PLYMOUTH medical researchers have discovered a link between lack of the 'sunshine vitamin' and the onset of dementia.\n\nTeams from the city's Peninsula Medical School and the universities of Cambridge and Michigan have for the first time found a relationship between lower Vitamin D levels and cognitive impairment in older people.\n\nThe results of their large-scale study are to be published in the Journal of Geriatric Psychology and Neurology.

A new study by researchers at the University of Colorado Denver and Massachusetts General Hospital (MGH) shows vitamin D plays a vital role in reducing the risk of death associated with older age. The research, just published in the Journal of the American Geriatrics Society, evaluated the association between vitamin D levels in the blood and the death rates of those 65 and older. The study found that older adults with insufficient levels of vitamin D die from heart disease at greater rates that those with adequate levels of the vitamin.

Prospective Study of Serum 25-Hydroxyvitamin D Level, Cardiovascular Disease Mortality, and All-Cause Mortality in Older U.S. Adults. Ginde AA, Scragg R, Schwartz RS, Camargo CA Jr. J Am Geriatr Soc. 2009 Jun 22. [Epub ahead of print] PMID: 19549021 DOI: 10.1111/j.1532-5415.2009.02359.x CONCLUSION: In noninstitutionalized older adults, a group at high risk for all-cause mortality, serum 25(OH)D levels had an independent, inverse association with CVD and all-cause mortality. Randomized controlled trials of vitamin D supplementation in older adults are warranted to determine whether this association is causal and reversible.

High tofu intake is associated with worse memory in elderly Indonesian men and women. Hogervorst E, Sadjimim T, Yesufu A, Kreager P, Rahardjo TB. Dement Geriatr Cogn Disord. 2008;26(1):50-7. Epub 2008 Jun 27. PMID: 18583909 DOI: 10.1159/000141484 CONCLUSION: The results for tofu consumption as a risk factor for low memory function may tie in with the Honolulu Asia Aging Study data. It is unclear whether these negative associations could be attributed to potential toxins or to its phytoestrogen levels. Estrogen (through which receptors phytoestrogens can exert effects) was found to increase dementia risk in women over 65 years of age. Tempe contains high levels of phytoestrogens, but (due to fermentation) also exhibits high folate levels which may exert protective effects. Future studies should validate these findings and investigate potential mechanisms.

"(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 supplementation on strength, physical performance, and falls in older persons: a systematic review. Latham NK, Anderson CS, Reid IR. J Am Geriatr Soc. 2003 Sep;51(9):1219-26. Review. PMID: 12919233 DOI: 10.1046/j.1532-5415.2003.51405. Conclusion: Although there is insufficient evidence that vitamin D supplementation alone improves physical performance in older people, some data suggest a benefit from vitamin D combined with calcium supplementation, but this requires confirmation in large, well-designed trials.

The program has enhanced access to healthful foods among low-income families, generated high levels of satisfaction among these families, and, according to anecdotal reports, improved the diet and overall health of those served.
