(NaturalNews)fatty acids are “incredibly potent” anti-inflammatories, which may explain why they have been linked with lowered rates of diabetes and heart disease, according to a study conducted by researchers from the University of California-San Diego and published in the journalCell.
In an experiment conducted on mice, the researchers examined how omega-3s interact with specialized white blood cells known as macrophages, which digest harmful molecules and cellular debris. As part of their operation, macrophages naturally secrete chemicals that produce an inflammatory response.
The researchers found that macrophages contain anomega-3receptor, GPR120, that causes them to stop producing these inflammatory chemicals.
In a second experiment, the researchers genetically modified a group mice to lack a GPR120 receptor, then fed a high-fatdietto both modified and normal mice. All the mice became obese and developed diabetes. When their diets were then supplemented withomega-3s, only the non-modified mice exhibited improvement in their symptoms. In these mice,supplementation was as effective at restoring insulin sensitivity as the drug Avandia.
“It’s just an incredibly potent effect,” researcher Jerrold Olefsky said. “Theomega-3 fatty acidsswitch on the receptor, killing the inflammatory response.
“This is nature at work. The receptor evolved to respond to anaturalproduct — omega-3fatty acids– so that the inflammatory process can be controlled. Our work shows how fish oils safely do this, and suggests a possible way to treating the serious problems ofinflammationin obesity and in conditions like diabetes, cancer and cardiovasculardiseasethrough simple dietary supplementation.”
fatty acids naturally occur in fishoiland in some vegetable foods such as canola oil, flax seeds, chia, kiwifruit, and purslane. Many researchers now believe that the average Western diet contains a lower content of these oils than is necessary for optimal health.

Studies detail possible benefits offatty acids for dogs with arthritis
(Animal Radio® Newsroom- March 05, 2010) - A series of studies published in the Journal of the American Veterinary Medical Association (JAVMA) offers new insights into the possible benefits derived from feeding foods containing high fatty acid concentrations to dogs with osteoarthritis.
The results of the three studies, according to contributing author Dr. Kevin Hahn, director of research and chief medical officer at Hill’s Pet Nutrition Inc., show that the dogs that were fed the foods experienced less pain associated with the disease and greater mobility.
“Many of us write off mobility problems in dogs as a part of the aging process,” Hahn said. “These studies demonstrate that feeding a food containingfatty acids to a dog with osteoarthritis significantly improves mobility and quality of life. All three studies showed significant mobility improvement as assessed by either pet owners, veterinarians, or both.”
The studies, published in the January 1, 2010, and March 1, 2010, issues of JAVMA, included 274 dogs with osteoarthritis that took part in clinical studies at dozens of privately owned veterinary clinics and two university veterinary clinics. The researchers focused on three areas: the effects of nonsteroidal anti-inflammatory drug (NSAID) dosage in dogs with osteoarthritis.fatty acids on clinical signs of osteoarthritis in dogs; the effects of fatty acids on weight bearing in dogs with the disease; and the effects of fatty acids on
In the first study, dogs with chronic pain associated with osteoarthritis showed improvements in their ability to play and rise from rest at six weeks after being switched to a diet containing high concentrations of fish oilfatty acids. The second study showed that limb strength in dogs improved with dietary intervention, Hahn said.
In the third study, veterinarians were able to reduce the dosage of carprofen, a common NSAID used for pain relief in dogs with osteoarthritis, while still providing pain relief to dogs that were fed food supplemented with fatty acids.
These studies show thatfatty acids provide pain relief and improve mobility in dogs with osteoarthritis. They also indicate that proper use of a food containing a sufficient amount of fatty acids may result in a lower dosage of medication required to manage joint pain and improve mobility in a dog with osteoarthritis. This finding is especially important because it allows veterinarians to better understand that complications that may arise from pain relief medications could be reduced when the medications are used in combination with proper nutrition.
“First and foremost, dog owners should always rely on their veterinarian when making decisions regarding their pet’s health,” Hahn said. “But it’s also very important for dog owners to know that osteoarthritis can be a silent and unrecognized problem that affects both the pet’s and the owner’s quality of life. With proper nutritional intervention, we can enrich and lengthen that special relationship between people and their pets.”
