DHA linked to denser bones

Omega-3 fatty acids linked to denser bones in men Reuters/Scientific 3/22/07 "men who had the highest levels of omega-3s in their blood as 22-year-olds showed the greatest bone mineral density, and also built the most bone between their late teens and their early 20s...The amount of bone mineral people accumulate as adolescents and young adults is considered a key factor in whether or not they will develop the brittle bone disease osteoporosis later on, Hogstrom and his team note the American Journal of Clinical Nutrition...Animal studies have suggested omega-3 fatty acids, which are found in fish and flaxseed as well as other food sources, may promote bone formation and density...Higher blood levels of omega-3 fatty acids, especially DHA (docosahexaenoic acid), were linked to greater bone mineral density in the body and the spine at age 22. Higher levels of omega-3s were also tied to greater accumulation of spinal bone mineral density between age 16 and age 22...Omega-3 fatty acids, the authors point out, might influence bone formation by affecting calcium metabolism or the formation of collagen..."

So another study that shows why omega-3's help fight osteoporosis and other bone disorders later in life. One question I have is did these young men have fewer fractures than average due to the greater bone mineral density? If so this would be another benefit of omega 3 fatty acids.
