Vitamin D supplementation lowers fracture risk
Researchers have found that doses of 700 to 800 IU of vitamin D3 per day may reduce the risk of hip fracture by 26 percent and nonvertebral fracture by 23 percent.
The May 11 2005 issue of the Journal of the American Medical Association published the results of a meta-analysis of 12 clinical trials involving vitamin D supplementation in the prevention of fracture. The analysis concluded that supplementation with higher than the commonly recommended 400 international unit (IU) doses of vitamin D reduces the risk of hip and nonvertebral fractures in older individuals. The vitamin D studies included a total of 19,114 men and women aged 60 and older. The trials used the form of the vitamin known as cholecalciferol, or vitamin D3, which, according to studies cited in the current review, may be much more effective than the dietary form of the vitamin.
The researchers found that doses of 700 to 800 IU of vitamin D3 per day reduced the risk of hip fracture by 26 percent and nonvertebral fracture by 23 percent. Studies that used 400 IU vitamin D3 or less found no significant benefit for either type of fracture. The role of additional calcium supplementation could not clearly be defined from the studies, but it appears that at least 700 milligrams calcium per day may also be necessary for nonvertebral fracture prevention.

Importance of Omega 3 Fatty Acids
Omega-3 fatty acid intake is associated with lower heart disease risk
Increased consumption of omega-3 fatty acids in the diet is associated with lower levels of inflammation and endothelial activation, according to results from a study at Harvard. Dysfunction of the endothelium, which is the inner lining of the blood vessel wall, is an early event in the development of atherosclerosis and subsequent heart disease. Food frequency questionnaires completed in1986 and 1990 by 727 participants in the Nurses' Health study were evaluated for levels of the omega-3 fatty acids alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Alpha-linolenic acid consumption was found to be inversely associated with several plasma markers of inflammation, while EPA and DHA intake was inversely related to platelet aggregration. Results of this study indicate that in addition to reducing triglycerides, platelet aggregation and heart arrhythmias, omega-3 fatty acids may also reduce the body's production of hydrogen peroxide, which is involved in the inflammatory process.
J Nutr 2004 Jul;134(7):1806-11
A good source of the Omega 3's is flax seed oil or fish oil capsules. Look at my website for information on a re-formulated fish oil product with lemon juice added to reduce the "tuna fish" burps, and Vitamin D as also been added. As you can see from the blog entry last week Vitamin D is also becoming a critical nutrient that we and our children are in more need of. 20 minutes a day in the sunlight helps to maufacture Vitamin D in our system. This is one way to get a extra dose of Vitamin D!

Have a healthy week!

New Benefits of Vitamin D
Vitamin D reduces the risk of certain cancers
A study published in the American Journal of Public Health, has found that vitamin D deficiency may account for several thousand premature deaths annually. The researchers reviewed 63 studies on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004.
The majority of studies found a protective relationship between sufficient vitamin D status and lower risk of cancer, especially in cancers of the colon, breast, prostate and ovary. Vitamin D is acquired either through the diet or through exposure to sunlight. Food sources include milk, yogurt, cheese, and fortified orange juice. A typical serving provides approximately 100 international units (IU).
Researchers suggested that people might want to consider a vitamin supplement to raise their overall intake to 1,000 IU's per day. Supplementing with additional vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunlight. The evidence suggests that improving vitamin D status through diet and supplements could reduce cancer incidence and mortality at low cost, with few or no adverse effects.
American Journal of Public Health February 2006, Vol 96, No. 2:252-261.
