"Eating fish, already known to be good for your heart, may also help protect your bones against osteoporosis—but the interactions between the fats found in fish and bone mass are complicated, according to new research. Scientists from Tufts, Northeastern, Harvard and Boston University took a fresh look at data from the Framingham Osteoporosis Study following 623 older adults (average age 75) over four years. In general, those with the highest fish intake (three or more weekly servings), especially darker-fleshed fish, experienced lower loss of bone density.
Darker-fleshed fish, which are highest in the healthy omega-3 fatty acids EPA and DHA, include salmon, mackerel, sardines, swordfish and bluefish. Although some of these fish, such as mackerel and swordfish, raise red flags for possible mercury contamination, this is less of a concern for the older people most at risk of osteoporosis than for pregnant and nursing women."
