Could a diet high in fish and flax help prevent broken hips?
Date:6/27/2013

wer risk of hip breaks in the study sample.

On the other hand, women who had the highest ratio of omega-6 to omega-3 fatty acids had nearly twice the risk of hip fractures compared to women with the lowest ratios. The current typical American diet contains between 15 and 17 times more omega-6 than omega-3, a ratio that previous research has suggested should be lowered to 4-to-1, or even 2-to-1, by increasing omega-3s, to improve overall health. The primary omega-6 fatty acid in the diet is linoleic acid, which composes about 99 percent of Americans' omega-6 intake and is found in corn, soybean, safflower and sunflower oils.

The specific omega-3 sources associated with lower risk for broken hips were ALA (alpha-linolenic acid), which comes from plant sources such as flaxseed oil and some nuts, and EPA (eicosapentaenoic acid), which is found in fatty types of fish. The other marine-sourced omega-3, DHA (docosahexaenoic acid), on its own did not have a significant link to lower hip-fracture risk, "but all three omega-3s were in the protective direction," Orchard said.

Jackson, who was a vice chair of the WHI for more than a decade, said continuing analyses of data from the WHI will dig down to the genetic influences on metabolism and absorption of nutrients, and whether such genetic differences could affect health risk factors in postmenopausal women.
