Diet high in fish linked to stronger bones
April 2, 2011
Older adults who eat greater amounts of fish end up preserving their bone density better than people who don't eat as much fish, a new study finds.
The study doesn't prove that such habits strengthen bones, but researchers believe that the combination of different oils in the fish protects bones from losing mass over time.
"We think omega 3 fatty acids from fish help to prevent" bone loss, said lead researcher Dr. Katherine Tucker, a professor at Northeastern University.
But her study finds that preventing bone loss is not as simple as upping the levels of omega 3 fats in people's diet.
Her group looked at surveys, collected in the 1980s and 90s, of the eating habits of more than 600 seniors who lived in Framingham, Massachusetts.
Measurements of the bone density in their hips were taken 4 years apart.
Women who ate three or more weekly servings of dark fish, such as salmon or mackerel, had smaller amounts of bone loss 4 years later, compared to women who ate less fish.
