Vitamin D plus calcium tied to longer life: study

Vitamin D plus calcium tied to longer life: study

Reuters – Older people who take vitamin D and calcium supplements may live a bit longer than their peers, according to an international review of several studies covering more than 70,000 people. Researchers writing in the Journal of Clinical Endocrinology found that older people who were given the supplements were 9 percent less likely to die over three years than those given placebo pills. Vitamin D alone had no impact on death rates. Read article

Omega-3 Lowers Inflammation in Overweight Older Adults

ScienceDaily — New research shows that omega-3 fatty acid supplements can lower inflammation in healthy, but overweight, middle-aged and older adults, suggesting that regular use of these supplements could help protect against and treat certain illnesses. Four months of omega-3 supplementation decreased one protein in the blood that signals the presence of inflammation by an average of more than 10 percent, and led to a modest decrease in one other inflammation marker.

Natural Antioxidant Can Protect Against Cardiovascular Disease

ScienceDaily — University of Minnesota Medical School researchers have collaborated with the School of Public Health and discovered an enzyme that, when found at high levels and alongside low levels of HDL (good cholesterol), can dramatically reduce the risk of cardiovascular disease. The enzyme — glutathione peroxidase, or GPx3 — is a natural antioxidant that helps protect organisms from oxidant injury and helps the body naturally repair itself. Researchers have found that patients with high levels of good cholesterol, the GPx3 enzyme does not make a significant difference. However, those patients with low levels of good cholesterol, the GPx3 enzyme could potentially be a big benefit. Read article

Phoenix decides to revisit fluoride water later

Fox10 – We’ve learned the city of Phoenix won’t meet to consider stopping water fluoridation until September. The issue was on Tuesday’s agenda, but got pushed back. If the city ends the program that adds fluoride to the water supply, it could save nearly $600,000 a year. Read article

City considers halting water fluoridation

SFNM – City councilors appear to be leaning toward a policy change that would stop the practice of adding fluoride to Santa Fe’s drinking water. The city Public Utilities Committee on Wednesday told city staff to look into “any concerns” about halting extra fluoridation to water from the city wellfield, Canyon Road Water Treatment plant and other sources.

Vitamin D Deficiency and Cancer Survival Disparities

Newswise — A paper just published in Dermato-Endocrinology suggests that vitamin D deficiency may account for unexplained disparities in cancer survival rates between African and White Americans. There is a large body of scientific literature supporting the role of solar ultraviolet-B (UVB) light and vitamin D in reducing incidence and mortality rates of many types of cancer. In addition, papers have reported that those with higher serum 25-hydroxyvitamin D concentrations when diagnosed with seven types of cancer have higher cancer-specific and all-cause survival rates.

Vitamin D Levels Linked with Breast Cancer Survival Rates

My Health News daily – The vitamin D levels in women when they are diagnosed with breast cancer may affect how long they will live, according to a new study from Belguim. Women in the study who had the highest vitamin D levels (above 30 nanograms per millileter of blood) were about half as likely to die within five years of their diagnosis as women with lower vitamin D levels (below 30 ng/ml).

US: Ginseng Fights Fatigue in Cancer

MedPage Today – Ginseng appears to counteract the fatigue often associated with cancer, according to randomized trial results. After 8 weeks taking supplements of the ground-up root, fatigue scores among cancer patients dropped 20% compared with 10% on placebo pills (P=0.003), Debra Barton RN, PhD, of the Mayo Clinic Cancer Center in Rochester, Minn., and colleagues found.

Health benefits of vitamin D dependent on type taken

Medical Xpress – New research has shown that vitamin D3 supplements could provide more benefit than the close relative vitamin D2. The findings published in the June edition of the American Journal of Clinical Nutrition could potentially lead to changes in the food industry when it comes to fortification. Vitamin D is important for bone and muscle health and there is concern that we don’t get enough of the ‘sunshine’ vitamin through exposure to sunlight or through diet. As a result, some foods are fortified with vitamin D. Fortification is usually with vitamin D2, as this is not derived from animals. Read article

Coconut Water Health Claims Not Supported, Study Says

Huffington post – A new consumer report analyzing coconut water claims it is not all it’s cracked up to be, finding that two of the three most popular brands had far fewer electrolytes than their labels indicated. Coconut water — a clear liquid extracted from green coconuts — is increasingly touted as an electrolyte-packed, natural alternative to sports drinks. But according to ConsumerLab.com, a product testing company, only one major brand actually lives up to that billing. Read article

Exercise, vitamin D may prevent falls: guidelines

Reuters – Older adults who are at high risk of falls should have physical therapy and take vitamin D supplements to reduce their chance of injury, according to new recommendations from a government-backed panel. Falling is “a common problem and it’s often overlooked because doctors may not be aware of their patients’ fall risk,” said Dr. Albert Siu, a professor at Mount Sinai School of Medicine in New York and vice co-chair of the U.S. Preventive Services Task Force (USPSTF), which came out with the recommendations on Monday.

Antioxidant Shows Promise as Treatment for Certain Features of Autism

ScienceDaily — A specific antioxidant supplement may be an effective therapy for some features of autism, according to a pilot trial from the Stanford University School of Medicine and Lucile Packard Children’s Hospital that involved 31 children with the disorder. The antioxidant, called N-Acetylcysteine, or NAC, lowered irritability in children with autism as well as reducing the children’s repetitive behaviors. The researchers emphasized that the findings must be confirmed in a larger trial before NAC can be recommended for children with autism. Read article

Vitamin D May Help in HF

Medical News – Boosting vitamin D suppressed renin, which may explain the vitamin’s benefits in heart failure, researchers found. Six weeks of supplementation dropped plasma renin activity by 1.3 nmol/L/hour, while control patients saw a 2.4 nmol/L/hour rise over the same period (P=0.002 for difference), Rudolf A. de Boer, MD, PhD, of University Medical Center Groningen, the Netherlands, and colleagues reported.

Japanese-American Men With Low Vitamin-D Diet Face Higher Stroke Risk

HealthDay News – Japanese-American men who don’t eat a diet rich in vitamin D have an increased risk of stroke later in life, according to a new, long-term study. The study included nearly 7,400 Japanese-American men living in Hawaii. They were between the ages of 45 and 68 in the mid- to late-1960s, when they were first examined and interviewed about their eating habits. Read article

Sunscreen prevents vitamin D production

Zeenews – It`s good to apply sunscreen before you step out of home in the scorching sun. But don`t use it too frequently or in large dabs, say experts after a recent research indicated that sunscreen use can increase the risk of skin cancer. “Sunscreen has its after-effects as the cream has harsh chemicals that can affect the body if not applied properly,” Bangalore-based dermatologist Parveen Khurana said.

Low vitamin D in womb linked to chubbier kids

CBC News – Children are more likely to be chubbier if their mother had low levels of vitamin D during pregnancy, a British study suggests. Children of women with low blood levels of vitamin D were leaner at birth, researchers found. But by the time they reached age six, those children had more body fat than those born to women with higher vitamin D status during pregnancy. Read article

Calcium Supplements Linked to Significantly Increased Heart Attack Risk, Study Suggests

ScienceDaily — Calcium supplements might increase the risk of having a heart attack, and should be “taken with caution,” concludes research published in the online issue of the journal Heart. Furthermore, boosting overall calcium intake from dietary sources confers no significant advantage in terms of staving off heart disease and stroke, the findings indicate. Read article

US: Folic acid tied to lower child cancer risks

Reuters Health – Rates of two rare childhood cancers declined after the U.S. began requiring grain products to be fortified with the B vitamin folic acid, a new study finds. Reported in the journal Pediatrics, the study does not prove that folic acid deserves the credit. But researchers say the findings at least offer reassurance that folic-acid fortification has not led to an increase in children’s cancers — which has been a theoretical concern. Read article

Antibiotics prevent UTIs better than probiotics

Reuters – Antibiotics are still better than probiotics at preventing urinary tract infections, but at least “good bacteria” don’t add to a person’s antibiotic resistance, a new study concludes. Recurring UTIs are common among some women and low-dose antibiotics are sometimes used to prevent them. The worry is that overuse of the drugs also reduces their effectiveness by making disease-causing bacteria like E. coli resistant. Read article

Australia – Lack of vitamin D worsens lupus

Science Alert – Lupus patients show more severe symptoms of the disease if their vitamin D levels are low, an Australian-first study has found. Systemic lupus erythematosus (SLE), which affects more than five million people worldwide, was found to be worse in vitamin D deficient SLE patients than in those with normal levels, in the study led by Professor Eric Morand, head of the Monash Lupus Clinic and Southern Clinical School at Monash Medical Centre.

UK: Sunshine and vitamin D: why cloudy skies are bad for our health

The Guardian – A study that emerged from Denmark this week may not have seemed particularly striking in itself. It does, however, add to a growing body of evidence that the paucity of sunlight in the UK for most of the year not only makes us miserable, but could actually be doing us harm. The study showed vitamin D tablets could lower blood pressure just as well as prescription medicines. It was small, but the findings were significant. Almost everyone with high blood pressure in the study had vitamin D levels that were too low. So the tablets were replacing something that was missing. Read article
