Vitamin D may play key role in preventing macular degeneration
Aug 28, 2015

Vitamin D has been studied extensively in relation to bone health as well as cancer. Now, a team led by a researcher at the University at Buffalo has discovered that vitamin D may play a significant role in eye health, specifically in the possible prevention of age-related macular degeneration, or AMD, among women who are more genetically prone to developing the sight-damaging disease.

In a paper published today (Aug. 27) in JAMA Ophthalmology online, Amy Millen, associate professor of epidemiology and environmental health in UB's School of Public Health and Health Professions, and her team found that women who are deficient in D and have a specific high-risk genotype are 6.7 times more likely to develop AMD than women with sufficient vitamin D status and no high risk genotype.

"Most people have heard that you should eat carrots to help your vision. However, there appear to be many other ways that adequate nutrition can support eye health. Having adequate vitamin D status may be one of them," says Millen, PhD, the study's lead author. "This is not a study that can, alone, prove a causal association, but it does suggest that if you're at high genetic risk for AMD, having a sufficient vitamin D status might help reduce your risk."

Gene study finds link between multiple sclerosis and low vitamin D
Aug 26, 2015

MIAMI - A major genetic study Tuesday found a link between low vitamin D and a higher risk of multiple sclerosis, a finding that experts say could lead to better treatment and prevention.

Previous observational studies have found an association between a person's level of vitamin D, which comes from sunlight and from certain foods, and MS, a debilitating autoimmune disease that affects nerves in the brain and spinal cord, and has no known cause or cure.

But the problem with these studies was that they could not prove that low vitamin D caused MS, and may indeed have been showing simply that people who were sick tended to stay inside more and get less sunlight.

Fewer Seniors Fall While Taking Vitamin D: Study
Aug 21, 2015

THURSDAY, Aug. 20, 2015 (HealthDay News) -- Delivering vitamin D supplements to homebound seniors might help lower their risk of falls, a new study suggests.

Previous research has found vitamin D plays an important role in maintaining muscle strength, and some studies have suggested vitamin D may help prevent falls, researchers say. Vitamin D is found in such foods as cheese, yogurt, egg yolks and beef liver, and the skin naturally produces the vitamin when exposed to sunlight.

"Falls in homebound older people often lead to disability and placement in a nursing home," said lead author Denise Houston, associate professor of gerontology and geriatric medicine at Wake Forest Baptist Medical Center in Winston-Salem, N.C.

Homebound seniors tend to have poor eating habits and little exposure to sunlight, putting them at increased risk for low vitamin D levels, she and her colleagues noted.

Dr. Gerry Schwalfenberg: We need some sun exposure to be healthy
Aug 17, 2015

A glass of wine with dinner is enjoyable and some studies suggest it will benefit your health. Draining a bottle a night? You may have a problem.

Indulging in an ice-cream cone while out for an evening walk is a nice treat. Sitting on the couch and devouring an entire gallon of ice cream will put you on a path to obesity and diabetes.

The same can be said for sun exposure.

There is no question that getting too much sun, burning exposure, can increase your risk of developing skin cancer.

But the answer is not abstinence. In fact, keeping yourself out of the sun entirely raises as many health risks as getting too much sun.

Why you need more vitamin D than you’re probably getting
Aug 17, 2015

Canadians live too far north to deliver enough ultraviolet light from the sun, which produces most of our vitamin D.

By: Dr. Reinhold Vieth University of Toronto, Published on Mon Aug 17 2015

Every Canadian should take a vitamin D supplement — and in my opinion, you should take far more than Health Canada recommends.

Vitamin D is crucial to bone health, but it also helps prevent or slow the spread of a surprising number of diseases and conditions, from multiple sclerosis to cancer. No matter how healthy your diet, you can’t get enough from food. And Canadians live too far north to deliver enough ultraviolet light from the sun, which produces most of our vitamin D.

Based on my research, I recommend that all adult Canadians take 2,000 IUs of vitamin D per day, and children should take at least 400 IUs in the winter. Those with darker skin are particularly at risk for low levels of D because darker skin absorbs less ultraviolet light from the sun. This is especially true when social stigma plays a role: it’s rarely talked about in public, but non-white people often tell me they avoid the sun because they don’t want to be darker.

Overly restrictive sun exposure warnings pose health risk, says new study

TORONTO, July 14, 2015 /CNW/ - Following restrictive sun exposure advice in countries with low solar intensity like Canada might in fact be harmful to your health, says the co-author of a new study on sunlight and vitamin D.

The recently published study Sunlight and Vitamin D: Necessary for Public Health by Carole Baggerly and several academic researchers, examines how organizations such as World Health Organization's International Agency for Research on Cancer and the U.S. Surgeon General call for sun avoidance, but ignore the fact that cutting out sunshine will reduce vitamin D, an essential vitamin for bone health, and create probable harm for the general population.

"Humans have adapted to sun exposure over many thousands of years and derive numerous physiological benefits from UV exposure, in addition to vitamin D," said Baggerly, executive director of GrassrootsHealth and breast cancer survivor. "These benefits are in addition to those derived from vitamin D alone and cannot be replaced by vitamin D supplements and therefore sun avoidance being recommended by the US Surgeon General, the Canadian Cancer Society, the Canadian Dermatology Association and others, is unnecessarily putting Canadians at risk."

Spring Sunshine Welcomed as Canadians Vitamin D Levels Plummet

Risk increased for a number of serious diseases

WOODSTOCK, Ont. (March 19, 2015) – A new Statistics Canada report has confirmed that 12 million Canadians have vitamin D blood levels that are below what Health Canada recommends and vitamin D levels continue to drop from previous years.

Results from the 2012 to 2013 Canadian Health Measures Survey (CHMS), released December 2014, report that 35% or 12 million Canadians have vitamin D blood levels below the Health Canada guideline of 50 nmol/L. This has increased by 3% from the previous Statistics Canada report (2009-2011) of 32%. The mean average vitamin D level for Canadians age 6-79 years has also dropped by 9.9% over the last 4 years from 68 nmol/L to 61 nmol/L. “This downward trend in vitamin D blood levels is putting more Canadians at a higher risk for many cancers including colon, breast and prostate, as well as for cardiovascular disease, diabetes, multiple sclerosis, osteoporosis and other serious diseases” stated Perry Holman, Executive Director of the Vitamin D Society.

Building consensus on optimal vitamin D levels in Canada

Key disease organizations support effort to curb vitamin D deficiency

TORONTO, Ont. (November 21, 2014) - A push to develop a Canadian Vitamin D Consesus that can be used to educate Canadians on the importance of optimal vitamin D levels for health is gaining support.

Vitamin D experts from around the world attended a workshop in Toronto earlier this month with the goal of reducing vitamin D deficiency in Canada.

A number of prominent Canadian disease organizations, including the Multiple Sclerosis Society of Canada, Osteoporosis Canada, the Canadan Breast Cancer Foundation and Prostate Cancer Canada attended the November 4 workshop on vitamin D.

"It's extemely encouraging to see momentum building behind efforts to improve education among Canadians on how to ensure they are getting enough vitamin D. Together, we can help people improve their health and reduce risk to several serious diseases," said workshop chairperson Dr. Reinhold Vieth, retired director of the Bone and Mineral Laboratory at Mount Sinai Hospital and a professor at the University of Toronto in the Department of Laboratory Medicine and Pathobiolgy.
