Low Vitamin D Levels Increase Risk of High Blood Pressure

People with low blood levels of vitamin D are at increased risk of higher blood pressure - a problem that could be easily remedied with sun exposure or vitamin D supplementation, says a new study.

The researchers report that non-Hispanic whites had the highest vitamin D blood levels, followed by Mexican Americans, while non-Hispanic blacks had the lowest vitamin D levels.

A recent review of the science reported that the tolerable upper intake level for oral vitamin D3 should be increased five-fold, from the current tolerable upper intake level (UL) in Europe and the US of 2000 International Units (IU), equivalent to 50 micrograms per day, to 10,000 IU (250 micrograms per day).

Omega-3 Rich Fish Oil Reduces Inflammation, Vegetable Oil Increases Inflammation

Using more fish oil than vegetable oil in the diet decreases the formation of chemicals called prostanoids, which, when produced in excess, increase inflammation in various tissues and organs.

"Prostanoids help control blood pressure, fight allergies, and modulate inflammation, but too much of them especially those made from vegetable oils, can also lead to increased pain, swelling, and redness in various tissues," wrote the researchers.

Smith and his colleagues hope that by further investigating how prostanoids are regulated in the body, they can design potential drugs that bind to COX-2 and decrease levels of the vegetable oil prostanoids. Who is it that thinks it is better to design and give you drugs instead of just recommending a healthy diet consisting of more fish rich in omega-3's than unnatural vegetable oils rich in omega-6 PUFA's?

Cinnamon Helps Manage Blood Sugar Levels

Researchers found that compared to placebo, the addition of cinnamon to the rice pudding “significantly delayed gastric emptying and lowered the [post-meal blood sugar levels]”. No significant effects were seen however, in improving feelings of fullness in the cinnamon group.

The researchers concluded “the intake of 6 g cinnamon with rice pudding reduces postprandial blood glucose and delays gastric emptying without affecting [fullness].”

Magnesium Intake Up, Diabetes Risk Down

Eating more magnesium-rich foods, like green leafy vegetables and nuts, may reduce the risk of type-2 diabetes, suggests a meta-analysis of observational studies. The analysis of prospective cohort studies reports that for every 100 milligram increase in magnesium intake, the risk of developing type-2 diabetes decreased by 15 percent.

Earlier dietary surveys show that a large portion of adults do not even meet the RDA for magnesium.

"The potential protective role of magnesium intake against type-2 diabetes may be due to improvement of insulin sensitivity," said the reviewers.

Ritalin May Affect Children's Brain Development

Use of the attention deficit/hyperactivity disorder (ADHD) drug Ritalin by young children may cause long-term changes in the developing brain, suggests a new study of very young rats by a research team at Weill Cornell Medical College in New York City.

The study is among the first to probe the effects of Ritalin (methylphenidate) on the neurochemistry of the developing brain. This should serve as a warning for some and a reminder for others that powerful drugs may be approved for use, even by children, with very little testing. Between 2 to18 percent of American children are thought to be affected by ADHD, and Ritalin, a stimulant similar to amphetamine and cocaine, remains one of the most prescribed drugs for the behavioral disorder. No comment should even be needed here.

There are much safer alternatives such as increasing Omega-3 polyunsaturated fatty acids from fish and krill oil, decreasing Omega-6 oil from margarine, vegetable oils and processed foods (such as potato and tortilla chips, energy bars, fried foods and salad dressings), and the elimination of sugar from kids diets.

Reducing Insulin Signaling in the Brain Can Prolong Lifespan

One route to a long and healthy life may be establishing the right balance in insulin signaling between the brain and the rest of the body.

Studies show that reducing insulin signaling lengthens lifespan. But in humans and rodents, reducing insulin signaling often causes diabetes. “The easiest way to keep insulin levels low in the brain,” White says, “is old-fashioned diet and exercise.”

The study also calls into question the long-term effects of insulin therapy for diabetes, White adds. “High insulin should be the short term solution to insulin resistance, because it might damage the brain in the long run,” he says. Better treatments for diabetes and healthy aging, he suggests, should concentrate on sensitizing the body’s cells to low amounts of insulin.

Low Vitamin D Levels Increase Syndrome X Risk

Low blood levels of vitamin D increase the risk of developing syndrome X among obese people, suggests a new study from Spain.

Syndrome X is a condition characterized by central obesity, hypertension, and disturbed glucose and insulin metabolism. The syndrome has been linked to increased risks of both type-2 diabetes and cardiovascular disease. Fifteen percent of adult Europeans are estimated to be affected by syndrome X, while the US statistic is estimated to be a whopping 32 percent.

It was also observed that blood levels of HDL-cholesterol were lower (37. mg/dl vs. 44.9 mg/dl), and triglycerides levels were higher (163.3 mg/dl vs. 95.1 mg/dl) in the vitamin D-deficient group compared to the vitamin D-sufficient group.

Vitamin K Deficiency More Common Than Thought

Many apparently healthy people may be vitamin K deficient, says a new review, potentially increasing the risk of bone loss and also for arterial calcification.

"Poor vitamin K status must be regarded as a serious risk factor for increased postmenopausal bone loss and for artery calcification, notably in diabetes, endstage renal disease and aging," wrote the authors. Cranenburg and co-workers added that several clinical trials have reported the benefits of supplementary vitamin K for decreasing bone loss, as well as in maintenance of bone strength and carotid artery elasticity.

Omega-3 and Antioxidants Reduce Asthma Risk

A diet rich in fruit, vitamins C and E, and omega-3 fatty acids may reduce the risk of respiratory conditions like asthma, chronic bronchitis symptoms, and wheezing, reports a new study.

The dynamics of our young population are in itself troubling. The researchers recruited 2,112 students aged 16 to 18 in 12 communities around the US and Canada. In the group 33 percent were overweight, 72 percent did not consume multivitamins, and about 25 percent were daily smokers.

"A balanced diet is not only good for lung health, but for general health. Parents and physicians should work together to monitor and maintain healthy diets and lifestyles for children of all ages."

90% of African-American Kids Have Low Vitamin D Levels

About 55 percent of seemingly healthy adolescents may be vitamin D deficient, says a US study, and are at increased risk of osteoporosis and other health problems later in life. Among African-American adolescents the proportion of children with low vitamin D levels was over 90 percent, said the researchers.

A similar study from Britain last year reported that over 70 percent of seemingly healthy teenage girls might be vitamin D deficient. Vitamin D refers to two biologically inactive precursors - D3, also known as cholecalciferol, and D2, also known as ergocalciferol.

Calcium and Vitamin D Increase Bone Mineral Density in Elderly

Supplementation with vitamin D and calcium reduces bone loss in patients with recent osteoporotic fractures, reports a new study from Denmark.

Patients were randomly assigned to receive 3000 mg calcium carbonate plus 1400 IU vitamin D-3 (cholocalciferol), or placebo (200 IU cholecalciferol) for one year. Researchers said vitamin D levels increase from 33 to 82 nmol/L in the active group. Bone turnover also decreased as a result of intervention.

"A one-year intervention with calcium and vitamin D reduced bone turnover, significantly increased BMD in patients younger than 70 years, and decreased bone loss in older patients," concluded the researchers.

Omega-3 EPA and DHA Protect Against Colorectal Cancer

Increased intake of omega-3 fatty acids from marine source, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), protects against colorectal cancer.

Consumption of omega-3 polyunsaturated fatty acids was associated with a 37 percent reduction of colorectal cancer risk, comparing highest against lowest average intakes. Increased intake of EPA was associated with a 41 percent reduction in risk, while DHA was associated with a 37 percent reduction in risk, comparing highest against lowest average intakes.

Metabolism of fatty acids produces compounds called prostaglandins, which can be either pro- or anti-inflammatory. The prostaglandins derived from omega-3 fatty acids are said to be anti-inflammatory and may protect against the development of cancer, while prostaglandins derived from omega-6 fatty acids, like AA, are proposed to be pro-inflammatory.

66% of Adults, 80% of Black Women Are Overweight or Obese

The U.S. obesity prevalence increased from 13 percent to 32 percent between the 1960s and 2004, according to researchers at the Johns Hopkins Bloomberg School of Public Health Center for Human Nutrition.

“Obesity is a public health crisis. If the rate of obesity and overweight continues at this pace, by 2015, 75 percent of adults and nearly 24 percent of U.S. children and adolescents will be overweight or obese.”

Calcium and Vitamin D Reduce Cancer Risk

Past studies have established links between calcium and cancer and vitamin D and cancer. This study confirms that a minimum of 1000 IU vitamin D taken with calcium supplementation will reduce cancer risk.

Calcium alone appears to reduce the relative risk of cancers about 17%. The addition of vitamin D reduced the relative risk of cancer incidence almost 56%, when the first year cancers were eliminated.

This study supports the theory that calcium supplementation as well as vitamin D status is important in reducing cancer risk. This study indicates that 1000 IU per day vitamin D taken with calcium supplementation may improve immune status, however it does not establish a minimum level for optimum health.

Low Vitamin D Levels May Be Common in Otherwise Healthy Children

Many otherwise healthy children and adolescents have low vitamin D levels. African American children, children above age nine and with low dietary vitamin D intake were the most likely to have low levels of vitamin D in their blood, according to researchers from The Children’s Hospital of Philadelphia.

Researchers found that more than half of the children had low blood levels of vitamin D. Of the subjects, 55 percent of the children had inadequate vitamin D blood levels and 68 percent overall had low blood levels of the vitamin in the wintertime.

In addition to musculoskeletal effects, vitamin D is important for immune function, and low blood levels of the vitamin may contribute to diseases such as hypertension, cancer, multiple sclerosis and type 1 diabetes. Decreased blood levels of vitamin D have also been linked to obesity.

Medication Errors are the 4th Leading Cause of Death

It’s the fourth leading cause of death among North Americans and costs billions of dollars each year in unnecessary health expenses, just for Canadian seniors alone. A Dalhousie University researcher is tackling the widespread issue of medication errors.

Resulting problems from medication errors, such as adverse drug reactions, are the fourth-leading cause of death in Canada and the U.S. Dr. MacKinnon co-authored a study that estimated the cost of preventable adverse drug-related outcomes in Canada’s seniors to be $11 billion per year.

“We spend more on drugs in Canada than we do on physicians or medical equipment. Drugs are also the fastest growing component of health budgets."

Pomegranate Juice Reduces Erectile Dysfunction

A glass of pomegranate juice every day may help manage erectile dysfunction, suggest results from a randomized, placebo-controlled, double-blind, crossover pilot study.

Researchers from The Male Clinic, Beverly Hills, and University of California, Los Angeles report that 47 percent of subjects reported erections improvements as a result of pomegranate juice.

Researchers believe that the results might be due to the potent antioxidant content of pomegranate juice, which can prevent free radical molecules from disrupting proper circulatory function.

Sun Exposure No Guard Against Low vitamin D

In many people, vitamin D levels can remain low despite abundant exposure to sunlight, new research shows.

The 93 participants in the study spent an average 22.4 hours per week outside without sunscreen and 28.9 hours per week outside with and without sunscreen.

Despite this abundant sun exposure, 51 percent of these individuals were found to have low vitamin D levels, the researchers found.

Omega-3 Protects Against Retinopathy

Omega-3 fatty acids may protect our eyes against the development and progression of retinopathy, a deterioration of the retina.

The study adds further support for increasing the ratio of omega-3 to omega-6 fatty acids with the finding that omega-6 fatty acid consumption from margarine, corn and other vegetable oils, salad dressing and more is associated with an increased risk of retinopathy.

Mice on the omega-3 diet, rich in DHA (docosahexaenoic acid) and its precursor EPA (eicosapentaenoic acid), were found to have 40 to 50 percent less initial vessel loss in the retina than the omega-6-fed mice. As a result, the omega-3 group had a 40 to 50 percent decrease in pathological vessel growth.
