Processing Chemical Used in Tofu May Increase Risk of Dementia in the Elderly - 0 views

  •  
    "(NaturalNews) Regularly eating high levels of tofu may increase the risk of the memory loss associated with dementia, according to a new study conducted by researchers from Loughborough University in the United Kingdom, and published in the journal Dementias and Geriatric Cognitive Disorders.

    Prior research has found that women over the age of 65 who receive hormone therapy may double their risk of dementia. This may occur because estrogen promotes cell growth, which may actually do damage to the aging brain, Hogervorst said. Alternately, high levels of estrogen might enhance the cell-damaging effects of free radicals.

    Hogervorst also noted that much of tofu consumed by study participants might have been preserved with formaldehyde, a common practice in Indonesia. Formaldehyde has been strongly linked to various forms of cell damage, and might be responsible for the memory effects observed.

    Prior research has found that older Japanese-American men who consumed high levels of tofu are also at an elevated risk for dementia, however.
    Researchers investigated the connection between memory loss and diet for 719 elderly urban and rural residents of Java, Indonesia. The found that those who ate tofu at least once per day performed significantly worse on memory tests than those who ate tofu less frequently. The effect was particularly strong among those over the age of 68."

Effects Of Vitamin D Deficiency Amplified By Shortage Of Estrogen - 0 views

    "Researchers at Johns Hopkins are reporting what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone.

    In a national study in 1010 men, to be presented Nov. 15 at the American Heart Association's (AHA) annual Scientific Sessions in Orlando, researchers say the new findings build on previous studies showing that deficiencies in vitamin D and low levels of estrogen, found naturally in differing amounts in men and women, were independent risk factors for hardened and narrowed arteries and weakened bones. Vitamin D is an essential part to keeping the body healthy, and can be obtained from fortified foods, such as milk and cereals, and by exposure to sunlight.

Low Vitamin D Levels May Raise Heart Risk - 0 views

    "Study Shows Vitamin D Supplements May Be Useful in Preventing Heart Disease

    Nov. 16, 2009 (Orlando, Fla.) -- Some men with low levels of vitamin D in their blood are at particularly high risk of developing heart disease and weakened bones that can lead to osteoporosis, researchers report.

    In a study of more than 1,000 men, those with low levels of both vitamin D and the sex hormone estrogen were at significantly increased risk of having cardiovascular disease, says study head Erin Michos, MD, a cardiologist at Johns Hopkins.

    "They were also at dramatically increased risk of osteopenia," or bone loss that can lead to osteoporosis, she says.

    "Our results suggest that vitamin D supplements, which are already prescribed to treat osteoporosis, may also be useful in preventing heart disease," Michos tells WebMD.

    Men with low levels of vitamin D and testosterone, on the other hand, were not at heightened risk for heart disease or osteopenia."

    This study suggests that vitamin D is associated with a reduced risk of breast cancer regardless of ER/PR status of the tumor. Future studies with a larger number of receptor-negative and mixed tumors are required.
