Omega-3 supplements ease osteoarthritis pain in mice.
A study by Duke University researchers published in the Annals of the Rheumatic Diseases found that mice fed omega-3 fatty acid supplements had healthier joints than those fed diets high in saturated fats and omega-6 fatty acids, suggesting that certain dietary fats, and not simply body weight, can lead to osteoarthritis. *
Four-week-old mice were fed a low-fat diet or one of three high-fat diets: a diet high in saturated fat, a diet high in omega-6 fatty acids, or a diet high in omega-6 fatty acids plus a supplement of omega-3 fatty acids. At 16 weeks, the mice had surgery to induce osteoarthritis of the knee. The animals that ate an unhealthy high-fat diet developed severe arthritis and joint inflammation compared to mice fed the regular diet or the high-fat diet supplemented with omega-3 fatty acids.
"Our results suggest that dietary factors play a more significant role than mechanical factors in the link between obesity and osteoarthritis," said Farshid Guilak, senior study author.
Editor's Note: The researchers also tested the mice for how quickly small ear punch wounds healed. The wounds healed much more quickly in the mice given omega-3 fatty acids than they did in the mice that did not receive the supplement. Reference
