Dr. Yves Sauve recently discovered that DHA one of the omega-3 fatty acids contained in fish could not only lessen the risk of vision loss in older adults, but also prevent it. This loss of vision can happen because of lipofuscin, which can be toxic.
The researchers used patients suffering from macular degeneration for their study. This vision problem takes away the person's central vision. It is also the primary reason for people to go blind over 50. The results were the people that had the highest amounts of DHA had the least severe cases of macular degeneration and had a slower progression of the disease.
Sauve says that people in North America do not get enough omega-3 fatty acids is that the diet for the people consists of too many processed foods made with byproducts from corn and soy. These foods are high in omega-6 fatty acids. This gives the body more omega 6 than it should have. There should be equal amounts of omega 3 and omega 6 in the system and with processed foods there can be as much as 15 times more the omega 6 than the omega 3.
Why Fish Oil is Beneficial for the Eyes
Dr. Yves Sauve a researcher at the University of Alberta discovered and omega-3 fatty acid known as DHA could lessen and possibly prevent vision loss a patient suffers from an accumulation of lipofuscin a toxic substance that can form in the eyes. Only the studies we have performed with DHA have found where this accumulation is preventable with this omega-fatty acid.
Sauve recommends that people build up their levels of DHA by eating salmon and other oily fish or ingesting fish oil capsule 3 times a day with meals. There are suitable vegetarian sources of DHA also at health food stores, the fish do not produce their own DHA they actually extract it from the micro-algae.
Studies show indication that omega-3 fatty acids safeguard the eyes against problems such as dry eye syndrome, macular degeneration and help the eye to drain properly to lower the risk of glaucoma.
Why Fish Oil Benefits Eye Development in Infants
Omega-3 fatty acids found in fish oil help the developmental process of vision in babies. When babies get enough DHA through their formula, their vision is quite a bit better by 4 months than if they do not get the DHA-fortified formula. Pregnant women getting sufficient amounts of omega-3 fatty acids such as DHA can also have a significant effect on the vision development of an infant.
There was a study written up in the American Journal of Clinical Nutrition that involved Canadian researchers studied baby girls who mother took DHA supplements during their pregnancy from the fourth month on to the date of delivery, were not as prone to a vision deficiency at 2 months old compared those girls who mothers did not have the supplementation.
How Fatty Acids Help Dry Eyes
Dry eyes can affect you in the warm months of the year. This is when the natural moisture in the eyes is not enough for the eyes to function normally. This condition can vary from person to person, but some of the most common symptoms that occur are eyes burning, turning red, or they feel as if something was in them when there is not. It can be quite aggravating for you to deal with this problem. Many times, people just learn to cope with the aggravation, however, now there is new information that can help you alleviate the situation.
Recent studies have shown that the omega-3 fatty acids provide people with relief for dry eyes. Mackerel, salmon, tuna and other coldwater fish can provide you with enough omega-3 fatty acids to stimulate tear production. This will also in turn reduce inflammation. Some eye drops that can help are on the market, but treating the problem from a nutritional standpoint is a much better approach.
Macular Degeneration and Fish Oil
AMD or age-related macular degeneration is the primary cause for older adults to lose their vision. If you are older and smoke too, you double your risk of getting this disease. Luckily, if you as a senior eat fish about twice a week you will cut your risk in half for coming down with AMD than those seniors who eat fish less often. Johanna Seddon MD and team conducted a studyreli in which it was found that men who ate the most fish at the rate of at least two servings a week cut their risk of AMD by 45% compared to the ones with low fish consumption.
