Vitamin D No Help for Bone Mass or Hip Fractures U
niversity of Pittsburgh researchers that followed 29,862 women for 11 years have found that supplementing calcium with vitamin D does not reduce hip fractures. The study, published in the Journal of Women’s Health, found that women tak- ing calcium plus vitamin D had as many hip frac- tures as women taking a placebo. Women supple- menting with more than 600 international units (IU) of vitamin D per day also had a 28 percent higher incidence of breast cancer. Because hip fractures are linked to a reduction
in bone density, these findings are compounded by a review of research published in The Lancet, which established that vitamin D supplements typically taken
with calcium did not increase bone density among elderly adults. The review ana- lyzed 23 studies among 4,082 participants, 92 percent of whom were women.
A
MULTIVITAMINS WITH SELENIUM COUNTER HIV
study published in the Journal of the American Medical Association showed that a daily multivitamin supplement with selenium significantly slows the advance of HIV among those with the virus. The researchers tested 878 asymptomatic, HIV-infected people over two years that had never taken antiretroviral medications. The test subjects were split into four groups, with members of each receiving
separate medications—multivitamins, multivitamins plus selenium, selenium alone or a placebo—for five years. The multivitamins contained vitamins B, C and E. Those given multivitamins plus selenium experienced a 54 percent reduction in
low counts of a critical immunity cell factor (called CD4) compared to the placebo group. This group also experienced a 44 percent reduction in other events known to accompany the progression of HIV, including AIDS-related deaths. The researchers concluded: “In antiviral, therapy-naive, HIV-infected adults,
24-month supplementation with a single supplement containing multivitamins and selenium was safe and significantly reduced the risk of immune decline and morbidity.”

Homemade Infant Food Reduces Kids’ Allergies
A
study published in the Journal of Allergy and Clinical Immunol-
ogy reports that infants that were fed more homemade foods comprising a higher percentage of fruits and veg- etables were less likely to develop food allergies. In assessing young- sters of the same age, researchers from the University of Southampton Medical College, in the UK, fol- lowed 41 children that had devel- oped food allergies by the age of 2, alongside 82 non-allergic infants. After tracking the toddlers’ diets with food diaries and conducting allergy testing, the researchers found that infants fed more of the healthier homemade diet had a significantly lower incidence of food allergies as toddlers.
