itamin D may be known as the sunshine vitamin, but a new research report appearing in the Journal of Leukocyte Biology shows that it is more than that. According to the report, insufficient levels of vitamin D are related to a deficiency in our innate immune defenses that protect us from infections, neoplasias or autoimmune diseases.
In a new study, biologists report that melanocyte skin cells detect ultraviolet light using a photosensitive receptor previously thought to exist only in the eye. This eye-like ability of skin to sense light triggers the production of melanin within hours, more quickly than previously thought, in an apparent rush to protect against damage to DNA.
Vitamin D deficiency is highly prevalent in patients with Type 2 diabetes and may be associated with poor blood sugar control, according to a new study.
Blocking the function of an enzyme in the brain with a specific kind of vitamin E can prevent nerve cells from dying after a stroke, new research suggests. In a study using mouse brain cells, scientists found that the tocotrienol form of vitamin E, an alternative to the popular drugstore supplement, stopped the enzyme from...
Ultraviolet radiation from sunshine seems to thwart multiple sclerosis, but perhaps not the way most researchers had assumed, a new study in mice suggests. If validated in further research, the finding could add a twist to a hypothesis that has gained credence in recent decades.
Don't put down the red wine and vitamins just yet, but if you're taking antioxidants because you hope to live longer, consider this: a new study published in the June 2010 issue of the journal Genetics casts doubt on the theory that oxidative stress to our tissues shortens lifespan.
Calcium supplements, commonly taken by older people for osteoporosis, are associated with an increased risk of a heart attack, finds a study published online in the British Medical Journal. The results suggest that a reassessment of the role of calcium supplements in osteoporosis management is needed.
It is already known that blueberries are rich in antioxidants and vitamins. New research from the Lund University Faculty of Engineering in Sweden shows that blueberry fibre are important and can alleviate and protect against intestinal inflammations, such as ulcerative colitis...
A new study has found that Vitamin D, readily available in supplements or cod liver oil, can counter the effects of Crohn's disease. John White, an endocrinologist at the Research Institute of the McGill University Health Centre, led a team of scientists from...
In a new study, researchers from the Harvard School of Public Health (HSPH) have found that eating five or more servings of white rice per week was associated with an increased risk of type 2 diabetes. In contrast, eating two or more servings of brown rice per week was associated with a lower risk of the disease.
We all want that summer glow that comes from a day at the beach, but taking in the rays can have long-term implications for our health. Now Dr. Niva Shapira of Tel Aviv University's School of Health Professions suggests a way to make fun in the sun safer -- and it's all in our food.
