (over 70 per cent) as a means of differentiation, and cocoa has also received attention for its potential in functional food applications.
“We have demonstrated the antihypertensive properties of the industrially processed natural flavonoid-enriched cocoa powder named CocoanOX,” wrote the researchers.
“The results obtained suggest that this product could be used as a functional food ingredient with potential therapeutic benefit in the prevention and treatment of hypertension.”

Risk Factors Of Cardiovascular Disease Rising In Poor, Young →
July 22, 2009 (Sciencedaily.com)—Cardiovascular disease is increasing in adults under 50 and those of lower socioeconomic status, despite recent trends which show that cardiovascular disease is declining in Canada overall, say researchers at the Peter Munk Cardiac Centre. Untreated cardiovascular disease can lead to heart failure, coronary artery disease and death, and is the most common cause of hospitalization in North America.
By exploring national trends in heart disease, hypertension, diabetes, obesity and smoking prevalence from 1994-2005, researchers found that cardiovascular disease is on the rise in adults under 50 and those of lower socioeconomic status according to a study published in the July edition of the Canadian Medical Association Journal.
“Our results indicate that young people are increasingly bearing the burden of cardiovascular risk factors,” says Dr. Douglas Lee, cardiologist and scientist at the Institute for Clinical Evaluative Sciences (ICES). “This is an important group because they are the ones who will predict future heart disease, and earlier onset of cardiovascular disease means potentially longer and more intense treatment over their lifetime.”
The study, called “Trends in risk factors for cardiovascular disease in Canada: temporal, socio-demographic and geographic factors,” sampled Canadians aged 12 years and older from all socioeconomic and ethnic groups. The prevalence of heart disease and diabetes is rising fastest among Canadians of lower socioeconomic status, who also tend to have the highest cardiovascular risk profiles. The prevalence of hypertension and obesity is increasing in nearly all Canadians, but is rising fastest in those with higher incomes.

No Benefit in Lowering BP Below "Standard" 140/90 mm Hg →
July 10, 2009 (Medscape.com)— A new review has found that lowering blood pressure below the “standard” target of 140/90 mm Hg is not beneficial in terms of reducing mortality or morbidity [1]. Dr Jose Agustin Arguedas (Universidad de Costa Rica, San Pedro de Montes de Oca) and colleagues report their findings online July 8, 2009 in the Cochrane Database of Systematic Reviews.
They explain that over the past five years, a trend toward lower targets has been recommended by hypertension experts who set treatment guidelines, “based on the assumption that the use of drugs to bring the BP lower than 140/90 mm Hg will reduce heart attack and stroke.” But this approach “is not proven,” they point out.
Arguedas told heartwire that they reviewed seven trials with more than 22 000 subjects comparing lower or standard diastolic BP targets, but they were unable to identify any studies comparing different systolic BP targets. “We found there is no evidence that reaching a target of below 90 mm Hg diastolic BP will provide additional clinical benefit, but we can’t say whether lowering systolic BP below 140 mm Hg will be beneficial or not; there are no data.”

Bran may slash hypertension risk: Study →
July 10, 2009 (Nutraingredients.com)—Increased intakes of whole grains, and bran in particular, may reduce the incidence of hypertension in men, according to new findings from Harvard.
Data from over 30,000 men participating in the Health Professionals Follow-Up Study indicated that increased intakes of whole grains are associated with a 19 per cent lower incidence of hypertension.
The researchers, led by Alan Flint from Harvard School of Public Health, report their findings online in the American Journal of Clinical Nutrition.
“These findings have implications for future dietary guidelines and prevention of hypertension,” they wrote.

Component Of Vegetable Protein May Be Linked To Lower Blood Pressure →
July 6, 2009 (Sciencedaily.com)—Consuming an amino acid commonly found in vegetable protein may be associated with lower blood pressure, researchers report in Circulation: Journal of the American Heart Association.
Researchers found that a 4.72 percent higher dietary intake of the amino acid glutamic acid as a percent of total dietary protein correlated with lower group average systolic blood pressure, lower by 1.5 to 3.0 millimeters of mercury (mm Hg). Group average diastolic blood pressure was lower by 1.0 to 1.6 mm Hg.
Systolic blood pressure is the force when the heart beats; diastolic pressure is the pressure when the heart rests between beats.
This average lower blood pressure seems small from an individual perspective. But, on a population scale, it represents a potentially important reduction, said Jeremiah Stamler, M.D., lead author of the study.
“It is estimated that reducing a population’s average systolic blood pressure by 2 mm Hg could cut stroke death rates by 6 percent and reduce mortality from coronary heart disease by 4 percent,” said Stamler, professor emeritus of the Department of Preventive Medicine in the Feinberg School of Medicine at Northwestern University in Chicago, Ill.
