Omega-3 and omega-6 for healthy eyes
[mis à jour le 30 August 2007 à 17h11]
It now seems that those nutritional stars, the omega-3 fatty acids, may offer other benefits that were previously unknown! According to American researchers, these polyunsaturated fatty acids may help to protect us against disorders of the retina.
But all this is still to be confirmed as the retinopathy in question was experimentally induced… and then only in mice. The director of America’s National Eye Institute, Dr Paul A Sieving, qualifies the discovery. “We are simply exploring the potential impact of polyunsaturated fatty acids on the development and progression of retinal diseases”, he stated. Purely basic research at this stage, in fact.
To be more precise, the researchers studied the effects of omega-3 and omega-6 on the destruction of the blood vessels of the eye. The results seem to indicate that a diet rich in omega-3 and low in omega-6 “reduces the surface of the ocular zone no longer irrigated by 50%”. And this is no coincidence. The retina is a veritable reservoir of omega-3. “On its own it contains the largest concentration of this polyunsaturated acid in the human body”.
