(NaturalNews) After menopause, women are at increased risk for the bone-weakening condition known as osteoporosis. And women who are diabetic have an even greater chance of developing the disorder. But now comes research from Egyptian scientists that suggests flaxseed oil could be a natural way to protect bone health.
The new study, recently published in the International Journal of Food Safety, Nutrition and Public Health, concludes that flaxseed oil has a beneficial effect on bone mineral density and reduces markers associated with osteoporosis. Bottom line: supplementing the diet with flaxseed oil could markedly reduce the risk of osteoporosis and be of particular benefit to post-menopausal and diabetic women.
Scientist Mer Harvi and colleagues at the National Research Center in Cairo, Egypt, investigated the impact of diabetes on bone health. Then in laboratory studies they evaluated how flaxseed oil added to the diet could delay the onset of osteoporosis.
"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."
Strong correlations have been noted between cardiovascular diseases and low bone density / osteoporosis-connections so strong that the presence of one type of pathology is considered a likely predictor of the other. This potentially causal relationship has led to the hypothesis that these conditions share core mechanisms. Recent advances in our understanding of the complimentary roles played by vitamin D3 and vitamin K2 in vascular and bone health provide support for this hypothesis, along with insight into key metabolic dysfunctions underlying cardiovascular disease and osteoporosis.
Part I of this review summarizes current research linking vitamin D deficiency to cardiovascular disease, the physiological mechanisms underlying vitamin D's cardiovascular effects, and leading vitamin D researchers' recommendations for significantly higher supplemental doses of the pro-hormone. Part II reviews the vitamin K connection to cardiovascular disease; the ways in which vitamin D and vitamin K pair up to prevent inflammation, vascular calcification and osteoporosis; and the necessity of providing vitamin K along with vitamin D to preclude adverse effects associated with hypervitaminosis D, which include vascular and other soft tissue calcification.
(SACRAMENTO, Calif.) - Osteoporosis affects many women and can cause painful, disabling and even life-threatening fractures. Researchers from the UC Davis Department of Internal Medicine are seeking a simple, inexpensive way to prevent the disease.
Strontium citrate is a widely available, over-the-counter dietary supplement promoted to "improve bone health." Strontium is a natural element found in bone in all people. Strontium citrate is another form of strontium ranelate, a proven medication prescribed across Europe and Australia to treat and prevent osteoporosis and related fractures. Unlike pharmaceuticals, strontium citrate is not a prescribed medication and is inexpensive.

Conclusions: More than half of North American women receiving therapy to treat or prevent osteoporosis have vitamin D inadequacy, underscoring the need for improved physician and public education regarding optimization of vitamin D status in this population.
"May 19, 2008 (Orlando, Florida) - A new study shows that a proactive vitamin D treatment plan should be considered when caring for all osteoporosis patients, and that such treatment might help decrease the likelihood of developing vitamin D deficiency.
Vitamin D deficiency is widespread among patients being treated for osteoporosis, and such deficiency should be treated aggressively, according to the findings presented here at the American Association of Clinical Endocrinologists 17th Annual Meeting and Clinical Congress."

"Vitamin K2 has been approved for the treatment of osteoporosis in Japan since 1995. Vitamin K2 treatment in osteoporosis has been shown to inhibit the occurrence of new bone fractures and to maintain BMD. The uniqueness of the prevention of bone fractures by vitamin K2 is that there has been no direct evidence of the relationship between increase of BMD and a decrease in the occurrence of bone fractures. A recent systematic review of seven Japanese randomized controlled trials by Cockayne has also shown that supplementation with phytonadione (Vitamin K1) and menaquinone (Vitamin K2) , particularly menaquinone-4, is associated with increased BMD and reduced fracture incidence. To confirm these results, a larger well design RCT using fractures as the primary endpoint is clearly needed."
"People with coeliac disease may be more susceptible to osteoporosis because their own immune system attacks their bone tissue, a study suggests.
Osteoporosis is a known risk of coeliac disease and has been explained by a failure to absorb calcium or vitamin D. "

AUTHORS' CONCLUSIONS: Frail older people confined to institutions may sustain fewer hip fractures if given vitamin D with calcium. Vitamin D alone is unlikely to prevent fracture. Overall there is a small but significant increase in gastrointestinal symptoms and renal disease associated with vitamin D or its analogues. Calcitriol is associated with an increased incidence of hypercalcaemia.
Many postmenopausal women are looking for alternatives to hormone therapy, especially in light of research findings in 2003 from the Women's Health Initiative. With major funding from the National Institutes of Health, this initiative studied the risks of combined estrogen and progestin therapy, among other health issues of critical importance to postmenopausal women. Of particular interest are phytoestrogens, which have been gaining popularity because they are marketed as "natural," because of the alleged health benefits they provide, and because they are available in a wide range of foods and supplements. This fact sheet provides an overview of phytoestrogens and discusses their potential role in osteoporosis prevention and treatment.

In concert with the acid-base literature, protein intake is considered to be a net acid-producing substance and thus a net negative risk factor for bone dissolution. However, substantial literature supports the beneficial effects on skeletal metabolism when higher protein levels are consumed in concert with adequate calcium, potassium, and other minerals, regardless of the source of protein (24-26). The Dietary Approaches to Stopping Hypertension (DASH) diet (27) is a calcium-rich diet that emphasizes fruits, vegetables, and low-fat dairy products. This diet underscores the importance of consuming a complement of foods from meats, grains, dairy, fruits, and vegetables as prudent for promoting optimal bone health. In the following articles, Rafferty and Lanham-New carefully review the evidence on the interaction of specific diet components that impact bone health and conclude that a balanced diet with recommended servings of dairy products and a variety of fruits and vegetables is prudent for optimal bone health. Additionally, they comment on future research directions for consideration by the scientific community.
The acid-base hypothesis: diet and bone in the Framingham Osteoporosis Study.

RESULTS: As hypothesized, magnesium, potassium, fruit and vegetable intakes were significantly associated with bone mineral density at baseline and among men, with lower bone loss over four years. In contrast to the hypothesis, higher rather than lower protein intakes were associated with lower bone loss. CONCLUSION: Together these results support the role of base forming foods and nutrients in bone maintenance. The role of protein appears to be complex and is probably dependent on the presence of other nutrients available in a mixed diet. A balanced diet with ample fruit and vegetables and adequate protein appears to be important to bone mineral density.
