Tips for Better Bone Building, Part 7: Fish Oils
Relationships between dietary fatty acids and bone health are only recently becoming appreciated. A role for the fish oils in bone certainly is suggested by their appearance within bone tissue. In the presence of the fatty acid eicosapentaenoic acid (EPA), bone cells display a healthy normalization of the immune response and secrete less of the bone resorption-promoting prostaglandin E2 (PGE2) when stimulated by the chemical messenger interleukin-1. Feeding rats fish oils decreases the rate of bone loss that results experimentally from a calcium-deficient diet. The bone mineral density of the hip in men and of the hip and spine in women were reported to be directly proportional to the average daily intake of fish oils.13 Although the results of dietary supplementation studies in humans have not yet been reported, the available evidence all points toward an important bone health-enhancing effect of fish oils.
