Vitamin D has long been thought to protect against loss and damage of the brain’s neurons, and new research confirms that idea.*
A study from Duke University has found an association between low levels of vitamin D and an increased risk of impairment and cognitive decline in elderly subjects.
More than 1,200 participants 60 years or older from the Chinese Longitudinal Health Longevity Survey were involved in the first large-scale prospective research in Asia. Baseline vitamin D levels were measured at the beginning of the study and cognitive abilities were observed over the next two years.
The results showed that those with lower vitamin D were about twice as likely to show significant indications of cognitive decline over the course of the study. Participants’ gender and specific age had no bearing on the results.
Editor’s Note: This study should prompt further research into the precise mechanism by which vitamin D protects neurons, as it could lead to the discovery of treatments and interventions to fight the growing rate of cognitive decline seen in the elderly.
Decreased Vitamin D and Elevated Bladder Cancer Risk
The conclusion of a systematic review reported at the Society for Endocrinology annual conference in Brighton, England, adds evidence to an association between vitamin D deficiency and an increased risk of bladder cancer.*
Dr. Rosemary Bland and colleagues reviewed seven studies whose subjects ranged in number from 112 to 1,125. Five of the studies found associations between decreased serum 25-hydroxyvitamin D levels and a higher risk of bladder cancer. Additionally, higher vitamin D levels were associated with improved bladder cancer outcomes and survival.
To investigate their hypothesis, the team evaluated the expression of vitamin D signaling components and synthesis of the active form of vitamin D in human transitional epithelial cells, which line the bladder. They discovered that the cells have the capacity to activate and respond to vitamin D, which then stimulates an immune system response.
Editor’s Note: “More clinical studies are required to test this association, but our work suggests that low levels of vitamin D in the blood may prevent the cells within the bladder from stimulating an adequate response to abnormal cells,” Dr. Bland explained. “As vitamin D is cheap and safe, its potential use in cancer prevention is exciting and could potentially impact the lives of many people.”
Cooking Affect Vitamins in Food?- Thomas DeLauer
Does Cooking Affect Vitamins in Food?- Thomas DeLauer For a short time, I'm opening a VERY select few slots for nutrition consultations via Skype, fill out a contact form at http://www.ThomasDeLauer.com Vitamins - Overview: a. We all know that vitamins are important for us. Vitamins play a crucial role in our metabolism, aiding in the breakdown of food and release of nutrients that you consume. Vitamins play a function in growth, which includes physical gains from working out, energy levels, which are crucial to maintain in order to perform at your highest level, and even your general health, helping to fight off infections and prevent cancer. Given the importance of vitamins, it is very important that you consume food in such a way as to absorb them in the most beneficial way possible.
