The American Academy of Dermatology (Academy) recently issued an updated position statement on vitamin D after an updated review of the increasing body of scientific literature on this vitamin and its importance for optimal health.

The Academy continues to recommend that the public obtain vitamin D from nutritional sources and dietary supplements, and not from unprotected exposure to ultraviolet (UV) radiation from the sun or indoor tanning devices, as UV radiation is a known risk factor for the development of skin cancer.

Benefits Of Fish Oil Cancelled By High-Fat Diet

Jul 14 2009 - 12:20pm

Fish oil (EPA & DHA) supplementation helped the heart when paired with a low-fat diet, but not when added to a high saturated-fat diet fed to rats with heart failure, according to a study in Hypertension: Journal of the American Heart Association.

A group of six researchers from different institutions, led by William C. Stanley, Ph.D., from the University of Maryland-Baltimore, hypothesized that when the heart is stressed, such as in heart failure, a high-fat diet may block the heart cells’ ability to absorb the heart-healthy omega-3 polyunsaturated fatty acids (PUFAs) found in fish oil.

Jun 24 2009 - 10:25am

The potential health benefits of vitamin D and marine omega-3 fatty acids are receiving increasing attention in both the media and medical field; however, definitive evidence on the health benefits and risks of these supplements is not yet available. Researchers at Brigham and Women's Hospital (BWH) will soon launch the largest randomized trial of vitamin D and omega-3s in the primary prevention of chronic disease.

Important Labelling Information For Iron-Containing Products

Jun 11 2009 - 9:51am

Health Canada is advising Canadians to carefully read the labelling of iron supplement products as there is potential for confusion about dosage. Products currently on the Canadian market display the dose in different ways on the product label and consumers may misinterpret the amount of iron in the product and potentially take an incorrect dose. The potential for harm from consuming too much iron includes adverse effects such as constipation, nausea, vomiting and diarrhea.

At very high doses, iron may cause serious harm. Children may be particularly at risk for overdose.

Researchers at the University of Warwick say older people can reduce risk of heart disease and diabetes by spending more time outside in the sunshine. Lifestyle changes and increased age lead to vitamin D deficiency, in turn leading to metabolic syndrome, heart disease, and diabetes. The scientists suggest that older people spend less time outdoors in the sun, and wear protective clothing outdoors, putting them more at risk for heart disease and diabetes from vitamin D deficiency.

Vitamin D levels in Americans have plummeted in the last two decades. Vitamin D deficiency, which is the subject of much current research, has been linked to several disease, including multiple sclerosis, particularly pediatric multiple sclerosis. Consequently, in October 2008, the American Academy of Pediatrics doubled the minimum requirement for vitamin D in children. Several studies conducted in the last two years show an association between vitamin D deficiency and heart disease, breast cancer, prostate cancer, osteoporosis, rickets and autoimmune diseases.

Low levels of vitamin D were associated with an increased risk of high blood pressure, high blood sugar and metabolic syndrome in teenagers, researchers reported at the American Heart Association’s 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.

In the study, researchers analyzed 3,577 adolescents, 12 to 19 years old (51 percent boys), who participated in the nationally representative National Health and Nutrition Examination Survey (NHANES) conducted from 2001–2004.

Low Levels Of Vitamin B12 Increase Risk For Neural Tube Defects

Children born to women who have low blood levels of vitamin B12 shortly before and after conception may have an increased risk of a neural tube defect, according to an analysis by researchers at the National Institutes of Health, Trinity College Dublin, and the Health Research Board of Ireland.

Women with the lowest B12 levels had 5 times the risk of having a child with a neural tube defect compared to women with the highest B12 levels.

Vitamin D may emerge as an important player in the fight against winter coughs, colds and flu. University of Colorado Denver (UC Denver) School of Medicine, Massachusetts General Hospital (MGH) and Children's Hospital Boston have gathered data from a large scale study showing that vitamin D deficiency, especially during winter months, may make us more susceptible to respiratory infections.

The risk of cough, colds and flu is even higher in those with lower vitamin D levels and asthma or emphysema.

Feb 9 2009 - 4:55pm

For nearly a decade researchers worldwide have been investigating a link between vitamin D deficiency and autoimmune diseases, particularly multiple sclerosis (MS). In patients with the autoimmune hyperthyroid disorder Graves' disease the link has been explored even further with evidence suggesting that genetic polymorphism of the vitamin D receptor sometimes seen in patients with Graves' disease prevents adequate absorption of the vitamin D hormone.

Vitamin D Deficiency In Young Girls Undetected
