By probing the effect that vitamin D-3 has on the cells that make up the lining of blood vessels, scientists at Ohio State University in Columbus have identified for the first time the role that the "sunshine vitamin" plays in preserving cardiovascular health. In a paper published in the International Journal of Nanomedicine, they describe how they used nanosensors and a cell model to identify the molecular mechanisms that vitamin can D-3 trigger in the endothelium, which is the thin layer of tissue that lines blood vessels. It was previously believed that the endothelium served no other purpose than to act as an inert "wrapper" of the vascular system, allowing both water and electrolytes to pass in and out of the bloodstream. However, advances over the past 30 years have revealed that the endothelium acts more like an organ that lines the whole of the circulatory system from the "heart to the smallest capillaries," and whose cells carry out many unique biological … [Read more...] about Vitamin D-3 could ‘reverse’ damage to heart
People with irritable bowel syndrome could alleviate their symptoms by taking vitamin D supplements. This is the conclusion of a new study recently published in the European Journal of Clinical Nutrition. Irritable bowel syndrome (IBS) is a condition that affects the large intestine. Symptoms include abdominal pain, diarrhea, bloating, and constipation. It is estimated that IBS affects around 12 percent of people in the United States, and women are almost twice as likely to develop the condition as men. Precisely what causes IBS remains a mystery, though certain foods and stressful life events are some known triggers for the condition. Current treatments for IBS include diet and lifestyle changes and medications such as loperamide and laxatives, to help ease abnormal bowel movements. "IBS is a poorly understood condition which impacts severely on the quality of life of sufferers," says Dr. Bernard Corfe, of the Department of Oncology and Metabolism at the University of Sheffield in … [Read more...] about Could vitamin D supplements treat IBS?
(Natural News) Combining vitamin D-fortified foods with supplements may help ensure safe and adequate levels of the essential vitamin, a study published in the European Journal of Nutrition revealed. A team of scientists at the Technical University of Denmark pooled data from the Danish National Survey of Dietary Habits and Physical Activity (DANSDA) to carry out the study.The research team examined the individual habitual dietary vitamin D intake of up to 855 women. The experts also conducted graded intake modelling to predict how habitual diet including fish, fortified foods — such as plain yogurt, cheese, eggs and crispbread — and supplements would help increase vitamin D levels in participants. The fortified foods provided 20 micrograms of vitamin D daily, the researchers said.The results revealed that eating fortified foods and taking vitamin D supplements that provided up to 40 µg/day would enable the participants … [Read more...] about Maintaining adequate levels of vitamin D can be a challenge; research suggests eating fortified foods
Dive Brief: The drug, pharmacy benefit managers and insurance industries are all weighing in on a CMS proposal to require Part D sponsors to pass on a percentage of rebates to consumers, an effort to lower out-of-pocket drug costs. Pharmaceutical Research and Manufacturers of America (PhRMA) CEO Stephen Ubl praised the idea, saying that sharing such savings would “benefit millions of seniors, strengthen the program’s competitive incentives and generate significant government savings.” But America's Health Insurance Plans (AHIP) and the Pharmaceutical Care Management Association (PCMA) disagree, writing in comments to CMS that the proposal would actually raise costs for most Medicare beneficiaries. The insurer group argues the proposal fails to address the root problem of excessive list prices and price increases for drugs. PCMA also contends CMS does not have the legal authority to implement the proposed policies. Dive Insight: The proposal would change how … [Read more...] about Pharma, payers clash over CMS Part D drug rebate plan
(Natural News) According to scientists, “winter weight gain” could be partly caused by a lack of sunlight exposure during winter.Researchers from the University of Alberta have announced that the according to the results of their study, the fat cells under our skin shrink once exposed to the “blue light” emitted by the sun.Peter Light, the senior author of the study, said, “When the sun’s blue light wavelengths — the light we can see with our eye — penetrate our skin and reach the fat cells just beneath, lipid droplets reduce in size and are released out of the cell. In other words, our cells don’t store as much fat.”Light, who is a professor of pharmacology and the director of UAlberta’s Alberta Diabetes Institute, explains that the fact that individuals who live in a northern climate are not exposed to enough sunlight eight months in a year could be the reason for winter weight gain.The professor cautions … [Read more...] about Why do we gain weight in winter?
