Vitamin D beneficial for more than strong bones
Jun 23, 2016

JOHNSON CITY (June 23, 2016) – Two scientists at East Tennessee State University’s Quillen College of Medicine led an international research team that recently discovered vitamin D may be able to reduce soft tissue calcification.

“We know we need vitamin D for strong bones, especially during older age when osteoporosis sets in,” said Dr. Matt Keasey, a research associate in the Department of Biomedical Sciences working with Dr. Theo Hagg, chair of the Department of Biomedical Sciences, as members of the research team. “This new study suggests that it also reduces regular age-related soft tissue calcification in arteries and the brain.”

Soft tissue calcification is relatively common in the elderly, with arteries being particularly vulnerable and the brain also being vulnerable as individuals age, Hagg added.

Its Time to Rethink Sun Avoidance
Jun 10, 2016

Now that the summer sun is here, many people are able to go outside and enjoy the warmer weather; but many will be sheltering themselves indoors or slathering on layers of sunscreen when they do venture out.

While over exposure to the sun can contribute to skin cancer and melanoma, avoiding the sun entirely by staying indoors, covering up with protective clothing or applying excess sunscreen can be just as bad or potentially worse for a person’s health.

It’s about moderation and balance. The sun is crucial for all life on our planet. In humans, exposure to the sun is vital for production of vitamin D, which helps lower the risk of developing serious diseases such as cancer, heart disease, diabetes, multiple sclerosis and osteoporosis.

Vitamin D supplementation can improve health, lower disease risk
May 30, 2016

ORLANDO, Fla. — Vitamin D deficiency is likely the most common medical condition worldwide, and treatment requires a combination of proper diet, supplementation and “sensible” sun exposure, according to a speaker here.

Speaking at the AACE Annual Scientific and Clinical Congress, Michael F. Holick, PhD, MD, professor of medicine, physiology and biophysics and director of the general clinical research unit and the Bone Health Care Clinic at Boston University Medical Center, outlined the many “myths” surrounding vitamin D, including a commonly held belief that high levels of vitamin D supplementation can cause toxicity, leading to hypercalcemia.

In fact, it is very difficult to become vitamin D intoxicated, and most infants, children and adults fall far short of where their 25-hydroxyvitamin D levels should be, Holick said. The health risks of vitamin D deficiency are far greater than many realize.

Vitamin D does not affect only bone health, Holick said.

“Rickets is the tip of the iceberg,” Holick said during his presentation. “Osteomalacia, diabetes, multiple sclerosis, rheumatoid arthritis, infectious diseases, hypertension, heart disease, common cancers, have all been associated with vitamin D deficiency.”

New study questions sun avoidance in northern latitude countries like Canada
May 26, 2016

Toronto – With summer just around the corner, a new study out of the Netherlands has questioned if sun-avoidance advice actually benefits a person’s general health.

In the study “Sunlight: For Better or For Worse? A Review of Positive and Negative Effects of Sun Exposure,” Dr. Han van der Rhee and his team reviewed 115 studies and found that there is no unequivocal scientific proof that eliminating time spent in the sun has a beneficial effect on the human body.

The researchers found that the present ‘epidemic’ of skin cancer is mainly caused by the increase of intermittent sun exposure, coinciding with the decrease of chronic exposure. Meaning that most people are just not outside in the sun on a regular daily basis. The researchers claim that it’s unlikely that continuous protection during daily life contributes to our health, particularly in countries with a temperate climate, and warns that both too much and too little sunlight may be harmful to our health.

High Blood Levels Of Vitamin D Help Protect Women Over 50 From Cancer: Study
May 19, 2016

Over the next two decades, researchers predict new cases of cancer will increase to 22 million annually throughout the globe. Meanwhile, in the United States alone, scientists estimate more than 1.68 million new diagnoses and nearly 600,000 deaths will occur in 2016. What can slow this malignant spread? A new UC San Diego School of Medicine study focusing exclusively on women suggests the sunshine vitamin could apply the brakes.

Higher levels of vitamin D in the blood is associated with a reduced risk of cancer, the researchers said. Specifically, women over the age of 55 whose 25-hydroxyvitamin D blood concentrations were 40 nanograms per milliliter (ng/ml) or higher showed a 67 percent lower risk of cancer than those with levels of 20 ng/ml or less.

Sunny vacations could be key to boosting vitamin D levels: study
May 19, 2016

New research suggests that taking holidays abroad may be the the key to increasing levels of vitamin D thanks to an increased exposure to the sun.

The team of researchers from the University of Edinburgh compared vitamin D levels in mainland Scotland to those in Orkney, a group of islands north of mainland Scotland.

Vitamin D is already known to have many health benefits including improved bone health, lower blood pressure, reduced heart disease risk and better chances of surviving cancer.

A deficiency in the vitamin has also been strongly linked to diseases including multiple sclerosis. Scotland has one of the world's highest levels of MS, with Orkney known to have the highest rate of multiple sclerosis (MS) in the world.

Putting the Risk of Vitamin D Toxicity into Perspective
Mar 31, 2016

by Samantha Kimball, PhD, MLT

Vitamin D is unique among nutrients. Vitamin D is actually more of a hormone than a vitamin. Vitamin D is used by nearly every cell in the body. It can be obtained naturally from the sun or by ingesting it. It was named a “vitamin” when it was discovered that many people were deficient and it could be obtained from their diet, this happened because they were not getting enough from sun exposure. This is more prevalent today than ever.

If you are lucky enough to live near the equator, where you can synthesize vitamin D year-round, and you spend a minimal amount of time unprotected in the sun and fully exposed (15 minutes in a bathing suit) each day, you probably get enough vitamin D from that ball of life in the sky. However, we Canadians are not so lucky. Our northern climate means that in the winter the sun isn’t powerful enough for our bodies to make vitamin D at all and in the summer months, when it is possible to make vitamin D, most people wear sunscreen which blocks the sun and the production of vitamin D. With our extremely limited ability to obtain vitamin D naturally we need to supplement.

There is a continuous debate among vitamin D experts about how much vitamin D you need to take to be healthy. Opinions and comments like “Vitamin D has health benefits,” but “you shouldn’t take too much because it is just too risky!” are confusing and often portrayed in parallel in the media. What is missing is a little perspective.

How much vitamin D should I take?
Jan 14, 2016

This is the most common question for vitamin D. Recommending, calculating or finding the right dose of vitamin D intake for anyone is difficult. That’s because it’s complicated!

Why? Because everyone is different. Different weights, genetics, skin colour, diets, UV exposure etc. What research has shown us is that the same D3 supplementation dose given to a group of people will result in a wide range of vitamin D blood levels as determined through 25(OH)D testing.

Here is a chart published by GrassrootsHealth which shows vitamin D levels by D3 supplementation dose taken. You can see that the same dose provides a huge variation in vitamin D blood levels. How can anyone really predict where you will fall in this chart?

Recently a new Canadian research paper1 was published in the peer reviewed journal Nutrients, by a group of researchers from the University of Alberta (Veuglers 2015). They used a dual approach and a review of 108 published estimates of vitamin D supplementation to determine the optimal vitamin D dose that minimizes the risk for both a low and high vitamin D blood level.

The vitamin D debate is not likely to disappear
Dec 04, 2015

by Samantha Kimball, PhD, MLT

 There seems to be a line drawn in the sand with respect to the debate concerning what the optimal levels of vitamin D are for health, and neither side wants to budge. On one side of the line of the current debate are those who support the recommendations officially set by government agencies.  However, most of the researchers who actively study vitamin D consider the latest official advice to be inadequate.  

There has been contention about the vitamin D recommendations made by the Institute of Medicine (IOM, which advises both Health Canada and the United States Food and Drug Administration).  The IOM released its updated report for vitamin D and calcium in 2010. Yet several groups of vitamin D experts suggest that people should achieve ‘optimal’ levels of vitamin D status, levels that are considerably higher than the ones the IOM recommendations are based on. The IOM’s Recommended Daily Allowance (RDA) of 600 IU/d was calculated to achieve adequate vitamin D status which was determined to be serum 25-hydroxyvitamin D levels [25(OH)D] of 50 nmol/L in 97.5% of the population. On the other hand, the Endocrine Society, Osteoporosis Canada, American Geriatrics society and the European Vitamin D Association all recommend target 25(OH)D levels of at least 75 nmol/L. The Vitamin D Society, Grassroots Health and the Vitamin D Council recommend that 25(OH)D levels be maintained above 100 nmol/L which require intakes well above the RDA and even above the tolerable upper level of intake (UL) in overweight and obese individuals. Why would the subject matter experts disagree with the IOM so openly?

MAY IS NATIONAL SUNSHINE MONTH

NEWS RELEASE
For Immediate Distribution

Research shows increases in sun exposure correlates with positive health outcomes

TORONTO. Ont. (May 6, 2016) – In an effort to increase public awareness of the importance of sunshine to human health, the Vitamin D Society today announced its support of a new GrassrootsHealth-led public health initiative, declaring May as “National Sunshine Month.”

According to GrassrootsHealth, with the transition from an agrarian to a technology-driven society, and other shifts in cultural behavior over the past several decades, people spend more time indoors than at any time in human history. The resulting decrease in exposure to sunlight is inhibiting our ability to fight many life-threatening diseases, including diabetes, colon cancer, breast cancer and, ironically, even skin cancer.

“Missing sunlight puts us at serious risk of a multitude of dangerous health problems,” says Carole Baggerly, Director of GrassrootsHealth. “It is essential that we improve public understanding of the need for sunshine exposure and health outcomes.”

Over the next four weeks, GrassrootsHealth’s experts in the medical and scientific communities will educate the public and those in the medical and healthcare fields on why the sun is essential for public health. This will include the launch of GrassrootsHealth’s newest program, “Harness the Power of the Sun for Health,” which will provide software for individuals to assess their current situation, set sunshine goals and track vitamin D levels and health outcomes.

Vitamin D Society urges re-examination of sun safety guidelines

TORONTO, Ont. (April 27, 2016) – Swedish women who avoid sunshine shorten their lifespans by the same amount as smoking.  This latest research was just published in the Journal of Internal Medicine. Like the Swedes, Canadians need to balance the benefits of sun exposure with the risks. It is not healthy to avoid sunshine, which provides the ultraviolet light that makes vitamin D, says the Vitamin D Society.

Between 1990 and 1992, 30,000 Swedish women were surveyed about risk factors for malignant melanoma the worst form of skin cancer.  For the next 20 years, the women’s death records were followed.  Those women with active sun exposure habits were at a lower risk of death from cardiovascular disease and causes of death other than cancer or heart disease, causes such as diabetes, multiple sclerosis and pulmonary disease.

Compared to those with the highest sun exposure, life expectancy for women who avoided sun was shorter by .6 to 2.1 years.

The lead author of the report, Dr. Pelle Lindqvist, put it another way: “We found smokers in the highest sun exposure group were at a similar risk as non-smokers avoiding sun exposure, indicating avoidance of sun exposure to be a risk factor of the same magnitude as smoking.” He went on to conclude that, “Guidelines being too restrictive regarding sun exposure may do more harm than good for health.”
